Huynhia
Huynhia is a genus of flowering plants belonging to the family Boraginaceae, from Asia.[1] It is native to Iran, North Caucasus (within Russia), Transcaucasus (or Armenia, Georgia, and Azerbaijan), and Turkey.[1] The genus was circumscribed by Werner Greuter in Willdenowia vol.11 on page 37 in 1981.[1] The position of Huynhia within the Boraginaceae family remains unresolved.[2] The genus was previously monotypic with just Huynhia pulchra (or Arnebia pulchra) in 1981 but then Huynhia purpurea was discovered in 2015.[3] Arnebia pulchra is still used in some sources.[4] The genus name of Huynhia is in honour of Kim-Lang Huynh (b.1935), a Swiss botanist working at the University of Neuchâtel.[5] DescriptionIt is a perennial herb, with a stout pleiocorm (a system of compact and perennial shoots occurring at the proximal end of the persistent primary root). It has basal and cauline (on the stem) leaves; the basal leaves are oblong and the cauline leaves are narrowly ovate. The inflorescence is a dense, bracteose cymoid (resembling a cyme). The flowers are distylous, with a divided calyx nearly to the base with the lobes obtuse, but not hardening and without thickened nerves or angular projections when in fruit. The corolla is hypocrateriform (Salver shaped), with a narrow tube, puberulent (covered with minute soft erect hairs) outside, without faucal (the throat of a calyx or corolla) scales or annulus and with a spreading limb. The stamens are inserted at 2 different levels below the throat. The stigma is capitate bilobed (like a divided pin head). The nutlets (small fruit/ seed capsules) are erect, ovoid-subglobose (in shape), apically acute and shortly beaked, ventrally keeled and finely tuberculate-scrobiculate (having very small pits).[6] Species2 known accepted species by Kew;[1]
