A shrub or tree. Flowers (in Pennsylvania, New- 

 Jersey, &c.) in April and May. — Ripens its fruit in Au- 

 gust and September. 



The leaves are deciduous, and before falling (in Penn- 

 sylvania, in the months of September and October) as- 

 sume a fine red or crimson hue, which adds much to 

 the beauty of a North- American forest. (See my Ele- 

 ments of Botany. Part 1. p. 64, 65.) Several other 

 species of Cornus (even C. canadensis, if I do not mis- 

 take) are clothed, about the same season of the year, in 

 a similar livery. 



The beautiful involucre of this species of Cornus is 

 well worthy the attention of the physiological botanist. 

 " Each foliole is composed of two distinct parts, each 

 part being entirely the production of a separate season ; 

 and, contrary to the common order of vegetation, the 

 upper part is produced first : that is, the points of the 

 folioles grow in one season, forming a hybernacle, and 

 the following year the lower parts of the folioles grow 

 and burst it open. The points now become callous, 

 and wrinkle the leaf, and this gives them the appearance 

 of being end bitten." Mr. David Thomas, MS.
