to the left. Stamens in the widened part of the tube; fila- 
ments short; anthers free from the stigma, ovate, usually rather 
obtuse, shortly and obtusely 2-lobed. at the base; anther-cells 
polliniferous and dehiscing to the base. Disc annular or cup-shaped, 
entire or slightly lobed. Carpels 2, free or more or less coherent ; 
style filiform or columnar; stigma capitate, shortly cylindric, 
minutely papillose and slightly viscous, with a basal deflexed rim 
or membrane and a usually very short slightly bilobed apiculus 
rising from a shallow depression; ovules 2 in each cell, col- 
lateral. Mericarps 2 (or often 1 by abortion), free or more or 
less united, drupaceous ; pyrenes crustaceous, 1—2-seeded, more or 
less compressed. Seeds ovoid; endosperm fleshy ; cotyledons flat ; 
radicle straight or recurved. 
Mostly glabrous trees or shrubs. Leaves opposite or verticillate, those of a 
whorl often very unequal; axillary stipules 0; axillary glands numerous, in a 
dense fringe or in clusters, frequently secreting resin. Inflorescences terminal 
or pseudo-axillary, peduncled, few- or many-flowered, often repeatedly 2-3- 
chotomous, compound, umbelliform or corymbose, rarely racemiform ; flowers 
small.

South Africa, :

gradually acuminate at both ends; petioles 4-1} in. 
long, slender a wp vee eas =i 
Leaves oblanceolate (14-23 in. broad), acute or sub- 
acuminate, long attenuated at the base and more or 
less decurrent on the usually short and stout petiole.. (2) natalensis. 
1. R. caffra (Sonder in Linnea, xxiii. 77) ; a large tree, 50-60 ft. 
high, quite glabrous; young branches angular or almost terete, 
stout, blackish-brown when dry; leaves in whorls of 3-5, unequal, 
lanceolate, long acuminate, long cuneate at the base, 3-8 in. long, 
8-11 in. broad, membranous, rather firm; secondary nerves 20-30 
on each side, straight or curved, subhorizontal; veins obscure or 
more or less distinct below; petioles up to 1} in. long; cymes 
dense, at the ends of the secondary or tertiary rays of large umbels ; 
flowers shortly pedicelled or subsessile; peduncles 1-2} in. long; 
primary rays 3-11 in. long, secondary rays 1-1 in. long; calyx 
1-2 lin, long ; lobes ovate, acute ; corolla white; tube 1}-2 lin. 
long, mouth very hairy ; lobes ovate, very short, subacute ; carpels 
connate at the base in the flower, more or less fused in the fruit or 
usually only one developing; style glabrous, 3 lin. long; stigma 
truncate with a reflexed membrane ; fruit a simple drupe (by abortion), 
obovoid or almost globose, 3 lin. long, or an obcordate twin drupe.
