SURFACE OF LEAVES. 127 



dodendrum punctatum, A?ub\ Repos, t. 36, and 

 Mdaleaca UnarifoUa, Exot, Bot, t, 56; or through 

 the substance, disin Hjjpericum perforatum, Engl. 

 Bot. t. 9.95, and the natural order to wliich the 

 Orange and Lemon belong. 



Rugosum, rugged, when the veins are tighter than 

 the surface between them, causing the latter to 

 swell into little inequalities, as in various species 

 of Sage, Salvia. See Flora Grceca ; also Tell- 

 er ium Scorodonia, Engl. Bot, t. 1543. 



Bullatum, blistery, is only a greater degree of the 

 last, as in the Garden Cabbage, Brassica oleracea, 



Piwatum, f. 85, plaited, when the disk of the leaf, 

 espt-cially towards the margin, is acutely folded 

 up and down, as in Mallows, and Alchemilla 

 vulgaris, Engl. Bot. t. 597, where, however, the 

 character is but obscurely expressed. 



Undulatum, J. 8G, undulated, when the disk near 

 the margin is waved obtusely up and down, as 

 Reseda liitea, t. 321, and Lvia crispa (move pvo- 

 perly loidulata*) Curt. Mag, t. 599. 



CrispuniyJ] 87, curled, when the border of the leaf 

 becomes more expanded than the disk, so as to 

 grow elegantly curled and twisted, which Linnaeus 

 considers as a disease. Malva crispa, Ger. em. 

 931, is an example of it, and may probably be a 

 variety of M, verticillata, Jacq. Hort. Vind. 

 v.\.t. 40.
