 phous ; but Dr. Klotzsch has ascertained that the P. salicifolium, Willd., is not 

 specifically different from P. Igcopodioides. The venation is not easily described, 

 nor do I find it to be by any means constant in what I consider to he one and 

 the same species. Included veinlets, that are free in some cases, in ntliers are 

 lengthened out and unite with the opposite side of the areoles ; this often hajipens 

 in the costular areole ; sometimes the free vcinlet has two divaricating branches, 

 or sometimes reflexed or even revolute blanches. Accurate figures alone can make 

 such venation intelligible to the student of Ferns. 



285. P. (Craspedaria) vacciniifolium, Fisch. and Langsd. ; 

 caudex long creeping or scandent branched clothed with 

 dense subulato-setaceous fibrillose scales, fronds distant sub- 

 coriaceous short stipitate of two kinds ; sterile short h an 

 inch to 2 inches long ^-^ an inch wide suborbicular or ellip- 

 tical very obtuse ; /er^i/e elongated 2-4 inches long ^ inch 

 broad linear obtuse, veins anastomosing forming large oblong 

 (suborbicular) oblique costal areoles including a free veinlet 

 bearing a sorus at the apex, marginal areoles few and exap- 

 pendiculate intermediate between the costa and the margin 

 slightly impressed. — Fisch. and Lavgsd. Fil. p. 8. t. 7 [very

 scales, sti[ntes ^-1 inch long, fronds subdimorphous both 

 kinds varying much in size but the fertile one generally 

 smaller than the sterile membranaceous subpellucid 2-4
