28 CONSPECTUS TABULARUM. 
Hazs.—Port Natal, 7. Williamson! Drege, Gueinzius. Near Umgani River, Ger- 
rard and M‘Ken. (Herb. T. C. D.) 
Descr.—A shrub, 8-10 feet high. Branches sparsely pilose or glabrous, 
bluntly 4-angled. Leaves ovate-acuminate, tapering at base into a short, 
winged petiole, 3-5 inches long, 1-2 inches wide, membranous, penni- 
nerved, glabrous or nearly so. Spikes terminal, ovate-oblong or cylin- 
drical, densely many-flowered, bracteate; the bracts subulate. Calyx 
lobes subequal, very long and slender, subulate. Corolla bright red, 
labiate; the upper lip erect, flat, semibifid; lower deflexed, deeply 3- 
parted, the lobes oblong, subacute. Stamens 2, fertile, inserted in the 
throat, exserted, with unilocular, oblique anthers; and 2, abortive, re- 
duced to short teeth. Style filiform, minutely pubescent ; stigma shortly 
bifid. Capsule obovate, tapering much at base ; the cells 2-sceded. 
A handsome shrub, well worthy of cultivation. The genus is named 
after Dr. Rutty, a physician of the last century, author of a natural his- 
tory of the county of Dublin.

S. Harveyanus: floribus axillaribus solitariis subsessilibus. Nees in 
DC. Prodr. xi. p.279. TJ. Anders. in Linn. Soc. Journ., vol. vii., Bot., 
p. 37. 
Hazs.—Caffraria, Drege! No. 4037. Orange River, Burke. British Caffraria, Mfrs. 
F. W. Barber, No. 40. Perie Bush, Caffr., W.S. M.D’ Urban, No. 84. (Herb. T. C. D.) 
Descr.—Stems shrubby, diffuse or trailing, ramulous; twigs thinly 
covered with close-lying, short hairs. eaves ovate or ovato-lanceolate, 
acute or obtuse or taper-pointed, either rounded or tapering at base, 4-14 
inches long, glabrous, except on the midrib beneath. Petioles short, 
pubescent. Flowers solitary, axillary, subsessile, light purple or lilac 
colour. Calyx bracteate at base: the sepals oblong, very blunt, mucro- 
nulate, rigid, concave, striate, glabrous, microscopically ciliolate. Co- 
rolla with acurved, split, internally hairy tube, one-lipped, with 5 blunt 
lobes. Stamens 4, exserted, subequal; anthers one-celled muticous. 
Capsule ovate, stipitate ; seeds one in each cell. 
The genus Sclerochiton, originally founded on this species, differs 
from Blepharis and Acanthopsis, which are its nearest allies, in the 5- 
parted, remarkably stiff and rigid calyx. Dr. T. Anderson, in his re- 
cently published list of African Acanthacer, above quoted, has gene- 
rically united to our 8. African species the Isacanthus Vogelii, Nees, a 
shrub from Cape Palmas of nearly similar floral structure, but having 
spicate, not solitary, white flowers; narrow calyx-lobes, and rough- 
dotted leaves, 2-3 inches long. Our plant grows under trees, by hedge 
rows, and on the borders of woods, where its pretty, purple flowers, 
copiously produced, attract attention. It is, however, perhaps scarcely 
deserving of introduction to an English greenhouse.
