 *alx tubular, colored, the limb 4 (4 or 5)-parted, regular, the tube bearmg the siam- 

 ens as many or usually twice as many as its lobes, and free from the ovary, which 

 is 1-celled, 1-ovuled, the suspended seed with little or no albumen. 



Genera 40, specien 875, very Abundant in Australia and S. Africa, sparingly disseminated la 

 Kiiropc and Asia. The only N. American genus is the following. 



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

 interlaced fibers, which are extremely tough, but easily separable. The lace-bark tree (Lagetta) 

 uf Jamaica is particularly remarkable for this property.

 longer than and inserted into the tube ; stylo 1 ; berry 1-seedcd. — Lvs. 

 alternate, simpk. Fls. expanding before the oblong-obovato lvs., 3 

 from each bud. 



D. paliistris L. — A shrub 5f in height when full grown, TJ. S. and Can. The fls. 

 appear in April and May, much earlier than the leaves. They are small, yellow, 

 funnel-shaped, about 3 together, with a bud-like involucre. Lvs. from the same 

 buds, entire, on short petioles, pale underneath. Stam. much longer (ban the 

 calyx, alternately a' long and a short one. Berry oval, small, red. Every part 

 of this shrub is very tough. The twigs furnish "rods for the fool's back," tha 

 bark is used for ropes, baskets, &o. 

 DAPHNE is a genus diSering from Dirca by its spreading calyx limb and 

 included stamens.

 occasionally cultivated. '
