FLORA OP VERMONT 105 



P. dichotomum, Linn. These plants represent the var. viride, Vasey, 

 a form considered as P. dichotomum, L. by common consent since they 

 correspond more nearly than any other form to the original description 

 of the species. 



For P. pubescens read P. unciphyllum, Trin. This is one of the com- 

 monest species of this group. Professor Rcribner sends the following 

 statements as to the synonymy : 



" Panicum pubescens of recent authors, not Lamarck. Recent ex- 

 amination of the type of this species in Lamarck's Herbarium, Museum 

 de Historie Naturelle de Paris, proves it to be the late branched form 

 of Panicum scoparium, Lam., which is entirely different from the form 

 so considered bv American authors and is Panicum viscidum, Ell. 

 Synonomy : Panicum scoparium, Lam. Encycl 4:744, 1797. (Panicum 

 pubescens, Lam. 1. c. 748; Panicum viscidum, Ell. Sk. Bot. S. C. and 

 Ga. J : 123, 1817.) See Bull. 24, U. S. Dept. Agr. Div. Agros. 



For the form previously referred to Panicum pubescens we have 

 taken up the name Panicum unciphyllum, Trin. Gram. Pan. 242, 1826. 

 Our reason for taking up this name is this — in the Herbarium of Col- 

 umbia University is a specimen referable to the form here taken up as 

 P. unciphyllum, labelled in Torrey's handwriting "Panicum unciphyl- 

 lum, Trin. in lit." which was evidently named by Trinius and more- 

 over the specimen agrees with Trinius', description. It is of course pos- 

 sible that this plant may not be the same as the type of Panicum unci- 

 phyllum, Trin., but we feel justified in taking up this old name for the 

 species in question, rather than applying a new name to this very 

 common grass." 



P. sphaerocarpon, Ell. Erase this name. The plants collected on 

 Sterling Mountain are a peculiar form of P. boreale, Nash. 



P. tsugetorum, Nash. Erase this name. The plant so referred is 

 P. lanuginosum, Ell. (P. Tennesseense, Ashe.) The record, "Burling- 

 ton, Jones," should therefore be transferred to P. lanuginosum.
