Hab. Mexico and the northern parts of tropical S. America. The following 

 localities are from my herhariuni : — Mexico, Linden, n. 1551 and 1552 (small, 

 tripliyllous, but fertile) ; Gakotti, n. 6243 (with twenty-one oblong-lanceolate 

 pinnae), Go54, Dr. Coulter, n. 1712 and 1713, Liebmann (Phanerophlebia nobi- 

 lis); Guatemala, Skinner, one specimen with ])inna3 10 inches long; Caraccas, 

 Linden, n. 1G4, Birschel, and ex Herb. Miquel, n. 201, Otto, n. 644 ; Venezuela, 

 Funck, n. 211, Fendler, n. 233. — Ever since I possessed sufficiently copious spe- 

 cimens of this plant, I have in vain endeavoured to detect any character which 

 can justify their being separated into species ; nor do any descriptions and figures 

 I have seen, appear to me to warrant such a conclusion. It is quite certain that, 

 as in others of this group, the venation is variable, often on one and the same 

 plant. The error was perhai)s encouraged by Presl's placing them in two dif- 

 ferent genera in his Tentamen. Ilis genus Amblia is the same as Phanerophlebia, 

 the involucres having fallen from the latter. 



48. A. (Cyrtomium) caducum,V^Q[\.', caudex suberect stout, 

 stipites a foot and more long stramineous very paleaceous 

 with black large lanceolate scales below with a brown edge 

 above these are broader membranaceous lax brown ones, 

 fronds coriaceous 1-1 \ foot long broad-lanceolate acuminate 

 pinnated (or subbipinnate), pinnte numerous 3-5 inches long 

 h an inch to an inch wide falcato-lanceolate acuminated un- 

 equally so at the base, superior base truncated and dilated 

 with a more or less distinct obtuse or acute auricle acutely 

 subaristato-serrated not unfrequently lobato-pinnatifid and 

 in some inferior pinnae quite pinnated with obovate rather 

 obtuse pinnules, veins copious approximate erecto-patent 

 pinnate free or with the veinlets more or less combined 

 forming elongated arcoles generally including a long free 

 veinlet and sometimes the whole frond is bipinnate and the 

 veinlets are then always free, and the plant has no very 

 distant resemblance to some forms of Aspid. (Polystichum) 

 aculeatum, sori large scattered, involucres very conspicuous 

 orbicular peltate but sometimes with a small sinus. — Hull.
