Dicotyledonese. 
Salicaceae, Briss.-Mirb, 
68. Salix chlorophylla, Anderss. 
8. phylicifolia, Macoun, Contr. Canad. Bot. 
Distribution. [Nottingham (NHM), and Mansfield Islands, Bell (ex Macoun, 
Cat.)]; Baffin Land: Upper Savage Islands, Bell {ex Macoun, 1. c). 
Geographic area. Northern parts and mountains of North America. 
The specimen from Nottingham Island which I have seen in the NHM is 
rightly identified as far as I am able to judge, and therefore I tiiink I am justified 
in eiitering the species for the Archipelago. J. M. Macoun has, indeed, låter changed 
Ihe nanie for that of S. phylicifolia, hut as it seems not with the intention of reducing 
the species of Andersson to a variety of the Linnean one. But if it shall be upheld, 
1 think it is better to follow its author and look upon it as the american substitute 
for the nearly alHed S. phylicifolia, L., of Eurasia, which is entirely wanting in 
America and hardly aretic anywhere. The range that Andersson (in de Candolle, 
Prodr. XVI, p. 243), as well as Macoun (Cat., p. 446) give to S. chlorophylla, makes 
it rather probable that it should occur in Labrador and Baffin Land, as it is princi- 
pally distributed in the eastern parts of the Continent, where it goes southward to 
the White Mountains. 
69. Salix Richardsonii, Hook. 
Distribution. Victoria Land: Minto Inlet, Andersson (KH), south coast, 
Rae (KH). 
Geographic area. Western aretic and subarctic parts of America. 
70. Salix alascensis, (Anderss.) Coville. 
Distribution. Banks Land, M'Clure (KH), Anderson (ex Armsironö, 1. c). 
Geograpliic area. Western aretic and subarctic parts of America. 
I have only seen a single specimen from our area in the Kew herbarium, and 
it was in a rather young state, but it was without doubt to be referred to this 
beautiful and well defined species. The first name, S. speciosa, given by Hooker 
& Arnott in Bot. Beechey, 1832, unfortunately cannot be upheld, because there 
exists a somewhat older homonym. Coville therefore in his exellent treatment of 
the wiUows of Alaska has taken up a name, estabhshed by Andersson (in de 
Candolle, Prodr.) for a variety of it. About the occurrence of this Andersson 
says (1. c, XVI, p. 275): »Tn Alaxa Ameriese occidentali-borealis (Kostalsky)*. 
That »Alaxa» stånds for Alaska there can be no doubt about, either the russian
