seems to be rare and local in Alabama. Helianthus longifolius 

 Pursh 136 was collected in dry sunny situations along rocky slopes 

 and on the bluff above the gorge. In the summer of 1899 I col- 

 lected this rare helianthus near Albertville, Alabama. Parnassia 

 asarifolia Vent., 137 not common in Alabama, grows in several spots 

 along small streams near Pisgah. Viola hastata Michx., 138 rare in 

 Alabama, is found in shady situations, though never plentifully. 

 Trillium stylosum Nutt. 139 is abundant in the region, and is the only 

 species of trillium observed on the table-land about Pisgah. 

 In the sand along Bryant's creek, I observed Polygonella a?nericana 

 (Fish. & Meyer) Small 140 and with it Eriocaulon decangulare L. 141 

 In all the small swamps and moist swales in the woods Sarracenia 

 catesbcei Ell. 142 is found, and a plant common to the swamps is 

 Helianthus polyphyllus Small. 143 



Cralcegus uniflora Muench. 144 is a common undershrub in the 

 rocky woods and Cralcegus rubella Beadle 145 is also quite common. 



The benches and slopes along the western escarpment of the 

 mountain offer a promising field for the collector. Here in many 

 places the primeval forest remains undisturbed. Here Castanca 

 dentata (Marsh.) Borkh. 146 reaches its best development in the 

 state of Alabama. On the table-land the chestnut is almost extinct, 

 owing in a great measure to the custom of burning the woods to 

 improve the pasturage. On this part of the mountain Polymnia 

 Icevigata Beadle 147 is frequent. I have traced this species for a 

 distance of seventy-five miles along the mountain, and found it 

 always on the sandstone above the limestone formation. At 

 the base of the mountain, on the limestone formation, I found 

 Neviusa alabamensis A. Gray. 148 This station is more than one 

 hundred miles from Tuscaloosa, Alabama, the only other station 

 known for this rare shrub. Associated with neviusa are Staphylea 

 trifolia L., 149 Tilia heterophylla Vent., 150 Aristolochia tomentosa
