Fani. XV. SCROPHULARIACEAE. 



64. Alectorolophus groenlandicus (Chab.) Ostf. emend. 



65. A. minor (Ehrh.) Wimm. c^ Grab. I hope to be able in another 

 place to treat tbe northern species of Alectorolophus minor, sens. lal. 



66. Bartschia alpina L. 



J. Landt in liis book on tbe Færoes (1801) mentions, tbat 

 Bartschia occurs in tbe Nortb-Stromo, but as no later investigator 

 had found it, and as tbe statements of tbe Rev. Landt are not al- 

 ways correct, I bad omitted it in my bst. Now I bave got evi- 

 dence of tbe correctness of its occurring in tbe Færoes, as botb 

 Miss Taylor and Mr. R. Rasmussen bave sent me specimens. 



Yaago: near Sorvaag (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 (I. c. pp. 55 — 56) I bave put down tbe result of my 

 examination of tbe Færoese Euphrasias, but I expressed some doubt 

 witb regard to tbe correctness of my determinations, as I must admit, 

 tbat tbe bmits betv^^een tbe small-flowered forms were arbitrary. I 

 bave taken up again tbe study of tbese interesting piants and bave 

 had a large material at my disposal, consisting of tbe collections 

 made by Mr. J. Hartz and myself in tbe Færoes in 1895, 1896, 

 1897 and 1903 togetber witb smaller collections from other investi- 

 gators. As some of the species in question have been described 

 upon specimens from Sbetland or Scotland, it was necessary to 

 have material from tbese countries for comparison. We have in 

 the Botanical Museum of Copenhagen a good many Eupbrasias from 

 Sbetland and Scotland sent me from my friend Mr. W. H. Beeby 

 and from the English monograpber of the genus the late F. Towns- 

 end, and furtbermore Mr. Beeby bad sent me all bis Sbetland- 

 Euphrasias on loan. I have therefore been able to decide several 

 points of interest, baving in my bands specimens from tbe original 

 locality and original collecting-date (»co-types« of the American bo- 

 tanists) of E. foulacnsis Towns., E. paludosa Towns. (= E. scotica 

 Wettst.) and E. horealis (Towns.) W^ettst.; besides tbe type speci- 

 mens of E. arctica Lange and E. gracilis Fr., f. atropurpiirea Rostr. 

 are in our herbarium. 



The following treatment will show, tbat the result of my ex- 

 amination is a reduction of the number of species. I think, tbat 

 it is because the authors bave had too scanty material at their di-
