 " Cuauchichic," " chichicuahuitl," " quauhchichic " (Mexico, Hidalgo, etc.); 

 " cuahuchichi " (Morelos); " zapotillo " ; " ovitano " ; " guachichi " (Oaxaca, 

 Reko ; from the Nahuatl cuauchichic, "bitter-tree"). 



The bark is very bitter and is said to contain an active principle, garryine. 

 It is much used in Mexico as a remedy for diarrhoea. 



This species is slightly variable, and several varieties are recognized by 

 Wangerin, but none of them appear to be of systematic importance. One col- 

 lection reported from Chihuahua by Wangerin as G. ovata lindheimeri (Torr.) 

 Coult. & Evans is referable to G. laurif olia. 



2. CORNUS L. Sp. PI. 117. 1753.

 capitate, the heads sometimes involucrate ; calyx limb turbinate or campanu- 

 late, 4-dentate; petals 4, valvate; stamens 4; fruit drupaceous. 

 Flowers in cymes. 



Stone of the fruit compressed ; leaves usually with 5 or 6 pairs of nerves. 



1. C. stolonifera.

Chihuahua. Widely distributed in the United States and Canada. 



Shrub, 1 to 3 meters high, the stems reddish purple, the young branches 

 strigose-sericeous ; leaves ovate or elliptic-ovate, 3 to 10 cm. long, acute, pale

The red-osier dogwood is common along streams in the United States, espe- 

 cially in the West. The branches were often employed by the Indians in mak- 

 ing baskets. This is one of the plants to which the name kinnikinnick has 

 been given, the leaves and inner bark having been smoked, either alone or 

 mixed with tobacco, by the Indians.
