Cor.-tube funnel-shaped above. 

 Dome of cor.-lobes hemispherical or depressed. 



Dome hemispherical i, C. elegans. 



Dome mnch depressed 2. C. Gardneri. 



Dome of cor.-lobes semi-ovoid or oblong. 



Cor.-lobes oblong-ovate, much shorter than 



tube Z- ^. Thwaitesii. 



Cor.-lobes linear, nearly as long as tube. . 4. C. Decaisneana. 

 Cor.-tube cylindrical above. 



FI. \\-2 in., lobes about \ as long as tube . 5. C. biflora. 

 Fl. I in., lobes about \ length of tube . . 6. C. parviflora. 



The cor.-tube (in C. elegans) has a ring of stiff hairs within just above 

 its swollen base pointing downwards, and completely closing the passage : 

 small Diptera are caught in this trap.

Stems slender, elongated, 1. \-2\ in., narrowly lanceolate 

 or ovate-lanceolate, acute at base, much tapering to acute 

 apex, petiole \ in. ; fl. somewhat large, on rather long ped., 

 1-4 (often solitary); cor. i|-if in., curved, inflated base nearly 

 globose, upper part broadly funnel-shaped, lobes oblong-oval, 

 obtuse, usually ciliate with few long bristles, dome hemi- 

 spherical or nearly so; coronal lobes 10; linear, straight, a 

 little shorter than the adnate processes; follicles 6-8 in., 

 linear, very slender, membranous.

L. broader, often rounded at the base ; cor. larger, the 

 lobes usually without cilia. 



Moist and intermediate regions; rather common up to 4000 ft.

 Ekiriankumbura. Fl. Sept.-Feb.; greenish, more or less spotted and 

 stained with purple. 



Also in S. India. 



The presence or absence of cilia are very inconstant characters, and 

 the colour of the flowers and form of the leaves vary greatly. I find 

 myself quite unable to separate C. WalkercE as a species (as is done in 

 Fl. B. Ind.), and follow Thwaites in combining it with C. elegans. It was 

 first collected by Wight near Kandy, and his plate was drawn by Mrs. 

 Walker. It shows the cor.-lobes with cilia.
