STATUS OF EPILOBIUM ALPINUM AND EPILOBIUM 
HORNEMANNI. 
ALBERT HANFORD MOORE. 
While studying the alpine willow herbs from the White Mountains 
in connection with a flora of Coós County upon which Prof. Arthur 
Stanley Pease and the writer are engaged, [ found that they presented 
a number of problems about which the widest differences of opinion 
have existed, the solution of which was by no means simple. 
The opinion advanced, and I believe originated, by Haussknecht, 
that the seeds of Epilobium alpinum L. and E. Hornemanni Reichenb. 
are different, has been generally accepted since the publication of his 
monograph. He says of the seeds of К. lactiflorum Hausskn., by 
which name he calls E. alpinum, "testa glabra, lacunoso-impressa,”” ! 
but of the seeds of E. H ornemanni he says, “testa tenuiter papillosa.” ? 
Trelease in his Revision of the Genus Epilobium ? accepts this view 
! Haussknecht, Monographie der Gattung Epilobium, 158 (1884).
