A very pretty and little known species of Convolvulus, de- 
tected in the interior of northern Africa, near Constantine, com- 
municated to M. Boissier by M. Séjourné, and published in a note 
in the botany of M. Boissier’s interesting ‘ Voyage en Espagne.’ 
It is distinguished from C. Siculus and C. pentapetaloides by its 
woody and perennial root, its leaves never cordate, shortly pe- 
tiolate, and by the size of its flowers: from C. tricolor by some 
of the same characters, the leaves not attenuated upon the pe- 
tioles, its many-flowered peduncles, the length of the bractez 
and of the sepals. The C. suffrutricosus, Desf., and C. Canta- 
brica, L.., which are also perennial, have the leaves lanceolate or 
linear, the peduncles much elongated, etc. 
Our flowering specimen was received from the garden of Mr. 
William Thompson, of Ipswich, where it blossomed in the open 
air, in October 1860. 
Descr. foot perennial, sublignose, branched, about the 
thickness of a goose-quill, This throws out several slender, 
almost filiform, prostrate, flexuose stems, which are simple,
