7. Stenochlaena Maxoni sp. nov. 



Climbing on tree-trunks. Rootstock wide-creeping, 8-10 

 mm. in diameter, densely covered with pale straw-colored, nar- 

 rowly lanceolate scales, which are usually less than I mm. wide ; 

 leaves scattered, 65 cm. or more long, on long, rather stout leaf- 

 stalks, 25 cm. long, which have scattering scales throughout like 

 those of the rootstock intermixed with brown fibrils which extend 

 upwards through the rachises ; pinnae about 9-jugate, distant, 

 rather long-stalked (5-7 mm.), acutely cuneate at the base, long- 

 acuminate at the apex, 12-14 cm. long, about 2 cm. wide, the 

 margins irregularly undulate, very slightly reflexed in drying ; 

 veins very prominent, converging in pairs at the base when simple, 

 occasionally forked, somewhat spaced, with about 8 intercostal 

 spaces to 1 cm. ; sporophyls 55 cm. or more long, with leaf-stalks 

 similar to those of the leaves, about 10-jugate, the pinnae distant, 

 stalked (4-6 mm.), obtuse at base, tapering at apex, 9 cm. long, 

 5-6 mm. wide. [Figures i i and 1 2.] 



Costa Rica: La Palma, alt. 1450-1550 m., Max on 411. 



It is with pleasure that we name this clearly marked species 

 from Costa Rica for Mr. William Ralph Maxon through whose 

 discriminating and careful field study we know so much of the real 

 characters of the fern flora of Costa Rica. The practice of sending 

 specialists into the field is of the greatest importance if we ever 

 expect to secure accurate information regarding the real characters 

 of plants. 



8. Stenochlaena Prieuriana (Fee). 



Lomariopsis Prieuriana Fee, Mem. Foug. 2 : 66. pi. 23. f. 



1845. 



Her 



Range : Known only from Guiana, Appun 128 (K) ; Pomeroon 

 River, Jenman ; Potaro River, Jenman ; Ragwa, Jenman. 



This species has been combined with Stenochlaena japurensis, 

 with which it has closest alliance ; its limited number of pinnae is 

 apparently a constant character, and until this is found to be due to 

 accidental causes it may best remain distinct as Fee left it.
