their interstices. Their many points and edges, presented even to a 
gentle breeze, produce a deep solemn murmur in the forest; and 
when the storm is abroad and the tempest high, 
“ The loud wind through the forest 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. 5 ” 
Pinnatifid , may be seen at Fig. 41, d; leaves of this form are 
sometimes finely 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 , or 
hand shaped* 
(Fig. 42, a;) 
one species of 
the passion 
flower ( Passi - 
flora coerulea} 
affords a good 
example of this 
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 resembling 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 be lobed, 
and according to 
the number of 
these indenta¬ 
tions, they are 
said to be three 
lobed , four lobed% 
&e. Fig. 43, a , 
represents a three 
lobed leaf, as may 
be seen in the 
Hepatica triloba .
