casio, April 25, 1919, in thickets along streams at the iron de- 
posit.on the northeast coast. 
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. 
CALOPHYLLUM OLIGANTHUM sp. nov. § Apetalum. 
Arbor parva, glabra, ramulis tenuibus, teretibus; foliis oblongo- 
ellipticis ad oblongo-lanceolatis, coriaceis, 5 ad 10 cm longis, 
utrinque subaequaliter angustatis, basi cuneatis, apice distincte 
acuminatis; petiolo 8 ad 10 mm longo; inflorescentiis plerumque 
axillaribus, solitariis, pedunculatis, 2.5 ad 4 cm longis, floribus 
3 ad 5, racemosis vel umbellatis; sepalis interioribus elliptico- 
obovatis, circiter 6 mm longis, exterioribus late ovatis, 4 mm 
longis, apice rotundatis et perspicue cucullatis; fructibus ellip- 
soideis, 1.5 cm longis. 
A glabrous tree, 5 to 8 m high, the branches and branchlets

terminal, solitary, peduncled, 2.5 to 4 cm long, 3- to 5-flowered, 
the flowers either racemosely or- umbellately arranged, their ped- 
icels 1 to 1.5 cm long. Sepals white, the inner 2 elliptic-obovate, 
rounded, somewhat concave, about 6 mm long and 4 mm wide, 
the outer 2 broadly ovate, rounded, and conspicuously cucullate

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