Corns large, rough, fibrous, roots 
' proceeding from all parts of the 
tuber. persicum , hedercefolium. 
There is a form of hedercefolium with a very distinct habit of 
tuber. The roots proceed from one part of the under surface, a 
little removed from the centre of the corm, whilst the growing 
point on the upper surface starts from a corresponding point on the 
opposite side of the centre, and this peculiarity is said to be constant. 
I have examined specimens, hut my personal knowledge of this 
variety is not yet sufficient to enable me to do more than allude to 
it at present. 
We now come to the leaves, of which there are four main 
variations in form and habit. 
I.—Round or reniform, 
Not marbled . 
Marbled on upper surface 
Sometimes inclined to be cordate 
II.—Cordate, crenulated on margin, upper 
surface marbled .... 
III.—Angular, toothed, broadly marbled 
on upper surface, leaves rising 
with the flowers. 
IY.—Angular, lobed, marbled, leaves suc¬ 
ceeding the flowers

hedercefolium. 
Einally, as a less reliable guide, we have fragrance, but here 
there does not seem to be any unchangeable or distinct habit. 
Europceum , vernum , and persicum are said to be always fragrant. 
So they are in nature, but in cultivation this very desirable quality 
is in great measure lost, and in the large otherwise improved persi- 
cums entirely so. C. Coum , ibericum , and hedercefolium are 
always scentless, except the two forms of the last— Africanum 
and Grcecum —which are sometimes fragrant. 
We will now proceed to a closer examination of the six species 
I have named. 
I.— C. Coum . 
A native of Italy and Germany. 
Blooms from January to March. Colour bright rosy red, with a 
white band more or less distinct round the corona. Leaves always 
round, dark green on the upper surface, decided purple on the
