location
Slatinica bay, east shore of the island Olib, Kvarner bay (Adriatic Sea, Croatia)notes Slo.: ostro ločje, ostri loček - Habitat: a few meters from sea shore, partly salt march; sandy calcareous ground; full sun; elevation 1 m (3 feet); average precipitations ~ 900 mm/year, average temperature 12-14 deg C, (sub)Mediterranean phytogeographical region. Substratum: soil among sea shore pebbles. Comment: Juncus acutus is a tall (up to 1.8 m), robust plant quite easy to recognize in spite of the fact that genus Juncus includes many, many species. It is a warmth loving Mediterranean plant growing in all countries around Mediterranean Sea (Ref.2). In Slovenia it is quite rare and restricted exclusively to Adriatic Sea shore (Ref.: 5). The plant can be recognized by its notable size, densely tufted habit and firm, basal, sharply pointed and longer than flower stems leaves. Reddish-brown flowers are interesting when observed from close (hand lens). The pictures show the plant in seeds (capsules). A quite remarkable member of Juncus genus! Ref.: (1) A.
