ADIANTUM. 43 



nuled variety, as I have considered it, has at first sight a very different ap- 

 pearance, but some of my Guatemahi specimens exhibit intermediate 

 grades of pinnule. Mathews, n. 1850, is more lax and has more deeply 

 cut pinnules than usual. 



86. A. scahnim, Kaiilf. ; " fronds bi- or tripinnate, pinnules 

 orbicular reniforin denticulate hairy and alho-farinose be- 

 neath, stipes paleaceo-scabrous, rachis very scabrous, sori 

 subcontinuous." Kaulf. En. Fil. p. 207. Hook, and Am. Bot. 

 of Beech. Voy. p. 53. 



Hab. Chili, Chamisso ; Conception, dipt. Deechcy, R. N. — I have only 

 seen one specimen corresponding with KaulCuss' description ; that is from 

 Capt. Beechey's voyage, and without fniclificalion. I dare not venture an 

 opinion on such. The pinnules in shape resemble the more entire form of 

 those of A. Chileme ; the farinaceous substance resembles that of A. sul- 

 phureum, but is white. The name is scarcely appropriate, being only ap- 

 plicable, and not in a marked degree, to the stipes and rachis. 



87. A. Chilense, Kaulf. ; frond ovato-deltoid (a span to a 

 foot long) tripinnate, pinnides all petiolulate coriaceo-mem- 

 branaceous glabrous or hirsute subrhombeo-reniform more or 

 less obliquely cuneate at the base often truncated there, the 

 margin irregularly lobed and the sterile ones denlato-serrate, 

 lobes or lobules retuse (with a broad shallow sinus) soriferous, 

 involucres oblong-reniform coriaceous distant in the more 

 lobed pinnules, crowded in those that are nearly entire, stipes 

 and rachis everywhere ebeneous glossy and quite glabrous.

Hab. a. and /3. Chili, Conception to Valparaiso, Chamisso, Capt. King, 

 R. N., Beecliey, Macrae. Juan Fernandez, JSectero. /3. has been found by 

 Mr. Nuttall, at Monterey, in California, {Herb, nostr.). — The hirsute var. 

 of this plant (and there are all gradations of hairiness) seems to have been 

 generally tal<en for Kaulfuss' A. scabrum : but he expressly says of the 

 leaflets of that plant " foliola subtus albo-farinosa." Poeppig's A. scabrum, 

 from Chili, is simply a hairy state of this. My friend Nuttall's A. dilatatum, 

 mst., from Monterey, Upper California, is identical with this var. Prof. 

 Kunze refers to this species the A. lobatum, Presl, Reliq. Hank., i. p. ()2, 

 t. 10, f. 4 (v. supra, p. 10), but he only judges from the figure and descrip- 

 ti(m : that species is said to be bipinnate and to inhabit Mexico ; it may, 

 however, be the same as A. Chilense, and probably was from Chili ; for the 

 station given of Hreuke's plants are little to be depended upon. 



88. A. sulphureum, Kaulf. ; small tufted ; frond ovate tri- 

 pinnate, pinnules membranaceous all petiolulate small obo- 

 vato-reniforra obliquely cuneate lobed glabrous dark green
