 p. 189. P. concinnum, Mett. Kuhn Linn. SQ.p. 132. 



Hab. Venezuela, Fendkr, 212. Desvaux's plant thus named appears to be P. cultratum, 

 !rom which this differs by its distinctly separated pinnae, the largest more than an inch 

 long, narrowed gradually from the base to the point.

 adpre^sed scales ; St. 4-6 in. 1., wiry, slightly scaly ; fr. 6-12 in. 1., 2-3 in. br. ; 

 pinnae horizontal, bluntish, entire or slightly crenate, 2-3 lin. br., narrowed 

 towards both ends, the lowest not reduced ; texture subcoriaceous ; rachis wiry, 

 nearly naked ; under side with minute scattered scales ; veinlets obscure, forked ; 

 sori copious. Hk. Sp. 4. p. 212. 



Hab. Columbia and Ecuador. This comes near the next species, but is more slender, 

 with narrower distant pinnse and an ebeneous rachis. 



199. P. plebeium, Schlecht. ; rhizome stout, wide-creeping, clothed with small 

 grey scales ; st. 4-8 in. 1., strong, erect, castaneous, nearly naked ; fr. 6-12 in. 1., 

 3-6 in. br., ovate-deltoid ; cut down nearly or quite to the rachis into spreading 

 entire or obscurely crenated pinnae |- in. br., the lowest not reduced ; texture 

 subcoriaceous ; rachis and under side with small scattered scales ; veins obscure ; 

 sori copious. Hk. Sp. 4. p. 213. 



Hab. Mexico to Peru. Intermediate, as are the following species, in general habit 

 between pectinatum and vulgare. 



200. P. Hartwegianum, Hk. ; rhizome stout, wide-creeping, the scales linear, 

 dark-brown ; st. 4 in. 1., erect, naked ; fr. 1 ft. 1., 3^ in. br., cut down to the 

 rachis into linear-lanceolate obscurely crenated pinnce, J-f in. br., dilated at the 

 base, the lower ones distinct from the others, the lowest pair deflexed ; texture 

 papyraceo-herbaceous ; rachis slender, villose ; both sides slightly hairy ; veinlets 

 distinct, twice forked ; sori bright-yellow, oval, in two long rows. Hk. Sp. 4. 

 p. 207. Ic. t. 380. 



Hab. Mexico, Hartweg, 415. 



201. P. biauriculatum, Hk. ; st. 4-6 in. 1., stout, erect, villose upwards ; fr. 

 12-18 in. 1., 4-6 in. br. ; pinnce horizontal, 2 in. 1., J in. br., the edge entire, both 

 sides distinctly auricled at the base ; texture subcoriaceous ; rachis and both surfaces 

 densely pubescent ; veins immersed, indistinct ; sori filling up nearly the whole 

 space between edge and midrib. Hk. Ic, t. 121. 



Hab. Peru, Matthews. Placed by Moore in Goniophlebium. 



202. P. puberulum, Schlecht. ; rhizome wide-creeping, scaly ; st. 6-8 in. 1., firm, 

 naked, polished ; fr. 12-18 in. 1., 6-8 in. br. ; lower pinnce 3 in. 1., in. br., the 

 edge irregularly crenate, the base distinctly auricled on both sides ; texture 

 papyraceo-herbaceous ; rachis and veins beneath pubescent ; veins in slightly 

 pinnated groups, the main vein prominent ; sori in rows nearer the edge than 

 midrib. #. Sp. 4. p. 220. (in part). 



Hab. Mexico and Guatemala. Very near the last, but the position of the sori 

 different. 



203. P. subpetiolatum, Hk. ; rhizome stout, wide-creeping, densely clothed with 

 ferruginous lanceolate scales ; st. 4-6 in. 1., firm, stramineous ; fr. 1 ft. or more 1., 

 6-8 in. br. ; pinnce 3-4 in. 1., in. br., the point bluntish, the edge incon- 

 spicuously crenate, the lower ones rounded at the base, subpetiolate ; texture 

 papyraceo-herbaceous ; rachis and both sides finely villose ; veins subpinnate ; 

 sori in rows nearer the midrib than the edge. Hk. Sp. 4. p. 220.
