Cheilanthes — From the Greek; a lip, and a Jlower. Pteroides — Pteris-like. 



A RARE handsome species. 



An evergreen greenhouse Fern. 



Native of the Island of Java, where it is found at the 

 summit of Mount Gede, and also of the Cape of Good Hope, 

 at an elevation of from one to three thousand feet. 



Introduced into the Royal Gardens, Kew, in 1775. 



This species is so different in many respects to the genus 

 Cheilanthes, that it has been called an Adiantum by Linnaeus, 

 a Casseheera by Presl, and a Pteris by Houttuyn. However, 

 having the true involucres of a Cheilanthes, Sir William 

 Hooker has very properly placed it in that genus. 



Frond glabrous, large, and tripinnate; the pinnae remote; 

 pinnules remote, petiolulate, frequently an inch long, cordate.
