CEANOTHUS. New Jersey Tea. 

 (Family Rhamnaceae). 



For our purposes low and de- 

 ciduous shrubs, sometimes with 

 twig-spines. Twigs rounded, 

 rather slender, more or less pu- 

 berulent, green or brownish: pith 

 relatively large, white, continuous, 

 rounded. Buds small, solitary, 

 sessile or often developing the first 

 season, ovoid, with several glab- 

 rate stipular scales of which the 

 lowest only are distinct and the 

 leaf-blades are very hairy. Leaf- 

 scars alternate, half-round, some- 

 what raised, small: bundle-trace 1, 

 transverse, more or less evidently 

 compound; sometimes distinctly 3: 

 stipules small, persistent or leav- 

 ing narrow scars. Bases of the 

 half-inferior clustered capsules 

 usually persist and some tender 

 species have opposite evergreen 

 leaves. In California known as wild lilac.

Except for the short time when they are in flower, the 

 New Jersey tea shrubs of the Northeast are of little interest; 

 but several Mexican and Californian species have been favor- 

 ites in the milder climate of Europe for many years, and a 

 number of their hybrids are very attractive in English gar- 

 dens.
