Fam. XV. SCROPHULARIACEAE. 
64. Alectorolophus groenlandicus (Chab.) Ostf. emend. 
65. A. minor (Ehrh.) Wimm. & Grab. I hope to be able in another 
place to treat the northern species of Alectorolophus minor, sens. lat. 
66. Bartschia alpina L. 
J. Landt in his book on the Faeröes (1801) mentions, that 
Bartschia occurs in the North-Strömö, but as no later investigator 
had found it, and as the statements of the Rev. Landt are not al- 
ways correct, I had omitted it in my list. Now I have got evi- 
dence of the correctness of its occurring in the Faeröes, as both 
Miss Taylor and Mr. R. Rasmussen have sent me specimens. 
Vaagö: near Sörvaag (sent to R.R. from a relative, Mr. Niclas Ras- 
mussen, but without more exact indication of the locality); Vid.: rock- 
ledge on Mornefjæld, ab. 300—400 M. (E.T.). 
In my list (1. c. pp. 55—56) I have put down the result of my 
examination of the Færoese Euphrasias, but I expressed some doubt 
with regard to the correctness of my determinations, as I must admit, 
that the limits between the small-flowered forms were arbitrary. I 
have taken up again the study of these interesting plants and have 
had a large material at my disposal, consisting of the collections 
made by Mr. J. Hartz and myself in the Faröes in 1895, 1896, 
1897 and 1903 together with smaller collections from other investi- 
gators. As some of the species in question have been described 
upon specimens from Shetland or Scotland, it was necessary to 
have material from these countries for comparison. We have in 
the Botanical Museum of Copenhagen a good many Euphrasias from 
Shetland and Scotland sent me from my friend Mr. W. H. Beeby 
and from the English monographer of the genus the late F. Towns- 
end, and furthermore Mr. Beeby had sent me all his Shetland- 
Euphrasias on loan. I have therefore been able to decide several 
points of interest, having in my hands specimens from the original 
locality and original collecting-date (»co-types« of the American bo- 
tanists) of E. foulaénsis Towns., E. paludosa Towns. (= E. scotica 
Wettst.) and E. borealis (Towns.) Wettst.; besides the type speci- 
mens of E. arctica Lange and E. gracilis Fr., f. atropurpurea Rostr. 
are in our herbarium. 
The following treatment will show, that the result of my ex- 
amination is a reduction of the number of species. I think, that 
it is because the authors have had too scanty material at their di-
