the length of the obtuse sepals, obovate (or obcordate ?) 
much attenuated towards the base, white, slightly tinged with 
rose towards the summit.  Siliques sessile, lanceolate, 
glabrous, 7-8 lines long, nearly 2 lines broad, with a 
cylindrical, bluntish, deciduous beak of one line in length ; 
valves very flat, scarcely torose, sometimes a little undu- 
lated at the margin, very slightly reticulated, and traversed 
by a middle nerve hardly more conspicuous than the very 
thin veins. Seeds 3-4 in each cell, disposed in a single 
series; cotyledons exactly as described in H. macrosperma, 
by De Candolle.

Linn. fil. suppl. p. 297. Thunb. Fl. Cap. p. 492. — Branches 
of the thickness of a common pen, strongly marked with 
aeutely prominent parallel lines decurrent from the base of 
the leaves. Leaves sessile, scarcely attenuated at the base, 
the lower ones 18-20 lines long, and 2-24 lines broad, of a 
somewhat coriaceous texture, with a strong middle rib 
prominent underneath, and two obsolete nerves running near 
margin which is slightly recurved, so as to render the 
inferior face somewhat concave; both surfaces are, besides, 
minutely wrinkled. Racemes simple ; pedicels permanently 
erect, 6-8 lines long. Sepals almost patent, lanceolate, acute, 
reddish, about half as long as the petals, which are obtuse, 
attenuated into a short unguis, and of a pale pink colour ; 
stamens not longer than the calyx. Ripe pods 2} inches 
long, 2 lines broad, attenuated at the base into a short
