Description: —Plant perennial, glabrous, forming a sub-shrub 10–40 cm tall, with few to several ascending to erect stems and a robust tap-root. Caudices 1–11 cm long, densely branched, more or less densely spirally leafy in the upper half. Leaves coriaceous, grey-glaucous, rigid, tuberculate with many crateriform glands or verrucate with crescent-shapes glands, 10–60 mm long and 1.5–5.0 mm broad, narrowly oblanceolate to narrowly spathulate, apex obtuse to acute, mucronulate, v-shaped in cross-section, with one central nerve, gradually tapering into the petiole. Stems 10–35 cm long, grey-glaucous, tuberculate with many crateriform glands, straight to slightly flexuous, branching begins above the lower quarter, sometimes proliferous. Inflorescence broadly obtrullate to obtriangular in outline. Sterile branches several per stem, 5–55 mm long, straight, unbranched. Fertile branches 1–14 cm long, sometimes slightly articulate, often tuberculate with many crateriform glands, straight to slightly arched, directed obliquely upwards, forming branching angles of 35°–75°, branched or unbranched. Spikes 10–120 mm long, straight to slightly arched, erect to directed obliquely upwards; axis of spike with many crateriform glands. Spikelets 8.5–10 mm long, composed of 2–6 flowers, very remotely arranged with 1–6 per 2 cm. Outer bract 2.7–3.5 mm long and 2.3–3.0 mm broad, more or less narrowly triangular-ovate, obtuse; bract margin broadly membranous; central part slightly fleshy, sometimes only on the base, acuminate. Middle bract membranous, 2.6–3.5 mm long and 1.8–2.5 mm broad, oblong-elliptic, rounded. Inner bract 7.4–8.2 mm long and 3.8–5.1 mm broad, oblong-obovate, rounded; bract margin broadly membranous; central part fleshy, 5.6–6.8 mm long and 2.6–3.8 mm broad, oblong, acuminate, forming a narrowly triangular tip, 0.9–1.2 mm long, not reaching the upper

BRULLO & ERBEN

Chromosome number: —2n = 43 (Erben Li–1574, Li–1709, unpubl.).

Distribution: —This species is very common on Karpathos and rare on Kasos ( Fig. 88A ).

Habitat: — L. amopicum is widespread along the rocky coast, where it grows on various substrates.

Etymology: —The species is named after Amopi, a locality in the southeast coast of Karpathos.

Taxonomic remarks: — L. amopicum belongs to a group of taxa distributed in the southeastern Aegean area including L. carpathum , L. monolithicum and L. sitiacum , all of which are characterized by having glaucous stems and leaves, only a few (or none) sterile branches, and quite long spikes with remotely arranged spikelets. It differs from all other taxa of L. carpathum group with except of L. sitiacum by having longer inner bracts and from L. sitiacum by having smaller leaves and longer calyces.
