hydrophytic conditions in the abundance of Chelone glabra and 

 Eiipatorium perfoliatum. The ridges lack these species and are 

 distinctly mesophytic in character. All parts of the valley are 

 well shaded by Acer saccharum, Acer spicatum, and other trees 

 and shrubs. Aconitum novehoracense lives, so far as we observed, 

 only on the ridges, which it shares with a dense growth of Riihiis 

 odoratus, Monarda didyma, Arisaema triphyllum, Onoclea sen- 

 sibilis, Osmorhiza longistylis, Solidago flexicaulis, and unidenti- 

 fied species of Hydrophylliim and Thalictriim. Blooming plants 

 of the aconite rise approximately to the general level of these 

 herbs. Beneath them, and consequently in still denser shade 

 and subject to still greater competition for space, the seedling 

 aconites are mingled with Mitella diphylla, Viola scabriuscula, 

 and Fragaria virginiana. 



It is probable that search over other parts of the valley, 

 especially in the blooming season will reveal numerous other 

 plants of this rare species, which, however, shows no indication 

 of being in danger of extinction.
