 alopecurum, but less robust, the branches more slender, the foliage 

 less complanate. Lower stem-leaves distant, squamose, more or less 

 triangulär. Middle stem-leaves sublinear, acuminate, concave, rather 

 laxe, erecto patent, incurved ; length 2,5 mm ; width at base . 65 — . 70 

 mm, at middle .45 — .50 mm. Margin plane, minutely serrulate below, 

 sharply and coarsely serrate above. Nerve thick and very broad, but 

 ill-defined, opaque, striate, gradually m erging into the lamina ; towards 

 the base flattened and dilated so as to occupy almost the whole width 

 of the leaf: narrowing upwards and becoming more prominent at back ; 

 vanishing below apex; width at base .55 — .60 mm, at middle .33 — .35 

 mm. Lamina at base very narrow , of 5—6 rows of elliptical cells. 

 Areolae oval, .03X.01mm; at apex of leaf larger, .035— .040X. 010 — .015 

 mm. Branch-leaves smaller, nerve narrower, about one-third width of 

 leaf; teeth larger. Neither fruit nor flowers yet observed. — Habitat :
