184 ECONOMIC BOTANY OF ALABAMA 



Benzoin melissaefolium (Walt.) Nees. 



A perfectly distinct species, but rare and little known. Said 

 by Dr. IMohr to have been collected by Buckley near Allenton, 

 Wilcox County ; l)ut apparently not seen in Alabama by any botan- 

 ist in the last To years. 



SAXIFRAGACEAE. Saxifrage Family. 



In the broader sense this includes about 75 genera and 1000 

 species, mostly herbs and shrubs, in the cooler parts of the world. 

 Several are ornamental. 



PHILADELPHUS, Linnaeus. Svringa or Mock Oraxge. 



Medium-sized deciduous shrubs, with handsome white flow- 

 ers, blooming mostly in May. The limits of the species are rather 

 uncertain, and at least five species have been credited to Alabama, 

 but most of them look very much alike, especially when not in 

 bloom. Except for first species listed below, I have not been able 

 to distinguish them in my field work, and all the others will be 

 lumped together for the present. 



They are often cultivated for ornament, and some of the cul- 

 tivated forms do not seem to be exactly matched by any known in 

 the wild state. 



Philadelphus hirsutus, Nutt. 



Grows on dry siliceous cliffs, mostly among the mountains. 



lA. Along Cypress Creek near Florence (Mohr). 



2A. Jackson County (Harbison); UeKalb County (Mohr).
