102, A. Wilesianum, Hook.; large qnadripinnate, pinnae all 

 distant lanceolate acuminate, pinnules dark brown-green sub- 

 chartaceous scarcely glossy ovato-lanceolate falcate obtusely 

 acuminate obliquely cuneate at the base superior base trun- 

 cate upper margin and sometimes the apex crenato-lobate, 

 lobes of the upper margin soriferous, sori in a crenature or 

 sinus of the lobe, involucres reniform rather large firm thick, 

 stipes ebeneous glossy glabrous, vachis rufo-pubescent on the 

 under side. (Tab. LXXXIII. C.) An A. crenatum, Willd.

Hab. Jamaica, Wiles (in Herb. J. Smith). Tabasco, Mexico, Linden, 

 Fil. n. 1903. — This appears distinct from any species I know. Can it be 

 the A. a'enatum of Willdenow ? who quotes Plumier, t. 53, which is not a 

 very bad representation of this species. If so, it is a native of Martinique 

 and St. Domingo also. 



10.3. A. Brasiliense, Raddi ; frond rather large qnadripin- 

 nate, pinnae approximate all broadly lanceolate acuminate, 

 pinnules closely placed membranaceous olive-brown (when 

 dry) patent oblong subfalcate obtuse obliquely cuneate at the 

 base truncate at the superior base lobed at the upper margin, 

 the lobes crenate and soriferous, sori 5 — 7 on the superior 

 margin I on each lobe, involucres short-oblong reniform 

 convex rather large, stipes and rachis ebeneous glossy, the 

 underside ferrugineo-pubescent. A. Brasiliense, liaddi, Fil. 

 Brasil. p. 50, t. 76. A. pubescens, Raddi., Syn. Fil. Brasil. 

 n. 129. — Plum. Fil. t. 53, according to Raddi, (hut scarce- 

 ly so). 



Hab. Brazil, near Rio, Raddi, Mrs. Caleotl, Gardner, n. 59, Burchell 

 Herb. n. 1816, Tiveedie, n. 1132. Bahia, (Herb. noslr.J. — All my speci- 

 mens are very uniform in their appearance, and the figure of Raddi in the 

 • Fil. Brazil.' is a very good representation of a lower branch. In our spe- 

 cimens the pinnules are generally a little shorter than that figure shows 

 them to be, and a little more closely placed. Raddi cites, without any 

 doubt, as a synonyme to this, Plumier s tab. 53, which is quoted by Will- 

 denow for his A. crenatum : and the figure is more like A. cristatum than 

 the present species. 



104, A. cardiochlfoia, Kze, ; large tripinnate, pinnae all 

 lanceolate shortly acuminate, pinnules pale rather bright green 

 membranaceous horizontally patent crowded elliptical oblong 

 (almost a parallelogram) very obtuse nearly straight, the base 

 obliquely cuneate superior base truncate, superior margin 

 and apex lobed and serrated, lobes soriferous, sori on the
