Notes and Descriptions of Zingiberackar 



2901 



sheath finely striate, easily separating from the stem, dirty 

 puberulent, the thinner edges without hairs; ligule ovately 

 elongated, stiff, erect, 5 to 8 mm long, usually entire and 

 broadly rounded, densely yellowish pubescent on the back. 

 Inflorescence upon slender reddish stalks arising from the 

 horizontal rootstocks, spicate or occasionally branched; the 

 head triangularly elongated, 3 to 7 cm long, obovoid in 

 outline; peduncle somewhat shorter, appressed pubescent, 

 ultimately glabrous, imbricately provided with bracts; basal 

 bracts short and broadly ovate, increasingly becoming en- 

 larged toward the head, the upper ones 2.5 cm long by 1 

 cm wide at the clasping base and acuminate at the apex, 

 prominently striate, when old chartaceons and glabrate; outer 

 flowering bracts similar, erect, broadly lanceolate, with 

 sharply acuminate points, the sides inwardly folded, sparsely 

 hairy toward the base even in the fruiting state; inner 

 flowering bract 2 cm long, glabrous, the upper one third 2 

 to 3-lobed, the reddish ones sharply pointed and inwardly 

 folded; calyx a trifle longer, the upper one third 3-toothed, 

 the teeth similarly colored as the bract lobes, pubescent on 

 their backs and along the acuminate points; corolla tube 

 slender and a trifle longer than the calyx, puberulent; the 

 lobes oblong, submembranons, yellow below the middle, 

 otherwise reddish, the lateral ones shorter and narrower, 

 the upper one longest and 1.5 cm in length; lip 6 mm 

 long, folded over the stamen, apparently dark red, mi- 

 nutely punctate, ovately elongated, trnncately rounded at the 

 apex, glabrous as are the regular corolla lobes; fertile filament 

 very short though broad; anther 3 mm long; cells divergent 

 toward the apex which is notched and crestless, long hairy, 

 ventrally dehiscent, dull yellow; style slender and glabrate, 

 thickened toward the oblique and much enlarged stigma; cylindric 

 ovary more or less short hairy. Fruits subglobose, 1.25 era 

 in diameter, reddish brown, very short pedicel led, well 

 protected by the persistent bracts, densely covered with a 

 shining yellowish appressed pubescence, bearing the persistent 

 calyx, both ends truncately rounded and usually provided 

 with short blunt excrescences, otherwise smooth; seeds several 

 in each of the 3 cells, triquetrous, black and somewhat 

 grayish covered, 2.5 mm across.
