but the veins not prominent and often very obscure, not above 2in. diameter in 

 some speciniens, above Sin. in others. Pedicels usually numerous in the clusters, 

 1 to 2in. long. Calyx-segments lanceolate, membranous, 3 to 4 lines long. 

 Corolla white, varying from 6 to 10 lines diameter, the margins fringed, the 

 inner surface more or less bearded at the base with pedicellate glands, but 

 without any longitudinal wing. Anthers linear-sagittate, on short flat filaments. 

 Style short or long, with two broad lobed and spreading stigmatic lamins. 

 Ovules on 2 broad parietal placentas. Seeds smooth tubercular or muricate. —

2. I., parvifolium (leaves small), Griseb. in DC. Prod. ix. 141 ; C. B. 

 Clarke in Hook. Fl. Brit. Ind. iv. 132. Stems long, floating, not rooting at the 

 nodes. Leaves small, radical spathulate-orbicular, ouneate at the base on the 

 broad petiole ; oauline deeply cordate, subsessile. Pedicels 3 to 10, at each node, 

 3 to 6 lines long. Calyx-lobes about f line long, oblong. Corolla white; lobes 

 5 — 4, fimbriate, about 2 lines long. Capsule oblong, narrowed below, about 2 

 lines long, 1 line broad. Seeds minutely puberulous. — -Clarke I.e. 



'V&x. Moonii. Flowers 4-merous. Capsule 2 lines long and broad, subglobose. Seeds smooth ; 

 testa thick, closely minutely reticulate. — L. Moonii, Thwaites, Enum. 206; Menyantkes cam- 

 pestris, Moon. Cat. PI. Ceyl. 13. 



Hab.: About Gainsford, E. Bowman (F. v. M. Fragm. ix. 163). The variety only as yet met 

 with in Australia. 



3. Ii. crenatum (leaves crenate), F. v. M. in Trans. Phil. Soc. Vict. i. 17, 

 and in Hook. Kew Journ. viii. 164 ; Benth. Fl. Austr. iv. 379. Stems floating 

 or creeping, emitting at the nodes tufts of leaves, or a single leaf and a cluster 

 of pedicels, or a short flowering-branch, as in L. geminatum, which this species 

 closely resembles. Leaves broadly orbicular-cordate or reniform, irregularly 

 crenate, 1 to Sin. diameter, usually thick. Pedicels 1 to 2in. long. Calyx-lobes 

 narrower and more acute than in L. geminatum and more united at the base. 

 Corolla yellow, above lin. diameter, the lobes fringed on the margin, bearded 

 inside at the base with a few long cilia, and bearing a prominent longitudinal 

 wing along their centre. Style conical, the stigmas erect, much dilated, the 

 margins reduplicate and deeply fringed, assuming the appearance of 4 longitudinal 

 wings to a conical stigma. Capsule membranous, 4 to 5 lines long. Seeds 

 smooth. — Villarsia crenata, F. v. M. Fragm. iv. 127.

4. Ii. geminatum (pedicels in pairs), Griseb. Gent. 846, and in DC. Prod. 

 ix. 140 {as to Broivn's plant) ; Benth. Fl. Austr. iv. 380. Stems floating in 

 water or creeping in mud, emitting at the nodes either a tuft of leaves without 

 flowers or a single leaf with a more or less elongated flowering branch, along 

 which the pedicels are in pairs or rarely 3 together with a pair of lanceolate 

 bracts at the base, but not paniculately branched as in Villarsia. Leaves broadly 

 ovate-orbicular or almost reniform, deeply cordate with a close or open sinus, 

 quite entire or very obscurely sinuate, digitately veined, rather thick, from under 

 1 to about 4in. diameter, but usuall rather small. Pedicels 1 to 2in. long. 

 Calyx-segments obtuse, much shorter than the corolla. Corolla yellow, J ^'^
