Rhizome short, erect, densely radicose; scales at the apex dense, lanceolate, 
hair-pointed, fusco-brown, iridescent; fronds fasciculated, dimorphous, sterile ones 
ovate, rounded or acute, 1-4 cm long on stipes 1-5 cm long, herbaceous, green; 
fertile ones lanceolate, longer-stipitate, apex generally elongate and rooting, base 
not auricled but narrowed gradually or shortly cuneate; venation sub-biseriately 
reticulated along the prominent midrib, free towards margin, green and glabrous, 
except the underside being sparcely glandular; sori elongate, 1- or irregularly 2- 
seriate along midrib, indusicwm membranaceous, gray, some opening towards, and 
some against, the midrib, and still others, towards each other as in Phyllitis; spores 
bilateral, echinose.

The chief interest of this peculiar-looking little fern lies in its remarkable 
walking ability, that is, its frond generally prolongates into an elongate whip- 
like viviparous tip, by means of which it spreads itself all about. The second 
species of the genus is C. rhizophyllus (L.) Link, of North America, which differs 
from our fern in larger size, deeply auriculato-cordate base of frond and 2-3 rows 
of sori on each side of midrib.
