polygonal-oblong, cuticle smooth: underleaves distant, somewhat 
broader than stem, broadly ovate, deeply bifid about three fourths, 
the lobes triangular, acute, parallel or spreading, 6 to 8 cells broad, 
8 to 12 cells long ; sinus separating lobes acute or obtuse ; cells of 
underleaves similar to those of leaves. 
Stems 0.25™" to 0.38™™ in breadth; leaves 1.05™"x0.9™™ ; leaf-cells 
at apex 33y, at base 62ux35y; underleaves 0.47"x0.45™™ ; cells at 
middle of lobe of underleaf 62yx35p.

Kantia cuspidata is a smaller plant. than A. Zosana. The leaves 
are cuspidate or obtuse, never bidentulate ; the underleaves are more 
deeply bifid, and their lobes are never truncate or bilobed.

Autoicous : plants small, scattered, pale green: stems pale green, 
slender, weak, prostrate, ascending at the tip, often gemmiparous, 
rarely branching except at the base, attenuate or blunt, oval in sec- 
tion, about 7 by 5 cells, ventral surface more convex than the 
dorsal, cortical cells (in about 12 rows) subquadrate, thin-walled, 
dorsal cells slightly larger than ventral, interior cells polygonal, thin- 
walled ; a row of large elongated cells is found on each side of the 
stem where the bases of the leaves are attached ; branches similar to 
stem, more often attenuate ; rhizoids borne in clusters at the base of 
the underleaves: leaves tender, alternate, spreading, obliquely 
inserted, imbricated or approximate, becoming distant on atten- 
uated stems or branches, decurrent postically to about the middle of 
the next leaf, antical base arching halfway over the stem, broadly 
ovate, apex truncate-bifurcate or bidentulate, lobes spreading, tri- 
angular, acuminate, 1 or 2 cells broad, 3 or 4 cells long, ending in a 
row of 2 or 3 cells; sinus separating teeth lunate: leaf-cells at 
apex subquadrate with slightly thickened walls, at middle of base 
oblong-polygonal with thin walls, at margin elongated, with slightly 
thicker walls than interior cells: underleaves distant, minute, deeply 
bifid to within a single cell of the base, which is 5 or 6 cells broad, 
each lobe bearing a single tooth on its outer margin, spreading, 
subulate, 2 cells broad, 4 or 5 cells long, ending ina row of 3 or 4 
cells, the lateral tooth composed of 1 or 2 cells; underleaf-cells 
with slightly thickened walls: ¢ and @ flowers borne on very short
