their interstices. Their many points and edges, presented even to a 

 gentle breeze, produce a deep solemn mm-mur in the forest; and 

 \vhen the storm is abroad and the tempest high, 



" The loud wind through the fotest wakes, 

 With sound like ocean s roaring, wild and deep. 

 And in yon gloomy pines strange music makes." — 



Burns, in describing such a scene, says ; " this is my best season for 

 devotion : my mind is wrapt up in a kind of enthusiasm to Him, 

 who 'walks on the wings of the wind.' " 



Piimatifid, may be seen at Fig. 41, d ; leaves of this form are 

 sometimes jfinely divided, like the teeth of a comb ; they are then 

 said to be pectinate. 



Lyrate, differs from pinnatifid in having its terminating segment 

 broader and more circular. (See Fig. 41, c.) 



Palmate, of 

 hand shaped, 

 (Fig. 42, a;) 

 one species of 

 the passion 

 flower (Passi- 

 flora coerulea) 

 affords a good 

 example ofthis 

 kind of leaf 

 The oblong 

 segments, like 

 fingers, arise 

 from a space 

 near the peti- 

 ole, which may 

 be considered 

 as resembling the palm of the hand. 



Digitate, or fingered leaf (Fig. 42, &,) differs from the palmate in 

 having no space resembUng the palm of a hand; but several distinct 

 leafets arise immediately from the petiole, as may be seen in the 

 Horse Chestnut. 



Connate, (Fig. 42, c ;) the bases of opposite leaves are united so as 

 to appear one entire leaf 



Lobed, when 

 leaves are deeply 

 indented at their 

 margins, they are 

 said to DC lobed j 

 and according to 

 the number ol 

 these indenta- 

 tions, they are 

 said to be three 

 lobed, four lobed^ 

 &c. Fig. 43, a, 

 represents a three 

 lobed leaf, as may 

 be seen in the 

 Hepatica triloba.
