Huynhia


Huynhia is a genus of flowering plants belonging to the family Boraginaceae, from Asia.
It is native to Iran, North Caucasus, Transcaucasus, and Turkey.
The genus was circumscribed by Werner Greuter in Willdenowia vol.11 on page 37 in 1981.
The position of Huynhia within the Boraginaceae family remains unresolved. The genus was previously monotypic with just Huynhia pulchra in 1981 but then Huynhia purpurea was discovered in 2015. Arnebia pulchra is still used in some sources.
The genus name of Huynhia is in honour of Kim-Lang Huynh, a Swiss botanist working at the University of Neuchâtel.

Description

It is a perennial herb, with a stout pleiocorm.
It has basal and cauline leaves; the basal leaves are oblong and the cauline leaves are narrowly ovate.
The inflorescence is a dense, bracteose cymoid. 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, with a narrow tube, puberulent outside, without faucal scales or annulus and with a spreading limb. The stamens are inserted at 2 different levels below the throat.
The stigma is capitate bilobed. The nutlets are erect, ovoid-subglobose, apically acute and shortly beaked, ventrally keeled and finely tuberculate-scrobiculate.
