 Tree. — Lvs. oblong, obovate, very entire, acute at each end, the petiole, 



midvein and margin villous ; fertile ped. 3 — 6-flowered ; nut short, obovate, 

 obtuse, striate. — This tree is di.sseminated throughout the U. S. : it is found 

 30 — 70f! high, the trunk 1 — 31'! in diameter, with horizontal branches forming 

 a pyramidal summit. The bark is light gray, similar to that of the white oak, 

 and, like the next species, broken into hexagons. Leaves tough and firm, 2— 

 5' long, and h as wide, often with 1 or more blunt teeth. Flowers small, green- 

 ish, in small clusters on a long, branching peduncle, the fertile ones succeeded 

 by a few deep blue, oblong drupes. The M'ood is white, fine-grained, rather 

 soft, the texture consisting of interwoven bundles of fibres, rendering it very 

 difficult to split. It is thereibre useful for beetles, naves of wheels, hatters' 

 blocks, &c. Jn.

 sections of the Northern and Middle States. The trunk when full grown is 

 30 — 50f high and 15 — 20' in diameter, the bark divided by deep furrows into 

 hexagons. Leaves alternate, smooth, 2 — 4' in length. Flowers small and 

 obscure, the fertile ones producing a ifruit of a deep blue color, growing in

Order CXIV. THYMELACE..^.— Daphnads. 



Shrubs with a very tenacious bark, alternate or opposite, entire leaves and perfect flowers. 



Cal. free, tubular, colored, limb 4 (rarely 5)-cleft, iinbricatL-d m aestivation. [as many. 



Sla. definite, inserted into the calyx and opposite to its lobes when equal to them in number ; often twice 



Ova. sohtary, with 1 ovule. Style 1. Stigma undivided. 



Ft. hard, dry, drupaceous. Albnmen or thin. 



Genera 38, species 3oo, very abundant in Australasia and S. Africa, sparingly disseminated in Europe 

 and Asia. The only North American genus is that which follows. 



Properties. — The bark is acrid and caustic, raising blisters upon the skin. It is composed of interlaced 

 fibres which are extremely tough, but easily separable. The lace-bark tree CLagetta) of Jfmiaica is par- 

 ticularly remarkable for this property.
