Huynhia is a genus of flowering plants belonging to the family Boraginaceae, from Asia. [1]

Contents

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]

Description

It 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]

<i>Cerinthe</i> Genus of flowering plants in the borage family Boraginaceae

Cerinthe is a genus of flowering plants in the family Boraginaceae, known as honeyworts. The genus is characterised by a calyx made up of separate, rather than fused, sepals, a tubular corolla, and the schizocarpic fruit that divides into two parts at maturity, unlike most members of the family, where the fruit splits into four nutlets. The genus has a circum-Mediterranean distribution, ranging from the Irano-Turanian Region in the east to Morocco in the west.

Roscoea purpurea is a perennial herbaceous plant occurring in the Himalayas, particularly Nepal. Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but species of Roscoea grow in much colder mountainous regions. It is sometimes grown as an ornamental plant in gardens.

<i>Coldenia</i> Genus of flowering plants

Coldenia, named after C. Colden, is a monotypic genus of flowering plants traditionally included in the borage family, Boraginaceae sensu lato. It was assigned to the subfamily Ehretioideae, but molecular data revealed it to be more closely related to the genus Cordia, so that other authors placed in Cordioideae. Subsequently, it was placed in its own family, Coldeniaceae, within the Boraginales order, by the Boraginales Working Group.

Selkirkia is a genus of flowering plants in the family Boraginaceae. Three species occur on the South American mainland and one, Selkirkia berteroi, the first of the genus to be reported, is an endemic on Robinson Crusoe Island off the coast of Chile. It was previously considered a monotypic genus.
