part of the Central African table-land, and thence spread southwards<br />

as far as Port Elizabeth, and westward as far as Angola. The<br />

following key may be of use in distinguishing the species :<br />

A. Leaves ovate, with revolute margins,<br />

a. Leaves glabrous ; peduncle short.<br />

Gynostegiura shorter than the anthers 1. paili/olium.<br />

Gynostegium as long as the anthers . 2. con/usum.<br />

b. Leaves sparsely hairy ; peduncle short.<br />

Leaves twice as long as broad ... 3. parviflorum.<br />

Loaves thrice as long as broad . . 4. (ieirardi.<br />

c. Peduncle 3 cm. or more in length . . 5. pedunculatiun.<br />

B. Leaves elongate-lanceolate, tapering very<br />

gradually from a broad base, with crisped<br />

undulate margin (except 9).<br />

Petals bearded with long chaft'y hairs. 6. undulatum.<br />

Petals bearded with short silvery hairs 7. Stuckemtrumense.<br />

Petals not distinctly bearded ... 8. (jumi)hocarpuides.<br />

Gynostegium much longer than the<br />

anthers 9. (mgolcnse.<br />

C. Leaves linear-lanceolate.<br />

Margin of leaf scabrid 10. involucratum.<br />

Margin of leaf not scabrid .... 11. Hulubii.<br />

2. X. confusum, n. sp. Stem stout, somewhat fleshy, and<br />

bifariously hairy. Leaves elliptic-ovate, retuse, apiculate ; margin<br />

denticulate and thickened. Peduncles or short. Bracts<br />

small, subulate. Pedicels 7-15. Sepals linear-lanceolate, acute,<br />

almost as long as the petals. Petals ovate, subacute, with reflex<br />

margins. Corona-scales, viewed from without, broadly obovate<br />

(the tip and sides towards their buses are really doubled inwards),<br />

and rising to about half the height of the anthers. Anthers very<br />

sliort, not overtopping the gynostegium. Leaves 5-15 cm. long,<br />

2-0 cm. broad. Pedicels 1-5 cm. long. Flowers about 1 cm. long<br />

and 8 nnn. in diameter. — Natal, Mrs. Saunders I Gerrard 1282 !<br />

3. X. parviflorum Ilarv. MS. Stem sparsely and roughly<br />

hairy. Leaves ovate or triangular-ovate, acute or acuminate,<br />
