XIV. 4 Merrill: Noteworthy Philippine Plants, XV 425 



13 cm longis, basi rotundatis, leviter cordatis, apice tenuiter 

 caudato-acuminatis, margine irregnlariter dentatis ; petiolo 15 cm 

 longo; inflorescentiis foliis subaequantibus, paucifloris; floribus 

 S circiter 3 cm diametro. 



An entirely glabrous herb, the rhizomes creeping, simple, 

 about 5 mm in diameter, supplied with numerous, lanceolate, 

 caudate-acuminate, brown stipules, 1 to 1.5 cm in length. Leaves 

 pale-green on both surfaces when fresh, when dry membrana- 

 ceous, somewhat shiny, oblong to oblong-lanceolate, nearly equi- 

 lateral, 7 to 13 cm long, 2.5 to 4 cm wide, base rounded and very 

 slightly cordate, narrowed upward from the lower one-third to 

 the slenderly caudate-acuminate apex, the margin irregularly 

 toothed, a few of the teeth rather large, most of them small; 

 basal nerves about 8 ascending, a few lateral nerves leaving the 

 midrib at and above the middle; petioles about 15 cm long. Pe- 

 duncles of the staminate inflorescences 19 to 24 cm long, usually 

 with 2 short branches at the apex, each bearing about 2 rela- 

 tively large white flowers about 3 cm in diameter. Sepals 2, 

 oblong-elliptic rounded, about 1.8 mm long, 10 mm wide. Petals 

 narrowly oblong, equaling the sepals, 3 to 3.5 mm wide, rounded. 

 Stamens about 35, the anthers oblong, about 1.5 mm long; fila- 

 ments about 1 to 2 mm long. 



Panay, Antique Province, Culasi, Bur. Sci. 32232 (type),

 elopes, altitude 900 to 1,000 meters. 



This species is not closely allied to any previously described 

 Philippine form and is very strongly characterized by being en- 

 tirely glabrous ; by its nearly equilateral, oblong-lanceolate to lan- 

 ceolate, caudate-acuminate leaves which are slightly cordate at 

 the base ; by its long peduncles ; and its few, comparatively large, 

 white flowers. 



BEGONIA OBTUSI FOLIA sp. nov. § Diploclinhim. 



Herba prostrata, petiolis et subtus foliis ad nervis adpresse 

 ferrugineo-pubescentibus ; foliis longe petiolatis, oblongis, inae- 

 quilateralibus, 7 ad 10 cm longis, apice obtuse rotundatis, basi 

 leviter oblique cordatis, margine late lobatis vel undulatis, lobis 

 rotundatis; inflorescentiis quam foliis longioribus, paucifloris; 

 floribus s circiter 3 cm diametro; capsulis aequaliter 3-alatis, 

 junioribus circiter 14 mm latis et 10 mm longis, apice subtrun- 

 catis, basi rotundatis. 



Rhizomes slender, creeping, the petioles and nerves on the 

 lower surface of the leaves appressed ferruginous-pubescent.
