Luzon, Benguet Subprovince, near Baguio, Merrill 9697, May, 

 1914. In shaded places about limestone bowlders, altitude about 

 1,400 meters. 



In vegetative characters this species somewhat resembles 

 Elatostema contiguum C. B. Rob., but differs remarkably in its 

 habit, being a much taller, strictly erect, branched plant, the 

 stems being decidedly woody. 



ELATOSTEMA SAMARENSE sp. nov. 



Herba succulenta, parce ramosa, usque ad 50 cm alta, in sicci- 

 tate pallide flavido-viridis, ramis parce ciliatis ; foliis chartaceis,. 

 leviter inaequilateralibus, oblanceolatis, 6 ad 11 cm longis, tenui- 

 ter acuminatis, margine perspicue serratis, supra cystolithis 

 numerosis instructis, scabris, foliis junioribus plus minusve 

 ciliatis; nervis utrinque 4 ad 6, supra impressis, subtus valde 

 perspicuis; stipulis anguste lanceolatis, circiter 1 cm longis; 

 inflorescentiis 9 axillaribus, sessilibus, solitariis, 5 ad 10 mm 

 diametro, bracteis connatis, lobis paucis, oblongis, 1.7 mm longis,. 

 ciliatis, bracteolis anguste oblongis, 2 mm longis; floribus 

 numerosis, acheniis oblongis, brunneis, cylindraceis, 0.8 mm 

 longis. 



An erect, sparingly branched, succulent herb, about 50 cm 

 high, pale greenish yellow when dry, the stem glabrous with 

 numerous cystoliths, the branches with scattered, spreading, elon- 

 gated, weak, white hairs. Leaves chartaceous when dry, some- 

 what inequilateral, oblanceolate, 6 to 11 cm long, 2 to 3 cm wide,^ 

 the apex slenderly acuminate, the base somewhat inequilateral, 

 acute on the narrower side, obtuse on the broader side, the mar- 

 gins rather conspicuously serrate except near the base, the upper 

 surface with numerous cystoliths, scabrous, the younger leaves 

 with numerous, spreading, elongated, weak hairs from swollen 

 bases, the swollen bases persisting on the older leaves causing 

 the surface to be distinctly scabrous, the lower surface of the 

 same color as the upper with equally distinct cystoliths, the 

 midrib and nerves with scattered, conspicuous, spreading, white 

 hairs ; lateral nerves 4 to 6 on each side of the midrib, impressed 

 on the upper surface, very prominent on the lower surface, 

 arched-anastomosing; stipules narrowly lanceolate, acuminate, 

 somewhat ciliate, about 1 cm long. Pistillate inflorescences ax- 

 illary, sessile, 5 to 10 mm in diameter, flattened, irregular, the 

 bracts connate, forming an irregularly lobed receptacle about 6 

 mm in diameter, the lobes rather few, oblong, 1.7 mm long, 

 ciliate; bracteoles very numerous, narrowly oblong, 2 mm long,
