llab. Tropical America, most abundant, from Brazil to tlie West Indies and 

 Mexico, and Ecuador and I'eru. — A most common American species, and, as may 

 be expected, liable to considerable variation in tbe length and breadth of the 

 frond, and in the greater or less number of sori in each series. The species is 

 otiierwise an unmistakable one. Some of tiie specimens vie with the noble 

 Aspleniam iViclus in size and beauty; others, especially from Peru, are so narrow 

 as to justify the specific name of Vittaria. 



335. P. (Phymatodes) cras.nnerviuin, Bl. ; caudex very 

 stout creeping tortuou-s with many short branches which are 

 setose with l()n!^-sul)uUite falcate scales, stipites remote seta- 

 ceo-squamose 4-6 inches long stout, fronds 1-H foot long 

 2-1 inches broad glabrous very firm and hard thick-co- 

 riaceous oblong or subovato-lanceolate acuminate cuneato- 

 attenuate at the base the margin callose and thickened ob- 

 scurely remotely subcrenate, costa very broad flat and pro- 

 minent, costules very stout and prominent, veins sunk and 

 quite obscure, sori almost universal arranged in a single series 

 between the costules and sunk in cavities which form pus- 

 tules on the upper side. — Bl. Fil. Jav. p. 145. /. 61. Metlcn.

Hah. Java, Blame, Zolliitger, De J'riese and Teijsmann, n. 3, Tho.i. Lobb. — A 

 peculiar species, the analogue of the South American P. crassi/olium. I.., but 

 far more coriaceous in texture, and remarkable for the great regulariiy of the 

 fructifications ; the under side is quite tessellated, if I may so say, by the cavities 

 of fructifications, while the upper side is tessellated with the embossments. 



336. P. (Phymatodes) trhpietrum, Bl. ; caudex stout long 

 creeping or scandent clothed with appressed closely imbri- 

 cated large silky pale-tawny ovate very obtuse scales, stipites 

 remote 4-6-8 inches long, fronds subdimorphous very thick 

 firm coriaceous entire scarcely incrassatcd at the margin 6-9 

 inches long; sterile ones 3-4 inches broad ovate or ovato- 

 lanceolatc acuminate obtuse or cuneate at the ha.se; fcri He 

 ones generally longer and narrower obloiigo-lanceolate acumi- 

 nate cuneato-attenuate at the i)ase, costules very distant pro- 

 minent beneath, venation obscure but resembling that of /-*. 

 siuatile, sori large biseriatc between the costules 6-8 in each 

 series.— fi/. Fil. Jav. p. 141. t. 59. Metten. Polyp, p. 116./. 3.
