 Collected near Gregory, San Patricio county, altitude 35 feet, where 

 it is plentiful as a tall shrub or small tree. The leaves of these speci- 

 mens are much smaller than are those from Florida, and the flower clus- 

 ters much shorter. The bark is whitened, and in that particular at least, 

 agrees with Buckley's Z. hirsutum, the type of which was collected in the 

 same region, near Corpus Christi, but he does not state on which side of 

 the Bay.
