A 1984 [192,517,1195,1221] Magnoliopsida Plumbaginaceae Limonium Plantae Caryophyllales 84 Tracheophyta species ithacense    Type:― GREECE.  Ionian Islands:Ins. Ithaki: in saxosis calcareis maritimis, prope pagum Stavros,  Artelari237( holotypeUPA).   Description:—Plant perennial, glabrous, forming a sub-shrub 10–25 cmtall, with ascending to erect stems and a robust tap-root. Caudices 1–9 cmlong, branched, living leaves in rosettes at apices. Leaves fleshy, rigid, 5–32 mmlong and 1.5–7.0 mm broad, narrowly spathulate to narrowly oblanceolate, apex obtuse to rotund, sometimes slightly emarginate, margin more or less revolute, with one central nerve, gradually tapering into the petiole. Stems slender, rugose, 4–20 cmlong, slightly flexuous to straight, branching begins near the base. Inflorescence corymbose. Sterile branches few to several, confined to the lower half of the stems, slender, 0.5–3.0 cm long, straight to arched, mostly unbranched. Fertile branches confined to the upper half of the stems, slender, 1–5 cmlong, slightly arched to straight, forming branching angles of 35°– 55°, branched. Spikes 5–30 mmlong, straight to arched, erect to inserted obliquely upwards. Spikelets slender, 6.0– 6.4 mmlong, composed of 1 (–2) flowers, remotely arranged with 2–4 per cm. Outer bract 0.9–1.2 mmlong and 1.4–1.7 mmbroad, broadly triangular-ovate, acute to obtuse; bract margin narrowly membranous; central part slightly fleshy, acuminate. Middle bract membranous, 1.4–1.9 mmlong and 1.4–1.6 mmbroad, elliptic, rounded. Inner bract 3.5–4.1 mmlong and 2.8–3.2 mmbroad, elliptic, rounded to obtuse; bract margin broadly membranous; central part fleshy, 2.6–3.1 mmlong and 1.7–2.0 mm broad, oblong, acuminate, forming a narrowly triangular tip, 0.6–0.8 mmlong, reaching nearly the upper margin. Calyx 4.7–5.3 mmlong, exceeding the inner bract by 2.1–2.3 mm; calyx tube more or less sparsely shortly hairy, with 5 ribs ending above the base of lobes; calyx lobes ca. 0.8 × 1.0 mm, semi-elliptic. Corolla violet.  Chromosome number:—2n = 18 (Artelari 1984a, b).   Distribution:—Occurring on the Ionian Islandsof Ithaki and Kefalonia, where it is very rare ( Fig. 89F).  Habitat:—Calcareous rocky coast.   LIMONIUM(PLUMBAGINACEAE)  Phytotaxa240 (1) © 2016 Magnolia Press • 85 86• Phytotaxa240 (1) © 2016 Magnolia Press   FIGURE 33.  Limonium ithacenseArtelari. A )Habit; B)Spikelet; C)Outer bract; D)Middle bract; E)Inner bract; F)Calyx; G)Calyx lobes; H)Leaves.
