KINDS AND FORMS OF LEAVES.

151. Leaves without Distinction of Footstalk and Blade, or with no very obvious 
distinction of parts. Of this kind, among several others, may be mentioned, — 
Needle - shaped 
leaves, such as 
those of Pine-trees 
and Larches (Fig. 
134). These are 
long, slender, and 
rigid, and often with 
little if any distinc- 
tion of sides. 
Awl-shaped or 
Subulate leaves are 
those which from a 
broadish base ta- 
per into a sharp 
and rigid point, like 
Ternately decompound, or four times compound leaf. 
one sort of those of the Red Cedar and Arbor Vitae (Fig. 135, 
those on the larger branchlets). Those on other branclilets, as 
at a , are shorter, blunt, and scale-shaped . 
Thread-shaped or Filiform 
leaves ; round and stalk-like, as 
those of the Onion. 
Equitant leaves, like those of 
Iris (Fig. 64), which are folded 
together lengthwise, as may be 
seen at the base, where they 
override each other. They grow 
upright, with their faces looking 
horizontally, instead of having an upper and a lower surface, as most leaves do.
