148 ASPLENIUM, § EUASPLENIUM. 



coloured scales, fronds submembranaceous opaque scarcely 

 more than an inch and a half long lanceolate pinnated, pinnie 

 Ij line long at the utmost ol)liquely rhombeo-cuneate sessile 

 irregularly dentato-incised teeth obtuse, 3 or 4 of the termi- 

 nal confluent into a pinnatifid terminal lobe, veins forked, 

 sori . . . ? (Tab. CLXXX. B.) 



Hab. Madagascar, Dr. Li/all. — This is, I think, the smallest of the Ferns (save 

 in Ilijmpnophyllaceoe) with which I am acquainted, and is evidently allied to the 

 A. Krait.ssii ; ditfering, however, remarkably in the thicker and darker-coloured 

 frond, narrower and less cuneate or flabellate pinnae, which have blunter teeth, 

 but especially in the long, setiform, spreading, dark-coloured scales of the stipes 

 and rachis. My only s|)ecimen (here figured) is unfortunately attached to the 

 paper with the under side downwards, aiul I am unwilling to destroy my specimen 

 for the chance of being able to detect the sori. There can scarcely be a question 

 of its genus, and as little of its specific distinction. 



112. A. (Euaspleniuni) jjrojectiim, Kze. ; caudex slender 

 filiform creeping amongst mosses, stipites scattered i-f of 

 an inch long and as well as the rachis extremely slender fili- 

 form here and there rooting and at the apex proliferous, 

 fronds prostrate spreading 2 inches long thin- membrana- 

 ceous 1-2 line wide linear-lanceolate acuminate, pinnae on a 

 very short black petiole 12-16 horizontal scarcely \ a line 

 broad trapezoideo-orbicular with an obsolete lobe or auricle 

 on the base above, veins short forked or rarely twice forked 

 scarcely extending beyond the centre of the pinna, sori 

 oblong 2-3 on each pinna, involucre white membranaceous. 

 (Tab. CLXXXI. A.) 



Hab. AVarm rocks, Pompayaca, Peru, Pceppig. — If I have mentioned our Aspl. 

 pygrtKeum as among the smallest of Ferns ; this is unquestionably among the most 

 delicate, more resembling at first sight a Jungermannia than a Fern. My speci- 

 mens are authentic, being named by Kunze himself: and it does not appear that 

 the plant has been met with by any traveller, save Dr. Pceppig. 



(Furcatum-^rrow;?. — Type Aspl. furcatum, Th., or A. falcatum. Lam., among the 

 simply pinnated species. — Pinnate or bi-tripinnate. i\onds often large more 

 or less compound rigid suhcoriaceous frequently turning brown when dry. 

 Veins frequently close and parallel, giving a striated appearance; pinnm and 

 pinnules approaching to rhomboid or cuneate, generally eroso-dentate ; vhen 

 simply 2>init ate with rather large pinnce approaching the Salicifoliuni-^^/o'i/;.) 



Pinnate. 

 113. A. (Euasplenium) longissimum, Bl. ; caudex stout 

 woody paleaceous with rather long brown lanceolato-subu- 

 late scales, stipites and rachis dark lurid-black deciduously 

 villoso-paleaceous, fronds very variable in length 1-3 and 

 more feet elongato-oblong-lanceolate suhcoriaceous opaque
