1. D. Dregeana (Sond. in Linn. 23. p. 18); branches terete, glabrous ; 
leaves on long, pubescent petioles, cordate, acute or acuminate, angled or 
even 3-lobed, toothed, minutely stellato-pubescent, 5-—7-ribbed ; pedun- 
cles filiform, axillary, longer than the leaves ; umbels 2—4-flowered, with 
hairy pedicels ; involucral leaflets broadly ovate, acuminate, and, as well 
as the lanceolate, reflexed sepals, tomentose ; the 5 sterile stamens spa- 
thulate, as long as the 5-fid style ; ovary globose,tomentose. Leewwen-

A shrub or small tree, well-covered with aspen-like leaves and showy flowers, on 
long peduncles, springing from the axils of the uppermost leaves. The flowers are 
upwards of an inch across (rosy ?), and the petals wither without falling off, remain- 
ing expanded. : 
2. D. Natalensis (Sond. in Linn. 23. p. 18); branches terete, glabrous ; 
leaves on long petioles, cordate, acute or acuminate, somewhat angular, 
toothed, minutely stellato-pubescent, 5—7-ribbed ; peduncles filiform, 
axillary, longer than the leaves, umbels 4—6—8-flowered, with canescent 
pedicels; invol. leaflets narrow-subulate, and, as well as the lanceolate, 
reflexed sepals, canescent ; the 5 sterile stamens clavate, as long as the 
5-cleft style ; ovary globose, tomentose. Leewwenhoekia tiliacea, EL. Mey.!

Has. Port Natal, Gueinzius/ Drege! (Herb. T.C.D., Sond.). 
Closely resembling D. Dregeana, from which it is best known by its narrow subu- 
late involucral leaflets. The flower buds are more fusiform and less tomentose than 
in D. Dregeana, and the umbels have usually more rays. 
3. D. rotundifolia (Harv.); young branches stellato-tomentose, older 
glabrous ; leaves petiolate, sub-orlicular, very obtuse, repando-crenulate, 
stellato-pubescent on both sides, becoming glabrous above, 5—7-nerved 
and netted on the lower side ; peduncles one or several, tomentose, 
mostly forked, each arm bearing an umbel of 6-12 flowers ; invol. leaf- 
lets narrow-linear, obtuse, shorter than the bud, deciduous and as well 
as the lanceolate reflexed sepals, tomentose ; the 5 sterile stamens 
linear clavate, longer than the 3-5-fid style; ovary globose, tomentose.

Has. Port Natal, Gueinzius, &e. Macallisberg, Burke $ Zeyher! (Herb. T.C.D., 
Hk Ss branched, rigid shrub. Leaves 1}-2 inches broad, somewhat 
cordate at base, strongly netted below and very obtuse. Flowers crowded round the 
ends of the naked branches in many-flowered umbels ; the peduncles long or short. 
Petals white? The involucel is constantly found on the young buds, but soon falls 
away. The style is sometimes trifid.
