multifloris, floribus 5-meris; fructibus parcissime hirsutis vel 

 vetustioribus glabris, apiculo centrico. 



A tree 10 to 20 m high, the growing tips of the branchlets 

 rather densely appressed ferruginous-hirsute. Branches terete, 

 brown, giabrous. Leaves oblong, coriaceous, somewhat shining, 

 20 to 35 cm long, 8 to 12 cm wide, pale or brownish-olivaceous 

 when dry, of about the same color on both surfaces, the apex 

 shortly, abruptly, and obtusely acuminate, base narrowed in the 

 lower one-fourth, cuneate or somewhat decurrent-acuminate ; 

 primary nerves 17 to 22 on each side of the midrib, prominent, 

 the secondary nerves and reticulations netted, not parallel, dis- 

 tinct; petioles 1 to 2 cm long. Panicles numerous, in the upper 

 axils, usually about 20 cm long, many-flowered, all parts with 

 few, scattered, usually appressed, pale or ferruginous, hirsute 

 hairs, in fruit sometimes becoming nearly or quite glabrous. 

 Flowers 5-merous, white, the pedicels 1 mm long or less. Calyx- 

 lobes oblong, obtuse, about 1 mm long. Petals oblong, obtuse, 

 about 2.6 mm long, 1 mm wide, reflexed. Disk glabrous. Fila- 

 ments about 1.3 mm long, much narrowed at the apex; anthers 

 about 1 mm long, prominently sagittate. Carpels rather densely 

 pubescent. Mature fruits red, orbicular to broadly obovoid, 

 somewhat compressed, about 1 cm long, the apiculus central, 

 when immature with few, scattered, pale or ferruginous hairs, 

 in age glabrous or with very few hairs. 



This species is widely distributed in the Philippines and is manifestly 

 allied to the commoM Buchanania ar^borescens Blume, differing notably in 

 its much larger, more numerously nerved leaves. The type is For. Bur. 

 S027Jt Miranda, from the Province of Misamis, Mindanao, March, 1913, 

 and I refer here also the following specimens: 



Luzon, Province of Cagayan, For. Bur. 1715U, 17 SOS Curran, For. Bur.

 Bur. 220S2 Sherfesee, Cenabre, & Ponce. It is known in Cagayan Prov- 

 ince, Luzon, as paleng, arangas, sambrit, and pappagan; in Mindanao as 

 manguian; and in Basilan as lingdbunu.
