MISSOURI BOTANICAL GARDEN 



* Spicata. 





[P. 72] alopecuro- spica tereti, involucris setaceis basi ciliatis 



deum 1 . f asciculatis unifloris flosculo quadruplo 



longioribus. 



No specimen.

and Pursh cites it under P. verticillatum Willd. It is 

 probably a Setaria and would naturally be one of the 

 common species in the Carolinas. He describes only 

 two species that can be referred to Setaria, the other 



o 



P. itaiicum. 8. qlauca and S 



common. The description states that the bristles are 

 four times longer than the flower, which applies better to 

 Setaria imberbis R. & S. (P. imberbe Poir.). P. alo- 

 pemrodeum L. is an Old World plant, but Linnaeus' 

 description is used by Walter.* 



itaiicum 2. spica composita, spiculis glomeratis setis 



immixtis, pedunculis hirsutis. 



No specimen. Probably correctly named as cited by 

 Elliott, Panicum itaiicum L., the description of which 

 Walter copies. 



hirtellum 3, spica composita: spiculis adpressis alternis, 



calycibus geminis: valvulis omnibus aris- 

 tatis: arista extima longissinia. Culmis 

 4-pedalibus erectis nee repentibus. 



There are three specimens in the herbarium: (1) A 

 panicle and upper leaf, the flowers long-awned, labeled 



* The descriptions were compared with those in the second edition of 

 Linnaeus 1 Species PJantarum, with which they agree more closely than 

 with those of the first edition. I have not observed that the descrip- 

 ions agree any more closely with those in the twelfth edition of the 

 Systema Naturae.
