CONVOLVULUS. 
‘the lower regions of Eastern Spain and Central Spain. C. sericeus 
is a specially silky and silvered variety of this green hairy-leaved 
species. 
C. libanoticus makes a low tuft of hoary grey, from which emerge 
flopping stems set with attenuated oblong leaves, and ending in large 
flesh-pink cups. (From Hermon and from Lebanon, in the dry alps 
above the Cedars.) 
C. lineatus fills the hard clayey stony places, limy barrens, and dry 
screes throughout the Alps of Spain, and so, through all the Levant, 
away into the Altai. It makes a beautiful close mass of stalks, from 
3 inches up to a foot, beset with oval foliage clad in a well-ironed pile 
of silver hair. The clustered flowers are white. Almost exactly 
similar to this is C. holosericeus, of the same habit and silvery glamour, 
but found in Asia Minor. 
C. mauritanicus is a most useful trailer, especially in mild climates, 
where it runs freely about, throwing far over the rocks its long slender 
arms, set with dark kidney-shaped hairy foliage, and generous with 
large beautiful flowers of clear lilac-blue. A good cascade of this, in 
a sunny exposure and climate, is a thing of beauty all the summer 
through. Various improved forms are sometimes offered, of which 
C. m. atrocoeruleus is the best. 
C. nitidus is one of the loveliest of all. Small mutilated fragments 
are now falling into our hands, and being sedulously nursed as they 
deserve. This treasure forms enormous, wide and perfectly tight 
masses in the dolomitic fissures, dry stony places, and barrens in 
the sub-alpine and alpine regions of the Sierra Nevada, between 
6000 and 7000 feet (as on the summits of Dornajo, Trevenque, and ~ 
Aquilones), but is nowhere common; the cushion is built of ovate, 
blunt, folded little leaves, marked with nerves, and gleaming brilliantly 
with a plating of the finest silver sheen, soft and silky. Upon this 
spring stems so short as to be no stems at all, each carrying from one 
to four large and ravishing cups of rosy white, seeming to be scattered 
upon the surface of the mat; and in their general effect giving the 
casual eye a notion that a clearly-blushing Ovxalis enneaphylla (such 
as eye has never seen) must have stuck its blossoms over a dense high- 
alpine mat of Potentilla nitida. (It seems an awfully shy flowerer.) 
C. oleaefolius is a more upstanding species, after the style of C. 
cneorum, and C. lineatus. 
C. parnassicus=C. cochlearis, q.v. 
C. radicans may possibly prove a variety of C. cantabricus. In 
the hard dry clay of the fields above Trikala, at some 5000 feet up on 
Kylléné, it builds dense tufts rather like those of C. cochlearis, but
