casio, April 25, 1919, in thickets along streams at the iron de-

Although the flowers of this species are as yet unknown, it 
seems to belong in the group with Calophyllum soulattri Burm. 
f. ( C . spectabile Willd.) ; it is well characterized by its leaves 
being broadly rounded and conspicuously cucullate at the base.

acuminatis; petiolo 8 ad 10 mm longo; inflorescentiis plerumque 
axillaribus, solitariis, pedunculatis, 2.5 ad 4 cm longis, floribus

the flowers either racemosely or umbellately arranged, their ped- 
icels 1 to 1.5 cm long. Sepals white, the inner 2 elliptic-obovate,

This species very closely resembles Calophyllum gracilipes 
Merr. but the petals are lacking, and it further differs from this
