During intensive field survey in Western Ghats, Maharashtra, India, authors came across a species of Ceropegia sect. Tilioris H. Huber. It was identified as C. attenuata Hook, but recognized some new variation in flower which was not reported earlier from India which will be useful to delimit taxa. Present paper deals with note on polymorphism [1-3].

1. Introduction

The Ceropegia sect. Tilioris established by H. Huber in Mem. Sco. Brot. [4] with type species C. attenuata Hook. It comprises c, 38 species in the world distributed mainly India and south-east Asia, Malaysia (New Guinea, Philippensis) to Northern Australia [5,6]. In India, It is represented by 13 species of which 12 are endemic to peninsular India [2]. During an intensive exploration in the (Konkan) Sindhudurg, Western Ghats of Maharashtra during June to August, 2020, Author came across an interesting population of C. attenuata Hook. On examination in field as well as laboratory, it was found to be undescribed species. It was not, however it is C. attenuata Hook. with dark brown spots on basal portion on either side and mouth of carolla lobs.

After the scrutiny of literature [1-3] and careful dissections and repeated examining the live specimen in field and in laboratory, revels that it is similar to C. anantii Yadav et al. [3] due to one dark purple spot on either side at base on each corolla lobs only present in Ceropegia anantii Yadav et al. [3] and not recorded in C. attetuata Hook.

When Hooker [5] described C. attenuata Hook. based on collection of Dalzell from Bombay, Ghats near Vigorna (K000357705 & K000357706 image!) but Dalzell (on sheets) and Hooker [5] in protologue did not clearly mentioned about any dark brown spot in corolla lobs.

A critical examination and observation of reach population of low elevated hills and plateaus at Vaibhavwadi and Phonda Ghats shows 1 to 7 dark brown spots irregularly occurs on either side at base on each corolla lobs and mouth of corolla tube, spots unequal in sizes, connected each other in one line, corolla tube is green, greenish yellow, brown, sometimes.


Figure 1: Ceropegia attemuata Hook.: (a-j) - Variations in colour, shape and cage of Flower; (k)- Flower L.S.; (l-m) - Corona; (n)- Corona-top view.

corolla tube with one dark brown spot, lobs connate and free at tip in bunch of two or three may be braked due disturbance of cattle foraging, rarely or abnormally with four lobed corolla (Figure 1), outer carona entire to bilobed, hairy to glabrous margins and within, curved in inside when dry, yellow to purple to brown (colour variable at base, tip, sometimes margin purple and yellow within).


  1. Author studied attenuata Hook. from different parts of Konkan region of Western Ghats of Maharashtra, India and population study reveals that the nature, number and distribution of dark brown spots, outer carona are variable in C. attenuata Hook. which is located about 80 km away from its type locality. It is one of extremely polymorphic species of Ceropegia sect. Tilioris and those dark brown spots on corolla lobs and entire to bilobed outer carona lobs, its colour can be considered as ecological variation in C. attenuata Hook.
  2. anantii Yadav et al. [3] which is allied to former species, it opined that C. anantii Yadav et al. 3] of Ceropegia sect. Tilioris may be confused with C. attenuata Hook. in future due to presence of dark brown spots on corolla lobs but population study on type locality (Salva hills, Vaibhavwadi, district Sindhudurg) indicates that C. anantii Yadav et al. [3] is quite distinct species with dark brown spot on basal portion on either side of corolla lobs, narrow carolla tube with abruptly dilated basal part and distinctive light windows and distributed in higher altitudes.
