266 ASPLEMUM, § AMSOGONIUM. 



inches long subcoriaceo-niembranaceous ternate, lateral pin- 

 na3 alternate 1-3 inches long shortly petiolate dimidiato- 

 ovate acute erecto-patent, terminal one 4-5 inches long 

 ovato-lanceolate finely acuminate rather long-petiolate cu- 

 neate at the base all of them sharply serrated chiefly in their 

 upper half, veins oblique slender black fascicled 3-4 times 

 dichotomous lower superior ones generally anastomosing so 

 as to form a series of elongated areoles nearer the costa than 

 the margin, sori very long linear those of the veins that form 

 the areoles asplenioid meeting at the apex of the areole and 

 continuing diplazioid along the vein formed by the union of 

 the veins that constitute the areole, involucres (young) broad 

 membranaceous satiny. — Hook, in 2nd Cent, of Ferns, t. 51

Hal). Mexico, Dept. Oaxaca, Liebm. in Herb. Nostr. — This is a very peculiar- 

 looking plant, very uniform in the three fronds in my possession, and bearing 

 copious, though not very advanced sori. It is quite unlike any other Asplenium 

 with anastomosing venation. 



** Fronds pinnated, the less fully developed ones often simple. 



296. A. (Anisogonium) Knnzei, Mett. ; caudex short stout 

 erect, stipites 6-14 inches long stout and as Avell as the ra- 

 chis and costa and often the i)rimary veins beneath furfu- 

 raceo-paleaceous, fronds subcoriaceous blackish-green from 

 10-14 inches long or more subspathulato-elliptical acute 

 cuneate or attenuated at the base entire or irregularly and 

 acutely sublobate at the margin or broad ovato-truncate at 

 the base and variously sometimes deeply pinnatifid with a 

 subtriangular and acute entire apex or deltoideo-ovate and 

 pinnated in the lower half with two pairs of nearly opposite 

 sessile lateral pinnfe oblong 6-10 inches long 2 inches broad 

 shortly and rather bluntly acuminated truncated at the 

 base, the upper half or nearly so 8 inches long broad trian- 

 gular acute deeply pinnatifid with large horizontal segments 

 of the same shape as the pinnae, veins numerous horizon- 

 tally patent fascicled several times dichotomous copiously 

 anastomosing even from the base where they form large 

 costal areoles, sori diplazioid attached to all the veins conti- 

 nuous and anastomosing with them, involucres membrana- 

 ceous brown singularly crispato-undulate. — Metten. Asplen.
