188 Fr. J. Mathiesen. 



Alcohol material from Itivnek near Holsteinborg (E. Warming, 

 -*h 1884). Herbarium material from Umanak, Strømfjord, Isortok 

 and Itivnek in Greenland. 



Pax and Knuth consider that the small Primula from 

 Itivnek, described and illustrated by E. Warming (1886, a) 

 belongs to the species Pr. jarinosa, but as a special variety: 

 d, groenlandica (Warm.) Pax. The Greenland plants of this 

 species differ from Pr. stricta Hornem., (which latter accord- 

 ing to the above authors does not occur in Greenland; see 

 also Rosenvinge), by having deeper incised corolla lobes, 

 and by a calyx about the same length as the corolla tube, 

 whereas in Pr. stricta the latter is considerably longer than 

 the calyx (fig. 10). The relative length of the calyx tube 

 and that of the corolla seems, however, to vary somewhat, 

 not only in the true Pr. stricta, but also in the Greenland 

 form of Pr. jarinosa. No doubt, the plants from Itivnek 

 have the calyx as long as the corolla tube, but, amongst 

 about half a hundred specimens from various other places 

 in Greenland, I found only a few flowers exhibiting similar 

 proportions, the calyx being generally somewhat shorter. 

 The same has been observed by Abromeit, who writes 

 "die gelbe Kronröhre ragt etwa 2 mm aus den Kelch 

 hervor". According to this author the pedicels increase 

 greatly in length after flowering: "Die früher nur 2 mm 

 langer Blütenstiele verlangen sich nach der Blütezeit bis zu 

 10 mm, und an einer alten abgestorbenen Fruchtdolde konn- 

 ten gegen 24 mm lange Fruchtstiele gefunden werden". The 

 deeply incised corolla lobes were found in all the specimens 

 of this form, examined by me. Besides in South-West Green- 

 land it also occurs in Labrador, thus sharing the same geo- 

 graphical area with Pr, egaliksensis (ace. to Pax and Knuth). 



In vigorous specimens, the lower surface of the leaves 

 is mealy (Abromeit, Rosenvinge). 



The shoot-structure closely resembles that of the nearly 

 related species already described.
