958. (3) C. Missionis (Wall.:) fruit ellipsoidal, slightly compressed, not 
gibbous, furnished with 3 spines, winged ; spines elongated, lateral ones flat- 
tened; the wing broader downwards and decurrent along the base of the 
spines, with a few irregular teeth : sides of the fruit convex, finely tubercled.

This and the last do not appear to have been distinguished by the Mission- 
aries: at least the specimen sent by Klein to Willdenow belongs to the one, 
while those from his (or the Madras) herbarium before us have the fruit of 
the present species: except in the presence or absence of the wing there is, 
however, no difference, and we have merely separated them in deference to 
Chamisso's observations on the genus. Perhaps the whole three species 
ought to be combined as varieties under Roxburgh's name of C. verticillatum, 
characterized as a species by the ellipsoidal tubercled or muricated 3-spined 
not gibbous fruit. 
ORDER LIX.—RHIZOPHOREJE. R. Brown. 
Calyx 4—13-lobed : wstivation valvate, or sometimes calyptriform. 
Petals inserted on the ealyx, alternate with the lobes, and equal to 
them in number. Stamens inserted with the petals, twice or several 
times as many : filaments distinct : anthers erect, straight, or incurved. 
Ovarium adherent to the calyx, 2-celled, or 1-celled with a central co- 
lumella : ovules 2 in each cell, or several when 1-celled, pendulous. 
Fruit indehiscent, 1-celled. Seed pendulous, solitary. Albumen none. 
Radicle long: cotyledons flat.—Trees or shrubs. Leaves simple, op- 
posite, with stipules between the petioles. 
I. RHIZOPHORA. Linn. ; Gertn. fr. t. 45 ; Lam. ill. t. 396. 
Tube of the calyx obovate, coherent with the ovary; limb divided into : 
oblong persistent segments. Petals as many as the segments of the calyx, 
oblong, emarginate, coriaceous, conduplieate, and when young embracing the 
alternate stamens, the margins each with a double row of long woolly hairs. 
Stamens twice as many as the petals, alternating with them: anthers nearly 
sessile, large, linear-oblong. Ovary 2-celled, with 2 ovules in each cell. 
Style conical, short, 2-furrowed. Stigma 2-toothed. Fruit ovate or oblong; 
crowned near the base with the persistent segments of the calyx, longer than 
the tube, at length perforated at the apex by the radicle of the germinating 
embryo.—Trees, with quite entire leaves and axillary inflorescence.

HL KANDELIA.—Rhizophora $ Kandelia. DC. 
Tube of the calyx campanulate, coherent with the ovary ; limb divided 1n- 
to 5-6 linear persistent segments. Petals as many as the segments of the ca- 
lyx, membranaccous, linear at the base, cleft to below the middle into nume- 
rous capillary segments, glabrous. Stamens numerous, 6-8 times as many 45 
the petals; filaments subulate, as long as the calygine segments 5 anthers
