 August 21, 1915, on slopes in thickets or forests. 



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.

 July 29, 1915, in forests on the lower slopes. 



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.
