the 2 Cape species, both of wliich occur everywhere in liumid, warm re- 

 gions, tlie divisions are roundish and equal-sided, and the sori and invoh^cres 

 globose. 



11. HYPOLEPIS, Bcriili. non Pers. 



Sori globose, confined to the sinuses of the ultimate divisions 

 of the decompound frond, with involucres of the same shape. 

 — Pappe and Rawson,2^. ii7,and Cheilanthes, p. 34!, in part ; 

 Book, and Baker, Syn. Fil. p. 128. 



Fronds ample, decompound, the ultimate divisions small, the veining 

 always free. — 2 Cape species. 



12. LONCHITIS, Linn. 



Sori oblong or linear, confined to the sinuses of the divisions 

 of the frond. Veins joining copiously. — Pappe and Bawson, 

 p. 38 ; Hook, and Baker, Syn. Fil. p. 128. 



A single Cape species (with 2 varieties). Had probably better be united 

 ■with Pterin. 



13. CHEILANTHES, Swartz. 



Sori commencing as distinct globose dots at the ends of the 

 veins, but often becoming more or less confluent. Involucres 

 globose, quite distinct or often more or less confluent. — Bappe 

 and Bawson, p. 33 {in part) ; Hook, and Baker, Sijn. Fil. p. 

 131. 



Fronds small and coi'iaceous, the veining always free. — Of the 5 Cape 

 species 2 belong to sect. Adiantopsis, in which the sori and involucres re- 

 main pei-manently distinct, and 3 to sect. Eucheilanthes, in which they 

 show a more or less marked tendency to unite as the plant grows older. 



14. PELLJEA, Link. 



Sori and involucres linear, but not so clearly continuous as 

 in Bteris. Proud of small size, and usually coriaceous in 

 texture. — Hook, and Baker, Syn. Fil. p. 141. Allosorus {in 

 greater part), Pappe and Bawson, p. 30, and Cryptogamma, I.e. 

 p. 32. 



Intermediate between Cheilanthes and Pteris in fructification, with the 

 general habit of the former. — 12 Cape species, all but 1 with free venation ; 

 2 others belonging to sect. Platyloma, in which the involucre is so narrow 

 that it is soon hidden as the fruit developes. 



15. PTERIS, Linn. 



Sori and involucre both linear and quite continuous. Pronds 

 ample and herbaceous. — Hook, and Baker, Syn. Fil. p. 153. 

 Pteris, Campteria, and Allosorus {in part), Pappe and Bawson. 



5 Cape species, belonging to sect. Eupteris, which has free veins, and a 

 Buberect caudex ; 1 (aquilina), to sect. Pcesia, which has a wide- creeping
