T 29. PnmUdiu'ir,/;J loavos, wo sop, are of two «orts : — i . Tho«o with ( lio voius op 

 n(!rv»>HaII nini)in<,' fiojn tlio haso of tlio leaf to tho point (Fi<>-. 85); and 2. Tlioso 

 . where they mostly run fioni tht- midrib to {\\v niar;;in, as in Fi^'. 86. iXet ted -veined 

 leaves likewise are of two sorts, tlio Feaflier-i'rim'il ami the liadlnfi'-n-iiwif, 



130. Fiidlitf - ri'iued (al- 

 so called piinxdebj niin-d) 

 leaves are those in whieh 

 the main veins all s[»rin^ 

 from the two sides of one 

 ril», vi/., tlie midril), like tho 

 jdiime ot" a tt'iither from 

 each side of the shaft. Fig- 

 ures 8:1, 88 97, I JO, 122, 

 \('., represent feather- veined 

 leaves. 



1 ;; I . Uadiide- 1 'i-int'd (al- 

 so called j)(iliii((lrl ij reined) 

 lea'cs aic those which have 

 three or moie main ril)s ris- 

 \\\'^ at once from tht^ jdaee 

 where the feotstalk joins the 

 Made, and commonly diverg- 

 ing, like rays from a centre; tlie veins ])i'anching olf from these. Of this sort 

 are the leaves of the Ma])le (Fig. 84), Mallow, Cnrrant, (irape-Vine, and less 

 distinctly of the Linden (Fig. 83). Such leaves are generally roundish in shape. 

 It is evident that this kind of veining is adapted to round lea\es, and the other 

 .kind for those longer than wide. 



132. Shapes of Leaves. As to general shape, the following are the nan)es of the 

 princijial sorts. (Jt will be a good exercise for students to look up examples 

 which iit the delinitions.) 



Li?i''ar : narrow, several times longer than wide, and of about the same 

 width througbo it, as in Fig. 87. 



Lanee-ti/ta^Kd or Lanceolate ; narrow, much longer than wide, and tapering 

 .upwards, or both upwards and downwards, as in Fig. 88. 



OUoiKj ; two or three times longer than broad, as in Fig. 89. - ' '
