PHILIPPINE PLANTS, IX. 297 



COLUMBIA Pers. 

 COLUMBIA MACGREGORII sp. nov. 



Arbor, ramulis petiolis inflorescentiisque fulvo-ciliatis ; foliis 

 oblongis vel ovato-oblongis, acuminatis, basi rotundatis vel ob- 

 tusis, subaequilateralibus, 5-nerviis, margine irregulariter den- 

 ticulatis; paniculis terminalibus, bracteolis trifidis, circiter 8 

 mm longis, dense ciliatis; sepalis extus dense stellato-pubescen- 

 tibus, petalis, basi stellato-puberulis exceptis, glabris. 



A large tree, fide McGregor, the younger parts and the inflo- 

 rescence prominently f ulvous-ciliate. Leaves chartaceous, oblong 

 to oblong-ovate, shining, somewhat brownish when dry, of nearly 

 the same color on both surfaces or the lower one a little paler, 

 14 to 20 cm long, 4.5 to 7.5 cm wide, the base rounded or obtuse, 

 subequilateral, the apex acuminate, the margins irregularly den- 

 ticulate, upper surface with few, scattered, ciliate hairs, the lower 

 one very minutely stellate-puberulent ; basal nerves 5, the lateral 

 ones above the base about 7 on each side of the midrib, promi- 

 nent, ascending; petioles prominently f ulvous-ciliate, 1.5 to 2 

 cm long; stipules oblong, stellate-pubescent and ciliate, about 6 

 mm long. Panicles terminal, about 15 cm long, prominently 

 fulvous-ciliate with spreading hairs and also fulvous-stellate- 

 pubescent. Flowers numerous, yellowish with reddish spots, 

 about 1.5 cm in diameter. Sepals narrowly oblong or oblong- 

 lanceolate, about 8 mm long, 3 mm wide, narrowed to the acute 

 base and the acuminate apex, externally densely fulvous-stellate- 

 pubescent. Petals narrowly oblong-obovate or subspatulate, 6 

 to 7 mm long, 2.5 mm wide, the apex broadly rounded, narrowed 

 below, glabrous except the basal part, which is stellate pubescent, 

 and the slightly setose back, the basal gland about 1.5 mm in 

 diameter. Ovary subglobose, 2 mm in diameter, 5-sulcate, 5- 

 ridged, densely stellate-pubescent with fulvous hairs. Style 4 

 mm long, narrowed above and glabrous except near the base. 

 Bracteoles involucrate, 8 to 10 mm long, usually 3-cleft or 

 divided into three, lanceolate, acuminate lobes, their backs and 

 margins ciliate with 1 to 1.5 mm long fulvous hairs.

 April 12, 1912. 



A species distinguishable by its fulvous indumentum composed in part of 

 short stellate hairs and in part of long slender, ciliate ones. It belongs in 

 the group with the nearly equilateral leaves, allied to Columbia subaequalis 

 Planch., but differs from Planchon's species, as well as from the numerous 

 forms described by Warburg, in the character of its indumentum.
