island. Of the most interesting he emphasizes the following, of which 

 he says, that they have not previously been found on Disko: 



Ranunculus affinis, (this statement seems very doubtfiil to me^ 

 it is according to my opinion nothing but a form of R. nivalis). 



Draba alpina var. glabra. 



Cerastiiim latijolium^ without doubt a mistake for a form of C 

 alpinum. 



GnaphaUum sylvaticum (already reported by Hooker as collected 

 by Ly all); this species has never been found in Greenland, and Hart 

 must have mistaken a form of Gn. norvegicum for it, although he also 

 mentions this species^. 



Habenaria albida Br. Of this Hart says: i)Not recorded north of 

 64°14' by Lange, nor noticed by Brown, nor it is given in Walker's^ 

 piants of Greenland, nor in Durand's list of Kane's piants«. All these 

 statements are quite true, but as we have seen, this plant was already 

 1857 recorded from Disco by Hooker under the name of Peristylus 

 albidus (collected by Lyall). 



Listera cordata^ this was really found many years before on Disko 

 by Holboell, but the record of it was not published wlien Hart wrote 

 his paper. 



Dryopteris Linnaeana was already found here in 1870 and recorded 

 by Berggren in 1871. 



Of other Disko piants in Hart's list, the following deserve special 

 mention: 



Potentilla tridentata »common from Englishman's Bay to Point 

 Lakse«. This statement is most surprising, as no other botanist has found 

 it here, but H. G. Simmons has now informed us, (1. c. p. 470) that the 

 piants thus determined by Hart are really Sibbaldia procumbens. 



Andromeda polifolia; the record of this very rare southern plant 

 must also be due to some mistake (? Loiseleuria procumbens). Accord- 

 ing to Simmons (1. c. 472) no specimens are to be found amongst Hart's 

 collections. 



Riimex AcetoseUa, is somctimes found at Godhavn but as an in- 

 troduced weed. 



Arctagrostis lalifolia; according to my expericnce this statement 

 is erroneous, as this high-arctic species has not been found by other 

 collectors on the south coast of Disko, having its southern limit in the 

 Nordfjord (see my list). 



L. Kumlien, the naturalist to the Howgate Expedition of 1877 — 78,. 

 paid a visit of 3 weeks to south Disko: Godhavn and Disko-Fjord in 



* H. G. Simmons has come to the same conclusion and he reports that na 

 specimens of Gn. sylvaticum occur in the collections of Haut in the British 

 Museum or at Kew. (1. c. 472).
