Tliis plant almost completely covers the bushes and shrubs over which it runs. 

 Dr. Falmer speaks of a large shrub 15 feet high, with considerable spread of 

 branches, which was entirely hidden by it. I do not flud that this plant is 

 reported froui Mexico, but it seems to be common there, and as it corresponds 

 fairly well with the description and with a single specimen from Brazil, I have 

 no hesitancy in referring it as above. 



Tournefortia hirsutissima (0 L. Sp. PI. ed. 2. i. 201 (1762). Tall shrubby 

 climber covering the tops of the highest trees with its numerous branches: the 

 small drupes at first dull white and Heshy: in age hard and dry, Mauzanillo,

This plant seems to be the same as the one obtained by C. Wright in Nicaragua, 

 and also referred as above. In both of these specimens the leaves are n<5a.rly 

 glabrous in age. In De Candolle's Prodromus this species is described as " fruti- 

 cosa erecta." Also about Colima, January 9 to February 6, 1891. No. 1242. 

 But in these specimens the leaves are very scabrous and more ])ubescent.

Dr. Pabner speaks of this as a tree with a large top, hanging branches, and a 

 great profusion of flowers. The ibnvers generally a]M>ear beibre the leaves, but 

 ■ when both appear together th(^ flowers are found in the axils of the leaves form- 

 ing short, leafy racemes. It is called "Acote" and the bark is used in the prep- 

 ation of a tea which is taken for diseases of the kidneys.
