38 MORPHOLOGY 



branch repeatedly into smaller and smaller veins; 

 which latter, anastamosing or uniting with one 

 another, form a network, as in Peepul, Mango, 

 Banyan, &c. Such leaves are described as reticu- 

 late or net-veined. In Monocotyledons, on the 

 other hand, the minor veins do not, as a rule, form 

 a network, hence such leaves are described as non- 

 reticulate. In kala-jam {Eugenia Jambolana),

golap-jam or Rose-apple, and similar other plants, 

 there is a sub-marginal vein in each half of the blade 



(fig. 36). 



The margin of a leaf may be entire or slightly 

 indented, and the nature of such margins has been 

 described. If, however, the margin is deeply in- 

 dented, each segment of the blade is termed a lobe, 

 and the whole leaf is said to be lobed. Lobed 

 leaves of the pinni-veined type are termed pinnifid, 

 PiNNiPARTiTE, and pinnisect (fig. 37), according to 

 the depth of the indentations. Lobed leaves of the 

 palmi- veined type are similarly termed palmifid,
