Harper : Some Alabama plants 535 



the average size, some being about 25 feet tall, with trunks 6 inches 



in diameter. 



Osmanthus americanus (L.) B. & H. 



In Alabama as well as in Georgia this evergreen shrub or 

 small tree is by no means confined to the immediate vicinity of 

 the coast, as was thought to be the case up to a few years ago.* 

 It occurs at a number of places in the Eocene region, and extends 

 inland to Chilton, Autauga and Elmore Counties, growing along 

 streams in the metamorphic portion of the first-named, like Illicium 

 fioridannm. (It has also been found in Lee County. )f Like 

 Illicium again, it has a number of Asiatic relatives, and may have 

 had a similar history. 



Trachelospermum difforme (Walt.) Gray 



Still another coastal plain plant found occasionally in the upper 

 districts. Dr. Mohr has already reported it from Morgan and 

 Walker counties, and on May 13 I found it at two or three places 

 along the Calvert Prong of the Locust Fork of the Warrior River 

 in Blount County, on upper Carboniferous strata (Coal Measures). 

 This too has Asiatic relatives, like the preceding. 



In Georgia I have found this species almost always along 

 streams which have passed through calcareous regions,^ and this 

 new Alabama station for it is no exception to the rule. For al- 

 though the Calvert Prong runs lengthwise of Sand Mountain, 

 occupying the synclinal trough of the plateau, like several other 

 streams,§ it has some tributaries entering above the point in ques- 

 tion which rise in the limestone valley on the southeast and flow 

 into the mountain. || This peculiar type of drainage I have not 

 met with anywhere else than in Blount County.

f What is perhaps the first specimen of this species collected in the Metamorphic 

 region was distributed by Professor and Mrs. Earle (no. j6) 9 and is labeled "Occa- 

 sional, usually along streams, often on rocky banks. Auburn, Lee Co., April II, 



1900."

 This is very well shown by the map of Blount County in the report of the field 

 operations of the U. S. Bureau of Soils for 1905, taken in connection with the topo- 

 graphic maps of the same region, published by the U. S. Geological Survey.
