This species is well characterized by its 5-plinerved, entire, shining leaves 
and its ferruginous inflorescence. It seems to be very closely allied to 
Naravelia antonii Elm., but my specimen of that species is entirely glabrous. 
ANONACEAE 
PHAEANTHUS Hooker f. & Thomson 
PHAEANTHUS NITIDUS sp. nov. 
Arbor, partibus junioribus inflorescentiis foliisque plus mi- 
nusve pubescentibus ; foliis oblongis, chartaceis, usque ad 16 cm 
longis, tenuiter acute acuminatis, basi acutis, nervis utrinque 11 
ad 13, prominentibus, in siccitate uniformiter castaneis, nitidis; 
floribus longe pedicellatis, petalis interioribus oblongis, obtuse 
acuminatis, circiter 2.5 cm longis; ovulis solitariis. 
A tree, the branchlets and inflorescence distinctly ferruginous- 
pubescent, the branches and branchlets slender, terete. Leaves 
castaneous when dry, shining, oblong, chartaceous, 12 to 16 cm 
long, 4.5 to 6 cm wide, the upper surface with scattered fer- 
ruginous hairs, ultimately glabrous or nearly so, the lower sur- 
face of about the same color, ferruginous-pubescent on the midrib 
and lateral nerves; lateral nerves 11 to 13 on each side of the 
midrib, prominent, gradually curved; petioles pubescent 3 to 
5 mm long. Inflorescence extra-axillary, each with but one or 
two yellowish flowers at a time, peduncled, more or less corym- 
bose, ferruginous-pubescent. Pedicels slightly pubescent, about 
3 cm long. Sepals very minute, less than 0.5 mm long. Outer 
three petals triangular-ovate, acute, somewhat pubescent, less 
than 1 mm long. Inner three petals oblong, coriaceous, about 
2.5 cm long and 1 cm wide at maturity, outside sparingly pubes- 
cent, especially at the base, inside glabrous, nearly black when 
dry, somewhat excavated at the base inside. Stamens very 
numerous, about 2 mm long, the connectives obliquely truncate. 
Carpels numerous, pubescent, gibbous, with the styles 3.5 to 4 
mm long; ovules solitary.

This species is manifestly allied Phaeanthus ebracteolatus (Presl) Merr. 
(P. cumingii Miq.), from which it is readily distinguished by its leaves 
being uniformly castaneous when dry, its ferruginous indumentum, and 
its more numerously nerved, long, and sharply acuminate leaves. Ap- 
parently referable here is Bur. Sci. 20922 Ramos, from Mount Isarog, 
Province of Camarines, Luzon, distributed as Phaeanthus ebracteolatus 
Merr.
