down, as Reseda lutea, f, 321, and 

 Lvia crispa (more properly undulata^) 

 Curt. Mag. t. 599. 

 Crispum,/, 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. cm. 931, 

 is an example of it, and may probably 

 be a variety of M. verticillata, Jacq, 

 Hort. Vind, v.l. t. 40. 

 Coneavimi, hollow, depressed in the middle, 

 owing to a tightness in the border, as 

 Cyamus Nehwibo, Exot. Bof. t. 32. 

 Vcnosffm,f. 88, veiny, v\^hen the vessels by 

 which the leaf is nourished are branched, 

 subdivided, and more or less prominent, 

 forming a network over either or both 

 its surfaces, as Cratagiis, or rather 

 Pyrus, torminalis, Engl. Bof. t. 298, 

 and Verhascum Lychnitis, t. 58. 

 Nervosum,/. 89? or costatum, ribbed, when 

 they extend in simple lines from the base 

 to the point, as mCypripedium Calccolus, 

 t. 1, the Convallarice, t. 279 and 280, 

 Straiiotes alismoides, EaoL Bot, t. 15,
