Limonium melitense Brullo (1988: 13) View in CoL ( Fig. 4 View FIGURE 4 )

Typus : MALTA: Malta, Golden Bay, 28 September 1985, S. Brullo s.n. (Holotype CAT 012554!, isotype CAT 012554! hoc loco, B 100294997! designated by Brullo (1988:13),, G-293596/1! hoc loco) .

= Statice cosyrensis Gussone (1832: 99) var. melitensis Sommier & Caruana Gatto (1915: 213) .

Statice cosyrense auct. fl. melit., non Gussone (1932).

Plant perennial, glabrous, with caudices dense, branched, 0.5–4 cm long. Leaves green, rigid, laxly inserted on the caudices, oblanceolate, 1-nerved, 10–40 mm long, 3–8 mm wide, flat, rounded or retuse at the apex, usually withered at anthesis. Stem several, rigid, erect, 8–45 cm tall, densely branched from the base, paniculate, with numerous much branched sterile branches.Articles slightly arched, 3–20 (40) mm long, with deepned glands, forming branching angles of 15–45°. Inflorescence paniculate, with fertile branches localized at the top of the stem. Spikes 10–45 (70) mm long, straight to slightly divaricate, with spikelets remotely arranged. Spikelets 7–8 mm long, 3–4 per cm, 2–3 (4) flowered. Outer bract 1.5–2 mm long, ovate-triangular, acute, coriaceous in the central part, forming an apiculum 0.6–0.9 mm long, membranous at margin. Middle bract membranous, rounded, 1.5–2.2 mm long. Inner bract (4.5)4.8–5(5.5) mm long, 2.3–2.7 mm wide, elliptical, rounded, with outer hyaline margin and pale brown inner margin, central part herbaceous, with an apiculum 1–1.4 mm long, not reaching the apex. Calyx 5–6 mm long, sparsely hairy in the tube, 2.5–3 mm protruding from the inner bract, with tube 1.5–1.8 mm long and limb 3.5–4 mm long, with midribs ending in the middle of the lobes, which are semi-elliptical, 0.5–0.7 mm long.

Etymology: — The epithet refers to “Melita”, Latin name of Malta.

Phenology: — Limonium melitense flowers from June to October and produces seeds from August to November.

Distribution and ecology: — Similarly to Limonium zeraphae and L. lanfrancoi , also L. melitense is a species exclusive of the Maltese Archipelago, where it occurs in all the islands, mainly in the rocky coast ( Fig. 7 View FIGURE 7 ). It is a chamaephyte, showing an erect and densely branched habit and can be considered an edaphic vicariant of L. zeraphae , localizing mainly on Globigerina limestones and marly limestones. Sometimes, it occurs also on compact limestones, but limitedly to shade stands, showing clearly more mesic requirements than the previous species. The plant community physiognomically characterized by this species was described by Brullo et al. (2020) as Limonietum melitensis , association always belonging to Crucianellion rupestris . In fact, the species of this alliance are here well represented, such as Crucianella rupestris , Cichorium spinosum and Daucus rupestris . As concerns the distribution of this association, it is widespread mainly in the northern and north-west coasts of Malta, as well as in Gozo and Comino.

Conservation status:— As already highlighted for Limonium zeraphae , L. melitensis has also undergone a drastic reduction of its range due to the anthropic impact on the coasts. Therefore, the progressive and constant regression of its populations with a much lower number of individuals than in the past, L. melitensis should be classified, according to IUCN protocol ( IUCN 2023), as “vulnerable” VU A2.
