36 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
7. Cyathocalyx, Champion. 
Trees. Leaves glabrous. Flowers fascicled, terminal or leaf-opposed. Sepals free or 
united into a B-lobed cup. Petals 6, 2-seriate, valvate in bud, sub-equal; bases concave, 
conniving; blade flat, spreading. Stamens indefinite, elongate, cuneate, truncate; anther- 
cells linear, dorsal. Ovaries solitary or 2—6, on a concave torus; stigma large, grooved, 
ovules many. Ripe carpels berried. Distrib.—Tropical India and Malaya; species 8. 
In its petals this genus resembles Artabotrys to some extent, but Polyalthia still more. 
The ovaries in the first two species are usually solitary; in the third they are three in 
number: the ripe carpels of all three being large, succulent and many-seeded. Baillon 
admits the genus as it was established by Champion and accepted by Hooker filius and 
Thomson. In the above diagnosis I have, however, modified the definition so as to 
provide for the species with more than one ovary. 
Ripe carpels ovoid. 
Ovaries solitary. 
Calyx remotely 3-toothed; carpels not grooved . . 1. C. seylanicus. 
Calyx acutely and deeply 3-lobed; carpels transversely

1, CyaTHocatyx zeEyLanicus, Champ.; H. f. & T. Fl. Ind. 127. A tree; young 
parts deciduously golden rufous-pubescent; the branches becoming glabrous and dark- 
coloured. Leaves coriaceous, narrowly eelliptic-oblong or oblong-lanceolate, shortly 
‘acuminate, the base cuneate; the under-surface at first minutely pubescent on the midrib 
and nerves; ultimately both surfaces glabrous, shining, minutely reticulate; main nerves 
9 to 12 pairs, thin, slightly prominent on the lower surface, oblique, inter-arching close 
to the edge ; length of blade 7 to 11 in., breadth 2°5 to 3°75 in.; petiole -4 in. Peduncles 
‘> to °75 im. long, extra-axillary, 1- or 2-flowered, ebracteolate. Calyx forming an 
obscurely 3-toothed truncate cup °2 in. deep, minutely rufous-pubescent externally. 
Petals thinly fleshy, oblong-lanceolate, sub-acute, yellowish-pubescent on both surfaces, 
1°25 to 15 in. long; torus of flower flat or concave. Pistil oblong, cylindric, with short 
style and broad discoid stigma. Fruit solitary, broadly oval, obtuse, glabrous, aromatic 
when fresh, nearly 3 in, long and about 1°75 in. in diam. Seeds 8 to 10, in two rows, 
compressed, smooth, but rugose at the sides. Thwaites’ Enum. 9; Bedd. Ic. Pl. Ind. Or.,
