1. C. Nag'chana, Nees in J)C. Prodr, xi. 109 ; prostrate, glabrous or 

 hoary, leaves spathulate-elliptic or obovate, flowers clustered, bracteoles 

 small linear, calyx-teeth longer than the tube, filaments glabrous, anther- 

 cells mucronate. C. depressa, T. Anders, in Thwaites Enum. 225, and in

Stems 6-18 in., branched, lineolate, sometimes obscurely scabrid. Leaves |-1 in., 

 obtuse, base attenuate ; petiole 0-| in. Bracts small, spathulate-elliptic orO; brac- 

 teoles in. Calyx lineolate, glabrous or puberulous ; tube in., teeth ^ in. Corolla 

 scarcely so long as the calyx, puberulous, flesh-coloured or blueish, palate not corru- 

 gate. Filaments connate near the base; anther-cells very shortly but distinctly 

 mucronate. Capsule % in. T. Anderson has not indicated the grounds on which he 

 keeps C. Nagchana and C. depressa distinct; Nees says C. 'Nagchana differs by 

 having the bracteoles spathulate, which is not the case in his type specimen. In C. 

 Nagchana, where the flowers are clustered, the bracts of the upper flowers are much 

 smaller, the bracteoles 0-^ in., but this is exactly as in Euellia cernua, Wall. 



2. C. littoralis, T. Anders, in Thwaites. Enum. 225, and in Journ. 



Linn. Soc. ix. 460 ; shrubby, nearly glabrous, leaves small obovate, flowers 

 solitary or 2-3 together axillary, bracteoles elliptic, calyx-teeth shorter 

 than the tube, filaments glabrous, anther-cells mucronate. Justicia madu-
