PROFESSOR GEEENE'S MISSION IN EUROPE. 165 



A large number of the new species collected by Douglas 

 were figured in the BotaoiqaJ Eegister or Botanical Magazine 

 and in systematic works. These figures were drawn IroBj 

 herbarium specimens, or moie. often from living plants grown 

 from seed sent from America. In such cases the identificBt- 

 tion is certain or rendered less difficult., But not aKi, wei:e 

 figured or fully described^ and it is probable that an examina- 

 tion of the types of Douglas will reveal mucti tlj&.t i§ 

 interesting and result in unexpected changes. 



This work will have lasting value; and for the task it i^ 

 evident that acquaintance with, our array of ?aQific Coast 

 forms must be extensive and detailed, nay, even minute; tha.t 

 experience in tlie field and herbarium skQuld, have been pro- 

 longed, and that a natural ability as a systematist, should 

 have been cultivated to a high degree. 



Professor Greene's first acquaintance with the Paci^Q 

 Coast flora was made twenty years siftce. In 1874 he made 

 an excursiorj through the Coast Kange from Vallejo to the 

 Geysers, Among other things he discovered ojk tfeat g^c^r- 

 sion SeneoiQ GreeVi^i, ColUnna Qr^en^i and Solanoa purr 

 purascen^. From the time of that early expedition np 

 attempt will be made to review his field work or literary 

 labors. It is sufficient to record that thereafter his interest 

 was chiefly in the Californian flora. To its elucidation he 

 brought with him knowledge and experience of a useful 

 kind acquired in residence and travel in nearly every part of 

 the United States. As the years passed qr, he quickly 



acquired cumulativQtestimopy of, the complexity of the Coast 

 Bange flora— the region touched by the early collectors. 

 Likewise came uncertaintiea. Studious attempts to make out 

 what were some of the first described species showed that it 

 would be impossible without the original specimens. That a 

 safe starting point might be had and the way thence- 

 forward sure and clear — but one thing remained. The eye 

 turned toward Kew, the lilecca of systematic botanists, and 

 toward Paris and Berlin, lesser Meccas. Wherefore tjhis 



pilgrimage. — W. L. J.
