Some new or otherwise noteworthy plants from the coastal plain of 



Georgia 



Roland M. Harper 



In five seasons of botanical exploration in the coastal plain of 

 Georgia I have accumulated a few plants of special interest which 

 were not sufficiently studied in time to be mentioned in the sep- 

 arate reports for each season which have already been published.* 

 All but two of those mentioned below are to be included in a flora 

 of the Altamaha Grit region which is now in press, and it seems 

 desirable to discuss them here in advance, so that they will not 

 require a disproportionate amount of space in the flora. 



Lycopodium pinnatum (Chapm.) Lloyd & Underw. Bull. Torrey 



Club 27: 155. 1900 



The name of this pine-barren plant is antedated by Z. pinnatum 

 Lam. (Encyc. 3 : 654. 1789), said by its author to grow on trees 

 in the West Indies. This species was mentioned by Beauvois 

 (Prodr. Aetheog. 1 10) in 1805, Swartz (Syn. Fil. 186) in 1806, and 

 Poiret (Encyc. Suppl. 3: 541) in 1813, but seems to have been 

 overlooked or ignored by later authors. There is no possibility of 

 its being identical with our plant of the pine-barrens, so the latter 

 should be re-named ; I therefore propose to call it Lycopodium 

 prostratum, in allusion to one of the characters by which it differs 



conspicuously from its nearest relative, L. alopecuroidcs. 



Sporobolus teretifolius sp. nov. 



Culms tufted, wiry, 7-8 dm. tall, erect or nearly so : leaves 

 wiry, flexuous, ascending or recurved, about half as long as the 

 culms, less than 1 mm. wide, oval in cross-section, compressed 

 laterally, grooved on the ventral side : f panicles about half the

■ f The following notes on the internal structure of this peculiar leaf may be Of 

 interest. The dorsal surface completely surrounds the leaf, and is remarkably smooth f 

 without perceptible furrows or trichomes. The ventral surface is confined to the very
