Cartilagineous, gristly; when the edge of the leaf 

 is strengthened by a tough 'border, the substance of 

 which differs from that of the leaf. 



Ciliate, lashed or fringed; when the margin is 

 surrounded on all sides with parallel bristles. 



Lacera, rent or ragged ; when they are variously 

 cut on the margin into unlike segments. 



Erose, gnawed ; when the leaf is sinuate, and has 

 other very small obtuse sinusses or hollows on its 

 margin. 



Integerrima, very entire ; when the outmost mar- 

 gin is entire, and quite free from notches. 



SUPERFICIES, Surface, is the outside, or what 

 covers the disk of the leaf, and respects both the 

 supine* disk or face of the leat, and prone disk or 

 back of it. Leaves, in respect to thtir surface, are, 



Viscid, clammy ; when they are smeared over 

 with a juice that is not fluid but tenacious, sticky. 



Tomentose, downy; when they are covered with 

 a nap of interwoven hairs, scarce perceptible, that 

 gives them a whiteness. 



Lanate, woolly ; when they are covered as it were 

 with a spider's web ; as in Salvia and Sideritis. 



Pilose, hairy ; when their surface is covered with 

 distinct hairs that ris,e to some length. 



Hirsute, rough with hair ; when they are hairy in 

 ji greater degree. 



Villose, shaggy ; when they are covered with a 

 coarser hair or shag. 



Hispid, rough ; when the disk is covered with a 

 stiffish sort of bristles that are frangible. 



Scabrous, rugged ; when the disk is covered witn 

 tubercles, little knobs. 



Aculeate, prickly ; when the disk is beset with 

 points that are sharp send stiff. 



* Supine is what lies on its Lack or face upwards; and 

 prone, the contrary : These terms are therefore well applied 

 to the upper and uuder disk or face of a leaf.
