Throughout India ; very common. — Disteib. Cabul, Maecarene Islds., S.E. Asia, 

 Malaya, Australia to Fiji Isles. 



Stems loug, floating, rooting at the nodes. Leaves 2 -8 in. diam. ; petiole or 

 short. Pedicels 0-5 in., numerous, unequal. Calyx-lobes ^— J in., narrowly lanceolate, 

 CoroUor-lohes |-J in. Ovaury and stigmas nearly as in L. cristatmn. ■ Capsule |-| in., 

 subquadrate. Seeds ^ in., thickly lenticular, smooth or minutely glandular-puberu- 

 lous, never scabrous as in L. cristattim. — The descriptions of L. cHstatiim and 

 indicum by Grisebaeh are so incorrect, that Bentham quotes Thwaites as the primary 

 authority for this common species. Bot. Mag. t. 658, adduced here by Bentham, has 

 yellow flowers, and looks more like L. nympJueoides. 



4. Ii, aurantlacum, Dalz. in Hook. Kew Journ. ii. 136 ; leaves orbicular 

 deeply cordate, pedicels few from each node, corolla yellow lobes fimbriated on 

 the margin, capsule | in., seeds smooth. Dalz. 8^ Gibs. Bomb. Fl. 158. L.

Stems elongate, nodes not rooting. Lea/oes Ij in. diam. ; petiole often 1-3 in. 

 Pedicels commonly 2 from each node. Calyx-lobes 5, i by i in. Corollor-lobes ^ in., 

 sparingly fimbriate, without a longitudinal fold down the middle. Capside sub- 

 globose, 10-15-seeded. Seeds i in. diam.; nearly as of L. indicv/m; testa close, 

 thick, minutely reticulate, not papillose. 



5. Xi. Forbesianum, Griseb. Gentian. 345, and in DC. Prodr. ix. 139 ; 

 leaves small orbicular deeply cordate, peduncles numerous equalling or exceeding 

 the leaf, corolla white lobes 5 hairy within fimbriate on the margin, seeds 

 globose obtusely carinate most minutely punctate not muricate. 



Ce^xon; Macrae. 



Stems short ; pedicels many fasciculate ; corolla white {Macrae). — This appears to 

 be a small form of L. aju/rantiacum, but Macrae has twice noted the corolla to be 

 white. It is Menyanthes campestris, Macrae and Wight (in Herb.) partly ; but half 

 of Wight's sheet is L. Moonii, Thwaites. 



6. Xi. parvlfoUum, Griseb. in DC. Prodr. ix. 141; leaves small radical 

 spathulate-orbicular cauline deeply cordate, pedicels numerous fascicled, corolla
