20 THE PLANT WORLD 



Rhamnus Purshiana, Oregon Bearwood. — This tree is in no danger 

 on account of its flowers, which are rather inconspicuous, but the bark 

 is in such demand for medicinal purposes that a continuance of the prices 

 prevailing this season will result in the practical extermination of the 

 species within a few years. 



Cor?i7is Nuttallii, Flowering Dogwood. — The showy white involucres 

 of this species cause it to be indiscriminately gathered when in bloom, 

 but it is such a rapid grower that it eventually gets beyond the reach of 

 the destroyer, and, so far, it is not perceptibly diminishing except where 

 stricken by forest fires. It is being used as an ornamental tree in many 

 lawns but does not bear transplanting well. 



Among the numerous introduced species to be found in this locality 

 only the two following may be referred to here : 



Chrysanthemum Lejicanthemum , Ox-eye Daisy. — This hardy immi- 

 grant is to be found abundantly in bloom from March to July, and sparingly 

 so for about three months longer. It is gathered without limit by young 

 and old alike, but notwithstanding this it appears to be gaining ground, 

 if anything, owing to its rapid spreading over pastures and roadsides and 

 its rejection by stock generally. 



Centaiirea Cyanus, Bachelor's Button. — One of the prettiest of our 

 introduced plants, and considered a troublesome weed by farmers. It is 

 gathered in great quantities, but as it does not spread over pastures and is 

 easily destroyed by cultivation, it is steadily disappearing, except in 

 neglected fields. 



Portland, Oregon. 



Editorial. 



We extend to all present and prospective readers of The Plant 

 World a hearty New Year's greeting. With this issue our magazine 

 enters upon its seventh volume, and as we announced in December, we 

 have felt justified in slightly increasing the annual subscription price, for 

 reasons which will be apparent in the little sermon which follows. 



It is by no means an easy task to blow the editorial trumpet and to 

 convince our readers of our perfect sincerity. Still, any journal is ex- 

 pected to set forth its claims to patronage, or it would become difficult 

 for the public to select its reading matter intelligently. Our older readers, 

 of course, do not need to have the development of the magazine dis- 

 cussed, since they have only to compare the last volume with the first 

 and form their own judgment as to the extent of improvement. But 

 there are many who will be reading The Plant World this month for
