Octarrhena
''Octarrhena'', commonly known as grub orchids, is a genus of flowering plants from the orchid family, Orchidaceae. Plants in this genus are small, orchids with short stems, thin roots, short, thick, fleshy leaves arranged in two ranks and tiny flowers. The labellum is rigidly attached to the base of the column. There are about fifty species native to areas from Sri Lanka and Malesia to the Western Pacific. Description Orchids in the genus ''Octarrhena'' are small epiphytic, lithophytic or terrestrial herbs with thin roots and short stems with short, thick, fleshy leaves, their bases sheathing the stem. A large number of tiny, usually white, cream-coloured, yellowish or greenish flowers are arranged on a flowering stem arising from a leaf axil. The sepals and petals are free from each other, the petals usually much smaller than the sepals. The labellum is small, unlobed, rigidly fixed to the column and lacks a spur.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...

Icones Plantarum
''Icones Plantarum'' is an extensive series of published volumes of botanical illustration, initiated by Sir William Jackson Hooker. The Latin name of the work means "Illustrations of Plants". The illustrations are drawn from herbarium specimens of Hooker's herbarium, and subsequently the herbarium of Kew Gardens. Hooker was the author of the first ten volumes, produced 1837–1854. His son, Sir Joseph Dalton Hooker, was responsible for Volumes XI-XIX (most of Series III). Daniel Oliver was the editor of Volumes XX-XXIV. His successor was William Turner Thiselton-Dyer Sir William Turner Thiselton-Dyer (28 July 1843 – 23 December 1928) was a leading British botanist, and the third director of the Royal Botanic Gardens, Kew. Life and career Thiselton-Dyer was born in Westminster, London. He was a son of .... The series now comprises forty volumes.

George Henry Kendrick Thwaites
George Henry Kendrick Thwaites (9 July 1812, Bristol – 11 September 1882, Kandy) was an English botanist and entomologist. Thwaites was initially an accountant and studied botany during his spare time. He was interested particularly in the lower plants such as the algae and the cryptogams. He became a recognised botanist when he showed that the diatoms are not animals, but algae. In 1846 he was lecturer on botany at the Bristol school of pharmacy and afterwards at the medical school. In March 1849, on the death of George Gardner, Thwaites was appointed superintendent of the botanical gardens at Peradeniya, Ceylon. A position he held for thirty years, until he resigned in 1879. He was made a Fellow of the Royal Society on 1 June 1865 following the publication of his ''Enumeratio Plantarum Zeylaniæ'', – (five fasciculi 1859–64). His notes form the most valuable portion of Frederic Moore's ''Lepidoptera of Ceylon'' (3 vols 1880–1889). He established the Cinchona nurserie ...

Pieter Van Royen
Pieter van Royen (1923-2002) was a Dutch botanist. He is an author of many papers on the flora of New Guinea. Life Pieter van Royen was born in Lahat (town), Lahat, South Sumatra in Dutch East Indies. In 1933, he moved with his family from the Dutch East Indies to the Netherlands.
