HuiLLA. — A resinous tree, 8 to 15 ft. high, not or scarcely milky ; 

 trunk erect, straight, 2 to 6 in. in diameter at the base branches and 

 branchlets somewhat tortuous, very rigid, patent, tuberculate and 

 transversely very rough with the soars of fallen leaves ; leaves 

 deciduous, alternate, digitately 5- to 7-foliolate, apparently exstipulate ; 

 leaflets articulated to the common petiole, coriaceous, shining, tomen- 

 tose beneath ; common petiole long ; flowers dioecious ; male flowers 

 usually appearing in the absence of the leaves ; female flowers solitary 

 in the axils of the leaves at the ends of the congested branchlets, veiy 

 shortly pedunculate ; peduncle included in an adnate sheath which is 

 tridentate at the apex down to the middle ; calyx 6- or 7- cleft, with 

 linear-subulate tomentose teeth ; disk annular ; ovary sessile, sur- 

 rounded at the base by the calyx-teeth, bilocular ; the cells bi-ovulate ; 

 the ovules pendulous geminately from the apex of the cell, anatropous ; 

 style simple, very short or obsolete ; stigma broadly bilobed ; the 

 lobes thick, stigmatose at the inner face ; epicarp bivalved ; pyrenes 

 long, enclosed in a somewhat fleshy mucous membrane ; seeds exal- 

 buminous ; testa (unripe) somewhat fleshy. In rather dry spots in the 

 less dense iEorests between LopoUo and the river Monino, sparingly, in 

 company with Combretace^, Mjrrtaceae, and Proteacese ; male and 

 female fl. and fr. towards the end of Feb. 1860. The specimens with 

 male flowers were plucked in great haste, for the tree on which they 

 grew was within the range of the storming hordes of the Munanoa 

 savages with whom war was being waged. No. 452, Coll. Carp. 955.
