44914. Acacia spadicigeea Cham, and Schlecht. Mimosacese. 



Bull-horn acacia. 

 "An interesting shrub or small tree, with spreading branches armed 

 with thorns resembling the horns of a bull and consequently called, to- 

 gether with its allies, bull-horn acacia. The thorns attracted the atten- 

 tion of early botanists from the fact that they are usually hollowed out 

 and inhabited by stinging ants which serve as oodyguards, protecting 

 the plant from herbivorous animals. The present species is very closely 

 allied to Acacia comigera of Linnaeus, if not identical with that species. 

 The hollow, indehiscent pods, terminating in sharp spines, inclose a num- 

 ber of hard seeds surrounded by a sugary aril which is much relished by 

 cattle and other animals." (W. E. Safford.)

 (Ipomoea purga Hayne.) Jalap. 



A perennial twining vine which bears handsome rose-purple flowers 

 similar to those of the common morning-glory. It is a native of the 

 eastern slopes of the mountains of western Mexico, at altitudes of 5,000 

 to 8,000 feet, in regions where rain is very frequent and abundant. It 

 is cultivated in Mexico and also in other tropical places for the sake of 

 the drug which is extracted from the dried tubers. In cultivation the 

 plant requires a rich forest loam, and must be supported by trellises.
