 have given above, with A.fragrans, Sw., and its allies. 



166. A. (Euasplenium) scandlcinum, Klfs. ; caudex erect or 

 declined stout sparingly paleaceous, stipites tufted a span to 

 nearly a foot long brownish-green, fronds a foot and more 

 longcoriaceo-membranaceous somewhat glossy broad-lanceo-

 obtuse obscurely auricled at the superior base \ an inch long 

 strongly serrated at the apex and on the superior margin, 

 ultimate ones of the pinnae confluent into a deeply serrated 

 acumen, veins subfiabellate, sori solitary rarely 2 on a pin- 

 nule pulvinate, involucre small whitish soon concealed by 

 the capsules of the sorus. (Tab. CCIV.) — Klfs. En. Fil. p.

 — This is probably a rare plant ; I have seen only the specimen from Herb. Reg. 

 BeroUnense, from which onr figure and description are made, and one from Mr. 

 Tweedie, both from South Brazil. It seems very distinct, and is remarkable for 

 the usually solitary and large sorus on the pinnule. I quote Mettenius with a 

 mark of doubt, because his description does not accord sufficiently with my plant, 

 and because he includes Gardner's n. 17B, which is undoubtedly Asp. adianiioidex, 

 Raddi.
