﻿252 Farwell: Michigan Species of Polygonatum 



in course of pressing will burst open the buds so that they appear to 

 be matured flowers in the dried specimens. P. hirtiim, a species 

 with glabrous leaves, but with the upper part of the stem and the 

 peduncles hispidly pubescent, would also be sought here but 

 nothing answering to the description of either has been found in 

 Michigan. No intermediate forms have come under the author's 

 observation, i. e., none of the large-leaved, large-flowered forms 

 has had pubescent leaves or small flowers nor none of the small- 

 leaved, small-flowered forms has had glabrous leaves or large 

 flowers. There appears to be no intergradation between the 

 Puhescentes and the Glahrata; Walter's P. hiflorum is typical of 

 the latter and Pursh's P. pubescens, of the former.
