Hab. Dry vocky jiluces, near the summit of the Sierra dc Natividarle, 

 Province of Goyaz, Brazil, Gardner. — /3. Cerro of Santana, Guayaquil, El 

 Equador, Professor W. Jameson. — The present species seems to me very 

 different from any previously described one, and to unite the trapcziform 

 groupe with the Capillus-Veneris form. In no other individual ol the pre- 

 sent division is the involucre situated at the bottom of a deep sinus of a 

 lobe ; yet the size of the pinnules and general aspect of the plant induce 

 me to place it here. 



72. A. am plum, Pr. ; " fronds subovate dilated below tri- 

 above bi-pinnate, pinnides petiolate alternate rhomboid ro- 

 tundate or obtuse incised at the upper margin, incisures 

 emarginate serrulate, involucres reniform, stipes and rachis 

 very glabrous." Presl, Reliq. Hcenk. p. 63. 



Hab. Mexico and Guayaquil, //«Hie. — " Frond 2 feet high, a foot and a 

 half broad : pinnules lines long, 5 broad.'' The author observes, " Afiine 

 A. trapeziformi, L. et prtesertim A. affini,\N\\\d. ; a priore differt pinnulis 

 miuoribus rotundato-obtusis, incisuris emarginatis, soris lunatis, nee sub- 

 lunatis, a posteriore pinnulis exacte rhombeis, incisuris denticulatis." — Now 

 the A. trapezifurme of Linna:us is, as is well known, a species of very 

 marked character: the A. affiiie, is, according to Willdenow, a New Zea- 

 land plant, and of which he observes " sequenti (A. Capillo-Veneris .') affi- 

 nior, quam A. trapeziformi;" so that it becomes extremely puzzling to 

 know where to place this. 



* * Capilhis- Veneris groupe. (Sp. 73 — 93.) 



73. A. Capillus- Veneris, L. ; frond ovate tri-quadri-pinnate, 

 pinnules delicate membranaceous glabrous obliquely broad- 

 cuneate (sometimes approaching to rhomboid) tapering into a 

 rather long slender petiolule, the superior margin deeply and 

 irregularly inciso-lobate, lobes very obtuse or truncate sori- 

 ferous (sterile ones subinciso-dentate), sori as broad as the lobe 

 oblong or subreniform, stipes and slender rachis everywhere 

 ebeneous glossy and quite glabrous. Linn. Sp, PL j)- 1558.

Hab. Throughout the temperate and warm parts of Europe : in Britain 

 confined to the West of England, Wales and Ireland (said to have been 

 found in Scotland) : in the South of France growing in the greatest profu- 

 sion, and luxuriating in the moist, perpendicular sides of the wells. North 

 of Africa, and African Islands of the Mediterranean. Throughout the East 

 Indies, but chiefly in damp hilly districts, Malabar, Nepal, Kamaoun, &c.,
