PLATE II. 

 Cheilanthes amaurorachis, Kunze. 



Hypolepis — From hypo — under, and lepis — a scale. AmauroracJiis- 



Dark raohia. 



A GREENHOUSE Specics. 



Native of New Holland. 



The- fronds, which are membranaceous and very hairy, are 

 ovate-acuminate, hi- or tri-pinnato-pinnatifid, being less divided 

 near the apex. The pinnse petiolate, the basal ones opposite. 

 The pinnules, primary ones decurrent and oblong-obtuse, the 

 secondary ones sinuato-incised. 



Rachis and stipes purplish, rough, and very hirsute. 



Rhizoma creeping. 



Sori marginal, small, and sub-globose in form, situated in the 

 sinus of the lobes. 



Veinlets forked and free. 



A plant easily managed, and speedily making a pretty speci- 

 men with ordinary care, as the fast creeping rhizoma soon spreads 

 itself in all directions. 



For a plant my thanks are due to Messrs. Booth, of Ham- 

 burg; and for fronds to Mr. R. Sim, of Foot's Cray, Kent.
