polyphylla and C. trichacantha, and are here doubtfully assigned to 
the former. They may not unlikely prove different from both. 
C. hattensts is well represented by Nash & Taylor, no. 7470, 
San Michel to Marmelade, Haiti, August 6, 1905.

Monoecious, the antheridia and odgonia borne upon the same leaf- 
nodes, the lowest at that between the lowest and second of the corti- 
cated leaf-internodes : 15-50 cm. high, light- or bluish-green, moder- 
ately incrusted; stems 0.63-1.5 mm. in diameter, triply corticated ; 
spine-cells 0.3—-1.5 mm eee stipulodes dace a double whorl at 
each node, those in the upper whorl 0.7-0.82 mm. long, equaling 
or exceeding the uncorticated basal ia ener stipulodes of 
ower whorl 0.44-0.62 mm. long: leaves 11-14 in a whorl, 1-2 
cm. long, containing 9-12 eee. all triply corticated, except 
the uncorticated basal one and the leaf-tip, which also is uncorti- 
cated, the uncorticated basal internode Ae 14 times as long as wide 
leaflets at sterile nodes 0.16-0.23 mm. long, those at the lowest leaf. 
node ventricose, different from those at succeeding nodes, as brac- 
0.23 mm 
long: antheridia 0.35-0.4 mm. in diameter; sporocarps 1.1-1.24 
mm. long; odspores 0.72-0.78 mm. long, 0.48-0.54 mm. wide, 
with somewhat connivent crown-cells. 
Type locality: Caracas, Venezuela. 
Distribution: Texas to South America. 
The measurements given above are taken in part from Braun’s 
descriptions, partly from Miller zo. 354, Orizaba, Mexico. Plants 
more or less referable here have been collected from as far north 
as Lake Erie. They are probably better placed with C. haztensis, 
and may be distinct from both. No South American material of 
this species has been available for examination.
