oblong, tertiary and the lacinioc roundish-ovate, all glabrous 

 above beneath paleaceo-hirsute, involucres marginal crenu- 

 late and as well as the sori conliiuious, sti])cs flexuose spar- 

 ingly and the rachises densely paleaceo-hirsute purple, caudex 

 creeping branched flexuose." Kze. (Tab. Cll. A.) Kimze, 

 ill Liiiuoea, x. p. 538. 



Hab. Rocky shady places in Sneeuwbergen, Drege. — " Approaches Ch. 

 hirla and somewhat Ch. lendujera ; hut it dilTeis from the hitter in the 

 curved pinna; and very narrow scales, from the former in the more com- 

 pound frond, remote pinnae, with the pinnules twice as laro^e and the stipes 

 glabrous. A foot high." Kze. — Our specimens from Drege, marked Ch. 

 induta, Kze., rt.,are much less paleaceo-hirsute (hence a good deal resembling 

 Ck. multifida, only that is quite glabrous) than those marked B-, which are 

 very paleaceo-hirsute beneath, while the upper side of the frond and sti- 

 pes and rachises are glabrous. — Our figure is taken from the specimen 

 marked /3. 



33. Ch. piibescens, H. B. K. ; "fronds at the apex bi- at 

 the base tripinnate,- pinnides oblong or obovate-rotundate 

 obtuse subsessile entire upper ones confluent, rachises pubes- 

 centi-hirsute, stipes glabrous." H. B. K. Nov. Gen. Am. i. 

 p. 21. Presl, Tent. Pterid. p. 160. 



Hab. At the bases of the mountains near Xalapa, IMexico : elevation 

 4,200 feet. H. B. K. — " Fronds 4 — 5 inches long, at the apex bi- at the 

 base tripinnate: primary pinna? subopposite, lower ones scarcely an inch 

 long, superior ones confluent; secondary pinnas alternate, 3 lines long: pin- 

 nules alternate, obovato-rotundate or oblong, subsessile, pubescent, entire, 

 a line long, terminal ones smaller, confluent. Universal and partial rachis 

 nearly terete, black, pubescenti-hirsute. Stipes as long as the frond, te- 

 rete, black, glossy, pubescent above, towards the base clothed with subulate, 

 diaphanous, ferruginous scales. Sori marginal, at length confluent. Spo- 

 rangia ferruginous. ludusium crenate, diaphanous, glal)rous.'' H. B. K. 

 — This species is acknowledged as such by Presl and others, yet I do not 

 anywhere find its affinities alluded to. 



34. Ch. MacLeanii, Hook. ; roots tufted from a knobbed 

 scaly caudex, whole plant clothed with spreading glandular 

 jointed hairs the shorter hairs the most generally glandulife- 

 rous, stipites aggregate 2 — 4 — 5 inches long and as well as 

 the main rachis ebeneous glossy, fronds 6 — 8 inches or even 

 a foot and 14 inches long linear-oblong bi- subtripinnate 

 membranaceous but rather rigid dark dirty-brown when dry, 

 primary pinna? petiolate subopposite in rather distant pairs 

 especially the lower ones long-ovate, pinnules large (for the 

 size of the plant) broad ovate the lower ones petiolulate and dis- 

 tant, upper ones confluent all lobed or pinnatifid very obtuse, 

 involucres squamiform semiorbicular glossy-brown close press- 

 ed over the sorus all free but closely placed. (Tab. CX. B.)
