420 CONIFERS. (FINE FAMILY.) 



Subclass JI. GYMNOSPfeRlVLE. 



Pistil represented by an open scale or leaf, or entirely wanting;

 tilized by the direct application of the pollen. Cotyledons often 

 more than two. 



ORDER 111. COJVIFERJE. (PINE FAMILY.) 



Trees or shrubs, unth resinous juice, mostly with awl-shaped or needle- 

 shaped entire leaves, and monoecious or dioecious flowers in catkins, destitute

 a homogeneous large woody fibre which is marked with circular disks on 

 two sides.) An important and rather large Order; comprising the three 

 following Suborders : 



SUBORDER I. ABIETINE^E. THE PROPER PINE FAMILY. 



Fertile flowers in catkins, consisting of open imbricated carpels in the

 Ovules 2, adherent to the base of each carpellary scale, their orifice turner 

 downward. Buds scaly. 



1. PINUS. Leaves 2-5 in a cluster from the axil of a scale-like primary leaf, persistent. 



2. ABIES. Leaves all scattered on the branches and alike, persistent 



8. LAHIX. Leaves many in a cluster, the primary ones similar, deciduous. 



SUBORDER II. CUPRESSINE^E. THE CYPRESS FAMILY.

* Flowers monoecious. Strobile dry, opening at maturity.
