92 FIRST JOURNEY IN EUROPE. [1839, 



and I assisted him in arranging them and selecting 

 for his herbarium ; in the course of which I have 

 obtained specimens of nearly all the Northern and 

 Oregonian ones, including one or two which have 

 come in recently, of which I have, when there were 

 duplicates, specimens also for you. The return num- 

 bers of those sent you were in many cases strangely 

 misplaced, and Boott has often been sadly confounded. 

 He has studied the genus very critically, hypercriti- 

 caUy I may say; for he makes new species where we 

 should think there were too many already. "We went 

 over Hooker's Grasses in the same way, and I have 

 obtained numerous specimens and much useful infor- 

 mation which we shall presently require. On Christ- 

 mas day Joseph Hooker selected from a large Van 

 Dieman's Land collection a suite of specimens as far 

 as they have been studied (to Calyciflorse), in which 

 there is in almost every instance a specimen for each 

 of us. . . . 



In looking over the recent collections from the 

 Snake country, and Douglas's Californian, I recog- 

 nized a great portion of Nuttall's, ^ but by no means 

 all. There was a single specimen of Kentrophyta in 

 excellent fruit; another of Astrophia, with neither 

 flower or fruit, collected long ago by Scouler and 

 mixed in with a species of Hosackia, to which genus 

 I am not sure that it is not nearly allied. Nuttall has 

 made too many Hosackias ! The copy of " Flora," 

 with my notes, has gone round to London, so that I 

 cannot now communicate many curious things noted 

 in the second part. But how did we overlook the

 to the United States in 1807. His writings are intimately connected 

 with the development of North American botany.
