|Scientific Name:||Scilla morrisii Meikle|
|Taxonomic Source(s):||WCSP. 2015. World Checklist of Selected Plant Families. Available at: http://apps.kew.org/wcsp/.|
|Taxonomic Notes:||C-band karyotyping and DNA content determinations by Greilhuber and Speta (1989) indicate that Scilla morrisii and Scilla cilicica are sibling species and that all Cypriot provenances actually belong to one endemic species, by priority Scilla morrisii, while Scilla cilicica is restricted to southern Anatolia. Some variability exists with regard to flower colour and possibly timing of leaf expansion of Scilla morrisii.
Greilhuber and Speta (1989) noted that the species Scilla morrisii may include populations of the plant identified as Scilla cilicica which occurs generally in more rocky habitats. This would alter the distribution and population data on the species, but further research is needed in order to confirm.
Andreou et al. (2015) found that two previously reported subpopulations of the plant in the Agios Neophytos area consist of hybrid plants of S. morrisii and S. cilicica Siehe, and are disregarded here, with further research required to determine if unhybridised individuals of S. morrisii exist at these two subpopulations.
Taking into consideration the above new findings and results, the distribution, range and total population of Scilla morrisii (sensu Greilhuber and Speta 1989, Speta 2011) maybe considerably larger; therefore a closer examination of these parameters may reveal that the IUCN category of Scilla morrisii (classified as Endangered in the Red Data Book of the Flora of Cyprus) should be downgraded. This issue should be discussed and resolved during the next Biogeographic seminar in order to arrange for the next monitoring and reporting of this species.

The taxonomy of the species is controversial (Hand et al. 2011); Meikle (1985) described two species of the Scilla siberica alliance; 1) Scilla cilicica, which occurs in Cyprus in crevices of limestone rocks (30-1,000 m altitude) along the Pentadactylos range and on the Akamas Peninsula and 2) Scilla morrisii, a very rare micro-endemic confined only to the vicinity of Chrysorrogiatissa monastery in moist shaded places mainly under Quercus infectoria subsp veneris, at an altitude of about 800 m. Greilhuber and Speta (1989) indicate that the two taxa are sibling species and that all Cypriot provenances actually belong to one endemic species, by priority Scilla morrisii, while Scilla cilicica is restricted to southern Anatolia. Some variability exists with regard to flower colour and possibly timing of leaf expansion of Scilla morrisii.
Furthermore, Speta (2011) suggests that the description of Scilla (Othocallis) morrisii by Meikle (specimen 573, 1975 in Kew) was based on untypically coloured plants which were modified by a fungus (Uromyces scillarum); this is mainly the reason for accepting two separate species for the western part of the island. Also, it is suggested that plants from Pentadaktylos range are slightly different karyologically (Othocallis morrisii var. veneris).
Taking into consideration the above new findings and results, the distribution, range and total population of Scilla morrisii (sensu Greilhuber and Speta 1989 and Speta 2011) are considerably larger. Despite that, the species is assessed as EN (B1ab(ii,iii)+2ab(ii,iii)) due to an observed decline in population and AOO in one of its locations.
|Previously published Red List assessments:|
|Range Description:||This species is endemic to the western part of the island of Cyprus, growing between 25 and 1,000 m asl.|

|Population:||The population size was reported to be less than 600 individuals (Montmollin and Strahm 2005). It was later estimated to be between 1,800 and 2,100 individuals (Commission of the European Communities 2009), and at about 1,000 individuals according to Tsintides et al. (2007).|
Excluding hybrid subpopulations at the ‘Mavrokolympos’ Natura 2000 site, Andreou et al. (2015) considered the population to be stable at around 1,000 mature individuals, reporting the following numbers of mature individuals during a three-year monitoring project; 955 (2006), 1,669 (2007), and 1,044 (2008). Some colonies have been lost as the result of vineyard cultivation in 2007, although population size at other sub-populations increased over the period 2006-2007 (Andreou et al. 2015). The species populations are considered to be severely fragmented.
|Current Population Trend:||Stable|
|Habitat and Ecology:||This is a perennial plant which overwinters as a bulb, in which nutrients are stored for the next spring. This species occurs mainly in north facing sides of slopes and sometimes in streams and under Quercus infectoria subsp. veneris or Pistacia terebinthus. It prefers moist, shaded crevices and banks.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||The plant is not known to be utilized. All species in the Scilla genus are known for their toxic properties, which may cause serious digestive disorders.|
|Major Threat(s):||The construction of roads at one site (‘Vouni Panagias’) and the low to moderate frequency of human induced fires were identified as the direct threats to the plant (Andreou et al. 2015). Competition from synanthropic species, such as Allium neapolitanum Cyr., Silene vulgaris (Moench) Garcke, Muscari comosum (L.) Mill., Hordeum bulbosum L., Trifolium clypeatum L., Opopanax hispidus (Friv.) Griseb., Veronica cymbalaria Bodard subsp. panormitana (Tineo ex Guss.) O.Bolòs & Vigo, Stellaria media (L.) Vill. subsp. media, Octhodium aegyptiacum (L.) DC., Galium aparine L., was evidenced at one sub-population (Andreou et al. 2015). Ecosystem conversion to cultivated areas and inbreeding due to the small and isolated subpopulations (Lienert 2004) were recorded, too. Kadis and Christodoulou (2006) also reported logging and forest clearance, and impacts from predators as threats.The above threats have been identified for Scilla morrisii sensu Meikle (1985) at Vouni Panagias.|
|Conservation Actions:||All known individuals are within the Parco delle Madonie Regional Natural Park, with some individuals also within the Monte Quacella, Monte dei Cervi, Pizzo Carbonara, Monte Ferro, Pizzo Otiero Site of Community Importance (Habitats Directive). The survival of this species depends on the conservation of the remaining oak forests and Pistacia trees. These have been considerably reduced by logging for timber, road construction and expansion of farmland. Large old oak trees have become rare and scattered where there used to be a closed forest cover. While the overall number of individuals do not seem to be declining, some sites within known sub-populations have been lost as a result of habitat conversion (Andreou et al. 2015), and the extent of its habitat is decreasing due to road construction, increased agricultural land use, and other threats (Montmollin and Strahm 2005).|
