1924] PALMER, THE LIGNEOUS FLORA OF RICH MOUNTAIN 1» 



mm. thick, 5-celled and deeply 5-lobed, with sharp ridges and sutures, 

 rarely 4-celled or less; inflorescence scattered at the ends of the branches; 



flowers not seen. 



A shrub often less than 5 decimeters in height on dry rocky slopes, 

 but in the protection of rocky ledges T >ecoming nearly or quite 2 meters 

 tall, with thin, freely exfoliating brownish-gray bark. This species appears 

 to be most closely related to Hypericum lobocarpum Gattinger, of central 

 Tennessee, but differs from it markedly in its firmer, narrower leaves, 

 with more conspicuous fascicles of smaller ones in their axils, in its more 

 scattered inflorescence and in the more slender sharply lobed capsules. 

 The habitat also is quite different, Hypericum lobocarpum growing in dense 

 swamps, according to the description. In appearance our plant more 

 closely resembles Hypericum densiflorum Pursh.
