THE AMERICAN BOTANIST 



109 



CoNOPHOLis Americana. — Since the publication in this 

 magazine of the notes regarding the distribution of Conopholis, 

 we have received excellent specimens of the plant from H. C. 

 Bigelow, New Britain, Connecticut, who collected them at 

 Plainville, Connecticut, where they grew in dry rich woods 

 under chestnut trees. The plant is regarded as rare in the 

 state. 



Circassian Walnut. — Many of those who admire the 

 beautiful finish of rooms trimmed in Circassian walnut are 

 doubtless unaware that this is none other than the wood of that 

 tree whose fruit we know as the English walnut. The tree 

 grows naturally from the eastern slopes of the Caucasus to the 

 foothills of the Himalaya mountains in India and Burmah, but 

 has been extensively planted in other parts of the world. Much 

 of the w^ood used in America comes from the region near the 

 Black Sea. The demand for it is steadily advancing the price 

 and other woods are often substituted for it. Its near relative, 

 the familiar butternut [ Juglaiis cincra) has wood that closely 

 resembles it both in grain and color and red gum with a similar 

 grain is also occasionally used. 



Changeable Phlox. — Some mention has been made in 

 this magazine of a specimen of garden phlox in the editor's 

 grounds which changes color daily. Other specimens have 

 now been produced that change from deep purplish pink at 

 mid-day to violet-blue at dusk. Not all pink phloxes have this 

 habit as anyone may discover by visiting the nearest blooming 

 plants of this color, and those that do have it cannot be dis- 

 tinguished from the others at noon. As evening approaches, 

 however, the pink begins to fade and lavender or lilac takes 

 its place and these colors ultimately give way to a deep blue. 

 This color remains through the night and for some time in 

 the morning. When picked and kept in a poorly lig-hted room, 

 the blue color persists. From this fact it is easy to see that 

 sunlight in some way affects the color-changes. A\'hether me
