Cardaminehongdeyuana is known only from two collections presumably made from one locality; its IUCN Red List category (IUCN 2001) remains uncertain and is currently assessed as Data Deficient (DD).
Cardaminehongdeyuana is named in honour of Academician Professor Hong De-yuan (14 January 1937 – ), editor-in-chief of the Pan-Himalayan flora for his help and support throughout my studies on the Brassicaceae of that flora. Cardaminehongdeyuana is most closely related to C. yunnanensisFranch., a widespread species that grows at 900 – 4200 m in Bhutan, China (Sichuan, Xizang, Yunnan), India (Sikkim), and Nepal (Zhou et al. 2001). A close comparison of the novelty with substantial material of C. yunnanensis, including its type collection (Delavay 1843: holotype, P; isotypes, E, F, P, US), reveals that they differ substantially. From the latter, C. hongdeyuana is readily distinguished by having terete (vs angled) and glabrous (vs pilose or puberulent) middle and lower stems, (5 –) 7-foliolate (vs 3 – 5 (– 7)-foliolate middle cauline leaves, exauriculate (vs auriculate) petioles 1 – 2 (vs 2 – 8.5) cm with (vs without) 2 basal glands, winged (vs wingless) petioles and petiolules, symmetric or slightly oblique (vs strongly oblique) bases of lateral leaflets(Fig. 2A, C), shorter leaf surface trichomes 0.3 – 0.4 (vs 0.7 – 0.8) mm (Fig. 2B, D), oblong (vs obovate) petals, and stigmas considerably wider than (vs as wide as) the style. Erect perennial with non-auriculate, 7-foliolate middle cauline leaves with winged petioles and petiolules, dentate-serrate leaflets glabrous abaxially and sparsely pubescent adaxially with stout trichomes much larger than marginal ones, white petals without claws, horizontal flowering pedicels with two basal glands, and capitate stigmas considerably wider than styles.
