Erect or shortly creeping ; stems 3-6 in. Leaves \-^ in., sometimes somewhat 

 ovate at the base. Lower whorls of flowers often distant, upper sometimes almost spi- 

 cate. Calyx tubular ; teeth 3-5, small. Petals small, fugacious, or 0. Stamens 3-5. 

 Capsule ellipsoid, longer than broad. Seed half-obovoid, the plane face somewhat 

 excavated. Hypobrichia Spruceana, Benth. in Herb. Spruce which has been reduced 

 to a synonym of Rotala verticillaris, differs in its inflorescence and short calyx.

Stems 2-4 in., procumbent. leaves \-^ in., linear or narrow oblong, obtuse. 

 Ffawers scattered, not at all spicatc. Calyx-tube elongate-campanulate, 5-ribbed ; 

 teeth 5, triangular, acute ; teeth and sometimes the whole tube with minute scattered 

 hairs, accessory teeth 0. Petals minute. Capsule ellipsoid, much longer than broad. 

 Seed half-ellipsoid, excavated on the plane face. 



* Calyx in fruit hemispheric, tube as broad as or broader than long.

Stems tiifted, 1-3 in. Leaves \~ in., linear or narrow-oblong, at the base narrower 

 almost petioled, obtuse often with two points (as described by Harvey in Sujfrenia 

 capensis). Flowers not spicate, most minute. Calyx-tube short ; teeth 4, triangular, 

 accessory teeth 0. Petals if any minute, not yet seen. Stamens 2 (occasionally 3-4 

 Kurz:). Capsule spherical, slightly acute. Seeds black, half- ellipsoid or nearly half- 

 spherical, excavated on the plane face. Kurz says the capsule is 3-valved : the very 

 perfect examples from Chota Nagpore have the capsule 2 valved Suffrenia capensis, 

 Harvey Thes. Capens. ii. t. 189, differs from the Indian plant only in the larger and 

 longer capsule. Compare Rotala filiformis, Hiern in Oliv. Fl. Trop. Afr. ii. 468, 

 where Harvey's linear-leaved plant is united with the European Suffrenia which has 

 oblong, broad -based leaves.

 opposite narrow-oblong, flowers solitary axillary shortly pedicelled, capsule 3-

 calyx. Seeds black, subhemispheric, excavated on the plane face.
