notes Slo.: šesterokotna homulica - syn.: Sedum boloniense Loisel., Sedum tschernokolevii Stef., 'Sedum mite' sec. auct., Sedum forsterianum Rchb., Sedum acre subs. sexangulare (L.) O.Schwartz - Habitat: Rocky sea shore; inclined terrain, southeast aspect, a few meters from the sea; full sun, hot, dry, open terrain, exposed to direct rain; elevation 3-6 m (10 -20 feet); average precipitations ~ 1.000 mm/year, average temperature 13-14 deg C, Sub-Mediterranean phytogeographical region. - Substratum: soil in rocks crevices. - Comment (pertains to pictures in the Flickr album Sedum sexangulare): Sedum sexangulare is a succulent species with mainly European native distribution. It grows now introduced also in UK, USA and Canada. In Slovenia 15 taxa of genus Sedum are described and in Croatia about 30. Most of them are variable plants and their taxonomy, particularly in Sedum acre agg. group, is not yet settled completely (Ref.4). - Sedum sexangulare can be recognized by its typical arrangement of leaves, which, when looked at from above, form a six leg star (sexangulare!) (Fig. 10). This arrangement is most distinctive on sterile, not too old and not too young shots. When shots are very young they have very compressed leaves of different size and this arrangement is not so apparent. When they are old and having inflorescence their stem lengthens during anthese very much and this arrangement is again not so obvious and distinctive. There are other traits typical for this species: cross-section of the leaves is almost circular (leaves are cylindrical in shape), at the top they are blunt, and at the point where they are attached to the stem they have an inconspicuous 'spur' or 'dent'. Petals are acute. - Sedum sexangulare usually grows in quite large mats, sometime one meter or more wide. On my pictures the plants thrive in an extremely nutrition poor, rocky environment, in almost barren rock next to the sea shore. Hence they are mostly 'individuals'. The plant is widely used in gardening as an excellent ground cover. - Ref.: - (1) Personal communication with Mrs. Ljiljana Borovečki-Voska, Zagreb, Croatia. (2) D. Aeschimann, K. Lauber, D.M.
