CINCINALls COLYSIS CYATHEA. 31 



the plants already in the country are comparatively small ; but 

 from the rapidity with which they grow they would seem to 

 rival those before named in the size to which they will ulti- 

 mately attain. They appear to be quite distinct and noble- 

 looking plants. 



CINCINALIS. 



Under this name we sometimes find three plants cultivated 

 in gardens which are here enumerated under the names of 

 Notlioclilana flavens, N. nivea, and N. tenera, by which they 

 are more generally known. 



COLYSIS. 



A genus containing only one species in cultivation. It was 

 formerly included under Drynaria, but was divided from that 

 group by Mr. J. Smith, of Kew. 



COLYSIS MEMBRANACEA (Membranous). This, which is 

 also sometimes called Pleopeltis membranacea, is a native of 

 the East Indies. The 'fronds are about 18 inches in length 

 and undivided. They are also thinner than in almost all 

 Ferns ; and, therefore, exhibit the arrangement of the veins 

 very beautifully. It has a creeping rhizome, and may, there- 

 fore, be increased by division.

CYATHEA. 



A tall-growing genus of Ferns, allied to DicTcsonia. In 

 their native habitats some of this species become trees 

 50 feet high, with a head of fronds at the top, giving them 

 a Palm-like appearance. The species in cultivation have been 

 lately introduced into British gardens, and consequently are 

 rare. 



CYATHEA AEBOEEA (Tree-like). In Jamaica, its native
