II. CYATHEACEiE. Endl. 
III. CYATHEA. smth. (Arborescent) (2 Species.) 
4. Cyathea Dregei. Kze. Unarmed, fronds 2 pinnate, 
coriaceous ; pinnules lanceolate, pointed, deeply pinnatifid, 
smooth above, paler below, and rufo-tomentose on and near 
the racliis beneath ; segments oblong-ovate, subf alcate, obtuse, 
entire or serrated ; sori on the lower half of the segments 
immersed in rufous wool ; involucre hemispherical, breaking 
irregularly; Stipes short, rough, scaly.— -Hook. Spec. Filic., 
vol. 1, p. 23., Tab. 10, tig. B., and Tab. 17, fig. A. Kunze 
Linnsea, vol. 10, p. 551. 
In forests near Bethel (Kaffraria), and the Magalisberg 
(Zeyher), in a rocky valley at the great cataract between Omzam- 
woobo and Omzarncaba (Drege), near the Moore River. (Natal. 
Plant.) v. s . 
5. Cyathea Burhei. Hook. Fronds 2-pinnatifid, mem- 
branaceous ; pinnules lanceolate, bluntly acuminate, 2-pinna- 
tifid ; racliis partially woolly, smooth above ; segments 
oblong-ovate, obtuse, entire, the costa hairy at the base. Sori 
few, often solitary ; involucre globose, with an irregular 
opening at the top. Stipes tubercled with small prickles, and 
at its base, and that of the main rachis, clothed with glossy 
brown, chaffy scales.— -Hooker Spec. Filic., vol. 1, p. 23, 
Tab. 17, B. 
In forests at Magalisberg. (Zeyher.) v. s. 
IV. Alsophila. r. br. (Arborescent) (1 Species). 
6. Alsophila Capensis . J. Smth.* Unarmed ; fronds 3- 
pinnate ; pinnae lanceolate-acuminate, membranaceous, deeply 
pinnatifid ; segments narrow-oblong, acute falcate serrated 
(rachis and costa, with small deciduous scales), veins simple, 
or rarely forked. Sori cylindrical, generally solitary at the 
bases of the lowest veins, on the upper half of the segment.— 
* Very curious leaflike appendages issue luxuriantly from the base of the 
stipes in this species. They are flaccid 3-pinnate abortive jronds six or eight 
inches in length. Their pellucid membranaceous ■pinna are dichotomously 
branched, and their narrow, linear acute lobes, forked, or irregularly split. 
Their appearance is that of a parasitical Trichomanes in its barren state; and 
they were described erroneously as Trichomanes incisum, by Thunberg 
and as T. cormophilum, by Kaulfuss.
