191 LINN/EAN NATURAL SYSTEM. 



mon receptacle, drawn out like a thread, on which the 

 flowers stand in alternate order. Salix or willow, popn- 

 lus or poplar, quercus or oak, &c. 



They are all either trees or shrubs, with alternate leaves and 

 monoecious or dioecious flowers. Many of them produce but one 

 seed from each flower. The styles are usually two or three. The 

 flowers come before the leaves. 



ORDER LI. CONIFER .. 



52. The plants of this order, are denominated coni- 

 ferae, because they bear a strobile or cone, a species of 

 seed-vessel formed by a catkin with hardened scales, 

 each scale containing a seed at its base. Pinus or fir- 

 tree, cupressus or cypress, juniperus or juniper, &c. 



All the conifene properly bear cones, though in some instances, 

 {as in juniper, &c.) their fruit seems of a very different nature. 



ORDER LII. COADl'NAT^E. 



53- The coadimatae from coadunare, to join, are so 

 termed from the general appearance of the seed-vessels, 

 which are numerous, and being slightly joined below, 

 form altogether a single fruit in the shape of a sphere or 

 cone ; the parts of which however are easily separated. 

 Such are magnolia, tulip-tree, &c. 



ORDER LIII. SCABRIDE.'E. 



54. Scabrideae, derived from scaber rough, consists of 

 plants with rough leaves, which seem to be a kin to the 

 asperifolits ; only their degree of roughness is much 

 greater. Hemp, fig, &c.
