oblong or globose ; ovules 5 or fewer, in one series. Fruit-carpels slipitate, 

 1-3 -seeded. 



Climbing shrubs, with membranous or rather coriaceous leaves ; the venation more or 

 less transversely parallel. Flowers very small, axillary, on simple forked or paniculate 

 peduncles or from the old wood. 



Notwithstanding the important differences between the two following species, I feel but 

 little hesitation in referring them to the sauie genus. To adopt ihe alternative of creating 

 a new genus for C. Mannii, with our present imperfect knowledge of the family, would be 

 premature. 

 Mowers hermaphrodite. Inner petals nearly equalling the outer. Anthers 



dilated behind the cells . I. C. Vogelii. 



Flowers unisexual. Inner petals minute. Anthers not dilated behind the 



cells 2. C. Mannii. 



1. C. Vogelii, Planch.; Benth. in Linn. Traits, xxiii. 479. A climb- 

 ing shrub, with slender branchlets, minutely rusty-sericeous at first or gla- 

 brous. Leaves thinly coriaceous, obovate- or elliptical-oblong, shortly acu- 

 minate or obtuse, glabrescent, glaucescent or reddish -glaucescent beneath, 

 3-6 in. long, 1-2 in. broad ; petiole 1-^ lines. Flowers very small, on 

 slender axillary pedicels, -^-l in. long, at first with a minute bracteole near 

 the middle. Sepals ovate-rotundate, sliglitly connate, ^-f line long. Petals 

 puberulous ; outer broadly elliptical, scarcely 2 lines broad ; base incurved ; 

 inner obovate-cuneate, with a thick claw. Stamens about 9-10 ; apthers 

 extrorse, with very short parallel cells ; connective not produced above, but 

 dilated behind the cells into a triangular appendage. Carpels 6-8 ; ovary 

 shortly pilose ; style linear, obtuse, glabrous, minutely notched or sulcate at 

 top; ovules about 3 superposed. Fruit-cai-pels 1-3-seeded, ^-l^ in. long, 

 narrowed between the seeds, glabrous, on stipes of 1-5 lines. — Uvaria ?

2. C. Mannii, Oliv. A climbing shrub, attaining 50 ft. ; the extremi- 

 ties rusty-pubescent or shortly pilose at first. Leaves membranous, obovate- 

 oblong, shortly and rather abruptly acuminate, glabrous above unless on the 

 nerves, more or less pubescent or at length glabrate beneath ; midrib and 

 parallel Literal nerves prominent below, 5-8 in. long, l|-3 in. broad. Flowers 

 fascicled, on simple or forked peduncles or in fasciculate panicles, often from 

 the axils of fallen leaves ; the peduncles sometimes repeatedly forked and very 

 numerous, with minute bracts, forming large clusters from knotted portions 

 of the old wood ; ? 2-3 lines diam., ^ I'^ther smaller, depressed-globose. 

 Sepals ovate, |-f line long. Outer petals deeply concave, as broad as long, 

 very thick towards the apex, about 2 lines broad, puberulous. Inner petals 

 oblong-cuneate, obtuse, equalling or shorter than the carpels. Male fl. : Sta- 

 mens about 7, diverging from the centre, surrounded by numerous very minute 

 gland-like staminodia ; anthers oblong, obtuse, connective not produced ; 

 carpels 0. Female fl. : Carpels numerous (about 60) ; ovaries pilose ; stigma 

 sessile, globose or rounded-oblong, sulcate, glabrous ; ovules 5, uniseriate.
