Ceropegia jinshaensis D.T.Liu & Z.K.Wu (Asclepiadoideae, Apocynaceae), a new species from northwestern Yunnan along the upper Yangtze river of China, is described and illustrated. This species is similar to C. meleagris H. Huber, C. dorjei C. E. C. Fischer and C. aridicola W. W. Smith, but can be distinguished easily by its leaf shape and floral features, especially the corolla shape and size, the interior of corolla tube and coronal characters.


Apocynaceae, Ceropegia, new species, Yunnan, Yangtze River


Traditionally, the genus Ceropegia Linn. (Apocynaceae, Asclepiadoideae) comprises more than 220 species which mainly occur in seasonally dry places in and around the semi-arid regions of the Old World, from China to the northern tip of Australia, India, Arabian Peninsula and southern Africa (Albers and Meve 2002, Surveswaran et al. 2009, Kambale et al. 2012, Bruyns et al. 2017). A recent phylogenetic study of Ceropegia with a far wider selection of species and more gene regions than before showed that the highly succulent stapeliads and Brachystelma R.Br. ex Sims are nested within Ceropegia. A revised and expanded classification of Ceropegia that included Brachystelma and all genera of the stapeliads was proposed with more than 700 species in 63 sections, making it by far the largest genus in the Apocynaceae (Bruyns et al. 2017).

According to the Flora of China, a total of 17 species of Ceropegia and 2 species of Brachystelma occur in China (Li et al. 1995), mainly distributed at low elevations in southwestern China and southern China.

During botanical exploration in northwestern Yunnan in 2015 and in 2018, an unknown species of Apocynaceae was collected on an open stony slope of the valley of the Jinsha River (upper part of Yangtze River). Its clear sap, tubular flower with a basal inflation, erect lobes coherent at their apices and forming a canopy and corona in two series, fit the main characters of Ceropegia in the narrow sense. After investigation of the specimens of Ceropegia from the main herbaria (PE, KUN and IBSC) in China, and careful consultation of the literature, especially newly published species from Asia (Swarupanandan and Mangaly 1992, Li et al. 1995, Albers and Meve 2002, Bhaskar 2006, Meve 2009, Kullayiswamy et al. 2013, Kidyoo 2014, 2015, 2018a, 2018b, Kidyoo and Paliyavuth 2016, 2017, Rodda and Meve 2017, Kumar et al. 2018), we concluded that this plant represents a species new to science and we describe it here.

Materials and methods

Morphological observations and measurements of the new species were carried out based on living plants and dry specimens with Vernier calipers. Literature studies included relevant monographs and recently published papers of Ceropegia (see introduction). Specimens at PE, KUN and IBSC were checked via Chinese Virtual Herbarium (CVH, and KUN (, the images of type specimens of C. meleagris H. Huber and C. dorjei C. E. C. Fischer were obtained from JSTOR Global Plants (


Taxonomic treatment

Ceropegia jinshaensis D.T.Liu & Z.K.Wu, sp. nov.

Figs 1, 2A–F


This species differs from the Nepalese C. meleagris by having heart-shaped leaves, a small and narrowed upper part of corolla tube, corolla lobes coherent at the top to form a pentagonal canopy and glabrous internal surface of corolla. It also differs from C. dorjei by having smaller corolla and differs from C. aridicola W. W. Smith by having a different shape of leaf apex, smaller flower, different corolla color and canopy structure.

Ceropegia jinshaensis is named after its type locality, which lies along the Jinsha River.

Vernacular name

Chinese mandarin: jin sha jiang diao deng hua (金沙江吊灯花).


This new species was observed flowering from July to August and fruiting from August to October.

Distribution and habitat

Ceropegia jinshaensis is currently known from two localities in NW Yunnan and grows on the open stony slope of dry-hot valley along the Jinsha River dominant by Opuntia monacantha (Willd.) Haw., Vitex negundo L. thicket and with Hibiscus aridicola J. Anthony, Hemerocallis fulva (L.) L. and Munronia pinnata (Wall.) W. Theob.

Conservation status

Only known from two gatherings. The population of type locality is ca. 0.5 km downstream from the crest of Ahai dam; the original habitat could be disturbed or changed by human activities such as road expansion and other building construction. Based on the IUCN criteria 3.1 (IUCN 2012), the conservation status is categorized as Critically Endangered (CR A3c+B2b (iii)).

Additional specimens examined

The general corolla shape of C. jinshaensis is very similar to C. meleagris which is restricted to Nepal both in respect of the inflated urceolate corolla tube at the base and the very short lobes. It differs from C. meleagris by having shorter leaf blade with cordate base, corolla lobes fused at the top into a pentagonal canopy, glabrous internal surface of entire corolla tube and shorter inner coronal lobes than outer ones. The corolla of C. jinshaensis is similar to the Bhutanese species C. dorjei. Both of them have the inflated corolla tube at the base and shorter inner lobes than outer lobes of the corona, while the present new species has heart-shaped leaves and much shorter corolla lobes than corolla tube, unlike the corolla lobes in C. dorjei which is mostly as long as the corolla tube. The dry-hot valley habitat, non-twining stem and heart-shaped leaves of C. jinshaensis remind one of the Chinese endemic C. aridicola, which occurs ca. 100 km from the type locality of this new species. However, in C. aridicola the apex of the leaf blade is acuminate, the flower is up to 1.5 cm long, the corolla tube is more than twice as long as broad and the flower color is pale green to light pink. A detailed morphological comparison is given in Table 1.

Although the last taxonomic treatment of Ceropegia in China recorded 17 species, it is essential to revise the provisional treatment provided in the Flora of China (Li et al. 1995). C. jinshaensis is the only new species of Ceropegia reported from China since the family was revised two decades ago. This new species presents a corolla with well-inflated corolla tube at base and shorter lobes and this shape is unique among all the known Ceropegia species recorded from China. It is crucial to conduct further taxonomic study on this kind of neglected group equipped with up-to-date methods and insight in order to better understand China’s plant diversity before it is too late.
