into oMnnc; blimt-toothed ultimate divisions ; texture thinly herbaceous ; rachis 

 rigid, zizgag, dark-brown, tomentose, and the under surface of tlie frond liair^' ; 

 sori very small, placed in the sides of the lobes of the segments or ultimate 

 divisions. — Hk. Sp. 2. p. 67. 



Hab. Cape Colony, Kaffraria, Natal, and Zambesi Land. — A well-marked plant. 



§§ Aspidotis, iVw^to//. Fronds small, densely tufted. Sp. 11. 



11. n. (Aspid.) cali/ornica, Hk. ; st. densely tufted, about 6 in. 1., strong, 

 erect, brown, glossy ; fr. about 3 in. each way, deltoid, quadripinnatifid ; lower 

 piimce deltoid, the pinnl. of the lower side much larger than the others, cut down 

 to the rachis into numerous secfm., which are again very sharply cut nearly to 

 the centre ; texture subcoriaceous ; rachises naked, glossy, dark-brown ; sori 

 roundish, 2 to G to a segm., placed at the base of the sinuses. — Hk. Sp. 2. p. 71.

Hab. California. — This has quite the babit of the more finely-divided coriaceous species 

 of Eucheilanthes {C. tenuifolia, &c.).

Sori terminal or nearly so on the veins, at iirst small, subglobose, afterwards 

 more or less confluent. Invol. formed from the changed reflexed margin, 

 roundish and distinct, or more or less confluent, but not quite continuous. 

 Tab. III. f. 25. A considerable genus, with mam/ species extending beyond the 

 tropics, the fronds mostly tender a foot long, often under six inches, tri- or quadripin- 

 iiatffd, subcoriaceous in texture. Veins free in all the species. Adiantopsis c?//ftTS 

 from Hypolepis in habit and the position of the sori, and Eucheilanthes from 

 Pellaea and Pteris, by its more or less interrupted involucres. It is very difficult to 

 draw the line between Cheilanthes and Nothochlscna, ichich is the corresponding 

 tion-indusiate genus. 



§ Adiantopsis, Fee. Involucres distinct, roundish, confined to the apex of a single 

 veinlet. Sp. 1-13.

 pinnate ; pinnce 1-f in. 1., | in. br., oblong, obtuse, auricled at the base on the

 texture subcoriaceous ; rachis polished, naked, both surfaces naked ; sori small, 

 roundish, distinct but contiguous. — Hk. Sp. 2. p. 80. t. 101. A. 



Hab. Cape Colony, on mountains from 1-3,000 ft., and found also in Java. — Closely 

 resembles in habit some of the Platylomce.

 ginous hairs ; fr. 6-8 in. 1., lanceolate- oblong, bipinnate ; />m?;oe spreading from 

 the rachis at right angles, the lowest 2 in. 1., oblong-obtuse ; pinnL 4-5 lin. 1.,
