4. Cyathea DregeL Kze. Unarmed, fronds 2 pinnate, 

 coriaceous ; pinnules lanceolate, pointed/ deeply pinnatifid, 

 smooth above, paler below, and rufo-tomentose on and near 

 the rachis beneath; segments oblong-ovate, subfalcate, 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. Filler,

 Plant.) 7). s, 



5. Cyathea Burhei. Hook. Fronds 2-pinnatifid, mem- 

 branaceous ; pinnules lanceolate, bluntly acuminate, 2-pinna- 

 tifid ; rachis 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,

IV. Alsophila. r. BR. ( Arborescent ) (1 Species). 



6. Alsophila Capensis, J. Smth.* Unarmed ; fronds 3- 

 pinnate ; piiince lanceolate-acuminate, membranaceous, deeply 

 pinnatifid ; segments narrow-oblong, acute falcate serrated 

 (rachis and costa, with small deciduous scales), veins simple, 

 or rarely forked. Soi'i cylindrical, generally solitary at tho 

 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 J ronds six or eight 

 inches in length. Their pellucid membranaceous pimi(e 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. cormophilura, by Kaulfuss.
