The remaining species, P. Tiyperborea, I have never seen, but the 

 description given by Bonaparte does not apply to P. obscura. All of 

 these doubtful species are from the north-west coast. 



List of the Plants collected at Akticosti and the 

 MiNGAN Islands during the Summer of 1861. By A. E. 

 Verrill. 



Owing to the numerous demands upon our time during the whole 

 summer, the collection of plants did not receive so much attention as 

 it deserved. Indeed, it often happened that collections that had 

 been made were left in the botanical boxes until spoiled, for want of 

 time to press them. The grasses, sedges, mosses and ferns were 

 almost entirely neglected. But since there are some very interesting 

 plants in the collection, and others which have not been previously 

 obtained in that region, I have been induced to prepare the following 

 list, incomplete as it is. 



In the identification of many of the most difficult species, I have 

 received much assistance from Mr. J. T. Kothrock, a student with 

 Prof. Gray, while some of the most doubtful forms have been ex- 

 amined by Prof. Gray himself 



The collection, like those in other departments, was made jointly 

 by all the members of the party. 



The only list of plants from Anticosti that has been published 

 before, of which I am aware, is that of the plants collected by J. 

 Richardson in 1860 ; published by B. Billings, Jr., in the Annals of 

 the Botanical Society of Canada, Vol. i., Part i., page 58. In that 

 list there are 37 species enumerated, nearly all of which are in our 

 collection. Kalmia latifolia is given, probably by some error, instead 

 of K. angustifolia, which is common there. 



All of the species in the following list are common at Anticosti, 

 unless otherwise stated. The dates refer to the time when they 



were first found by us in flower.
