03EA87DFFF52FFEAD281A6F4FDB9FDB2.taxon	distribution	Distribution and habitat: (Figure 4) — A. chendezhaoana, endemic to China, occurs only in moist and shady gullies of the Luoxiao, Nanling, and Wuyi Mountains along the borders of Fujian, Guangdong, Hunan, and Jiangxi provinces, at elevations between 400 – 1300 m. It climbs in bushes of the evergreen broadleaved forest undergrowth. The soil is usually wet, shallow and soft, dark brown in color.	en	Zhang, Fan, Feng, Si, Zhou, Jianjun, Zhang, Rong, Liu, Linhan, Yang, Chengzi, Yu, Xunlin, Pan, Bo (2018): Apios chendezhaoana (Fabaceae), an overlooked species and a new combination from China: evidence from morphological and molecular analyses.

03EA87DFFF52FFEAD281A6F4FDB9FDB2.taxon	etymology	Etymology: — The Latin epithet is in honor of a female botanist, Mrs. Te-Chao CHEN (ḴDZffi, Chen Dezhao in Chinese pinyin), from the South China Botanical Garden, who contributed to the treatments of many legumes in the Flora of China. The Chinese name ‘ ḿṅ ’ refers to one of its main areas of distribution in China — the Nanling Mountain Range. Conservation status: — Apios priceana was listed as an endangered species in the USA because there are only 47 known populations from 22 counties in four states (Woods 2005). The situation of A. chendezhaoana is very similar to this. We have so far found only 23 specimens and 15 recorded populations from four provinces. Each population has only 1 – 10 known individuals, and each location is very remote from the next. The total number of individuals is estimated to be less than 250, allowing for undiscovered populations. Most specimens were collected decades ago and recent records are rare. Like all its allies, but unlike most legumes, this species prefers shady and undisturbed habitats, shallow and fertile soils, along creeks and streams, so it is very susceptible to human disturbance. In view of the very small number of individuals and scattered distribution, we evaluate this species as Endangered (EN D) in accordance with the IUCN Red List Categories and Criteria version 3.1 (2001) (http: // www. iucnredlist. org / static / categories _ criteria _ 3 _ 1).

03EA87DFFF56FFEBD281A41FFB84F9EE.taxon	distribution	Distribution and habitat: — Apios carnea is distributed in Bhutan, China, India, Laos, Myanmar, Nepal, Thailand, and Vietnam. It grows in forests, or along riversides and roadsides, at elevations between 600 – 3200 m above sea level. Phenology: — Flowering from July to September; fruiting from August to November. Apios bodinieri has lax nodose inflorescences, red and open flowers. It most resembles Apios carnea and only differs from the latter by its trifoliolate leaves. Occasionally A. carnea has leaves with 3 leaflets, or even 7 leaflets, so we reduce A. bodinieri to a synonym of A. carnea. Woods (1988) also included A. bodinieri within A. carnea.

Apios gracillima is unique by its linear to narrow oblong or lanceolate leaflets with rounded apex, and 2 – 4 purple flowers in each inflorescence.

Woods (1988) and Ren (2005) both came to similar conclusions as those above in their dissertations, but they did not publish their results. We therefore recognize four Apios species in Asia, i. e., A. carnea, A. chendezhaoana, A. fortunei, and A. delavayi. Three varieties of A. delavayi are recognized as well, i. e., var. dalavayi, var. gracillima, and var. pteridietorum. A morphological comparison between them is provided in Table 2.	en	Zhang, Fan, Feng, Si, Zhou, Jianjun, Zhang, Rong, Liu, Linhan, Yang, Chengzi, Yu, Xunlin, Pan, Bo (2018): Apios chendezhaoana (Fabaceae), an overlooked species and a new combination from China: evidence from morphological and molecular analyses.
