 forming two irregular series of oblong large areolcs, sori very

Hab. "Ecuador, on a tree by the river-side, near Archidona (124 m. N.E. of 

 Quito) ; the plants were partially immersed in water, and to the root or caiidex 

 were attached hollow succulent tubers, in which the ants had taken refuge," 

 Jameson, n. 789. — I know nothing like this very distinct and remarkable Fern, 

 which has only been detected in the locality above mentioned. All my specimens 

 are quite uniform. 



366. p. (Phymatodes) lomarioides, Kze. ; caudex creeping 

 constituting a stout probably when recent spongy mass 2-3 

 inches and more thick bullatc Avith large swellings on the 

 surface and conical processes on which the stipites are 

 jointed, the whole tessellated as it were and silvery-grey with 

 a coating of small peltate scales which have a dark spot in 

 the centre, stipites subaggregate 2-4 inches long, fronds di- 

 morphous coriaceous deeply pinnatifid ; sterile fronds 6-14 

 inches long broad-oblong deeply but not to the rachis pinna- 

 tifid, segments 5-17 pairs 2 rarely 3 inches long f-1 inch 

 wide oblong very obtuse often dilated upwards and truncate, 

 venation distinct, costules veniform uniting not far from the 

 margin so as to form a large primary areole (which in the 

 contracted fertile frond includes the sorus), the rest of the 

 venation forms irregular copious oblong areoles which in- 

 clude copious free and divaricating close-placed veinlets ; 

 fertile fronds 1-H foot long oblong 4-5 inches wide pinna- 

 tifid nearly to the rachis (below almost pinnated) with 20-30 

 or more broad linear obtuse or truncated segments, sori large 

 quite sunk in a cavity represented by tubercles on the other 

 side oval forming a single series between the costule and 

 margin. — Kze. in Metten. Folyp. p. 102. Drynaria, J. Sm.

 — Notwithstanding the striking difference between the fronds of this remarkable 

 plant and those of P. simtosu77i. Wall, (our n. 332), I am disposed to think, from the 

 nature of the caiulex and the venation, that these two may prove not specifically 

 different. On mentioning to Mr. J. Smith my views regarding the unity of these 

 two very distinct-looking Ferns, he not only was disjiosed to agree with me, but 

 suggested that another Fern, viz. Lecav.opteris carnosa, lil., universally looked 

 ui)on as a distinct genus, was equally an abnormal form of our present Polypodinm ;
