oldest synonym E. nutans Hornem.' were both described later than 
E. anagallidifolium Lam. or E. alsinefolium Vill.; in other words 
it alone is left after the supposed conflicting elements have been re- 
moved. Now taking up the synonymy which Haussknecht gives for 
his E. lactiflorum; E. alpinum L. and E. nutans Hornem. have already 
been discussed. E. alpinum L. 8. fontanum Hornem., not Wahl., is a 
pure synonym of E. nutans, having been based directly upon it without 
any accompanying description. (Under E. alpinum L. var. fontanum 
Wahl. Flora Lapponica, 95 (1812), the author cites as the first synonym 
E. alsinefolium Vill? ‘This, as far as one can tell without going deeply 
into the matter, is a purple-flowered species of Europe, and certainly 
as far as the plate is concerned it is a very distinct species.) E. 
alpinum L. 8. majus Wahl. Flora Suec. i, 234 (1824) is also founded 
on Е. alsinefolium (and hence is purple-flowered). E. origanifolium 
Lam. y. intermedium Lindbl. Physiogr. Tidskr. 1838, is a reference 
given by Haussknecht. ‘The periodical appears to be a very rare one, 
but an article оп Epilobium by the same author occurs in Flora.? 
According to this, Lindblom's variety is based on E. alpinum L. y. 
nutans Hartm. Handb. Skand. Flor. ed. III, 91 (1838). (Here is cited 
again Svensk. Bot. x, pl. 707 and Flora Danica, ii, 322.) E. alpinum 
L. var. majus Fr. Novit. Fl. Suec. Mant. ii, 20 (1839) is the only name 
remaining to be considered. In a note Fries says, “in var. majori 
semper lacteis." Here then for the first time is a mention of white 
flowers, but the only synonym given is E. alpinum L. y. nutans Hartm. 
which, as we have just seen, has purple flowers. There seems there- 
fore to be no available name for the white-flowered plant except 
E. lactiflorum Hausskn. 
For convenient reference, I give below the correct names of the 
two plants with a summary of their more important synonymy. 
EPILOBIUM ALPINUM L. floribus inter lilacinos et purpureos varianti- 
bus.— Sp. Pl. ed. I, 348 (1853); Flora Dan. ii, pl. 322 (1766); Svensk. 
Bot. x, pl. 707 (1826-1829); Sowerby Engl. Bot. xxviii, pl. 2001 
(1819); Hartm. Annotat. Plant. Scand. Herb. Linn. (ex Act. Reg.

! E. Hornemanni Reichenb. Iconogr. Bot. seu Plant. Crit. ii, 73, pl. 180, f. 313 (1824) 
was based on E. nutans Hornem. Flora Danica, viii, pl. 1387 (1810) which is an illustration 
of a plant with lilac flowers, in all respects resembling our common alpine species. It is 
interesting to note that the Index Kewensis correctly includes E. Hornemanni as a syno- 
nym of E. alpinum.
