 three unequal tubercles of the calyx. (Nut bony, l-cell* 

 ed with balsamy glands at the base.)

 ovate. 



CLASS XXII. CRYPTOGAMIA. 



ORDER I. FILICES. 



Ferfis aro annulated, when each capsule has a kin;! 

 ot'chahi passing around it at about right angles with the 

 suture. When the fruit is ripe, the chain in straitening 

 opens the capsule $ it being attached by its ends to two 

 contiguous edges of it. 



A. With annulated capsules. 

 1. Without involucres, 



Potypodium. Capsules disposed in round scattered 

 dots, on various parts of the lower surface of the frond. 

 2. With involucres. 



Onodea. Fruit-dots indeterminate, capsules covering 

 the whole lower surface of the frond ; involucre formed 

 by turning in or rolling back the margin of the leaf, which 

 opens inwards, in maturity, towards the midrib, or re- 

 mains closed. (The fertile leaves are contracted and nar- 

 rower than the barren ones,) 



Pteris. Capsules arranged in a continued line along 

 the very margin of the frond : involucre opening inwards. 

 (When the leaves are extremely small, the rows of cap- 

 sules on opposite sides meet and cover the lower surface 

 like the above.) 



Jlspteninm. Capsules in lines parallel to each other, 

 situated exactly upon the secondary veins of the frond : 

 involucres opening inwards. (By the secondary veins is 

 meant those of the middle part of the disk, not the larger 

 ones at the margin or midrib. The parallel lines of cap- 

 siilcs may stand obliquely with respect to the midribj but 

 their direction must be parallel to each other.)
