monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispec ...
with just ''Huynhia pulchra'' (or ''Arnebia 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 (b.1935), a Swiss botanist working at the
University of Neuchâtel.
Description
It is a
perennial
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also wide ...
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).
