Panicum strigosum Muhl. ; Ell. Sk. 1 : 126. The type is well matched by No.

 Panicum ciliatum Ell, Sk. 1 : 126. 



Panicum ensifolium Baldw. ; Ell. Sk. 1 : 136. (Fig. 4.) This is exactly the form 

 described by Ashe as Panicum cuthbertii, Journ. E. Mitch. Sci. Soc. 15:48. 

 1898. The grass described by Ashe, 

 Journ. E. Mitch. Sci. Soc. 1. c, 46. 

 as Panicum ensifoliinn Baldw., is 

 Panicttm tenue Muhl. 



Panicum barbulatum Michx. ; Ell. Sk. 

 1:127. This is very distinct from 

 the form considered as Panicimi 

 havhnlatiim Michx. to-day, and is 

 proposed below as a new species. 



PANICUM SUBBARBULATUM 

 Scribn. & Merrill sp. nov. {Panicum 

 barbulatum of Ell. Sk. Bot. S. C. and 

 G-a. 1 : 127. 1817, not Michx. Fl. Bor. 

 Am. 1:49. 1803. 



An erect or ascending, glabrous, caespi- 

 tose perennial 4-9 dm. high, with 

 small panicles, bearded nodes, and 

 pubescent spikelets. Culms wiry, 

 simple, or becoming branched above ; 

 nodes bearded with rejflexed hairs; 

 sheaths much shorter than the inter- 

 nodes, ciliate on the margins ; ligule 

 a short ciliate ring; leaf-blades lan- 

 ceolate, primary ones 5-6 cm. long, 

 5-8 mm. wide, spreading, the second- 

 ary ones 3-4 cm. long, 3-5 mm. wide, 

 narrowed at the base, acute, scabrous 

 on the margins, the nerves rather 

 prominent. Panicles exserted, ovate, 

 4-7 cm. long, the branches ascending, 

 Spikelets ovate, obtuse, 2 mm. long, 

 pubescent; first glume about one- 

 fourth as long as the spikelet. 



The type of the species in the herbarium 

 of Elliott is w^ell matched by the fol- 

 lowing specimens: 3600a A. H. Cur- 

 tiss, Sumpter County, Pla., margins 

 of pine-barren ponds; 3388 S, M. Tracy, June 13, 1897. Morrisonville, Miss. 



This species is readily distinguished from Panicum barbulatum Michx., by its 

 smaller size, smaller leaves, and panicles and larger pubescent spikelets.

Panicum melicarium Michx. ; Ell. Sk. 1 : 128. Not in the herbarium. There is, 

 however, a specimen of Sporoboln^ juncens in the collection, evidently from 

 Muidenberg, so labeled, but corrected to Agrostis Jnnceus by Elliott.
