native site is not yet ascertained. ‘The autumnal white C. 
Boryanus of Cephalonia, Modon, and Navarin, appears to 
. differ in little but its season of flowering from lagenzflorus, 
but I have not yet seen it alive. 
The southern limit of the genus runs near lat. 35°, 
from Tangiers by Malta, Candia, and Cyprus to Aleppo; 
there it turns northward, following, I believe, the right 
bank of the Phrat to its source between Erzerum and 
Trebisond, and from thence it passes between Kurdistan 
and the Caspian, as far S. as Tabriz, not descending into the 
plain of the Tigris and Euphrates, and is cut off from the 
southern shore of the Caspian and from the rest of Persia. 
Mr. Kotschy found a blue Crocus, (cancellatus) in Syria and 
near Tabriz, and a white one, probably Boryanus v. Caspicus, 
near Baalbec and Tabriz. I have lately learned from two 
quarters that the yellow Crocus follows Mount Lebanon 
southwards from Aleppo and approaches Damascus on the 
hills, where it is eaten by the natives, who make a pala- 
table dish of it; but it cannot cross the Euphrates, and 
the alluvial plain of Damascus. The genus is stopped to 
the north of the Caspian by the Volga and the salt plains. 
C. sativus is a cultivated plant in Cashmere, and the Crocus- 
like plant of Suleimania seems to be a Merendera or Col- 
chicum. 
There are yet some vernal races in the Levant; one 
C. Fleischerianus on the hills near Smyrna, white-streaked 
with finely interwoven fibres, and seemingly in some de- 
gree akin to C. reticulatus albicans ; C. Sieberianus (named 
more happily, but later, nivalis by Bory St. Vincent) on 
the very summits of Crete and Taygetus, flowering between 
patches of snow, at the height of above 6,000 feet on the 
latter in July; C. nivigena, allied to it, on the steppes near 
Odessa, which have both finely reticulated coats like C. ver- 
nus, attached at the base instead of the brow of the bulb, and 
differing in other respects ; and lastly, C. nubigena, from the 
summit of Gargarus, (with a hard smooth coat, and at the 
base a ciliated ring, as in C. pulchellus) closely allied to C. 
Sibthorpianus of Cretan Ida, and seemingly to C. levigatus of. 
the summit of Milo and Thermia as well as Crete, which has 
a hard coat, cut at the base into the appearance of scales. As
