LEAVES. 23 



of forms of leaves and terms for these which botanists 

 enumerate, presenting to the beginner a wilderness of 

 words, enough to deter him from journeying farther. 

 Dr. Drummond has not, as it appears to me, been 

 happy in his endeavour to simplify this matter, by ar- 

 raying leaves as named from "parts of the animal 

 body;" from "instruments of war;" from " musical 

 instruments;" from "mechanical bodies;" and from

 to the objectionable term vein, divides leaves into vein-

 ribbed, false /y-ribbed, radiating, feather- veined, and 

 hidden veined ; most of the corresponding Latin terms 

 which he has invented are quite barbarous: his falsely 

 I do not pretend to understand. 



I shall follow the expansion of the ribs, according 

 as they are throughout regular, or as one or more pairs 

 of the side branches are more or less long than the 

 others ; and again, as these branches are united in a 

 single leaf-plate, termed simple leaves, or divided into 

 several small leaf-plates on the same common leaf- 

 stalk, termed compound leaves. 



Simple Leaves. 



When the mid-rib and its branches form a simple 

 leaf*, it may be line-like J , as in juniper ; awl-shaped 2 , 

 as in the jonquil ; spear-shaped 3 , as in rib- wort; sword-
