and the umbel of fl. but no roots nor any branch ; 1, of two 

 kinds, radical ones forming a rosette, about \ in., spathulate 

 or deltoid, obtuse, on long broad petioles, and floating ones 

 \-\ in., broadly oval, deeply cordate with oblong lobes and a 

 widely triangular sinus, with petiole \-\ in., cor. small, about 

 \ in. diam., lobes 4, oblong, subacute, fimbriate, slightly pilose; 

 capsule globose, apiculate; seeds 15 or more, finely muri- 

 culate. 



In ponds or on wet ground in the moist low country ; rare. Kalutara ; 

 Weligama; Colombo. P"l. Sept.-December; white. 



Also in S. India and Burma. 



Our plant varies greatly in size and appearance, according to the 

 growth on land or in water. Moon's are terrestrial, hence his name, 

 campestris J but I cannot see any distinct variety as given in Fl. B. Ind.

Rhizome elongated, branches few, very long, not petiole- 

 like but with several nodes producing 1. and fl. ; 1, obviously 

 alt, 14-2 in., oval-rotundate, deeply cordate with subacute 

 lobes and a narrow sinus, rounded at apex, purple and dotted 

 with black glands beneath, petiole longer than 1. (of the 

 radical 1. 4-6 in.), dilated and stem-clasping at base ; fl. few, 

 1-3, opp. the 1. at the nodes, with an oblong bract beneath; 

 cal.-segm. acute ; cor. nearly \ in. diam., lobes 5, fimbriate ; 

 capsule globose ; seeds about 20, rather large, globose, very 

 finely pubescent. 



Moist low country; very rare. Only about Kalutara and other parts 

 of Pasdun Korale, where it was first noticed by Moon. Fl. Sept.-Dec; 

 yellow. 



Also in S. India. 



The stems, petioles, and ped. are usually purplish-red. 



[Z. Forbesiafium, Griseb. in DC. Prod. xi. 139, is partly based on 

 specimens from Macrae from Kalutara, and the species is maintained in 

 Fl. B. Ind. The specimens (Macrae, Nos. 86 and 87) are in Herb. Kew, 

 and appear to be precisely L. ai(7-aniiacum ; and Macrae's note that the 

 fl. are * white ' is, doubtless, an error of observation.]
