confined to the single season of 1825. During April and May he collected 

 with Douglas mainly at the mouth of the Columbia and at Fort Vancouver." 

 The type, of which I saw fragments and a photograph from Herb. Kew, 

 has almost ripe fruits and young leaves. It probably has been collected 

 in the beginning of May. Barratt also cites specimens of Tolmie from Van- 

 There Is one from Barratt's herbarium in Herb. G. It consists of 

 a fragment of a branchlet with female flowers and very young leaves, and of

a male fragment which belongs to S. siichensis. In the original diagnosis of 

 S. Scoidcriana the leaves, too, have been described but apparently there is 

 no sterile type or co-type with mature leaves in existence, and Andersson 

 states (1858) : " in herbario Hookerii vidi specimina duo florentia ad S. 

 hrachysiachjam Benth. absque ullo dubio pcrtinentia, et specimen S. sit- 

 chensis Sans." In 1867 he says, that these three specimens are " in una 

 eademque charta agglutinata." The photograph before me only shows a 

 specimen collected by Scouler which I regard as the tj^pe. The description 

 of the leaves in Hooker's Flora certainly fits those of S. sitchensis; Barratt, 

 therefore, must have had a specimen of this species with mature leaves which 

 has been lost. Piper remarks that " Barratt's original types seem to be lost." 

 Andersson, in 1858, rejected the name *S. Scouleriana because it is 

 founded on two different species. There is however no reason to suppress 

 the name, as the female specimen represents a good species. There is a 

 possibility, already mentioned by Piper, that Scouler only collected a fruit- 

 ing specimen, and that the mixture with sitchensis is due to Tolmie's plant 

 of which I have spoken. Barratt and Hooker do not describe male flowers, 

 and probably they have not seen Tolmie's male specimen or recognized that 



it belongs to a different species. 



S. Scouleriana sensu stricto was described again by Nuttall in 1843 as

The young 



leaves partly show a thick flavescent* opaque tomentose pubescence on the 

 lower surface but appear to become later rather glabrous. They are oboval 

 but the apex Is wanting. The small leaflets of the fruiting ament are almost 

 glabrous above and flavescent-silky beneath. The other fragment with 

 mature leaves which are almost glabrous and brownish beneath might be 

 taken for a co-type of NuttaU's second species, S. stagnalis. The oboval 

 leaves measure up to 4 :2 cm. The twigs of the season are finely pilose, the 

 one year old branchlets glabrous and purplish. The type oijlavescens came 

 from the Rocky Mountains while that of stagnalis was collected on " the 

 banks of the Oregon " Columbia. There is another specimen In Herb. G. 

 collected by Nuttall " Columbia-woods," and named '* Salix cinerea * lajo- 

 pus.'' The name cinerea has been crossed out later, and above it is written 

 Hookeriana Barratt. This seems to be S. Hookcriana Nuttall (Sylva, p. 64) 

 sensu stricto. The specimen has folia utraque acuta, ad 10:7 cm. magna.
