THE GENUS CROCUS.

Arize; Aneon, near Luchon; and at the Port de Venasque; also on the Camgou, 

 longitude 2° 35' east, near the eastern end of the Pyrenees. 



The same narrow belt of distribution, nowhere more than a degree and a half 

 wide in latitude, continues to the Rhone through Southern France, in the Cantal, 

 Lozere, the Haute Loir, on Mount Mezenc; at Vals in the Ardeche, and at Lanujol 

 and Dourlises in the Gard. 



East of the Rhone the latitude of its distribution widens, and it occurs 

 o-enerally in the Alps of Dauphine, and the Pine region of the Jura: also in the 

 Maritime Alps, on the Col de Tenda, and in the Forest of Mains; but in this district 

 it does not approach the coast line, where C. versicolor seems to replace it. It is 

 extremely abundant on Mont Cenis, where it occurs in endless variety of colouring 

 and marking, up to an altitude of about seven thousand feet. It is generally dis- 

 tributed throughout the Swiss Alps, on Mount Pilatus, the Wengern Alp, Murren, 

 above Zermatt, etc.; also in the Tyrol, Carinthia, the Bavarian Alps, Southern 

 Austria, in the Valley of the Erlaf and as far north as Zavelstein in Wurtemberg. 

 It extends to the north-east as far as the Carpathians, where Wahlenberg, in his 

 Flora Carpatica, records its occurrence in sub-alpine meadows near Langewald, 

 Kalkgrund, Djumbier, etc. It is said to be found in Istria, and in Dalmatia it 

 occur! up to a height of four thousand feet, at Koziah and Markesina Greda. In 

 Carniola it occurs on Monte Wanas at an altitude of four thousand six hundred 

 feet; also in the neighbourhood of Trieste, where at Opsina (Opschina), at an altitude 

 of nine hundred feet, the diminutive variety, albiflorus of Gay, is abundant, and it 

 is also said to extend up to an altitude of three thousand feet. Herbert records a 

 variety from the Steppes north of Odessa, but this Trautvetter thinks is an error; 

 and there is no authentic record of its occurrence further east than the Carpathians, 

 longitude 23° east. The records of its occurrence in Bosnia and Servia may refer to 

 the & nearly allied species, C. Tommasinianus of Herbert, though it is not improbable 

 that C. vermis also grows there. 



In Italy it is generally and widely distributed, at both high and low elevations, 

 from the sub-alpine districts of Piedmont and Lombardy, throughout the Apennines 

 to Sicily. It has been recorded from the Eastern Riviera; from Oldenico, near 

 Vercelli in Piedmont; from Tuscany, at Pratolino and Monte Senario near Florence; 

 also from the Pontifical States. The large purple variety which grows abundantly 

 on the upper terraces of the Botanical Garden at Rome has all the appearance of 

 being indigenous. In the Neapolitan States it occurs at Frasso, near Caserto; and 

 on Monte Morone, Monte Sirrente, Monte Tittone, and Monte Spenta in the 

 Abruzzi; at Castelgrande in the Basilicata, and on Monte Pollino in Calabria. 



In Sicily the diminutive form, C. siculus of Tineo, occurs on the mountains in 

 the north of the island; on the Madonna Serra del Soglio, Monte Soro, at Caeca-
