OF LEAVES. 
their interstices. Their many points and edges, presented even to a 
gentle breeze, produce a deep solemn murmur in the forest 3 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 v/rapt up in a kind of enthusiasm to Him, 
who 'walks on the wings of the wind.' " 
Pinnatijid, may be seen at Fig. 41, d ; leaves of this form are 
sometimes tinely divided, lilse 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, aj) 
one species of 
the passion 
flower (Passi- 
fo'ia ccBTulea) 
affords a good 
example of this 
kind of leaf 
The oblong 
segments^ hke 
fingers, arise 
from a space 
near the peti- 
ole, which may 
be considered 
as resembhng the palm of the hand. 
Digitate, or fingered leaf (Fig. 42, 6,) 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 
Hor.- e Chestnut, 
Connate, (Fig. 42, c ;) the bases of opposite leaves are united so as 
to appear one entire leaf 
Fig. 43. 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, 
&c. Fig. 43, «j 
represents a three 
lobed leaf, as may 
be seen in the 
Repatica triloba.
