where there is enough of it it supports copses of shruljs and trees. 

 At the upper edge of a sloping rock outcrop, and at various other 

 places where the surface is irregular, there may be a gentle seepage 

 of water, giving rise to bog conditions. 



In the following plant list all these minor habitats are com- 

 bined, but only such trees and shrubs are included as occur in 

 ^'island" copses, and not those in the bordering forests.. My notes 

 are not complete enough yet to warrant going into finer details, 

 as Miss Whitehouse did in her Texas granite study already cited 

 and Costing and Anderson in their paper on east-central North 

 Carolina. But as usual I have separated trees, shrubs, herbs, etc., 

 and then arranged the species in approximate order of abundance 

 in each group. Evergreens are indicated by heavy type. Weeds, 

 presumably brought in by cattle, sightseers, picnickers, etc., are 

 omitted for the present, though of course it is not always possible 

 to draw a sharp line between weeds and natives. Among the 

 common weeds of such places, some of which may possibly be 

 indigenous, are Sarothra gentianoides, Diodia teres, Senecio Smallii, 

 and Ambrosia elatior. 



This list is made up from observations in Randolph County 

 only. The Chilton County locality previously mentioned (visited 

 in June, 1936, May, 1937, and August, 1938) is omitted to avoid 

 complications, because it is somewhat different in character, but 

 some of its interesting plants may as well be noted in passing. 

 ClieilantJies tomentosa occurs there under ledges, Arenaria patula, 

 Dclphinhini carol inianum and Taliniun parviflorum on gentler 

 slopes, and Rhapidophyllmn at the base of a cliff.^ Some of these 

 plants are often found on limestone, and it may be that the gneiss 

 at that point is more calcareous than usual. 



Visits to the rocks in Randolph County and elsewhere in spring 

 and fall would doubtless reveal additional species, that are not 

 readily recognizable in summer, and make more certain the iden- 

 tification of some that I could only guess at when flowers were 

 not available, and thus eliminate some of the interrogation points 

 in the list. But such an opportunity cannot be counted on in the 



^ See Castanea, 3: 24. (March) 1938. Since the above was written W. Wolf 

 has described the Chilton County Talinmn as a new species, T. appalaclii- 

 anum, in the American Midland Naturalist for September, 1939. All or 

 nearly all the known stations for T. parviflorum are west of the Mississippi 

 river.
