Stem 15-30 cm. long, 4-gonous, creeping and rooting. Leaves opposite, the 

 cauline 7-10 mm. long, about 3-4 mm. broad, sessile, elliptic-oblong, rounded 

 :it the apex, not conspicuously nerved. 



Flowers solitary, axillary, pedicels up to 1 mm. long, bracteoles minute, 

 subulate. Calyx about 2 mm. long, subtubular-campanulate, 4-gonou8, at 

 last narrowly cyathiform and terete, teeth 4, minute, the accessory teeth 

 rather larger than the primary ones. Petals 4, minute, scarcely 1 mm. long, 

 (ivate or obovate, pale rose coloured. Stamens 4, inserted a little below the 

 middle of the tube, reaching about % the length of the tube. Ovary narrow- 

 ly ellipsoid, style scarcely longer than the broadly capitate stigma, as long 

 as the anther. 



Capsule 4-valved, ellipsoid, included in the calyx. Seeds elliptic, peltate, 

 brown-yellow. 



Habitat : Bombay Presidency : Belgaum, in rice fields, rooting amongst 

 floating weeds, rare (Ritchie 1184).

Stems 16-53 cm. long, scarcely winged. Leaves 7-26 mm. long, 2-5 

 mm. broad, exstipulate, the lower ones sometimes linear, scarcely cordate, 

 the upper cordate and often dilated at the base, lanceolate or oblong, 

 obtuse. 



Flowers 4-5-6-merous. Bracteoles very short, ovate, acute, slightly 

 falcate, or half as long as the calyx, subulate. Calyx 2-2*5 mm, long, broadly 

 oampanulate. Petals large, deeply fimbriate-incised. Stamens 4-5-6, 

 exserted. Filaments inserted near the base of the calyx-tube. Style 1-2 

 times as long as the ovary. 



Capsule 3-valved, elongate-ellipsoid, large, scarious. 



Habitat : W. India : Badami, Sept. 1911 (Bhide ! ), Sanvardem, Goa, 

 Oct, 1908 (Meebold, No. 10282 ! ) ; Mysore in paddy fields or on borders of 

 tanks (Wight, No. 975 !). Without locality (Wallich, No. 2104 ! ).

Stems 20-35 cm. long or more, rooting below, very stout, sharply 

 quadrangular, almost winged. Leaves 6-25 mm. long, 2-5 mm. broad, 

 auriculate-cordate, amplectent, broadly linear, lanceolate, or oblong, obtuse 

 or subemargiuate. Stipules herbaceous, subulate, 2 mm. long, situated on 

 the sharp corners of the stem, 



Bracteoles deltoid-acute, scarious, slightly falcate, 1 mm. long or less, 

 llowers 5-6-merous. Calyx 2 mm. long, very broadly companulate-subhe- 

 mispheric. Teeth about ^ the length of the tube, deltoid-acute. Cornua 0. 

 Petals about as long the calyx-teeth, rhomboid or obovate, erose-denticu- 

 late. St^'le as long as the ovar}^ 



Capsule 4-(perhaps also 2-) valved, scarious, globose. 



Habitat: Ava: near Segaen (Wallich, No. 2103!): Arracan : Kolodync 

 valley, wet pastures and swamps, frequent, Oct. 1869 (S. Kurz!). 



Note. — In Wallich's specimen the flowers are 6-merous and the stamens 

 far exserted, whilst Kurz's plant has 5-merous flowers with the stamens 

 subexserted. This is the reason why we had to make a new species which 

 includes both plants.
