In Congo lusitanico: »common in shady humid forests along the River Luali, 

 near the Official Residence at Belize, Mayumbe, fl. and young fr. Dec, (Gossweiler) 

 n. 7594«. — »A palm-shaped undershrub, unbranched and up to 3 m in height; flowers 

 appearing on the trunk.« »Leaves about 45 cm long; leaflets 9— 16 X 2,5 — 3 cm; 

 petiolules 2 — 5 mm long; inflorescences 12 — 14 cm long; pedicels 2 — 8 mm long; calyx- 

 lobes 3—4 x 2 — 3 mm; petals 3—4 X 1,5 — 2 mm; young fruits 12 — 14 X 5 — 8 mm«. 



»This species is allied to Ch. stenophyllus Gilg and Ch. Laurentii De Wild., both. 

 from the Belgian Congo. It differs from the former by the extremely minute pubescence 

 beneath the leaves, those of Ch. stenophyllus being described as laxly pilose on the 

 nerves. Moreover, the leaves are 9- or perhaps 10-jugate in the Gossweiler specimens, 

 while in Ch. stenophyllus the leaves are described as 4— 5-jugate. Ch. Laurentii De 

 Wild, has axillary racemes arising from the axils of leaves, which have not yet fallen 

 off, and not from the trunk, as in Ch. angustifolius.«
