THE AMERICAN BOTANIST 99 



can furnish the following information taken from actual tests 

 in the field : Coruus florida has a pleasing, sweet, well defined 

 fragrance. Eupatorium purpurewm is moderately fragrant. 

 Amelanchier Canadensis has a pleasing odor. In some speci- 

 mens I found it quite noticeable, in others rather faint. Rhus 

 glabra, especially when growing in open sunlight, is quite fra- 

 grant. Asclcpias tuberosa and Dicrvilla trifida are not fra- 

 grant. I find it a general condition that fragrant flowers of 

 the same species are more fragrant when growing in sunlight 

 than when growing in shade." 



Miss Caroline G. Soule adds Galium asprclluin to the list 

 of fragrant species and says: "I put a spray of Galium 

 asprclluin out of my room last evening, it grew so sweetly 

 fragrant after sunset, no odor being noticeable earlier though 

 it had been in the same place all day." Without knowing the 

 species in question the editor questions whether it was the 

 flowers or the foliage that was sweet-scented. Galium triflorum, 

 a closely related species, is sometimes called sweet scented 

 bedstraw because the foliage is fragrant in drying. We hope 

 later to publish a list of plants with sweet scented parts other 

 than flowers. Many such plants have a disagreeable odor 

 when fresh, the sweet clover for instance, but develop much 

 fragrance as they dry.
