158. Convolvulus argyrothamnos Greuter, Bauhinia 3: 251. 1967. (Greuter 1967: 251).

Type.

GREECE, Crete, Ierápetra. Greuter 7802 (holotype Hb. Greuter (B or PAL?); isotypes E00288017!, G, LD, W!).

Distinguishing features.

Undershrub clearly related to Convolvulus oleifolius and distinguished by its unusual habit. It is a pendulous plant, strongly acrotonous in its branching with the leaves in fasciculate bunches. No floral differences from Convolvulus oleifolius are known.

Description.

Endemic to Crete.

Notes.

It is impossible to confirm whether this is a distinct relict species or some peculiar adaptation of Convolvulus oleifolius to the cliff habitat. Its population is apparently restricted to a small number of plants on one or two limestone cliffs.
