A nJCriSlOX OF THE INDIAX SPECUuS OF ROT ALA. 717 



:i(l (14). Stom creeping, rooting, sending;- up many stout branches, jtm- 

 fusely flowering. Spikes lax, braetenlcs shorter than calyx. 

 Petals small, authors snbincluded. 

 ail (1 0-17) and (19). Kugged plants with more or less densely crowded 

 tlowors and generally la,ncoolaterellexed bracts. Stamens inserted 

 near base of calyx-tube. Petals small. Anthers an<l stigma 

 subiucluded. 

 ad (IS). A small erect plant. Spikes rather lax, about the length of 

 the leaves. Bracts small. Calyx broadly eampanulate. Style 

 about as long as the ovoid capsule, 

 ad ('20). Intermediate between forma a. and forma //. Stems several 

 from the root, profusely flowering. There is an abrupt change 

 from the largo leaves to the bracts proper. Ikacteoles as long as 

 the broadly eampanulate calyx. Anthers and stigma suboxserted. 

 Style only i as long as the capsule. Petals small, 

 ad (21). Stem creeping and rooting, long and stout, sending up 

 slender branches along its whole length. Leaves on stem up to 

 '20 X 10 ram. (the largest observed in this sijecies), broadly obovate. 

 Leaves on the branches gradually passing into bracts. Petals 

 minute. Stamens and style snbincluded. 

 ad (22). Erect or ascending, rooting at the base. Bracteoles hardly as 

 long as the calyx-tube. Petals small. Style shorter than capsule, 

 ad (23). Compact. Branches long, again divided. Bracteoles a.s long- 

 as the broadly eampanulate calyx. Petals minute. Stamens 

 included, 

 ad (24). A tall slender plant, 10 cm. high, with a poor rugged appear- 

 ance. Branches reaching 5 cm., almost horizontal. Flowers in 

 axillary clusters or very short spikes. Calyx long and narrow. 

 Bracteoles as long as the calyx-tube. Calyx-teeth ^ as long as 

 the tube. Anthers and stigma reaching tips of calyx-teeth. 

 Petals large, 

 ad (25). Creeping, tip of stem ascending, much branched. Petals 



very small, suborbicnlar. Style shorter than capsnle. 

 ad (26). Erect. Upper leaves subacute. Spikes short, adpressed, 

 dense. Flowers small, concealed by crowded adpressed bracts. 

 Bracteoles twice the length of the calyx, 

 ad (27). A slender weak plant, with broadly obovate leaves, short lax 

 spikes, large calyx, its teeth almost as long as the tube. Petals 

 minute . 



Stamens included. Style slightly exserted. 

 ad (28). Much-branched. Branches long, ascending, flexuose. Leaves 

 /^ovate-oblong, acute. Spikes lax ; bracts rather large. Calyx-tube 

 slender, teeth ^ its length. Petals as long as the calyx-teeth, 

 suborbicnlar. Stamens exserted. Style twice the length of the 

 capsule, far exserted. 

 ad (29). Not unlike forma c. but with much shorter spikes. 

 ad (30). An erect plant of very regular growth, tinged with pink. Stem 

 simple, except for the axillary spikes, which are shorter or longer 

 than the leaves. Calyx pink, narrow, teeth as long as tube ; 

 bracteoles longer than calyx. J'etals pink, .j length of calyx-teeth, 

 acute, 1-nerved. Stamens ami style subiucluded. 

 ad (31). Spikes not dense, reaching 4 cm. Bracteoles .\ the length of 

 the calyx. Calyx-teeth haif the length of the tube. Stamens 

 included, stigma exserted. 

 ad (32). Very unlike the other specimens from the Philippines under 

 forma //. and more similar to certain Burmese specimens.
