Rhynchosia himalensis var. craibiana (Fabaceae): Confirmed Occurrence in India with Lectotypification
摘要
Rhynchosia himalensis var. craibiana (Rehder) E. Peter (Fabaceae) is here documented from India based on examined material collected from Koti-Kanasar, Tyuni, Dehradun district, Uttarakhand (30.787741° N, 77.835224° E; ca. 2000 m). The variety is distinguished from var. himalensis by broadly ovate terminal leaflets longer than broad, racemes 4.0–10 cm long with 3–5 flowers, and a lower calyx lobe is shorter than the corolla. The examined Indian material extends the documented distribution of the taxon from China into the western Himalaya, adding to the floristic diversity of India and contributing to the understanding of Himalayan–Sino floristic linkages. Additionally, a lectotype is designated here to stabilize the name, ensuring nomenclatural clarity in accordance with the International Code of Nomenclature for algae, fungi, and plants (ICN). Given its restricted distribution in India, this confirmed presence highlights the need for further surveys to assess its conservation status.
