TWO NEW SPECIES OF SELAGINELLA IN THE 

 SOUTHERN FLORA 



By Lucien M. Underwood 



Although the number of species in the Selaginclla rnpcstris 



group has increased from three to sixteen within the limits of the 



United States through the work of the writer and that of Dr. Georg 



Hieronymus, of Berlin, the mine does not appear to be exhausted 



yet. The two following species are representatives of the flora 



of North Carolina, the first from the sandy barrens of the coastal 



plain and the second from the highlands at the opposite side of 



the state. 



Selaginella acanthonota sp. nov. 



Stem and branches stout, ascending, sending out abundant root- 

 lets from the upper portions, softly hairy at the tips. Leaves in 

 8-10 regular series, 2 mm. long, gradually tapering into a rough- 

 ened soft white awn one half to one third their length, with about 

 1 2 short irregular cilia on either side of the dorsal groove ; strobiles 

 fully 10 mm. long, quadrangular, the sporophylls broadly triangu- 

 lar and ciliate like the stem leaves. 



Growing in sand along the coast and near it, North Carolina. 

 A small fragmental specimen of this species was collected many 

 years ago by Mr. Curtis and is in the Torrey herbarium ; more 

 abundant material was collected during the summer of 1899 in 

 pine barrens near Wilmington, by Professor C. L. Williamson and 

 has been grown in the conservatories of the New York Botanical 

 Garden. The plant is a close ally of 5. rupestris but differs not- 

 ably in the regularly many- ranked leaves, in the dorsal cilia, from 

 which the species receives its name, and in other characters. 



Selaginella Sherwoodii sp. nov. 



Plants forming densely branched compact tree-like tufts 6-8 

 cm. high. Stems repeatedly branching, erect or ascending, root-
