546 cix. ACANTHACE^. (C. B. Clarke.) [Rungia. 



similar to the bracts or narrow. Calyx smalU deeply 5-lobed ; segments 

 linear-lanceolate. Corolla small, blneish or white ; limb 2-lipped, upper lip 

 emarginate shorter than the lower 3-lobed lip. Stamens 2 ; anthers 2- 

 ceUed, cells parallel subeqnal, or more often superposed, lower cell mnticons 

 or white-tailed. Ovary 4-ovulate ; style filiform, minutely bifid. Capsule 

 ovoid or oblong, shortly stalked; after dehiscence the placent» with 'the 

 retinacula rise elastically from the base of the capsiile, scattering the 

 seeds. Seeds. 4, , compressed, orbicular, glabrous, verrucose, sometimes 

 minutely, sometimes very strongly, so that the seed is concentrically rugose 

 or suberistate. — Species 20, mostly Asiatic, a few Tropical African. 



I am unable to make sections of this gen.as ; the species are described in order of 

 their size, beginniug with the largest.

 smaller flowering ones on the other ; empty bracts a by ^ in., narrowed at both ends, 

 shining green, not or very narrowly manginate, striate ; flowering bracts similar but

 somewhat laxly imbricate, often panicled ; empty bracts ^ in. diam., obtuse rarely 

 minutely apiculate ; flowering bracts rather narrower, somewhat obovate ; bracteoles

 bracts sub-4-scriate, all fertile, f by J in., narrowed at base; margin prominent, 

 scarious, purplish ; bracteoles \ in., linear, glabrous. Calyx ^ in. ; segments linear-
