short, annulus 14-16-articulate, stoma narrow, spores ovoid." The figure repre- 

 sents the frond much more attenuated at each extremity, and with much smaller 

 sori. If it should eventually prove the same, the name of Mexicana must have 

 the right of priority. 



67. G. (Selliguea) caudiformis, Hook. ; caudex creeping 

 paleaceous with lanceolate-subulate ferruginous scales, sti- 

 pites remote piano-triquetrous a span or more long, fronds 

 dimorphous firm -coriaceous ; sterile ones 5-7 inches long 

 ovato-oblong acuminate acute at the base ; fertile ones 6-9 

 inches long elongated lanceolate more or less acuminate, ve- 

 nation obscure, primary veins costuliform ver)^ patent but 

 united by transverse veins including lesser areoles and then 

 having free veinlets, sori uniseriate between the costules sub- 

 rotund (and polypodioid) or confluent into linear elongate 

 (and grammitidoid) sometimes as long as the costules. — Var. 

 a, sori elongated and continuous. Grammitis (Selliguea)

 Fern have a great resemblance to those of our Polypodium (Phymatodes) irique- 

 trum, and are sometimes in like manner proliferous : but the fertile ones are nar- 

 rower and more or less acuminated. The sori are remarkable for being some- 

 times polypodioid and sometimes grammatidoid, so that it is difficult to say to 

 which group it should belong. 



68. G. (Selliguea) Feei, Hook. ; caudex creeping paleaceous 

 with subulato-setaceous scales which are dilated at the base, 

 stipites distant 2-4 or 6 inches long (of t\\Q fertile fronds), 

 fronds more or less firm-coriaceous glabrous; sterile ones 

 2—4—5 inches long ovate acuminate with an obtusely cuneate 

 base rarely and only when young oblongo-ovate and obtuse; 

 fertile ones 4-6 inches long lanceolate acvtminate (rarely ob- 

 long and obtuse) subdecurrently attenuated at the base, vena- 

 tion obscure, primary veins costuliform distant subhorizon- 

 tally patent united by transverse veins forming large areoles 

 which are again occupied l)y lesser areoles with or without 

 free included veinlets, sori central alternating with and pa- 

 rallel with the costules sunk, when young small and suborbi- 

 cular, in maturity nearly as long as the costules linear-oblong 

 pulvinate rarely subinterrupted. — Se\\\guea.,Bory,in Diet. Class.
