2?+ THE GENUS CROCUS. 



Dardanelles. In 1877 I found it abundantly on the flanks of Olympus, above the 

 baths at Broussa at an altitude of nine hundred feet, and also at an altitude of 

 four hundred feet between Broussa and Gemlik (Gumehlik); but I can find no 

 records of its having been found much farther east in Asia Minor. On the European 

 side of the Bosphorus, Mr. Millengen gathered it near the sources of the Ayas-Agha 

 or Kiahathane river, a tributary of the Sweet Waters. It occurs also near Rodosto, 

 in Roumelia; near Adrianople; at Rhodopa (Rhodope Dagh?); and at Slivno, in the 

 Balkans; also near Babadagh in the Dobrudscha, its most north-eastern limit. 

 It has been recorded from Krajova (Crajova), in Wallachia, and Mount Grben in 

 Servia, its most western limit. It reaches its most northern range in Transylvania, 

 where it occurs on Mount Arasule, and Straschutz (Strasatz) mountain near Mehadia, 

 at Swinitza, likewise Schwarzoll in the Banat, and at Schwernsdorf. 



It has been naturalized near Montreaux in Switzerland, and in Barton Park, 



Suffolk. 



Crocus aureus occurs generally at low elevations, and the flowers are produced 



in February and March.
