Rob. Its staminate bracts are not cornicnlate. Leaves thick- 

 er in texture, midrib and nerves beneath more conspicuous 

 and distinctly umbrinus in color, shorter and relatively nar- 

 rower, with cystoliths more prominent on th" upper surface 

 and whose stipules are twice as long as in Dr. Robinson's 

 species. 



Elatostema urdanetense Elm. n. sp. 



Small scattered terrestrial tufts; stems 1.5 to 2 cm 

 long, rather slender, usually only a few from the same 

 root cluster, reclining at the base and bearing fibrous 

 roots along the under side, dirty strigose toward the top, 

 rather slender, very seldom branched, leaf bearing from 

 above the middle toward the upper end. Leaves alterna- 

 ting, ascending or horizontal, the terminal ones largest, flat, 

 coriaceous, glabrate on both sides, cystoliths more pronounc- 

 ed and whiter on the upper surface, very dark green 

 above and very light green beneath even in the dry state, 

 oblongish to obovate or subcuneately oblong, inequilateral, 

 straight along the upper edge of the narrower side, broadly 

 cuneate toward the obliquely obtuse base, 3.25 to 4 cm 

 long, 1.5 cm wide across the middle or just above this, 

 apex bluntly acute or merely toothed, entire except the 

 crenately toothed edge from the middle to the apex or 

 the wider lower side and only 2-toothed along the upper 

 edge toward the apex, sessile, the basal leaves frequently 

 much reduced; the midrib umber brown and occasionally 

 strigose beneath in the dry state, extending nearly straight 

 into the apex; the basal lateral pair of nerves arising from 

 near the base but not opposite, extending along the margin 

 a few mm below the edge of the lamina, their tips coarse- 

 ly anastomosing with the 1 to 3 pairs of secondary nerves 

 arising from the midrib above the middle, other reticula- 

 tions very few, all similar in color and vestiture to the 

 more prominent midrib; stipule subhyaline, oblongish, 

 about 5 mm long, early or easily falling. Inflorescence 

 upon ascending slender stalks, odorless, greenish except the 

 watery white flowers, solitary in the upper leaf axik; pis- 

 tillate not seen; peduncle 3 cm long, greenish and with mi-
