12 ADIANTTJM LUCIDUM. 



The mite, ( Acarus tellarius,) or red spider, and A. holosericeus 

 are both very destructive, giving the leaves a scorched appear- 

 ance. Besides these, a large green caterpillar is so rapid in its 

 work of destruction, that if not removed, the fronds are soon 

 all eaten up; whilst several small beetles add their ravages to 

 the above pests of our hothouses, greenhouses, and gardens. 



Glabrous; fronds oblong-pinnate, the pinnae being alternate, 

 and attached by short petioles. Lanceolate, acuminate, coria- 

 ceous; the sterile serrated fronds being broadest. 



Stipes and rachis covered with ferruginous hairs. Rhizoma 

 creeping. 



The colour of the frond a bright olive green, and shining 

 both on the upper and under side; wedge-shaped at the base. 



Length of frond twelve inches. 



Sori linear, continuous, extending along both margins of the 

 frond to the apex. 



A stove Fern. 



An inhabitant of Tropical America, the West Indian Islands, 

 and Jamaica. 



I am indebted to Mr. Henderson, of Wentworth, for a plant 

 and fronds of this species. 



Not common in cultivation; it does not appear to be included 

 in any of the English Nurserymen's Catalogues. It is in that 

 of Messrs. Booth and Son, of Hamburg. 



The illustration is from a plant in my own collection.
