K-50 may refer to:
Erica/ˈɛrᵻkə/, is a genus of roughly 860 species of flowering plants in the family Ericaceae. The English common names "heath" and "heather" are shared by some closely related genera of similar appearance. The genus Calluna was formerly included in Erica – it differs in having even smaller scale-leaves (less than 2–3 mm long), and the flower corolla being consisting of separate petals. Erica is sometimes referred to as "winter (or spring) heather" to distinguish it from Calluna "summer (or autumn) heather".
Most of the species are small shrubs from 20–150 cm (8–59 in) high, though some are taller; the tallest are E. arborea (tree heath) and E. scoparia (besom heath), both of which can reach up to 7 m (23 ft) tall. All are evergreen, with minute, needle-like leaves 2–15 mm long. Flowers are sometimes axillary, and sometimes borne in terminal umbels or spikes, and are usually outward or downward facing. The seeds are very small, and in some species may survive in the soil for decades.
Erica is a village in the northeastern Netherlands. It is located in Emmen, Drenthe. It has ca. 4800 inhabitants.
Erica began to form in 1863. A fuel shortage prompted large-scale efforts to drain the peats in the area and cut them for fuel. People were drawn to the area and canals were dug, both to drain the peat and to transport the cuts. Buckwheat was farmed on the drained peats. Now, the area's primary industry consists of greenhouse cultivation.
Many of the early inhabitants of Erica were Roman Catholic, and the area is still a Roman Catholic "stronghold".

The given name Erika, or Erica, is a feminine form of Eric, deriving from the Old Norse name Eiríkr (or Eríkr in Eastern Scandinavia due to monophthongization). The first element, ei- is derived either from the older Proto-NorseZ*aina(z) meaning "one" or "some", or from Proto-Norse *aiwa(z) meaning "fair" or "tradition". The second element -ríkr derives either from *rík(a)z meaning "ruler" or "prince" (cf. Gothic reiks), or from an even older Proto-Germanic *ríkiaz which meant "powerful" and "rich". The name is thus usually taken to mean something along the lines of "one ruler", "autocrat", "eternal ruler" or "ever powerful".
It is a common name in many Western societies. It is also a popular given name in Japan. Erica is also the name of a genus of approximately 860 species of flowering plants in the family Ericaceae, commonly known as "heaths" or "heathers" in English.
HMS or hms may refer to:
HMS M30 was a Royal Navy M29-class monitor of the First World War.
The availability of ten 6 inch Mk XII guns from the Queen Elizabeth-class battleships in 1915 prompted the Admiralty to order five scaled down versions of the M15-class monitors, which had been designed to utilise 9.2 inch guns. HMS M30 and her sisters were ordered from Harland & Wolff, Belfast in March 1915. Launched on 23 June 1915, she was completed in July 1915.
Upon completion, HMS M30 was sent to the Mediterranean. Whilst enforcing the Allied blockade in the Gulf of Smyrna, HMS M30 came under fire from the Austro-Hungarian howitzer battery 36 supporting the Turkish, and was sunk on 14 May 1916.
