8 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



to an attenuate base, but at last abruptly euneate; this last is one of the most dis- 

 tinctive marks of the species. In C. tenuipes the base of the lamina is evenly acute or 

 acuminate to the end. In general leaf form and in its long slender stipes only, C. 

 tenuipes resembles C. sphenodes, as understood by Doctor Christ, very closely; but 

 from this it differs radically in venation and wholly in the characters of its rhizome, 

 C. sphenodes having the areoles not divided by a secondary veinlet and the rhizome 

 very slight (less than 2 mm. in diameter), sinuous and extensively creeping or climb- 

 ing, essentially naked, and with the fronds widely spaced. 



Campyloneurum xalapense Fee. 



II. 1857. Coban, altitude 1,350 meters, June, 1907. 



Goniophlebium acuminatum Fee, lime Mem. Foug. 68. pi. 19. f. 1. 1866.

The specimen referred here agrees well with Fee's plate and description. The tissue, 

 though coriaceous, is uncommonly translucent; the veins are elevated. Known pre- 

 viously to the writer only from the West Indies, Guadeloupe, the type locality, and 

 Jamaica (Maxon 1022, 1918).

Known only from Guatemala, where it is not uncommon; usually listed under the 

 invalid name PoJypodium guatemalense Hook. If retained under Poly podium, Chris- 

 tensen's name must be adopted. The venation is peculiar and is illustrated by 

 Moore, plate 58, figure 4. The plant is essentially a Goniophlebium, however; and 

 Moore'H name, though invalid under Polypodium, is available under the genus 

 Goniophlebium. 



Goniophlebium loriceum (L.) J. Sm.

Goniophlebium sanctae-rosae Maxon, sp. nov. 



Fronds several, close or scarcely 1 cm. apart, rigidly erect, 25 to 65 cm. long; rhizome 

 very firm, short-creeping, prostrate, copiously rooting below, 5 or 6 mm. in diameter, 

 the fronds borne upon very pronounced knob-like protuberances 3 to 4 mm. high, 

 the whole rhizome very closely covered with persistent wholly appressed roundish 

 or subovate dark rusty scales less than 1 mm. long, these attached at their large 

 blackish centers, Ihe lighter margins delicately and minutely fimbriate; stipes stout, 

 2 to 3 mm. in diameter, 8 to 28 cm. long, dark or light brown beneath a dense chaffy 

 covering similar to that of the rhizome, the scales longer, often long-attenuate, copi- 

 ously, deeply, and evenly fimbriate, the cilia approximate and wide-spreading; 

 lamina 17 to 35 cm. long, 5.5 to 15 cm. broad, oblong to broadly oblong-lanceolate, 

 not reduced at the base, the apex usually very abruptly reduced with a conform or 

 elongate terminal pinna, or, rarely, gradually reduced, the uppermost pinna; 1 to 1 .5 

 cm. long, the terminal segment nearly equal; rachis clothed below like the stipe, the 

 scales mostly long-attenuate; pinna? 14 to 38 pairs, straight, horizontal or slightly 

 ascending, linear, entire, 2.5 to 8 cm. long, 5 to 7 mm. broad (appearing narrower 

 from the narrowly involute margins), slightly dilatate at 1he base, mostly a little 

 Biircurrent, the upper ones also decurrenl , their bases adjoining, the lower ones disr 

 tinct; up to 1 cm. apart, their bases unequal, invariably surcurrent, horizontally
