OF THE DIPTEROCARPACEZ. 41 
inside. Petals longer than calyx-segments, puberulous outside. 
Stamens 20-35 ; anthers unequal valved, opening at the top, on 
short filaments; connective prolonged into a long awn. Stylo- 
podium thick, fleshy, sometimes hollow, constricted at base or 
bell-shaped, generally puberulous, bearing 3, sometimes 4-6 short 
glabrous styles, rarely one short trifid style. Ovary partly 
immersed in the broad, somewhat concave receptacle, the edges 
of which expand, as the fruit ripens, into a globose or campan- 
ulate calyx-tube, which is adnate to the entire fruit or to the 
greater portion of it. Two segments of fruiting-calyx much 
larger than the others, with 3 prominent longitudinal nerves and 
numerous transverse veins. Hypocotyl enclosed by the fleshy 
bifid or reniform cotyledons. 
In the circumference of the pith 18-24 resin-ducts, often large 
and close together. Three leaf-traces (one apical, two lateral) 
enter the petiole, the two lateral ones running in the bark, in some 
species through the entire internode, in others through the upper 
half of the internode only. The petiole under the insertion of the 
blade has a complete circle of 7-13 vascular bundles, which in 
some species are confluent, in others (Anisoptera Curtisii, Dyer) 
distinct ; a resin-duct in the pith of each vascular bundle. No 
resin-ducts, or only a few, in the central mass of vascular bundles. 
A well-defined genus, of which 15 species are known, 5 from 
the Eastern Peninsula of India, 3 from Borneo, 3 from the 
Philippine Islands, and 4 from New Guinea. A. Curtisii extends 
from the Malay Peninsula to Borneo.

112; Pierre, Fl. For. Cochinch. fasc. 15, t. 235 B. 
Evergreen forests on the east side of the Pegu Yoma and on 
the hills between rivers Sitang and Salween; Cambodia and 
Cochinchina. 
Glabrous; leaves coriaceous ; fruit 4 in. diam. ; fruiting-calyx 
tube much constricted at the mouth, the 2 larger segments 
oblanceolate, the 3 nerves equally prominent, joined by con- 
Spieuous transverse veins at right angle. 
At the British Museum are specimens from the State of 
Malacea (Mr. Ridley's collector, no. 841), in fruit, marked 
A. glabra, Kurz, by Dr. King, which fairly agree with Kurz's
