Doubtful species 



Trichilia Karwinskyana C. DC. in DC. Monog. Phan. 1: 663. 1878. Described from 

 a specimen collected by Karwinsky at Papantla, Mexico. The description reads very much 

 like T. albiflora C. DC. 



Trichilia parvifolia C. DC. is described from "Nueva Espafia (Pavon)." The specimen 

 probably came from South America. 



Trichilia scandens Lunan, Hort. Jam. 2 : 320. 1814. This is Stegm&perma halxmi- 

 folia Benth. (Portulacaceae).

fXylocarpus Konig, Naturf. 20: 2. 1784. 

 Persoonia Willd. Sp. PI. 2: 331. 1799. 



Tropical trees, mostly of coastal or riparian habitat. Leaves alternate, equally pinnate 

 or odd-pinnate. Leaflets entire. Flowers perfect, in terminal or axillary panicles. Calyx of 

 4 or 5 imbricate sepals or 4- or 5-lobed. Petals 4 or 5, free, reflexed, contorted, alternate with 

 the sepals. Staminal tube cup-shaped or ovoid, S- or 10-lobed, each lobe cleft or entire. Anthers 

 8 or 10, sessile within the tube at the base of the sinuses. Disk annular, fleshy. Ovary 4- or 

 5-celled, 4- or 5-grooved or -ribbed, sessile in the disk; style short; stigma disc-like. Ovules 

 biseriate, 4—8 in each cell. Fruit a large, 1-5-celled, subglobose or ovoid, woody or fleshy cap- 

 sule, the cells 2-5-seeded. Seeds large, angled, without endosperm; testa corky; cotyledons 

 thick, superposed, closely adherent; radicle lateral.
