their interstice s. Their many points and edges, presented even to a 
gentle breeze, produce a deep solemn murnmr in the forest; and 
when the storm is abroad and the tempest high, 
" The loud wind through the forest wakes, 
With sound like oi ean'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.' " 
Pinnatifid, may be seen at Fig. 41, cZ; 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. 4], c.) 
Palmate, or 
hand shaped, 
(Fig. 42, aj) 
one species of 
the passion 
flower (Passi- 
Jloia cobTulea) 
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, 6,) differs from the palmate in 
having no space resembhng 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 theii 
margins, they an 
said to be lobed 
and according t 
the number o 
these indenta 
tions, they an 
said to be thret 
lobed, four lobed, 
&c. Fig. 43, a, 
represents a three 
lobed leaf, as may 
be seen in the 
Hepatica triloba.
