ADIANTUM. 39 



Hab. Brazil, Selloiv (Klotzsch in Herb, nostr.) — The specimen I iini 

 favoured with of this rcniaikahle pUiiit, consists of a stipes ahoiit a foot 

 lonfx, heavino- the iiase of a frond about 5 inches in length, showing a ranii- 

 fiation similar to ihat of A. Capillus-Veneris, but with longer petiolules 

 standing out at right angles from the secondary or tertiary rachis, the 

 pinnules about as large as in the species just mentioned, but of a totally 

 different shape, almost resembling the leaves of Geranium disserliitn, and 

 nearly, if not quite, equilateral, and so unlike those of any Adianlwii 

 that it will be seen that Willdenow had considered it a L'jijodium. In 

 the absence of fructidcalion I can give no opinion of the true genus ; and 

 as neither Presl nor Klotzsch has, as far as I know, given anything but 

 the name of this plant, I cannot say if they had the means of determining 

 accurately the proper genus. 



79. A. emarginatum, Bory ; "fronds bi- (tii-) pinnate, 

 pinnules obcordato-cuneate, sterile ones serrulated at the 

 apex, sori oblong." Willd. — Bori/ in Willd. Sp. PI. v. p. 449. 

 —&. pinnules larger. (Tab. LXXV. A.)

 Herb, nostr. n. 135. Malacca, Griffith. — From Bourbon I possess a spe- 

 cimen under this name, uiven me, with many other fine things, by the late 

 lamented M. Benj. De Lessert, and which sufficiently accords with Will- 

 denow's brief character and remarks. It has quite the habit of rather 

 large-pinnuled specimens of ^. Ai!thiopici(m, but with sori resembling both 

 as to position and form those of yl. CapiUus-Veneris ; hence thejust remark 

 of Willdenow " valde simile praecedenti sed statura constanter minor, pin- 

 nulse nunquam lobatae semper obcordatse.'' Dr. Wi;^ht's specimen, 1. c, 

 quite accords with the Bourbon plant; except that the pinnules are again 

 rather larger (all bearing fructification). Mr. Griffith's specimen from Ma- 

 lacca precisely agrees w-ith Dr. Wight's Adiantuin, and being only partially 

 fertile the serrulated apices are very apparent. But in all these I see 

 nothing to distinguish them from the South American A. Chilense. The 

 specific name is vgry incorrect ; for Willdenow savs " pinnule apici pro- 

 funde emarginalEB majores obcordat8B,lobis quandoque /ewto- emarginatis." 

 We need not tell any one accustomed to study ferns, how variable is the 

 lobing of the pinnte and pinnules on one and the same specimen. 



80. A. cuneatum, Langsd. and Fisch. ; frond rather small 

 ovate or oblong-ovate triquadripinnate, pinnules membrana- 

 ceous glabrous on rather long slender petiolules cuneate (more 

 or less broadly) superior margin rounded conspicuously 2 — 4- 

 lobed, lobes obtuse deeply euiarginate or bifid, their segments 

 falcately incurved connivent, sinus or narrow deep cleft of each 

 lobe soriferous, sori rather large, involucres orbicular-cordate 

 membranaceous, stipes and slender rachis everywhere ebene- 

 ous glossy glabrous. Langsd. and Finch. Ic. Fil. Brasif.
