CISTACE^ 89 



diameter, solitary or in twos or threes. Leaves bright green on both 

 sides and generally broader than those of H. vulgare. 

 Dry Alpine pastures up to 7400 feet. June to August. 



This large-flowered variety is particularly fine at Mont Cenis, in 

 Savoy and the Ligurian Alps. 



Messrs. Schinz and Keller in their Flore de la Suisse give two 

 sub-species of H. vulgare, viz. H. barbatum Lam. and H. nummul- 

 arium Miller. The leaves of the former are green and glabrescent, 

 and those of the latter white-tomentose beneath. 



In the Ligurian and Maritime Alps there are two pretty rose- 

 coloured plants which Mr. Bicknell ^ describes under H. vulgare : 



Var. roseum Bumat=fl'. roseum Bert. 



Plant gre5dsh by reason of the short hairs covering the stems, 

 leaves, and pedicels. Flowers usually pink, rarely crimson or nearly 

 white. Very common on dry banks in the littoral region. 



Var. semiglabrum Bumat=ff. semiglabrum Ba.d.:= H. J acquini Ard. 



Leaves light green, narrow, and shining, the upper ones as well 

 as the pedicels glabrous, or nearly so. Flowers pink. Not common 

 in the littoral region. Val Nervia, etc. It is very common about 

 Pigna in the Ligurian Mountains. 



Various other species grow in Spain and the Mediterranean 

 district, among the foot-hills and lower mountains, several of which 

 are worth cultivating. 



The Rock Roses are of the easiest culture in almost any light, 

 rather poor soil fully exposed to the sun ; and they strike 

 readily from cuttings. If cut back after flowering they tend to grow 

 more compact. The hybrids are very numerous and many of them 

 extremely beautiful, being in all shades of yellow, salmon-pink, 

 rose, and crimson. Few plants are of greater value for the rockery, 

 for in addition to their beauty they grow very quickly. The 

 nomenclature, however, of this genus seems somewhat confused. 

 The tendency to hybridise may partly account for this. 



FuMANA Spach. 



A genus closely allied to the last. The flowers are usually smaller 

 and the habit shrubbier. The sepals are always 5, the 2 exterior 

 being smaller ; and the capsule is 3-celled. 



Fumana procumbens Gren. et Godr. 



A recumbent small undershrub, 3-10 inches high, with woody 

 base and branching stems. Leaves linear, sub-obtuse, mucronate, 

 green, not stipuled, rough-edged. Flowers solitary, yellow, 1-4 on 

 the upper part of the branches. Pedicels thick, deflexed, shorter
