Habitat and Ecology. It is found in tropical lowland evergreen rain forests, peat swamp forests and along streams, near above mean sea level up to 550 m alt.
IUCN Conservation Status. Garcinia atroviridis is widely distributed from India to the Malay Peninsula and Indonesia, and has a large EOO of 1,177,468.29 km2 and AOO of 192 km2. In Thailand, this species is known from the natural distribution in the peninsular region (Pattani and Narathiwat Provinces), and has an EOO of 7120.08 km2 and AOO of 48 km2. Therefore, I consider the conservation assessment here as Least Concern (LC).
Phenology. Flowering January to May; fruiting February to August; flowering and fruiting more than once a year.
Etymology. The specific epithet
atroviridis from Latin compound words,
atro- meaning black or dark, and
viridis meaning green, refers to the colour of the leaves, dark green [
61,
62,
63].
Vernacular Name. Cha muang chang (ชะมวงช้าง) (Peninsular), Ma kham khaek (มะขามแขก) (Narathiwat); Som khaek (ส้มแขก) (Trang, Pattani); Som khwai (ส้มควาย) (Trang); Som pha ngun (ส้มพะงุน) (Pattani); Som ma won (ส้มมะวน) (Peninsular); Som ma on (ส้มมะอน) (Pattani); A-sae-ka-lu-ko (อาแซกะลูโก) (Malay-Narathiwat); Asam gelugor, Asam gelugur (the fruit), Gelugor, Gelugur, Kayu gelugur (the tree) (Malaysia, Indonesia).
Uses.
Garcinia atroviridis is commonly cultivated for its fruits in southern Thailand. The pericarp, sarcotesta, young shoots and leaves are edible and have a sour taste. The fruits are used fresh or dried, cooked or raw; the young shoots and leaves are used fresh and cooked, as a vegetable. The fruits are usually sliced, sun-dried and preserved for consumption in curries (southern Thai spicy sour yellow curries with fish: “Kaeng Som” (sour curry) or “Kaeng Lueang” (yellow sour curry)). It can be used as a pickle, tea and beverage flavouring, and it can be processed to make preserved fruit in syrup or it can be sun-dried. The fruits, young shoots and leaves are used as a sour flavouring in soups with pork, beef or fish. It can be used as a substitute for tamarinds or limes (the author’s observations and interviews), in conformity with Agarwal [
64], Bircher & Bircher [
65], Burkill [
66], Sastri [
67], and Verheij & Coronel [
50]. In Singapore, it is a tree suitable for gardens, parks and roadsides (the author’s observation).
Garcinia atroviridis (Asam keping) is an important ingredient in most Malay dishes, where it is used as a seasoning or sour relish. In addition to the Asam keping, many value-added products, including juice, candy, chutney and tea, have been developed using the fresh fruits and leaves [
68]. The fruits are too sour to be eaten raw but are tasty when stewed with sugar [
66,
67].
Medicinally, the fruits and leaves are applied to women after childbirth [
50,
66,
68] and a decoction of leaves and roots is used in the treatment of earache [
50,
64,
66,
67]. The fruits are commonly used in diets in Southeast Asia [
69]. The dried fruits are used as a fixative for dyes [
50,
64,
65,
66,
67].
Notes.
Garcinia atroviridis was named by Anderson, who cited two gatherings:
Griffith 862 from Upper Assam, Tabong and
Maingay s.n. from Malacca [
15]: 266. Following Art. 9.6 of the ICN [
23], they constitute syntypes, in conformity with Jones [
22]. Maheshwari cited the specimen “
Griffith, Kew distrib. 862” in K as the type for the name
G. atroviridis [
7]. Therefore, this name has been lectotypified, following Art. 9.3 and 9.12 of the ICN [
23]. I located the cited collection in K with barcode K000677601.
Garcinia atroviridis is a medium-sized tree, up to 27 m tall [
6], but from my field observations and examined specimens, it grows up to 20 m tall, in conformity with Jones [
22] and Kurz [
42]. The inner bark of this species has a slightly transparent to clear yellow sap [
6], but from my field observations, it has a little clear latex (colourless), in conformity with Corner [
34]. The fruits of this species have 12–16 ribs and grooves [
34], but I found 10–14-lobed and sulcate fruits in this study.

