382 APPENDIX. 



" Obs. A singular dwarf but robust species; in the only 

 specimen I have seen, (said by Mr. Say to present its ge- 

 neral aspect,) the culm is scarcely more than 12 inches 

 high, triangular above, and unusually thick for the height 

 of the plant j the leaves I have not seen. The involucrum 

 consists of three very unequal, rigid leaves, (when dry,) 

 striate and carinated, with blunt, attenuated points, the 

 longest exceeding the length of the umbell. The size of 

 the umbell, and the spikes which compose it, are remark- 

 al^ly large ; the number 7, upon elongated and nodding pe- 

 duncles of unequal length. Each spike measures about an 

 inch in length, and about the same in breadth. The scales 

 of the spike are ovate and acute, the seed elliptic-oblong, 

 and somewhat flatly quadrangular. It is in all probability 

 a distinct species.'^ (Mr. Nuttall.) 



6. LiMNETis glabra, Pursh. 

 Not rare. 



Hab. Prairies of the St. Peter. 



7. Agrostis brevifolia, Nuttall Gen. I. p. 44. 



8. Panicum elongatum, Pursh, I. p. 



This is the plant I have always designated by the above 

 name, finding it frequently in North Carolina.

9. Festuca spicata? Nutt. Gen. I. p. 72. 



I am not sure whether this is Mr. Nuttall's plant, but it 

 evidently comes near it. The specimens in the collection 

 indicate a larger size than he ascribes to it.

10. Bromus ciliatus, Linn. Willd. Spec. PI. I. p. 433. 

 See Elliott, Sketch, I. p. 173. 



This I think is the true ciliatus of Linnaeus, for, in the 

 present species, the margins only, and not the back, are 

 very hairy.
