the middle, the margins strongly revohite, entire except at the min- 

 utely erose-dcnticnlate, acute or short-cuspidate apex ; costse medial, 

 ])ercurrent, the leaf in drying sharply carinate upon the upper surface, 

 the costs sometimes evident below near the base, but usually indi- 

 cated along the under surface of the leaf throughout merely by a 

 shallow medial furrow ; sporophyls conform, rarely more than 10 

 mm. long ; sporangia reniform, about 2 mm. broad, protruding beyond 

 the narrow bases of the sporophyls a distance of about 0.5 mm. on 

 each side. 



Type in the U. S. National Herbarium, no. 676073 ; collected from 

 a fallen branch in humid forest along the upper Caldera River, near 

 Camp I, Holcomb's trail, above El Boquete, Chiriqui, Panama, alti- 

 tude about 1650 meters, March 23, 191 1, by William R. Maxon (no. 

 5628). 



The specimens here described were found upon a large limb which 

 had been broken off from an enormous forest tree upon the steep 

 slopes above and partially obstructed the trail at a point not far above 

 Camp I. The species is very different from any reported previously 

 from North America, and from any vSouth American species known to 

 me. It is a coarse, " bushy " plant and, when in a fresh condition, very 

 heavy. Though not succulent it was long in drying, and then very 

 rigid. The arrangement of the leaves can scarcely be made out ex- 

 cept by soaking the plant in water, when the number of ranks of 

 leaves, the twisting of all but those of the tw^o upper rows, and the 

 reflexed position of the latter are features which become readily 

 apparent. Including the spreading leaves the diameter of the larger 

 stems is from 2.5 to 3 cm. The apparent abundance of leafy covering, 

 which has suggested the specific name, is even more pronounced in 

 the living than in the dried specimens. 



LYCOPODIUM STAMINEUM Maxon, sp. nov. 

 Plate 2 

 Plant about 20 cm. long, 3 times dichotomous (probably repeatedl\- 

 so in larger specimens), the stem relatively stout, about 1.5 mm. in 

 diameter at the base, i mm. in diameter near the apex, more or less 

 succulent, flattened in drying; leaves rather crowded in attachment, 

 borne apparently in 10 ranks, spreading at right angles to the stem, 

 filiform, acicular in the outer part, 10 to 17 mm. long, 0.2 to 0.3 mm. 

 broad, bright red at the base (at least upon the under side), the 

 margins entire and in drying curved inward over the upper surface, 

 the leaves thus broadly concave above or even subtubulose ; plant 

 fertile in the upper third, the sporangia borne in alternating zones,