Lectotypifications. Maheshwari cited
Wallich Cat. 4861A,
4861B (CAL) from Sylhet as the type of
Garcinia lanceifolia [
7]. The type material must be from amongst the material cited in Flora Indica 1832. The material for the description must have been collected before 1815, when Roxburgh died, because even though it was only published in 1832, the R beside the name means that it is Roxburgh’s name and description from his manuscript and not one of Wallich’s later additions. It is certainly the case that any material collected by Wallich himself is very unlikely to be original material as he really only became active after Roxburgh had already died. I think this rules out the Bruce collection (H. Bruce is a plant collector for Wallich in Sylhet and Chittagong) in
4861A but the H.B.C. (Calcutta Botanic Garden) collection in
4861B could have been a Roxburgh specimen brought into the East India Company Herbarium. The problem may lie in citing the specimens as
Wallich 4861. The specimen
4861B is from H.B.C. collected by an unknown collector at an unknown time, but that it is likely to be original material. It is possible that Roxburgh described it from live plants and did not make a specimen, but I also think it is safe enough to assume this H.B.C. plant could have been from Roxburgh. I located three sheets of the specimen
4861B collected from the same locality: one sheet at K-W [K000639523] and two sheets at P [P04700745, P04700755], and following Art. 9.6 of the ICN [
23], they constitute syntypes. Among them,
Unknown collector,
East India Company Herbarium 4861B (K-W [K000639523]) is in the best condition and clearly shows the diagnostic characters for the species. It is selected here as the lectotype, following Art. 9.3 and 9.12 of the ICN [
23].
Garcinia gracilis was named by Pierre based on the type
Harmand 3618 in Herb. L. Pierre from Cambodia [
44]. I traced two sheets of the specimen
Harmand 3618 at P [P04701631, P04701635] collected from the same locality, and following Art. 9.6 of the ICN [
23], they constitute syntypes. Therefore, the complete and well preserved specimen
Harmand 3618 at P [P04701635] is selected here as the lectotype, following Art. 9.3 and 9.12 of the ICN [
23].

Habitat and Ecology. It is found in dry evergreen forests, tropical evergreen rain forests, mixed deciduous forests, along streams in dry evergreen and mixed deciduous forests and limestone, near above mean sea level up to 300(–700) m alt.
IUCN Conservation Status. Garcinia lanceifolia is widely distributed from India to Indo-China. It is known in many localities and has a large EOO of 3,157,674.46 km2 and a relatively large AOO of 140 km2. In Thailand, this species is known from the north-eastern, the south-western, the south-eastern and the peninsular regions, and has an EOO of 368,145.62 km2 and an AOO of 84 km2. This wide distribution and the number of localities from which it is known make it appropriate to consider its status as LC.
Phenology. Flowering December to April, with a peak in January to February; fruiting January to June, with a peak in March to May.
Etymology. The specific epithet
lanceifolia from Latin compound words,
lancea- meaning lance or spear, and -
folia meaning -leaved, refers to the leaf shape, lanceolate (spear-shaped). The specific epithet of its synonym,
G. gracilis is a Latin word meaning thin or slender, referring to the character of the leaves [

Vernacular Name. Ma paem (มะแปม), Mak paem (หมักแปม), Mak paem (หมากแปม) (Bueng Kan, Nong Khai, Laos); Cha maeng (ชะแมง) (Rayong); Cha mang (ชะมาง) (South-Eastern); Ma dan daeng (มะดันแดง) (Central); Salit (สลิด) (Tha Chang, Surat Thani); Assamikau, Kan tekera, Prango-arong, Prangsu, Rupohi-thekera (India-Assamese); Dieng-soh-jadu (India-Khasi); Pelte (India-Lushai); Thisuru (India-Garo).
Uses.
Garcinia lanceifolia is often cultivated for its fruits in south-eastern Thailand. The pericarp, sarcotesta, young shoots and leaves are edible and have a sour taste. The ripe fruits are edible and are used fresh in beverages and jams and in flavoured ice cream. It can be processed to make preserved fruit in syrup, or it can be sun-dried. It is often cultivated as an ornamental plant (the author’s observations and interviews). In India, it is often cultivated in villages for its fruits, which are acidic and eaten with relish. The leaves are cooked as a vegetable [

Lectotypification.
Garcinia planchonii was named by Pierre based on the type
Pierre 1313 from Vietnam [
44]. I located twelve sheets of this specimen collected from the same locality: two sheets at K [K000677692, K000742483], one sheet at L [L0700333], eight sheets at P [P04701308, P04701309, P04701312, P04701313, P04701314, P04701315, P04701316, P04701319], and one sheet at U [U1208239], and following Art. 9.6 of the ICN [
23], they constitute syntypes. Hence, the complete and well preserved specimen
Pierre 1313 at P [P04701313] is selected here as the lectotype, following Art. 9.3 and 9.12 of the ICN [
23].

