(1) C. cordifolia (Blunie) J. Sm. Stipes clustered, 20 cm. long, firm, 

 erect, scaly below; frond 30 cm. long, 10 cm. broad, entire, cordate, acu- 

 minate, coriaceous; veins in close groups of about 4, anastomosing copiously

Although Presl separates this plant as the genus Ochlogramme from the 

 neighboring two, it is too near them for easy specific separation by the 

 descriptions.

(4) C. pariens Copeland. Caudex black, clothed with lanceolate, dark 

 brown paleae 8 mm. long; stipe channeled, about 35 cm. high, black 

 and somewhat scaly at the base, like the rachis above, green and clothed 

 with very minute fibrils; pinnae in the type 11 pairs, those of the lower 

 half of the frond larger, 10 cm. long, 4 cm. broad, ovate, acuminate, 

 base rovmded, short stalked, entire, subcoriaceous, glabrous; terminal 

 pinna like the lateral; upper axils bearing bulbils which grow into 

 yoimg plants before falling; veins once or twice forked, anastomosing 

 and indistinct in the marginal third of the blade; sori linear, straight, 

 extending as far as the veins are distinct.
