substituted to the C- florida. Three of the best 

 known as most efficient will be mentioned here. 



1. Cornns Sericea or Blueberry Cornel, vulgarly 

 called Sivamp Dogwood or Rose Willow, is a shrub 

 from six to twelve feet high, growing from Canada 

 to Virsjinia, near swamps and streams. There is a 

 figure of it in W. liarton, fis;. 9. The leaves are like 



those of C. Jlorida^ and silky beneath, but the flowers 

 are very different, in large terminal cymes, without 

 involucrum, yellowish white, and succeeded by large 

 clusters of small round blue berries. — The bai'k is less 

 bitter, more astringent and pleasant to the taste than 

 in C. Jlorida. 



2, C. circiniiata or Round leaved Cornel, also 

 called Alder Dogwood, is a shrub with v,^arty twigs, 

 large rounded leaves, w^oolly beneath: the fiov;ers 

 are in cymes, without involucrum. It grows from 

 Canada to Pennsylvania, — Prof. E Ives of New^ Ha- 

 ven, and Dr. A. Ives of New York, extol this kind, 

 they say it resembles the pale Peruvian Bark, Cin- 

 chona lancifolia : an ounce of the bark yields by boil- 

 in"' 150 grains, of an astringent and intensely bitter 

 extract. In use it is found preferable to Colombo and 

 Cinchona cordifoliay it is much employed in the 

 Northern States, in substance and otherwise, for 

 diarrhcBa, dyspepsia; but is too heating in fevers. 



3. C- alba or Wax-berry Cornel, is also a shrub, 

 •rrowins: from New Endand to Siberia in Asia, with 

 broad ovate leaves, white beneath, flowers in cymes, 

 berries round, white like wax. — All these blossom 



1 



from May to June: many birds are fond of their ber- 

 ries and the beavers eat their bark.
