528 Harper : Some Alabama plants 



lapoosa River near Tallassee (the same locality mentioned above 

 in connection with Taxodinm distidmni). Many of the specimens 

 observed there and in the neighboring Cretaceous region are dead, 

 however, and it is probable that those now living came from seeds 



which managed to survive the freeze. 



The occurrence of this species there at all was somewhat of a 

 surprise, for it is almost confined to the coastal plain, barely enter- 

 ing the Metamorphic region for a couple of miles at its extreme 

 southern edge in Georgia and Alabama, about latitude 32 30'. 

 Just why the inland edge of the range of an epiphyte should so 

 nearly coincide with a geological boundary is an unsolved prob- 

 lem. It is significant in this connection that it shows a decided 

 preference for trees growing in calcareous soil (as wa:s noted by 

 Dr. Hilgard in Mississippi in i860 and by Dr. Smith in Alabama 

 in 1894) ; but the reason for this is equally obscure. 



UVULARIA FLORIDANA Chapm.

southwest of Montgomery, April 23, 1906. This species is not 

 mentioned by Dr. Mohr, but there is a specimen in the Torrey 

 Herbarium collected by Buckley in May, 1841, in Alabama, 

 locality not specified, but presumably in Wilcox County, like most 

 of Buckley's other Alabama plants.* 



Myrica carolinensis Mill.

In habitat and distribution this is very similar to Anchistea vir- 

 ginica, already mentioned. f In Alabama I have noted it in eight 

 coastal plain counties, also in sandy bogs in Marshall (on Sand 

 Mountain), Cherokee (Coosa valley), Clay, Chilton and Tuscaloosa 

 counties, in the older parts of the state. The specimens at these 

 places, however, are very small, being scarcely more than knee- 

 high. 



The explanation suggested for the occurrence of Anchistea out- 

 side of the coastal plain will not apply so well to this case, for the 

 Marshall and Clay County stations at least have in all probability
