plant from Roumelia, confounded with C. speciosus in Sir 
W.J. Hooker's herb. I requested that search might be made 
for it in the forest of Belgrade, where I thought it likely to 
grow, and there it was found in flower without any leaf in 
October. It differs from all known Croci in having white 
anthers and pollen. The filaments are also remarkable, being * 
yellow and hairy. C. longiflorus is a native of Italy and Sicily, 
and flowers with us in October, or sometimes later, the leaf 
accompanying the flower, which is very fragrant, of a pale red- 
dish lilae, with the tube yellowish and the throat of very deep 
yellow. It is closely akin to C. odorus of Mt. Verdala in Malta, _ 
whereof the leaves rather precede the flower, and which has the 
throat very much paler, and the sepals and tube striped with 
purple. C. Thomasianus has much affinity to C. sativus, and is 
a native of Italy. C. Cartwrightianus was obtained last summer 
from the Greek island Tino by J. Cartwright, Esq. and was 
before unknown. |t is evidently akin to C. Pallasianus. 
C. Pallasianus is found in Tauria, and said to grow also in 
the Cyclades, but is not sufficiently known and examined. 
The figure given is from a dry specimen found by Prof. 
Besser in Tauria, for the sake of comparison with C. Cart- 
wrightianus. 
This opportunity may be taken to give some general infor- 
mation concerning Croci. They grow naturally on high land 
between the Atlantic and the Caspian, north of the Mediter- 
ranean, one autumnal species being, however, found on the 
heights near Tangiers; and a vernal species was said to have 
been seen on Atlas by Desfontaines, whose confused and 
evidently erroneous description was taken from plants growing 
in the Jardin des Plantes, and no Crocus has been yet found 
by the French in Africa since their occupation of Algiers. 
C. Pyrenzus (afterwards ill-named nudiflorus by Smith) is 
found abundantly on the Pyrenees in September; and the 
kindred Asturicus, smaller, darker, a month later, and bearded, 
near Gijon and Santander. Whether they meet in Biscay 
and Navarre is not ascertained. They are distinguished from 
all others by a stoloniferous bulb producing its offsets at a 
distance. 1n the mountain' pine-woods of S. Spain, C. sero- 
tinus grows, flowering with us in November and December, 
the leaves beginning to accompany the flowers, and distin-
