lated, differ from one another as much as they do from the type 
of Rothrockia, and if much stress was put upon the construction 
of the corona, each could be considered a distinct genus. 
Rothrockia umbellata. Stems twining, 1-1.5 m. high, hir- 
sute; leaves opposite, cordate, ovate-acuminate, 4 cm. wide, 7-8 
cm. long, on petioles about 4 cm. long, slightly hirsute, lighter- 
colored on the lower surface; umbels or racemes axillary, 1-6 
flowered, peduncles 2-3 cm. long, hirsute, pedicels bracteate at 
base, 2 cm. long; corolla rotate, 3.5 cm. in diameter, yellowish- 
green, deeply 5-cleft; lobes ovate-oblong, the upper faces fur- 
nished with short whitish corolline processes, except where dex- 
trorsely overlapped by the adjacent lobe in the bud; corona 5- 
lobed, thick and fleshy, especially about the lower part near the 
base, furnished with a thickened band that is somewhat free and 
2-lobed near its middle, with rounded lateral lobes, and from the 
sides a caudate process 1.5 mm. long; stigma abruptly produced 
from the top into a column having a spherical apex; follicle 12- 
15 cm. long, fusiform, glabrous. 
Not uncommon in the Cape Region about the base of the 
mountains. 
Rothrockia fruticosa. Stems woody, twining, 2 m. high, 
hirsute throughout; leaves cordate, ovate-acuminate, 3 cm. 
wide, 4 cm. long on petioles about 2 cm. long; flowers 
solitary or umbellate with pedicels 2 cm. long, bracted at 
the base; corolla brown-black, deeply 5-cleft; lobes ovate; 
corona 5-lobed, thick and fleshy, with two teeth at the upper 
edge near the middle of the lobes, the lateral teeth not well 
developed, the caudate processes arising from the exterior of the 
- lobe prominent, 4 mm. long, 3-4 times exceeding it, these tails 
are united by a somewhat membranaceous, crenate-dentate con- 
nective, making the lobe somewhat double; stigma produced 
from the top into a column having a capitate apex that is sur- 
rounded by ten globular projections; follicle fusiform, 15 cm. 
long, glabrous. 
Collected near Santa Anita, Cape Region, 
PATTALIAS PALMERI Watson. This is a common plant grow- 
ing near the coast, often in the sand of the shore, from Todos
