2. S. coactilis Fernald in Rhodora, viii. 21 (inOG). — This species has been 

 well described by Fernald, and is as yet only kn<nvn from Penobscot County 

 in central Maine. I cannot add anything of value to Feniald's statements 

 except that according to my observations the i)edicel is only twice (not about 

 five times) as long as the gland as is also the case in typical .S. sericea. 

 Fernald says that " the shrill) of central Maine is in the shape of its cai)sule 

 and its distinct style as closely related to the arctic-aljjine Scdix argywcarpa 

 Anders, as to S. sericea.'^ Unfortunately the male plant of S. coactilis is still 

 unknown; it would be of great interest to ascertain whether tlie flowers have 

 one gland as in S. scricca or two as in S. argj/rocarpa. After all it seems to 

 me much more closely related to S. scricca than to the latter species.

This species was described in 1802 by the well-known English salicologist 

 J. E. Smith who published a good picture of it in 1803. At first he said 

 " this species has not been found wild in Norfolk, but was sent to ^Ir. Cro 

 by Mr. Dickson along with the last, as of British growth," while in 180,3 

 lie states; " for this new species of Salix we are obliged tv) Mr. Dickson who 

 found it in some i)art of Great Britain, the ex-.nct ])lace is not remembered, 

 and sent it In a growing state to Mr. Crowe. We only know the female 

 which is a small spi-eading tree." Pursh (1814) declared that " it has Injcn 

 by mistake adojjled as a native of Great Britain." Smith however in 1828 

 thought it possible that it might grow in Europe, and that the statements 

 that It had been found in Scotland " are not likely to beerronoou:;." Hooker 

 mentions the species iti 1835 but says, "I have never seen native .s])ee;mens." 

 Loudon who in 1838 quotes these different oiiinions says: " Mr. Borrer had 

 formerly both sexes growing at Ilenfield having r-x^:nvo I tho m i!e from Mr.
