SOME ALGAE FROM MERANO

The Alga-flora of the district surrounding Merano is largely 

 unknown. In the treatise by K. W. v. Dalla Torre and Ludwig 

 CouNT Sarnthein there are only a few scattered details of Httle 

 value. 



During the autumn 1921, I visited Merano for some six weeks, 

 and made a few collections of Algae. The conditions for the 

 growth of Algae are rather unfavourable, as there is only a single 

 occurrence of stagnant water. This is a small tarn at the Vigil- 

 joch, about ten minutes from the S. Vigilio church, at an altitude 

 of more than 5700 feet. 



The tarn is a small and shallow sheet of water, parti}' with 

 boggy margins, and is situated in spruce forest. The geological 

 formation is marble-stone. 



In the brooks and rivers near Merano there is a conspic- 

 uous vegetation of Cladophora and some Myxophyceae. 



On the whole, collections were made from three difterent 

 places, viz. from S. Vigilio, especially in the tarn, from brooks 

 near Castle Goyen, and on trunks of various trees near the view- 

 point in the Gilf, such as, Cedrus Deodara, Sequoia gigantea, 

 Fraxinus ormts, Gymnocladus dioica. 



Finally, I will cali attention to the fact that in the vicinity 

 of the lìeighbouring town Bolzano there are several lakes, which 

 would no doubt prove interesting, especially if compared with 

 lakes north of Brennero.
