Limestone / beachrock riff extremely rugged, close to the water line,  14 July 1990, Mayer 0654B( holotypeM!, isotype Herb. A. Mayer).   Description:—Plant perennial, glabrous, forming a sub-shrub 15–55 cmtall, with few erect stems and a robust tap-root. Caudices 20–80 mmlong, densely branched and densely spirally leafy with withered leaves; living leaves in rosettes at apices. Leaves fleshy, glaucous, flat, smooth, 15–35 mmlong and 4–10 mmbroad, spathulate to oblanceolate, apex obtuse to round, retuse, slightly mucronate, with one central nerve, gradually tapering into the petiole. Stems glaucous, 12–45 cmlong, slightly flexuous, rugose, sometimes verrucate, branching begins above the base of the stems, sometimes proliferating in axils. Inflorescence trullate or obtrullate in outline. Sterile branches absent or only 1–2 per stem, 0.5–5 cmlong, straight, unbranched. Fertile branches 1–11 cmlong, slightly arched to straight, directed obliquely upwards, forming branching angles of 35°–60°, normally unbranched. Spikes 20–80 mmlong, arched, inserted obliquely or spreading. Spikelets 8.5–9.0 mm long, composed of 1–3 flowers, very remotely arranged with 1–4 per 2 cm. Outer bract 2.7–3.2 mmlong and 1.8–2.1 mmbroad, triangular–elliptic, acute to obtuse; bract margin broadly membranous; central part slightly fleshy, sometimes only at the base, acuminate. Middle bract membranous, 3.0– 3.3 mmlong and 1.8–2.2 mmbroad, oblong to obovate-elliptic,  70• Phytotaxa240 (1) © 2016 Magnolia Press BRULLO & ERBEN rounded. Inner bract 7.8–8.3 mmlong and 3.7–4.2 mmbroad, obovate to elliptic, obtuse; bract margin broadly membranous; central part slightly fleshy, 5.2–6.1 mmlong and 2.1–2.6 mmbroad, oblong, acuminate, forming a narrowly triangular tip, 1.2–1.8 mmlong, not reaching the upper margin. Calyx 6.2–7.0 mm long, exceeding the inner bract by 0.5–1.0 mm; calyx tube sparsely shortly to long hairy, with 5 ribs ending near the upper margin of lobes; calyx lobes ca. 1.0 × 1.2 mm, semi-elliptic to triangular-ovate. Corolla sky-blue.   FIGURE 24.  Limonium monolithicumErben & Brullo. A )Habit; B)Spikelet; C)Outer bract; D)Middle bract; E)Inner bract; F)Calyx; G)Calyx lobes; H)Leaves. (Drawn from “Rodi, Akr.

It differs from  L. sitiacumby having more remotely arranged spikelets and shorter inner bracts.  L. calliopsiumdiffers from  L. oligotrichumand  L. amopicumby having broader, smooth leaves, from  L. vanandenseand  L. samiumby having longer inner bracts and smooth leaves and from  L. monolithicumby having smooth leaves and shorter calyces.  Specimens examined:—  GREECE.  Crete: Creta, in rupestribus maritimis ultra Gerani, distr. Rethymniotika,  11 July 1899, Baldacci 246(M, W, WU); Creta, Gerani,  26 August 1996,  Brullo& Guarinos.n.(CAT, Herb.
