larly producing more or less orthotropic innovations the second and 

 sonietimes the third season, the lower and therefore older foliap 

 branches ultimately spreading and becoming ax, some of the 

 medially placed branches remaining short, thicker, terete strict y 

 vertical, and producing either additional foliage parts or ultimately 

 running up into strobile-bearing peduncles: leaves of the primary 

 aerial axis in 6-8 rows, those at the base of the shoot similar to 

 those of the rhizome, appressed, passing higher up the axis from 

 ovate through lanceolate-acute into the acuminate form ; those ot 

 the subterminal and terminal branchlets in four rows, an upper, an 

 under and two lateral, glaucous, bluish green, acuminate ap- 

 nressed those of the under row differing scarcely at all from those 

 of the other three rows, the leaves of the lateral rows somewha 

 incurved underneath, all becoming shorter and more crowded 

 towards the end of the season's growth : peduncles terete g aucous. 

 to-6o mm. long to the first forking, usually twice forked, the 

 second 8-18 mm. distant from the first, spreading and curving up- 

 ward the leaves on the peduncle and its branches spirally 

 scattered or less commonly loosely segregated into whorls of 

 threes, spreading-acuminate, scarious-tippcd ; strobiles two three 

 or usually four, 20-28 mm. long, the sporophylls broadly de- 

 pressed ovate, truncate at the base, the latera margins variously 

 toothed, suddenly contracted into a subuhite scanous tip, 

 sporangium reniform, opening by a transverse slit along the top , 

 spores deep yellow in mass, regularly areolate on the convex 

 face, the areolae on the triangular inner faces becoming larger 

 more irregular and fading away so as to leave a triangu ar smooth 

 area in the internal angle, ripening early m August..

The aerial parts reach a maximum height of about 22 cm. ex- 

 clusive of the spore-bearing parts which project an additional 

 height of 5-7 cm. above the general level of the foliage. The 

 color is liglit bluish green, and glaucous throughout except on the 

 aged lower branches, from which the waxy layer is worn away.

vertically placed branchlets. Newfane, Vt., July-August, 1899. 

 Specimens found later (Oct. 14, 1S99) by myself, on the hills near 

 Cold Spring Harbor. Long Lsland, N. Y.. which were growing in 

 the shade, and which were very much less vigorous than the Ver- 

 mont material, have looser foliage, the branchlets of which do not 

 stand vertically, though they do turn upward at the ends,, and the
