Hemipilia pinguicula is a species of flowering plant in the family Orchidaceae. It is native to south-eastern China (north-eastern Zhejiang).[1]
Description
[edit]Hemipilia pinguicula grows from an ovoid shaped tuber. It has a single stem leaf, situated near the base of the stem. The inflorescence consists of a single relatively large flower, rose-red to purple in colour, with a three-lobed lip (labellum). The upper sepal and the lateral petals are grouped to form a hood. The flower has a conical spur, longer than the lip. There are two stigmas that extend under the short rostellum.[2]
Taxonomy
[edit]The species was first described in 1878 as Gymnadenia pinguicula. It was later transferred again to Habenaria and then Amitostigma.[1] A molecular phylogenetic study in 2014, found that species of Amitostigma, Neottianthe and Ponerorchis were mixed together in a single clade, making none of the three genera monophyletic as then circumscribed. Amitostigma and Neottianthe were subsumed into Ponerorchis, with Amitostigma pinguicula becoming Ponerorchis pinguicula.[3] Later studies suggested that Ponerorchis pinguicula lay outside the main clade consisting of Hemipilia, Ponerorchis, Sirindhornia, and Tsaiorchis, and a new genus, Shizhenia, was created for it.[2][4] After some adjustment of the generic boundaries, the genus Shizhenia was synonymized with the genus Hemipilia.
