S. DECCAN PENINSULA ; Wight (2011, 2285 Herb. Propr.). CEYLON ; Thwaites 

 (C. P., nn.257, 3354). 



A small, ramous weed. Lower leaves 1 by -| in., petioled, ovate, upper narrow 

 sometimes linear. Spikes f by \ in., nearly all terminal, markedly 1-sided ; barren 

 bracts not cuspidate. Capsule 3 in. ; seeds small, minutely verrucose. This, the 

 typical R. parviflora, Nees, appears a very rare plant ; Nees, however, referred 

 numerous specimens with the fertile bracts hairy all over to JR. parviflora, but 

 which are R. pectinata, Nees, as far as the description goes.

 1 by 5 in., terminal and axillary, clustered, subsessile, distinctly 1-sided ; barren 

 bracts ^ by T ' 5 in., scarcely margined ; fertile ^ in. diarn., orbicular, apiculate, scarious- 

 marginate, hairy on back as well as on margins ; bracteoles T ' 5 in., elliptic, subacute. 

 Calyx jlj in.; segments linear-lanceolate, pubescent. Corolla blue or whiteish, upper 

 lip short. Anther-cells superposed, lower white-tailed. The area of this abundant 

 plant should perhaps be extended to Java, &c., but the examples thence (Dicliptera 

 coerulea, Slume Bijd. 791) differ considerably from all the Indian material, which is 

 very uniform in character, the size of the heads and bracts varying a little.
