32 Geographical Distribution of Plants. 



Two perennial species, one the C. Scouleri of Hooker, named 

 after Dr. Scouler of Glasgow, who accompanied Douglas on his 

 first voyage to the Columbia, and the other the C. monophylla of 

 Nuttall, are confined to the northwest coast. The C. Scouleri is 

 plentiful at the confluence of the Columbia with the Pacific, and 

 extends in shady woods along the coast. If it be the same as the 

 C. pamoioe folia of Siberia, why should it not also be found 

 at the Russian settlements towards Sitka ? Has the question as to 

 the identity of these two plants been yet determined ? The Cory- 

 dalis macrophylla has been passed over by Douglass as being the 

 same as the C. Scouleri. I know for a certainty he explored re- 

 peatedly the Wahlamet woods and prairies, especially about the 

 falls, where the city of Oiegon has since been founded, and he 

 must have observed such a plant growing in abundance in that 

 vicinity. If it be specifically different from the C. Scouleri, we are 

 indebted to Mr. Nuttall's discrimination for an addition to the 

 original American stock of this elegant genus. 



Lindley in his list gives fifteen genera to the order Fumariacese, 

 but only the three that I have gone over belong to North Ame- 

 rica. The Corydales take a much more extended range than the 

 Dielytrpe, and choose also more rocky ground. With them I close 

 my remarks upon the first family or alliance of the large group of 

 albuminose plants, — the Ranales of Lindley, from which he 

 excludes the Sarraceniaceae. I believe, however, that whatever 

 relation Sarracenia as a genus may hold to other plant?, its posi- 

 tion as chosen for it by Torrey, between Nympbasaceaa and Papa- 

 veraceaB, will by most people be considered correct.

It is some compensation for the absence of regular reports of 

 progress, caused by the occupation of Sir W. E. Logan with the 

 exhibition of Canadian products in Paris, to find the accumulated 

 reports of several years now issued in a respectable volume, with 

 an amount of elaboration and illustration giving them a much 

 more readable and permanent character than that which usually 

 attaches to reports of progress. The present report is in effect a 

 treatise on several important parts of the geology of Canada, illus- 

 trated with valuable and accurate maps, and embracing not only 

 the usual accounts of the progress of the survey, but systematic
