About this ebook

The Otway region of Victoria, with its temperate rainforests, mountain ash forests, heathlands, plains and coastal dunes, has an extraordinarily rich and diverse flora. The first volume of Flora of the Otway Plain and Ranges covers the orchids, irises, lilies, grass-trees, mat-rushes and other petaloid monocotyledonous plants.

Enid Mayfield's exquisite colour illustrations of more than 200 species reveal tiny botanical details which enable the untrained botanist to identify each species with ease. The section on orchids describes and illustrates more than 130 species, highlighting their fascinating adaptations for attracting specific pollinating insects.

The clear text and illustrations frequently draw attention to the relationship of plants to the broader environment, the impact of fire, the role of pollinators and the importance of fungi.

    PETALOID MONOCOTYLEDONS

    CHARACTERISTICS OF FAMILIES

    ALISMATACEAE

    Water Plantains

    A small family of aquatic perennials; leaves with long petioles and a distinct blade; numerous small flowers on branched whorls along the stem; fruit an achene.

    ASPHODELACEAE

    Bulbines

    Often succulent-leaved herbs or occasionally small trees; flowers on pedicels; pedicels often jointed; tepals 1-nerved; fruit a capsule.

    ASTELIACEAE

    Astelias

    Plants of cool moist places; leaves linear to lanceolate, with a silvery-white coating; flowers in bracteate racemes or spikes; fruit usually a berry.

    COLCHICACEAE

    Milkmaids and Wurmbeas

    Perennial herbs usually with nectaries to attract pollinators; with a rhizome or tunicate corm and roots sometimes tuberous; each tepal encloses an anther in bud; styles deeply divided; fruit a capsule.

    HEMEROCALLIDACEAE

    Daylilies

    Perennial herbs or shrubs usually having branched flower stems with sequentially-opening, fleeting flowers; rootstock mostly a rhizome; leaves linear to ovate; anthers releasing pollen through pores or slits on the side; fruit a berry or capsule.

    HYPOXIDACEAE

    Star-flowers

    Grassland herbs with annual leaves (Hypoxis) or rainforest shrubs; leaves at base, from rhizomes or corms; flowers with six stamens, often yellow; ovary below tepals; fruit a capsule or fleshy.

    IRIDACEAE

    Irises

    Flowers are colourful and typically have six petal-like segments and three stamens; the ovary is below the tepals; the flower or group of flowers has two bracts (spathe) at the base; leaves are usually in two rows on either side of the stem and grow from corms, rhizomes or bulbs; fruit capsules split from the apex.

    LAXMANNIACEAE

    Lilies and Mat-rushes

    The members of this family look very different and it is difficult to give common characteristics linking them that are immediately visible to the eye. Flowers have six segments and are on jointed pedicels. The ovary is above the tepals.

    LUZURIAGACEAE

    Drymophilas

    Flowers are white or pale pink and have six petal-like segments; the stem is wiry; leaves are alternate, arranged in rows on either side of the stem branches and twist through 180 degrees at the base.

    XANTHORRHOEACEAE

    Grass-trees

    Plants with thick woody stems above and/or below ground; leaves are long and linear in dense tufts at the tips of the stems; flowers are arranged spirally in a massive dense spike on a woody axis.

    XYRIDACEAE

    Yellow-eyed Grasses

    Herbs of marshy areas with grass-like leaves with an open sheath at the base; flowers are borne in tough bracts in a head or dense spike, and have three petals, which are usually yellow and ephemeral.

    ORCHIDACEAE

    Orchids

    Flowers have three sepals and three petals with one petal (the labellum) usually very different from the other two; the style and stamens are united to form a column; the single fertile stamen and the stigma are on the column; pollen is usually bound together in compact packets (pollinia), which often attach by a sticky substance to the pollinating insect for ease of transfer to the next flower.

    PETALOID MONOCOTYLEDONS

    CHARACTERISTICS

    Characteristics of Petaloid Monocotyledons

    A seed is a tiny embryonic plant with a store of food and one or two seed-leafs (cotyledons), all enclosed in the seed coat. Monocotyledons have one seed-leaf and dicotyledons have two. Monocotyledons and dicotyledons are the two great divisions of the most highly evolved plants, the flowering plants (Angiosperms).

    With flowering plants (Angiosperms) the ovary arose in evolution and, unlike ferns and conifers, seeds developed in a protected chamber. At maturity, they were enclosed in a fruit, perhaps a berry or a capsule. Gradually two distinct groups differentiated, the monocotyledons and the dicotyledons. They share the characteristic ovary and enclosed seed but differ in other characteristics. Petaloid monocotyledons include lilies, irises, orchids and grass-trees. The more primitive lily-like monocotyledons have a superior ovary that sits in the centre of the flower. Irises and orchids have an inferior ovary that is beneath the flower. Non-petaloid monocotyledons include grasses, rushes and sedges.

    Flower parts are arranged in threes (rarely fours). Sepals and petals are in multiples of three. Lily-like flowers have six stamens and irises have three. The three stamens in orchids have been compressed into the column.

    The rootstock may be a rhizome, corm, or bulb. Most terrestrial orchids have an underground stem that develops tubers.

    The leaf is usually simple and undivided and grows from the base of the plant. Typically, it is narrow with parallel veins that run along its length. Rarely, it is another shape. Alisma species have a leaf blade that is ovate or elliptical but the veins are still more or less parallel, in curves that reflect the margin.