Habitat and Ecology. It is found in mixed deciduous forests (with or without bamboo), dry evergreen forests, along the edges of dry evergreen and tropical evergreen rain forests, lower montane rain forests and along streams, near above mean sea level up to 1200 m alt.
IUCN Conservation Status. Garcinia pedunculata is widely distributed from India to Indo-China. It is known from many localities and has a large EOO of 2,443,268.21 km2 and a relatively large AOO of 160 km2. In Thailand, this species is known from the northern, the north-eastern, the south-western and the peninsular regions and has an EOO of 587,997.39 km2 and AOO of 116 km2. Because of this wide distribution and the number of localities, it is considered LC.
Phenology. Flowering November to March; fruiting March to August.
Etymology. The specific epithet
pedunculata is a Latin word meaning with the inflorescence supported on a distinct stalk, pedunculate [
61,
63], for this species refers to inflorescences with distinctly pedicellate male and female flowers or a solitary female flower with a distinct peduncle. The specific epithet of its synonym,
Garcinia planchonii, honours Jules Émile Planchon (1823–1888), a French botanist.
Vernacular Name. Krabue chet tua (กระบือเจ็ดตัว) (Chumphon); Ma kwat (มะกวัด) (Lampang); Ma da lot (มะดะหลอด) [
19]; Ma nang (มะนัง) (Phayao); Ma pong (มะป่อง) (Chiang Rai); Ma ping (มะปิง) (Lamphun); Som chao (ส้มเช้า) (Phangnga); Som mong (ส้มโมง) (Kamphaeng Phet); Som kan dan (ส้มกันดาร) (Nakhon Si Thammarat);
Som khwai (
ส้มควาย) (Chumphon, Ranong).
Uses.
Garcinia pedunculata is often cultivated for its fruits. The pericarp, sarcotesta, young shoots and leaves are edible and have a sour taste. Uses of this species are almost the same as
G. atroviridis. It can be used as a substitute for
G. atroviridis (the author’s observations and interviews). In India and Myanmar, the fruits are eaten raw or cooked, they contain malic acid and are used as a fixative or as a mordant for saffron dye [
64,
65,
66,
67]. In India, the timber is said to be useful, after seasoning, for making planks, beams and building purposes [
64,
67].
Notes. As for
Garcinia pedunculata, Buchanan-Hamilton published the name of the species using Roxburgh’s name [
33], but the original material is all of the material available to Buchanan-Hamilton, possibly including but not limited to any material previously used by Roxburgh. Anderson mentioned
Wallich Cat. 4860 as the type of
G. pedunculata [
15]. Wallich’s collection (East Indian Company Herbarium) numbers are known to be curated by species generally from multiple collections [
70].
Wallich Cat. 4860 represents three gatherings (three different materials collected from three different localities, which are distinguished by A, B and C, respectively). The problem may lie in citing the specimens as
Wallich 4860. The specimen
4860A is from India, Goalpara (originally “Gualpara” on the label), a Buchanan-Hamilton collection (a large collection by Francis Buchanan-Hamilton (1762–1829), largely from his survey of the Bengal Presidency (1807–1814), but also from Calcutta Botanic Garden),
4860B is from India, cultivated in H.B.C. (Calcutta Botanic Garden) and
4860C is from Sylhet collected by F. De Silva [
71]. The various collections under
East Indian Company Herbarium 4860 can only be syntypes if they are original material of the Buchanan-Hamilton protologue. It can easily be argued that Buchanan-Hamilton’s own collection is, possibly even the H.B.C. specimen, but it would appear that
4860C is not original material. Mabberley & Hamilton indicated that the type of
G. pedunculata is kept at E [
43]. I located one sheet of the specimen
Buchanan-Hamilton 1123 at E [E00438017] collected from India, Goalpara (same place, same date and same collector as
4860A), but it is not a duplicate of
4860A because it has a different number. Maheshwari has cited “
Wallich 4860, Goalpara, Bengal (CAL, proposed as neotype)” [
7]. It is indeed a mistake, while the original material is available but under the ICN Art. 9.10; this is a correctable error, and Maheshwari has effectively lectotypified the name with
Wallich Cat. 4860A (CAL). I located one sheet of the cited collection in K-W [K001104082]; therefore, it is an isolectotype.
Garcinia planchonii shares essential characters with G. pedunculata and is treated here as a new synonym.
The size of the fruits of
Garcinia pedunculata is 10–18 × 11–20 cm; the fruiting stalk is 5–6 cm long; the ovary has 8–10 locules; the fruits have 8–10 seeds; the shape of the seeds is reniform [
16,
37], but from my field observations and examined specimens, I found the size of the fruits of this species is 6–10 × 7–12 cm; the fruiting stalk is up to 4 cm long; the ovary has 7–10 locules; the fruits have 5–8 seeds; the shape of the seeds is ellipsoid.
