ascending, or even almost erect on the stem. The inflo- 

 rescence which, if it were conformed to the habit of the plant, 

 would be broad and compact, is more elongated and open as 

 well as narrower than in [7. racemosum. The rootstocks are 

 thicker and have shorter internodes. It is particularly com- 

 mon in the California Coast Range, occupying higher ground 

 than its associate, U. sessUifoUum^ preferring less moisture 

 and a more clayey soil. Perfectly true to the Calif ornian 

 type it occurs as far eastward as Montana. 



Our fellow laborers in the field, especially the few of them 

 who have the happiness of working from year to year along 

 our northwestern or southwestern borders, should help us by 

 giving particular attention to thsse plants ; supplementing 

 good specimens (these so made as to show ripe fruits, and the 

 rootstocks also), by notes of habitat, hues of herbage, and 

 color of berries when fresh and fully ripe. The lines of 

 demarcation between some species are not yet sufiiciently 

 indicated, nor can they ever be well drawn by the unaided 

 efforts of the closet botanist. 



The Color Character. 



There is an aphorism of Linnaeus w^hich freely rendered 

 I'uns like this : Color in the same species varies greatly, 

 hence for the discriminating of them it is valueless.^ That 

 in many species the color, especially that of the flowers, 

 varies extremely is undoubted ; but it does not follow that it 

 ^ay not be in many others c[uite unvarying.' There is no

'Albino states are not here taken iuto account. There are perhaps 

 few species of flowering plants in which this freak does not occur. Yet 

 tliere are botanists who would recognize it, and give it a name in every 

 instance. These are probably iniaw^are how great is the number of
