Bur. Sci. 35720 (type), 35392, 35535, 35588, 35676 Martelino

In general this species resembles, and is manifesty allied to, 
Trichosporum truncatum Elm. and T. bakeri Merr.; but the 
calyx is half as long as in the latter, while it differs from the 
former in several characters.

TIMONIUS ROTUNDUS sp. nov. 
Arbor glabra, circiter 5 m alta; foliis crasse coriaceis, late 
elliptico-ovatis, nitidis, apice late rotundatis, basi subtruncatis 
ad acutis, nervis utrinque 4 vel 5, valde perspicuis; infructes- 
centiis axillaribus, pendunculatis, usque ad 10 cm longis, dicho- 
tome ramosis, ramis primariis usque ad 7 cm longis; fructibus 
sessilibus, depresso-globosis, glabris, 5 ad 8 mm diametro. 
A small glabrous tree, about 5 m high, the branchlets about 
6 mm in diameter, marked with large petiolar scars. Leaves 
thickly coriaceous, broadly elliptic-ovate, brownish-olivaceous 
and shining when dry, the apex broadly rounded, base subtrun- 
cate to acute; lateral nerves 4.or 5 on each side of the midrib, 
very prominent, the reticulations fine, dense; petioles about 4 cm 
long ; stipules oblong-elliptic, rounded, about 2 cm long, deciduous. 
Infructescences axillary, peduncled, up to 10 cm long, dichoto- 
mously branched, the peduncles about 3 cm long, the primary 
branches up to 7 cm in length, the secondary ones when present 
shorter. Fruits sessile, arranged on one side of the primary or

A species apparently belonging in the group with Timonius 
obovatus Elm. but with very differently shaped, much larger 
leaves.
