yellow at maturity, 13.5 em. long < 4.5 cm. in diameter, with 10 very 
blunt and rounded ribs, five rather more prominent than the others, 
with which they alternate. Larger ribs project about 10 mm. and have 
a width of 8 mm. at base. Small lateral or transverse ribs. All ribs 
carry large, scattered stellate hairs of white, shining colour. Pericarp 
has a thin, woody layer, elsewhere rather soft. Peduncle short (up to 
10 mm. in length <4 mm, in diameter, articulated at middle). 
It was my very good fortune to be able to see the 
Palmira trees in July 1958, when they were in extraor- 
dinarily profuse flower. One tree had more than 660 
flowers and buds in about thirty many-flowered inflores- 
cences scattered along the lower four feet of the trunk 
but concentrated near the base. The cacao agronomists 
at the Experiment Station inform me that the trees fruit 
heavily.
