linear, stigmas 2 short hemispheric. Capmle 2-valved, separating into its 2 

 carpels, or often very thin breaking up irregularly. Seeds very small, poly- 

 hedral, dark brown, reticulated. — Species 14, chiefly Indian ; Malaya, Aus- 

 tralia, Trop. Africa and its islands. 



StrnGBinrs I. Eucanscora. Flowers in terminal dichotomous cymes, or 

 pedicelled in axillary small cymes. Ccdyx keeled or winged. CoroUa sub- 

 bUabiate. Stamens 4, one larger perfect, three shorter smaller barren or sub- 

 obsolete. 



* Oymes terminal ; bracts at its bifurcations not perfoliate. 



t Calyx striate or keeled, not vnnged, pedicels not 4r-imn</ed.

Throughout India ascending to 4000 ft., common ; from Kumaon and Bhotan to 

 Ceylon and Tenasserim. — Disteib. Malaya, Australia, and E. Tropical Africa. 



Annual, erect, 4-20 in., densely branched upwards. Leaves IJ by \ in., 3-nerved, 

 often petioled ; upper passing into the bracts. Cyme diffuse, leafy ; bracts J in. 

 leaflike, a few of the uppermost linear. Calyx | in. ; teeth lanceolate-linear. Corolla- 

 tube I in., lobes ^ in. Stamens one on the corolla-throat, perfect ; 3 rather lower 

 down with slightly shorter filaments and smaller anthers, polliniferous or not. Cap- 

 side oblong, as long as the calyx. 



Vae. tenella ; bractjs ovate herbaceous, many of the upper linear. C. tenella, 

 Wight Ic. t. 1327 ; Wall. Cat. 4362.— Malabar and Mysore, Wight.— This has the 

 bracts nearly as in the next species, but the cyme is diffuse, the pedicels long 

 slender. 



2. C decurrens, Dalz. in Hook. Kew Joum. n. 136; stem 4-winged, 

 lower leaves lanceolate or elliptic, cyme erect with ascending branches, bracts 

 in its upper part small or linear, pedicels erect, corolla rose or white. Daiz. ^

W. Dbcoan Peninsula from the Concan southwards, frequent. 

 Very doubtfully distinct from C. difusa, var. tenella. Leaves hardly decurrent. 

 Cpme subtrichotomous (in C. diffusa usually dichotomous). 



3. C. pauciflora, Dah. in Hook. Kew Joum. ii. 136 ; stem 4-winged, 

 lower leaves ovate or obovate, cyme laxly dichotomous few-flowered, branches 

 long curved ascending somewhat 4-angled, pedicels often thickened under the 

 calyx. Dalz. 8r Gibs. Bomb. Fl. 157. 0, lancifolia, Miq, in PI. Hohenack.

W. Dbccan Peninsula, from Malwan to Quilon ; Dalsell, Wight, &c. 



Lower leaves scarcely ^ in., smaller than the middle oanline. Bracts (of the lower 

 part of the cyme) rarely so much as y in., oblong or linear. — This seems very near, 

 but separable from, C. diffusa ; Wight, however, in his Herb., referred it to his C, 

 tenella (treated above as a var. of C. diffusa).
