30 PRINCIPLES OF BOTANY, ETC: 
36. Awl-shaped, (subulatum), a linear leaf, which 
is sharply pointed. 
37. Needle-shaped, (acerosum), a linear leaf that 
iS rigid, and generally endures through the winter; 
as in the pine-tribe, Pinus. , 
38. Triangular, (triangulare), when the circum- 
ference represents a triangle, the apex of which 
makes the point of the leaf, as in the birch, Betula 
alba. 
39. Quadrangular, quinquangular, (quadrangu- 
lare, quinquangulare), when the circumference of 
the leaf has 4 or 5 angles, as in the Menispermum 
canadenses : aa 
40. Intire, (integrum s. indivisum); which is not 
at all cleft or divided, fig. 203. 
41. Lobed, (lebatum), when a leaf is deeply di- 
vided nearly half its length into lobes. According 
to the number of lobes it is denominated bi-lobed 
(i-lobum), as in Bauhinia; tri- lobed, (tri-lobum), 
carne: (quinguelobum), as In the hop, Hu- 
mulus Lupulus, &c. fig. 32. 
42; Palmated, (palmatum), when there are five 
or seven very long lobes, that 1s, when the segments 
are more than half way divided. | | 
4.3. Divided, ( partitum), when in a roundish leaf 
the division extends to the base. 
44, Torn, (Jaciniatum), when an oblong leaf has 
several irregular clefts. 3 
45. Smuated, (sinuatum), when on the sides of 
an oblong leaf there are round imcisures, as in the 
oak, Quercus robur, fig. 289.
