and secondary ones generally so, pinnules linear-oblong ob- 

 tuse often pinnatifid shaggy beneath with minute glossy 

 crisped ferruginous scales, involucres copious formed of the 

 reflexed margins of the pinnules continuous rather rigid cre- 

 nato-lobate, rachises compressed and channelled castaneous 

 glossy margined with ferruginous scales, stipes much longer 

 than the frond stout strongly grooved terete slightly scaly near 

 the base. — Allosorus hirsutus, Presl, Relirj. Hank. i.p. 59. 1. 10.

Hab. Andes of Chili, Hanke ; at La Guardia and at Antuco, in South Chili,

 branched). Near Valparaiso, " in marshes," Bridr/es. — A very distinct and well- 

 marked species ; yet, though an old and well-known plant, the descriptions and 

 figure are entirely overlooked both by Fee and M. Gay, and they have made of it 

 a new species of Cheilanthes. The perfect fronds are quite triangular, densely 

 3-4-pinnatc, about 3-4 inches long, beneath of a rich brown, from the deep 

 colour of the rachises, and the dark ferruginous crisped scales, which give a 

 shaggy appearance to the under side of the pinnules, and to the margins of the 

 rachises. Presl's figure well represents the upper side of the plant of the natural 

 size, but it is destitute of any analysis of fructification. He seems to be the only 

 author, except Kunze, to whom this plant is known, yet it is found by every 

 botanist who has sent collections from Chili. 



Dubious Species of Pellsea. 



Allosorus involutus, Pr., from the Cape, Thunberg. — Pteris 

 involuta, Sw. Syn. Fil. pp. 104 and 300. Kunze, in Linneea, 

 X. p. 526, says, "A Thunbergio in Prodromo et Fl. Capensi 

 omissa, mihique plane ignota.'' 



Allosorus Domingensis, Pr., seems to be only known as 

 Pteris Domingensis of Spreng, Herb. 



Allosorus aurantiacus, Pr. ; " fronds pinnate somewhat 

 hairy above, beneath clothed with a golden farina, pinnae 

 opposite deeply pinnatifid, segments ovato-oblong obtuse 

 crenate ciliate," Willd. — Pteris aurantiaca, Cav. Prcel. 1801, 

 n. 659. Willd. Sp. PL v. p. 382.— New Spain, near Chalma, 

 Cav. 



Allosorus sulphureus, Pr. ; " fronds trifoliate, lateral leaf- 

 lets auriculate at the base (' foliis lateralibus folio breviore ad 

 basin auctis'), intermediate leaflet petiolate all pinnated 

 clothed with sulphur- coloured powder beneath/' Cav. Prml.
