Lycofodium comflanatum L. 



Rhizomes extensively creeping along the surface of the ground 

 exposed or in moss, etc., usually green, flattened above furrowed 

 on the flattened surface, sparingly branchmg in the horizontal 

 plane spirally arranged or sometimes loosely segregated m whorls : 

 Uieir ielves lanceolate, acuminate, scarlous-tippcd the lateral ones 

 curving upward ; primary aerial shoots strong, flattened and fur- 

 rowed on one side, the branches convex on the upper side, concave 

 below (I 8-2.5 mm. broad), spreading out into a horizontal plane, 

 the medially placed branches more nearly terete, and either pro- 

 ducing additional foliage-bearing shoots or, ultimately, sporangium- 

 bearing peduncles : leaves of the vertical axes spirally placed or 

 in loose whorls, spreading, acuminate, scarious-tipped, the several 

 fq-SWows being reduced to four on the foliage branches ; the 

 leaves of the upper and lateral rows, which are separated as by a 

 continuous furrow, cuspidate, with spreading apices, bright green, 

 those of the under row reduced to slender, curved, spreading, cuspi- 

 date apices, the under side of the branchlets thus appearing devoid 

 of foliage, lighter in color and concave ; all the leaves decreasing 

 gradually in size from the base to the tips of the branches : pedun- 

 cles (5-75 cm. long up to the forking) terete, a little stouter than 



:;'/ 



second forks 2-5 mm. distant from each other : pedicels straight, 

 c-8 mm. (mostly 7-^ m^- ^""^O- bearing strobiles 1 5-25 mm. 

 lone. . leaies of the peduncles and pedicels scattered or loosely 

 whirled in threes, acuminate, scarious-tippcd, spreading : sporo- 

 phylls broadly ovate, more or less toothed on the lateral margins, 

 contracted gradually into a scarlous apex: sporangia reniform, 

 opening bv a transver.se slit: spores reticulate on the four faces, 

 ripening late in August and in September. (/". /, 4> 5, 7- 9' ^^>
