Funnel-shaped, as in the

Horn-like, 783. 



Trumpet- shaped, 784. 



Square, 785. 



Hound, round and fi- 

 brous, 786, or round and 

 laminated, &c. 



Globular, like the rose, 

 787, or dahlia, &c. 



Semi- globular, like the 

 788, or the Mistfe. 



Triangular, like the 

 pAtre- coirrf, 789. —These, 

 and other figures of re- 

 semblance, being borne 

 in mind, teach us how 

 to notice and appreciate 

 the beauties of flowers. 



In some instances, the 

 petals of flowers are veined, 

 or netted, as in the hen- 

 bane, 790. 



In addition to the pecu- 

 liarities of leaves, already 

 pointed out, 1 93, there are 

 others well worthy of ob- 

 servation : — Some have 

 their surfaces deeply cor- 

 rugated, the depressions 

 causing variations of 

 colour, 791. 



The venation of others 

 presents the appearance 

 of a series of regularly 

 disposed plates, or laminae, 

 with a smooth border, 792.

In others the venation 

 consists of a series of 

 parallel lines, intersected 

 by a midrib, 793. 



Some leaves which are 

 divided into two or more 

 semi-circular parts, are 

 called bilobed, 794, or 

 trilobed, &c. 



The reni/orm leaf, 795, 

 is so called, from its re- 

 semblance to a kidney. 



Leaves shaped like a 

 half moon are lunate, 796. 



Small scales at the foot 

 of the petioles, are stipules, 

 797. 



In some leaves the cor- 

 rugations are in character 

 with the form of the leaf, 

 which appears to be em- 

 bossed thereby, 791. In 

 others, they are homo- 

 geneal, or similar through- 

 out the leaf, 798. 



In the fern tribes the 

 leaves are frequently 

 notched, so as to divide the 

 leaf into one or more 

 segments, 799. 



Sometimes leaves are 

 spotted, the light spots 

 being angular and well 

 defined, 800. In the holly 

 tribes the leaves are 

 variegated, some having 

 irregular yellow spots, 

 others being entirely 

 yellow. 



In others, the spots are 

 $ubdued and blotched, 801. 



While, in other in- 

 stances, they are square, 

 and regularly chequered, 

 802.
