3072 Leaflets of Philippine Botany [Vol. viii, Art. 121 



upon a pseudostalk, at least 1 cm. long and nearly as 

 broad across the 5-apiculate otherwise truncate apex. 

 Fruit 16 cm. long by 1.5 cm. thick, subterete, blunt at 

 the base, sharply pointed, rigid, glabrous, dull green 

 but dirty brown when dry, longitudinally dehiscent and 

 divided by a thin or membranous portion; seeds numerously 

 packed in each half, the coma portion toward the distal 

 end; achene imbricately overlapping, dull brown, nearly 

 2 cm. long, lanceolate, striate, somewhat compressed above 

 the pointed base; coma silky, about twice as long, profuse 

 and persistent, radially spreading, white except at the 

 brownish base. 



Type specimen number 17867, A. D. E. Elmer, Los 

 BatLos (Mt. Maquiling), Province of Laguna, Luzon, June- 

 July, 1917. Gathered in dry jungled woods at low altitude 

 among the grass covered hills. 



Probably the same as Parsonsia conficsa Merr. but our 

 much larger leaves are ovate in shape rather than elliptic. 



ARACEAE 



Rhaphidophora lagunensis Elm. n. sp. 



A small tree climber and forming tangled masses. 

 Branchlets glabrous, terete, 1.25 cm. thick, prominently 

 and rather closely ringed, succulent at the green tips, 

 often with slender streamers. Leaves numerous, arranged 

 in 2 alternating rows, crowded terminally, glabrous, thickly 

 coriaceous, diverse in size, usually much smaller ones 

 at the base of the same branch or upon the shoots or 

 streamers; petiole much ascending, up to 6 cm. long, 

 caniculate along the upper side, expanding and clasping 

 at the base, rather stout, the edges of the canal often 

 winged; blades up to 15 cm. long and nearly one half 

 as wide below the middle, usually smaller, ovate, acute, 

 broadly obtuse or rounded at the base, descending from 

 the end of the petiole, lucid and much darker green 

 above, folded, entire; midrib pronounced, the very tine 

 and numerous lateral nerves ascending. Peduncle soli- 

 tary or few, terminally clustered, 10 cm. long, thick, 

 ascending, terete, glabrous; spikes erect, equalling the 

 peduncles, terete, glaucous green, 2 cm. thick; spathe 

 very thick, abruptly but sharply pointed at the apex, 

 sides tightly overlapping, rigid and very thick, green 

 on the outside, yellowish on the inner surface; drupes 

 forming a solid cob, the flat apex stoutly rimed and 

 sunken, the middle with a blunt stigraatic point, angular, 5 

 to 8 mm. long or longer; seeds several near the base,
