(273 ) 
a single whorl at the upper sana probably exceeding the leaves in 
number, apparently early deciduous, se or oblong-ovate, when 
full-sized 3.5-8 mm. long, o. ee . wide : Eee gor ioina 
whorl, about 6-10 cm. long, containing 3-5 internodes; leaflets 
somewhat unequal, 2-5 mm. long, 0.5-0.6 mm. wide: antheridia 
m. wide; odspores 0.45 mm. long, 0.38 mm. wide; whorl 
of crown-cells 0.17 mm. high, 0.22 mm. wide at the base, the indi- 
vidual cells ovate, shortly and obtusely beaked. 
Type collected in Stafford County, Kansas, by M. A. Carleton, 
no. 302, July 11, 1891; inthe herbarium of the New York Botanical 
Garden. 
Distribution: Indiana to Iowa and Kans 
A very distinct species, probably meat to ve FHlornemannii, but 
at once distinguished by the absence of spine-cells from the mature 
internodes. In habit it greatly resembles C. odtusa Desv. = iVitel- 
lopsis stelligera (Bauer) Hy, or Zolypellopszs stelligera (Bauer) 
Mig., but lacks the starch-stars and is otherwise very different.

Monoecious : -8 cm. high, well incrusted; stems 0.38-0.53 
mm. in diameter, ements triply corticated, the cortical node-cells 
number of the leaves; spine-cells few, inconspicuous, when mature 
Oo. m. long, 0.05—0.1 mm. wide: stipulodes forming a single 
whorl at each node, twice the wees of oe TOvEs) 0.9-1.42 mm 
ee 0.1-0. oe mm. wide, acute at the a : leaves mostly 8 ina 
whorl, 5-8 long, entirely eae containing 2-4 a 
Mee teades 8, those at sterile nodes 0.7-0.9 mm. long, o.1- 
0.14 mm. wide, this often exceeding the diameter of the sippermont 
internodes of the leaves, as bracteoles much longer, sometimes ex- 
ceeding 2 mm., surpassing the mature sporocarps: antheridia 
.25-0. 28 mm. in diameter; mature sporocarps 0.6-0.65 mm. long, 
0.33-0.4 mm. wide; odspores oval, black, 0.44~0.4g mm. long 
0.28-0.33 mm. wide, with 2 some ewhat faint striae whorl of crown-

vidual cells ovate or nearly hemispheric, ei well separated at 
their tips
