118 COMPOSIT ( Harv.) | Denekia. 
Sub. gen. 2, Henorocyna. Fem. fi.-heads one-flowered, with linear inv.-scales. 
Achenes sparingly woolly.—Leaves rugose, 3-lobed at the summit. 
Lys. 5-7 inches long, trifid; panicles axillary, shorter 
than leaves (3) trilobus. 
Sub. gen. 1. EuraRcHONANTHUS. (Sp. 1-2). 
1. T. camphoratus (Linn. Sp. 1179); leaves lanceolate-oblong (or 
obovate), acute at base, subacute or obtuse at apex, quite entire or 
denticulate, the adult glabrous and tessellato-reticulate above, tomentose 
and penninerved beneath ; panicle terminal, many-headed. DC. 4. .

Var. 8. Litakunensis; leaves pitted-reticulate above. 7’. Litakunensis, DC. 1. ¢.

Has. Throughout the Colony, common. £8. Litaku, Burch. Rhinoster Kopf,

A large shrub, with a strong, balsamic odour. Leaves 3-5 inches long, $-15 I. 
wide, the young ones densely velvetty above, the old glabrate and finely reticulate, 
the reticulations either flat or hollow in the middle, as if pitted. I cannot distinguish 
T. Litakwnensis, so far as Drege’s specimens are authority. ‘The pitted and non- 
pitted reticulation varies in the same specimen, and seems to arise either from some 
condition of the leaf, or irregularity in drying. The leaves also vary much in size. 
2. T. minor (Less. Syn. p. 208); leaves (small) obovate, oblong, or 
linear-oblong, obtuse, entire, the adult glabrous and tessellated above, 
thickly tomentose, and indistinctly nerved or nerveless beneath; heads 
axillary and terminal, either solitary or shortly racemose, the racemes 
few-headed.—7’, obovatus, DC. and angustissimus, DC. l. c. 435.

and Tambukiland, Ecklon! Zululand, Miss Owen! Cape, Bowie! Basutuland, 7.

Smaller in all parts than 7. camphoratus, with fewer fi.-heads and less branching 
inflorescence ; but possibly merely a dwarf variety. Leaves commonly 1-14 inch 
long, 3-5 lines wide. The fi.-heads are similar to those of 7’. camphoratus, and are 
‘sometimes sessile, or subsessile, sometimes distinctly pedicellate, the pedicel 2-4 
lines long. I find the leaves to vary in form on the same specimen. 
Sub. gen. 2. Henotocyna, DC. (Sp. 3). 
3. T. trilobus (DC. 1. c. 432); leaves cuneate, shortly 3-lobed at the 
abrupt summit, sinuato-dentate at the sides, becoming glabrous and 
corrugated above, penninerved, reticulated and hirsuto-tomentose be- 
neath ; panicles axillary, shorter than the leaves; scales of the fem. 
invol. linear, elongate. 
Has. Omtendo, Drege! Port Natal, Gueinzius! (Herb. D., Hk., Sd.,) 
Branches bare of leaves below, closely leafy at the summit. Leaves petioled, 
sub-horizontal, 5-7 inches long, 1$-2} inches wide at the trifid point, green and 
wrinkled above, whitish hairy beneath. Racemes slightly branching, 2-4 inches 
long, woolly. Young achenes much less woolly than in other species. Very distinct 
in habit from the other species. 
Subtribe 4. Inutez. Heads never dicecious ; if heterogamous, the marginal fl. 
female, with ligulate (sometimes very short) corollas. Anthers t tailed. (Gen. 31-38). 
XXXI. DENEKIA, Thunb. 
Heads many-f., heterogamous ; marginal fl, in several rows, female,
