VIII. — C. NEAPOLITANUM. 



(Has borne the specific names of subliastatum, autumnale, 

 pyrenaicum, eurOpaum, ficariifolium, and hedercefolium, 

 under which last name it is still most generally known in 

 nurseries and gardens.) 



Blooms, September and November ; all shades between deep 

 crimson and pure white, the two extremes being the least 

 common ; very distinct ear-like protruberances at the base of 

 each petal. 



Scent, none. 



Leaves, after flowers ; oval heart-shaped, or shield-shaped, 

 but very irregular and variable ; distinct angular projections 

 from the margin, with often a very small toothing all round the 

 edge as well ; seldom dark green, or free from marbling, but 

 generally with most beautiful bright silvery bands and markings ; 

 the leaves die down in early summer. 



Tuber, very large, rough, dark brown, scaly when old ; some- 

 times reported as much as a foot in diameter ; roots proceeding 

 from all parts of the tuber, but chiefly from the rim on the 

 upper surface. 



Habitat, Central and Southern Europe ; very abundant about 

 Corfu and in the Ionian Islands. 



Perfectly hardy, and the most beautiful of all. 



C. linearifolium (De Candolle), Bot. Beg. xxiv. 49 ; Garden, 

 August 19, 1875, is a monstrous variety of this species. 



IX. — C. AFEICANUM. 



(Has borne the specific names of macrophyllum, neapolitamtm, 

 robustum, and algeriense.) 



Blooms, September and October. 



Leaves, very broad, with foot-stalks sometimes eight to twelve 

 inches high, and not fully developed till December. 



In all other respects similar to a very large coarse-growing 

 neapolitanum, to which it is a very close relation. 



Habitat, the mountains of Algiers. 



There is said to be a variety of this which has the under- 

 surface of the leaves green, and another with the leaves lilac 

 beneath, and the flowers fragrant.
