Hab. Haguef, Arabia Felix, Botta. — " Allied to CA<'?7rt«</iP.<f fulchella. 

 This plant, the Ch. pulchella, together with a new Abyssinian species'' 

 (not further noticed hy the author), "exhibit, in their younger state, the 

 pinnules wholly covered by an indusium, which is smooth and shining and 

 gives to the inferior surface a coppery appearance. Notwithstanding this 

 character, these three ])lants belong to the group of Ch. farinosa, remarka- 

 ble in the form, the consistence and colour of the stipes. The mode of divi- 

 sion of the fronds and the bifurcation of the inferior pinnule, while giving 

 to these plants a peculiar character, unite them much more intimately with 

 Cheilanthcs, than with Allosorus, to which genus M. Presl refers them.'' — 

 Of this I have seen no authentic specimen, and am unable to refer it from 

 the description to any known species.

Hab. Arabia Felix, Fiirskahl. — I am unacquainted with this species, 

 which Swartz and Willdenow refer to Cheilanthes, but which others refer 

 to P<«-w, and Presl, perhaps justly, considers identical with his .4//osorMS 

 hastatus (Pteris Sw.) 



62. Ch. hirsuta, Link ; " frond tripinnate oblong in cir- 

 cumscription, pinnules lanceolate obtuse crenulate attenu- 

 ated at the base, involucre breaking into a thin lax tomentura 

 (indusio in toraentum tenue laxura abeunte) and covering the 

 whole under side of the pinnules." Link, Hort. Berol. ii. p.

Hab. Mexico, {Kunze). — " Frond a foot and more long, pinnules 2 — 6 

 lines long, outer ones (externa) very long, a little more than a line \vide." 

 — 1 am unacquainted with this plant, but Kunze retains it as a species of 

 Cheilanthes, and Link says of it that it has the habit of Pteris and es- 

 pecially of Pteris leptophi/lla, Sw. (formerly Cheilanthes spimdosa, Link, 

 according to Presl). Link further adds under this species, " Ch. crenulata, 

 Hort. Ber. ii. p. 42, vix ab Ch. hirsuta diversa. Ch. crenatam quoque 

 colimus; an Ch. crenata, Kze., Linnaea, ix. p. 84? Planta infans frondi-
