Convolvulus georgicus Sa’ad, Meded. Bot. Mus. Herb. Rijks Univ. Utrecht 281: 180. 1967. ( Sa’ad 1967: 180). Type. "Georgia, Mount Swant", Hohenacker s.n. (holotype W!).

Distinguishing features.

Sepals pubescent with appressed hairs, the margins glabrous.

Distribution.

Italy: Liguria (Bicknell 3346, Joad 1882).

Notes.

The type of Convolvulus georgicus is a small scrap with a single flower and the appearance of Convolvulus sabatius . Examination of the sepals confirms not only that they are the same shape as those of subsp. sabatius but also have its distinct indumentum with a band of appressed hairs along the centre leaving the margin glabrous. The collection might have been of a cultivated plant but was more probably mislabelled in the herbarium. Convolvulus sabatius should not be included in the list of species occurring in Georgia.
