1909] Мооге, — Epilobium alpinum and E. Hornemanni 145 
Bo‘. x, pl. 707, 1826-1829 (a most excellent figure of E. Hornemanni) 
and the plate, Flora Danica ii, 322, already mentioned, but in the 
description he says, “‘kronbl. ....violettréda....ell. hvita” and adds 
"Den mer hógvüxta och uppriita formen med flere blr och oftast 
hvita аг var. Hornemanni (Reich. pl. crit. 2). + This confused 
account does not seem definite enough to deny or affirm the strong 
implication of the Annotationes, for the description of the species may 
well be intended to include that of the variety. The conception of 
the white-flowered element seems thus to be disposed of, and even if 
it afterwards proved that the Linnaean specimens really had white 
flowers, they are not type specimens in our modern sense, so that such 
a discovery could not be taken as controverting the strong evidence 
that Linnaeus had a purple-flowered plant in mind when he wrote. 
The field now lies between E. anagallidifolium Lam. and E. Horne- 
manni Reichenb. The description given by Linnaeus in the Species 
Plantarum, as in the Flora Lapponica, answers much better to that of 
the leaves of E. Hornemanni, than to that of the narrowly elliptic to 
oblong leaves of E. anagallidifolium. In the Species Plantarum, 
in addition to the doubtful Scheuchzerian name, is cited the name 
Epilobium foliis ellipticis, obtuse lanceolatis Haller Enum. Meth. Stirp. 
Helv. Indigen. 1, 408 (1742). Haller writes of it as follows: Folia in 
rarioribus conjugationibus, ima ovata, superiora longiusculo mucrone 
in obtusam ellipsin attenuata, brevibus denticulis serrata. Flores... . 
petalis dilute purpureis....? From this it is evident that E Horne- 
manni was included,* and if E. alpinum L. really is a mixed species, 
it depends for that character upon the reference to Scheuchzer. It 
would be very satisfactory to be able to remove this objection as well, 
but unfortunately Scheuchzer's work is not at hand. However, 
according to the so-called doctrine of remainders, which has been 
generally accepted and which, though it finds no adequate expression 
in the Vienna code, seems to be undoubtedly included in it,® the name 
E. alpinum must stand for E. Hornemanni, since the latter and its

2 In Е. anagallidifoltum, too, the leaves are almost alike, whereas іп E. Hornemanni 
the upper leaves tend to be more attenuate than the lower.
