March 27, 1915] Two Hundred Twenty Six New Spkcirs— II 2849 



Elatostema camiguinense Elm. n. sp. 



Dense masses scattered in clumps; stems exceedingly 

 variable in length, from 3 cm to 5 dm high, angular, at 

 the base reclining, only the larger ones branched from the 

 middle, more or less reclining at the base or creeping and 

 profusely rooted, erect or nearly so, pseudostrigose, green 

 when dry; runners arising from the lower leaf axils or from 

 the root portion of the stem, horizontal, 1 dm long or 

 longer or shorter, very slender. Leaves alternate, chiefly 

 above the middle, paler green beneath both in the fresh 

 and dry state, thinly coriaceous, subsessile, the widely scat- 

 tering lower ones much reduced, the larger lamina 9 cm 

 long by 2 cm wide across the middle or the widest por- 

 tion, the narrower ones broadly lanceolate, otherwise elonga- 

 ted, inequilateral and subfalcate, similarly tapering toward 

 both ends, cuueate toward the oblique base, apex slenderly 

 acuminate, the basal one third to one half entire, otherwise 

 coarsely and sharply serrately dentate, glabrous, cystoliths 

 obscure beneath, the leaflets on the runner obliquely obovate 

 and about 5 to 8 mm long, occasionally more elongated; 

 midrib gradually curved, similarly green beneath, not con- 

 spicuous; the lower or wider side with 3 to 4 nerves, 1 to 

 2 nerves less in the upper or narrower side, the basal one 

 extending along the edge and about one half the length of 

 the blade, the upper basal nerve extending along the edge 

 to above the middle of the blades; the balance ascendingly 

 curved from the middle or above the middle, usually forked 

 toward their distal ends and terminating into the teeth, 

 other cross bars and reticulations none; stipular bracts linear 

 and setaceously pointed, pale yellowish green, glabrous, 5 

 mm long or shorter, subpersistent, pistillate flowers in ses- 

 sile clusters from the upper leaf axils; staminate ones pedicel- 

 led and usuaily from the lower leaf axils or along the basal 

 portion of the stem or even upon the runners; peduncle 

 varying from 5 to 20 mm long, glabrous, pale green; in- 

 volucre broadly cup shaped, green, usually composed of 2 

 unequal pairs of alternating bracts; outer and larger pair 

 connate at the base, 5 mm long, elliptic though apex some-
