 for it must be observed, that integr-wn

 posed to inerme ; ciliatnm, fringed with 

 soft hairs ; cartiluginewn . hard and horny ; 

 dentatum, toothed ; serratnm. serrated, the 

 teeth like those of a saw, pointing for- 

 wards, serritlaturn, minutely serra'ed ;

 curle'd and twisted, which is generally 

 a preternatural luxuriance ; concavwn, 

 hollow in the middle? venosum t ve : ny; 

 nervoswn, ribbed, the principal veins or 

 ribs extending in simple lines from the 

 base to the point ; aveniiim, without v . uis ; 

 enerve, without ribs : triiterve> three-rib- 

 bed ; triplinerve, triply -rib bed, win v. the 

 lateral ribs branch off' above the base ; 

 basi trinerve, when the base is cut away 

 close to the lateral ribs, as in burdock. 



A few other terms relating to leaves in 

 general deserve mention F. carnosum is 

 a fleshy leaf, such as belongs to those 

 called succulent plants The internal 

 pulp of these seems to have no share in 

 their peculiar functions as leaves; but to 

 be a reservoir of moisture, and some de- 

 gree of vitality. F. nndum means a leaf 

 destitute of all clothing or hairiness what- 

 ever : the same term applied'to a stem, 

 means that it bears no leaves, and to a 

 flower, that it has no calyx. F. tubuh- 

 sum, is a tubular leaf, as in several species 

 of ftllium ; lobelia dortmanna, has a leaf 

 formed of a double tube ; canaliciilatum, 

 expresses a leaf with a longitudinal fur- 

 row ; carrinatwri) one with a prominent 

 line like a keel at its back ; ensiforme, the 

 sword-shaped, or two-edged leaf of the 

 irises ; alcinatum, is used by Dr. Smith, 

 " when the first leaves of a plant give 

 place to others totally different from them, 

 and from the natural habit of the genus, 

 as in many mimosae of New-Holland ;" 

 the first leaves of these are pinnated, the 

 subsequent ones dilatations as it were, of
