66 OTTO VERNON DARBISHIRE, (Schwed. Südpolar-Exp. 



I think some remarks may be added here about the supposed occurrence of 

 Usnea Taylori Hook. (= Neuropogon Taylor i Nyl.) on the antarctic continent. 

 The specimen brought back on the "Southern Cross" (BLACKMAN Ant. p. 320) and 

 sent to the British Museum has already been found to be Neuropogon melaxanthum 

 Nyl. (DarbiSH. Nat. Ant. p. 7). Til. Fries judging from photographs only says 

 concerning probably specimens of the same species also of the same Expedition: 

 "Quam ad certain speciem referre, non Hauet. Usneae (Neuropogonis) speciem sine 

 dubio représentât, vix tarnen U. sulp hur earn, potius U. Taylori HOOK. FlL., qui hanc 

 speciem in Kerguelens Land abunde cresceute/u invertit." (Th. Fr Lieh Ant. p. 209.) 

 This is not I consider sufficient proof that the species Taylori does occur in the Ant- 

 arctic. Its occurrence is again reported for the Antarctic by SCHENK who of course 

 only quotes Blackman and Fries (Schenk Kerg. p. 172). Schenk also depicts 

 Neuropogon Taylori Hook. FlL. and melaxanthum ACH. (SCHENK Kerg. p. 41). The 

 figure illustrating the former (fig. 20 a) is I think most certainly correctly so named. 

 But with regard to the latter (fig. 20 b) I have my doubts and I almost think that it 

 really represents Neuropogon trachycarpum Stir I'. But we are here not really con- 

 cerned with these two figures as they represent plants of Kerguelen. I do think- 

 however that for the present Neuropogon Taylori must not be looked upon as an 

 antarctic plant.
