Hab. Dry rocky places, near the summit of the Sierra <le Natividade,Province of Govaz, Brazil , Gardner. — j3. Cerro of Santana, Guayaquil , ElEquador, Professor W. Jameson. —The present species seems to me verydifferent from any previously described one, and to unite the trapeziformgroupe with the Capillus-Veneris form. In no other individual of the pre-sent division is the involucre situated at the bottom of a deep sinus of alobe ; yet the size of the pinnules and general aspect of the plant induceme to place it here.

72. A. amplum, Pr.; “ fronds subovate dilated below tri-above bi-pinnate, pinnules petiolate alternate rhomboid ro-tundate or obtuse incised at the upper margin, incisuresemarginate serrulate, involucres reniform, stipes and rachisvery glabrous.” Presl, Reliq. Hank. p. 63.

Hab. Mexico and Guayaquil , Htenlce. —“ Frond 2 feet high, a foot and ahalf broad: pinnules 6 lines long, 5 broad.’’ The author observes, “ AffineA. trapeziformi, L. et prasertim A.-offini, Willd. ; apriore differt pinnulisminoribus rotundato-obtusis, incisuris emarginatis, soris lunatis, nec sub-lunatis, a posteriore pinnulis exaete rbombeis, incisuris denticulatis.”—Nowthe A. trapeziforme of Linnsus is, as is well known, a species of verymarked character: the A. affine, is, according to Willdenow , a New Zea­ land plant, and of which he observes “ sequeuti (A. Capillo-Veneris!) uffi-nior, quam A. trapeziformi;’ so that it becomes extremely puzzling toknow where to place this.

,73. A. Capillus- Veneris, L.; frond ovate tri-quadri-pinnate,pinnules delicate membranaceous glabrous obliquely broad-cuneate (sometimes approaching to rhomboid) tapering into arather long slender petiolule, the superior margin deeply andirregularly inciso-lobate, lobes very obtuse or truncate sori-ferous (sterile ones subinciso-dentate), sori as broad as the lobeoblong or subreniform, stipes and slender rachis everywhereebeneous glossy and quite glabrous.
