CONVOLVULUS éazartvs, Viv. 
Natural Order ConvoLvuLACcE®. 
Gen. Cuar.—See description of Plate XXX. Part IT. 
Spec. Cuar.— Flowers of a fine mauve colour, with small yellow centre, 
solitary or in pairs, crowded together towards the ends of the branches; 
two or three expanded at the same time on the same branch ; peduncles 
and pedicels covered with adpressed hairs (recurved when fruiting, 
Rehb.*) ; bracts linear or linear-lanceolate, distant from the flower. 
Sepals oblong-lanceolate, contracted under the apex, covered with small, 
white, adpressed hairs. Anthers white. Disk bright yellow, forming a 
prominent, cup-shaped ring round the ovary. (Capsule globose, nearly 
equalling calyx, 2-celled and 2-valved, Bert.t). Zeaves thick in texture, 
opaque, set closely together, oblong-ovate, truncate or subcordate at 
the base, obtuse or emarginate, lowest leaves obovate, covered with mi- 
nute, adpressed hairs; petioles about one-third of limb. Branches de- 
cumbent, not rooting or twining, densely covered when young with 
minute, adpressed hairs, forming a dense mat round the central knotted 
perennial stem.

Hasirat.—Capo di Noli, eastward of Finale, where I gathered it on 
April 20, 1868. 
Remarxs.—This very beautiful Convolvulus is only known to grow 
on this one promontory of Noli, the Vada Sabatia of the Romans, in 
the whole world. It is, therefore, necessary to consider its affinities 
with other species carefully. Undoubtedly its nearest ally is Convol- 
vulus mauritanicus, Boiss.,f a plant found near Constantine, in Algiers, 
and now largely grown in English gardens. Perhaps Convolvulus mauri- 
tanicus, Boiss., should be treated as a variety of Convolvulus sabatius, 
Viy., but I find from the description and drawing given by Boissier that 
it differs in the following characters:—Convolvulus mauritanicus, Boiss., 
has the flowers and leaves much scattered, and leaves, calyces, and 
younger parts of the stem covered with long, spreading hairs, the leaves 
are of a thin texture, the anthers also are represented as being yellow, 
and the corolla striped with pink along the folds. But we must re- 
member that Convolvulus sabatius, Viv., only grows on this one great
