A. BALSAMEA AND FRASERI 73 
A pectinate arrangement, by which is meant 
leaves on the lateral branches shaped after the teeth 
of a comb, should give one the idea of a flat and 
horizontal arrangement of leaves. Often if you turn 
the branchlet over, it answers the description truly 
enough as far as the lower side is concerned, but on 
the top side they vary, and do not convey the idea 
of regularity that you are accustomed to see in the 
teeth of the dressing-table article. V-shaped is when 
the upper leaves assume the form and lines of the 
alphabetical letter. A succession of them arrayed 
close together, if you look down their line, gives the 
appearance as if a plough-share had drilled a furrow 
down their middle. At the bottom of the furrow 
the stem is visible, and this parting, as on the human 
head of hair, is sometimes narrow, sometimes wider, 
according to circumstance or the age of the owner. 
When upon this vacant furrow another crop of leaves 
grows from the stem, these are called median leaves, 
and very properly, as they grow in the middle. Trees 
thus equipped are described in Group III. 
A. Batsamea and A. Fraseri.—This Group II 
consists of some ten species, all of which, with the 
exception of Balsamea and Fraseri, are quite likely to 
be met with in Pinetums. These two, then, can be 
dismissed with a few words. We can almost com- 
mence with them, and end with them, by a poetical 
reference from Longfellow : 
Give me of your balsam, O fir tree, 
Of your balsam and your resin. 
Seemingly it contained some very useful essential in 
the construction of Hiawatha’s canoe, and from the 
description we may conclude that the value of this 
resinous fir was held in high estimation by the natives 
who lived in its vicinity and freely appropriated its 
uses, which included medicinal extracts and oil of fir
