226 LEAFLETS. 



acumination, commonly with a few coarse teeth, often with a 

 prominent lobe on one side at the base, texture very firm, 

 both faces minutely and thinly appressed-pubescent ; leaves 

 of fertile branches quite similar, but with only 3 to 5 leaflets 

 and surpassed by the cymes of smallish white flowers : sepals 

 of pistillate flowers 5 or 6, spatulate-obovate to oblanceolate, 

 reflexed and rather persistent, softly silky : stamens of such 

 pistillate flowers 5 to 10, with flattened filaments either linear 

 or slightly lanceolate-dilated, anthers manifest, but perhaps 

 effete ; staminate plant unknown : achenes silky-plumose to 

 above the middle, nearly naked for some distance below the 

 apex. 



Species known only as collected by myself in the half desert 

 hills near Golconda, in northwestern Nevada, 27 July, 1896. 



POLYCODIUM OLiGANTHUM. Shrub apparently low, the 

 branches short, slender, widely spreading, or some recurved, 

 thinly hirsutulous with whitish hairs, some spreading, others 

 turned upward : leaves subcoriaceous, small, the largest only 

 1 inch long, oval, acutish, glaucous beneath, scarcely glau- 

 cescent above, also with scattered hairs near the margin and 

 on the very short petioles : flowers scattered singly in the 

 axils of the ordinary foliage : corolla rather ample and deeply 

 lobed : stamens short : fruit small, globose, conspicuously 

 crowned by the triangularly lobed calyx. 



Known only as collected at Lemon Bay, Florida, 23 May, 

 1906, by S. M. Tracy ; his n. 7264. A fine new member of 

 that Floridan group that has no distinct and separate inflor- 

 escence. 



PoLYCODiuM Langloisii. Branches slender, minutely and 

 sparsely pubescent with short curved hairs, the pubescence 

 permanent, at least during several seasons : leaves ample, 

 thin, deep-green and almost alike as to color on both faces, 

 pubescent along the veins on both faces, of oval-elliptic out- 

 line, IVt. to 3/^ inches long, 1>4 to \Y\ inches wide, subses-
