142 ASPLEXIUM. § EUASPLENIUM. 



(occasionally bearing an axillary branch from a scaly bud), 

 chartaceous linear elongate flexuose, probably procumbent, 

 pinnated, pinnre distant sessile 3-4 lines long often oppo- 

 site oval or broad oval very obtuse entire or only obscurely 

 sinuate, the sides equal (in no way dimidiate), costa central, 

 veins few remote simple clavate at the apex a little distant 

 from the sori few irregular oblique oblong small, involucre 

 thin membranaceous. — Fee, ^me Mem. Foug. p. 51. t. 13.

Hab. Andes of Peru, Mathews, 1835 (in Herb. Nostr.). N. Granada, moist 

 grottoes in forests of Ocana, clev. 7000 feet, Schlim, 1846-52. — A very remark- 

 able and distinct species, two and probably three feet long, with two narrow 

 fringed lines on the ebeneous stipes and rachis, reminding one of those on the 

 stems of Veronica Chamcedrys, but less conspicuous. Our specimens from Peru 

 arc the largest, and subcoriaceous. The singular scaly buds on the rachis, 

 which throw out a young plant (no roots), and seem to form a branch, are 

 analogous to what we have noticed as described by Brackenridge on the stipes of 

 Aspl. monanthemum in the Sandwich Islands. 



101. A. (Euasplenium) arcuatum, Liebm.; "fronds ceespi- 

 tose herbaceous very glabrous 6-9 inches long (stipes scarcely 

 an inch long) linear-lanceolate towards the apex gracefully 

 arcuate pinnated attenuated at each extremity, pinnre 4 lines 

 long 2 lines wide sessile densely imbricated horizontal or 

 slightly deflexed alternate subparallelogram, anterior base 

 straight entire, superior truncated straight roundish obtuse 

 obtusely sinuate, superior margin repand, veins conspicuous 

 clavate at the apex terminating within the margin, sori 2 

 close to the inferior margin parallel and imbricating, stipes 

 and rachis filiform elastic arcuate very black shining plane 

 above convex beneath." (Tab. Cl^XXXlX.)— Liebm. Fil.

Hab. Mexico, Sartorius, "Liebm.," n. 28, Karwinsky (Mettenius), Galeotti, 

 n. 644G, in part {Fee, the same number is referred to by Fee for his Aspl. 

 leptopJn/llum, — our A. monaiitliemum). Rocks in Vera Cruz, elev. 2000 feet, 

 Galeotti, n. G299, very scarce; Rincoii-faisan, Vera Cruz, Linden, n. G9. — I have 

 seen no authentic specimen of this plant, but I take a Mexican Asplenitim of 

 Galeotti, n. 0299, and of Linden, n. 09, to be identical with it, corresponding 

 with the characters given by Liebmann and by Mettenius, sutRciently so to 

 justify me in taking my figures from those specimens. In general aspect and 

 appearance the species is very striking, and though there are slight ditfer- 

 ences in the more or less entire margins of the jjinnne, yet the specimens 

 gathered by the respective collectors are all identical — the same very short 

 stipites, the same yellow-brown colour of the frond, its linear-oblong form, the 

 close compact, almost exactly parallelogram, very obtuse pinna-, scarcely at all 

 aiiricled, tlie costa occupying nearly the middle of the pinna; in consequence of
