“…Anthropogenic activities in the last century may have "carried" it further south into the major urban areas oflsrael. Alternatively, as has been claimed previously for two Crocus species (Feinbrun and Shmida, 1977), the remarkable gaps in the distribution of S. vulgaris var. vulgaris, from the Upper Golan to Mt.…”

ABSTRACfCommon Groundsel (Senecio vulgaris L. var. vulgaris (2n = 40)) is widespread in the northern hemisphere. In Israel, judging from a herbarium survey, records taken from the Israel Plant Information Center (ROTEM), and field studies, it has a restricted and widely disjunct pattern of geographical distribution, and, thus, is another example of the comparatively large group of weeds in Israel which are extremely stenochorous. The remarkable gaps in its distribution, from the Upper Golan to Mt. Carmel and to the Jerusalem area, are considered primarily to be the result of paleoclimatic changes, whereas its occurrence outside these centers of distribution is probably related to long-distance dispersal events. Natural hybridization of S. vulgaris with its closest ally, S. vernalis Waldst. et Kit. (2n = 20), results in formation of their shortly ligulate and highly sterile hybrid, S. x helwingii Beger ex Hegi (2n = 30), which is reported for the first time from the Israel area. Hybrid frequencies of 8. 7 and 9.8%, respectively, were found in the two mixed populations examined in the Upper Golan. These are higher than previously reported for two localities of hybridization in Central Europe ( 1.1 and 1.5% ), and probably indicate a closer genetic affinity of S. vulgaris var. vulgaris to S. vernalis from Israel than to S. vernalis from Central Europe. It is likely that reports of radiate variants of S. vulgaris var. vulgaris from the Israel area, none of which could be confirmed, refer to S. x helwingii.

A phylogenetic analysis of the genus Colchicum (including Bulbocodium and Merendera) is presented. The phylogeny includes all but four of the 100 species and all subspecies currently recognized in the genus, two insufficiently known species (C. mirzoevae, C. stenopetalum), and one cultivated specimen (C. laetum hort.) probably of hybrid origin. The analysis is based on 292 parsimony-informative characters derived from nucleotide sequences from six plastid regions (trnL intron, trnL-trnF IGS, trnY-trnD IGS, trnH-psbA IGS, atpB-rbcL IGS, rps16 intron) and 33 morphological, life history, and chromosomal characters. The genus Colchicum is strongly supported as monophyletic. The morphological data are considerably more homoplasious than the molecular characters, but provide added resolution to the trees derived from a combined analysis. The phylogenetic hypothesis is largely in conflict with the subgenera and sections recognized by Stefanov, and agrees better with some of the informal species groups defined by Persson in earlier publications. Additional data will be needed to resolve all relationships.

“…The hexaploid plants flowered during the second half of April and the first two weeks of May Using the key to the genera of the Scilleae and Chlorogaleae by BAKER (1872), the author arrived at the conclusion that the triploid plants belong to Ornithogalum umbellatum L., the hexaploids to O. divergens Boreau. FEINBRUN (1941) is of the opinion that O. divergens is a Mediterranean species, whereas O. umbellatum is distributed throughout Europe with the exception of some areas in northern Scandinavia and the East of Russia. O. divergens Bor.…”

SUMMARYThe bulbs form leaf-bearing bulbils. Very soon the bulbils and bulbs separate from each other but remain in very close proximity to each other. The leaves are linear, light green or green, 13-15 cm long and 2.5-3.5 mm wide. A conspicuous white stripe is visible on the upper side of the leaves. The inflorescence is narrow, few-flowered (3-5 flowers) and visible from the end of April onwards.The pedicels are ascending, the length of the lowermost pedicel being 3-3.5 cm, the corresponding membranaceous bract 2.5-3 cm. The outer tepals are 15 mm long and 5 mm wide, the filaments are 5-6 mm long. The fruits are capsular, blunt at the top, and provided with 6 prominent longitudinal ribs. The triploids flowered in 1971 during the second half of May (see fig. I).
