16 SURFACE OF LEAVES. 



Repandum, f. 84, wavy, bordered with numerous 

 minute angles, and small segments of circles al- 

 ternately, as Menyanthes nymphceoides, t. 217, 

 and Inula dy sent erica, t. 1115. 



Glandulosum, glandular, as Hypericum montanum, 

 t. 371, and the Bay-leaved Willow, Sallv pen- 

 tandra. 



Revolution, revolute, when the margin is turned or 

 rolled backwards, as Andromeda poll folia, .713, 

 and Tetratheca glandulosa, Exot. Bot. t. 21. 



Linnaeus seems originally to have applied this 

 term to the rolling of the whole leaf backwards, 

 as in Solid ago Virgaurea y Engl. Bot. t. 301, 

 meaning to use the expression marglne revolution 

 when the margin was intended ; but this latter 

 case -being extremely frequent and the other very 

 rare, he fell into the practice of using revolutum 

 simply for the margin. 



Involutum, involute,, the reverse of the preceding, 

 as in Pinguicula, t. 70 and 145. 



Conduplicatum, folded, when the margins are brought 

 together in a parallel direction, as in Roscoea 

 purpurea, E.vot. Bot. t. 108. 



7. Terms expressive of different kinds of Surface, ap- 

 plying equally to the leaf and to the stem, have 

 been already explained, p. 96\ To these may be 

 added the following, chiefly appropriated to leaves. 

 Punctatum, dotted ; either superficially as in Rho-
