inaequalibus, oblongis ad oblongo-ovatis, usque ad 8 cm longis, 
in siccitate saepe nigrescentibus, acutis, basi obtusis ad subacutis, 
nervis utrinque 10 ad 14, distinctis; stipulis bifidis, lobis filifor- 
mibus, pubescentibus, 4 ad 6 mm longis ; cymis pedunculatis, sub 
anthesis circiter 1.5 cm diametro, perspicue pubescentibus; flo- 
ribus circiter 6.5 mm longis, corollae tubo dense pubescente; 
capsulis compressis, subflabelliformibus, circiter 4 mm longis et 
7 mm latis, pubescentibus, apice rotundatis vel subtruncatis. 
An erect, simple or sparingly branched herb, 5 to 12 cm high, 
most parts distinctly pubescent or puberulent, the stems mostly 
3 to 6 cm long, somewhat woody below. Leaves of each pair 
distinctly unequal in size, in general oblong to oblong-ovate, 3 to 
8 cm long, 1.5 to 3.5 cm wide, often black when dry, apex acute, 
base acute to rounded or obtuse, both surfaces more or less 
pubescent or puberulent, especially on the midrib and nerves; 
lateral nerves 10 to 14 on each side of the midrib, distinct, 
curved, anastomosing ; stipules cleft into two filiform, pubescent, 
4 to 6 mm long lobes; petioles 5 to 12 mm long, pubescent. 
Cymes peduncled, rather dense, about 1.5 cm in diameter in an- 
thesis, all parts including the corolla densely pubescent. 
Flowers white, about 6.5 mm long, the pedicels short. Calyx 
ovoid, pubescent, 2 mm long, the teeth 5, 0.5 mm long. Corolla- 
tube densely pubescent, 3.5 mm long, the lobes oblong, obtuse, 
about 2 mm long. Capsules pubescent, compressed, about 7 mm 
wide and 4 mm long, subflabelliform, apex rounded to subtrun- 
cate, not lobed. 
Luzon, Rizal Province, Mount Susong Dalaga, Bur. Sci. 29353

titude at least 1,000 meters. 
This species somewhat resembles Ophiorrhiza macgregorii 
Merr., but is not closely allied to it. It is strongly characterized 
by its pubescent flowers and its pubescent, somewhat fan-shaped 
capsules which are compressed but not at all lobed, and rounded 
or truncate at their apices. 
OPHIORRHIZA STENOPHYLLA sp. nov. 
Herba erecta, simplex, 7 ad 13 cm alta, eaulibus dense cinereo- 
vel griseo-pubescentibus ; foliis lanceolatis ad anguste lanceolatis, 
chartaceis, in paribus distincte inaequalibus, supra olivaceis, 
glabris vel subglabris, subtus pallidioribus, ad costa nervisque 
minutissime puberulis, 3 ad 7 cm longis, 0.5 ad 1.3 cm latis, 
utrinque angustatis, acuminatis, nervis utrinque circiter 10, te- 
nuibus ; inflorescentiis cymosis, paucifloris, tenuiter pedunculatis ; 
floribus circiter 5 mm longis, corollae tubo glabro.
