    Notes: Abstract Noaea griffithii, which hitherto was known from the type collection only, is transferred toSalsola by reason of its horizontal embryo and other fruit characters. The description is completed; ecological, phytocoenological and distributional data are given. The species is a common endemic psammophyte of SE Iran, S Afghanistan and adjacent Pakistan Baluchistan.

    Notes: Abstract 88 species and 20 subspecies ofCarex, altogether 94 taxa, occur in the area ofRechinger's Flora Iranica. Of these, 48 taxa, have an Euro-Siberian, 11 an Irano-Turanian and 35 a Central Asiatic distribution, the last including five species with connections to E. and tropical SE. Asia. The Saharo-Sindian element is missing. Endemic taxa are found in all groups. Eight taxa, endemic to the NW. Himalayas occur in the E. part of the area. The Euro-Siberian taxa are concentrated in the NW. of the area, but have connections to the east; similarly, Central-Asiatic taxa are concentrated in E. Afghanistan and N. Pakistan, but have connections to the west. Some Euro-Siberian taxa are widely distributed in the area, but avoid the most arid regions. The Irano-Turanian taxa are few and extend from Egypt through the area of Flora Iranica to Kazakhstan SSR and Central China.

    Notes: Abstract On the basis of new floristic works a distribution map of the genusCousinia is given and discussed. The generic distribution area ofCousinia is nearly identical with the Irano-Turanian Region, but most of the 662 species are concentrated on the Iranian and Turkestanian mountain regions. Here, both in the eastern and in the western parts of the distribution area, four centres of diversity with high numbers of—mostly endemic—species are found: The western Tienshan (61 species), Pamiro-Alaj (169), NE-Afghanistan (80), NW-Afghanistan (44); Kopetdagh (66 in Iran, 33 in Turkmenia), Elburz (66), the northern part of Zagros (44), Azerbaijan (36). The outlines of the generic area are formed by genetic-historical and by climatic factors. The distribution patterns ofCousinia species confirm the close connections between the Iranian and the Turkestanian mountains as centres of origin and conservation of palaeo-xeromorphic mountain floras, contrasting with the Turanian lowland flora.

    Notes: Abstract The shape and the mode of dehiscence of the capsule had been regarded as good differential characters betweenAcanthophyllum and related genera.—Studies of these characters, including the shape of the ovary, in species ofAcanthophyllum, Diaphanoptera, Ochotonophila andScleranthopsis show, however, that they cannot be used as differential characters for the genusAcanthophyllum.

    Notes: Abstract Galium serpylloides agg. comprises a group of locally endemic, disjunct and vicarious taxa in the (sub)alpine zone of the W. Himalaya, from W to E:G. gymnopetalum, G. lahulense, G. serpylloides s. str.,G. saipalense, andG. nepalense. Four of these are new to science;G. serpylloides is newly typified. The main characters of the five species are compared and illustrated, their affinities and evolution are discussed, and a map of distribution is presented.

    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Hypericum dogonbadanicum Assadi, a local species from theQuercus brandtii forests of the Zagros Mountains in south-western Iran, belongs to sect.Campylosporus (Spach)R. Keller and is most closely related to a Socotran endemic,H. socotranum Good subsp.smithii N. Robson. Despite the inclusion of these forests in the Irano-Turanian Element of the Iran flora byZohary (1963),H. dogonbadanicum appears to belong rather to the Mediterranean dwarf-shrub maquis type of community and therefore to be a member ofZohary's (1963) Mediterranean/Irano-Turanian group of Iranian species.—The key position of the Socotran endemics to the understanding of the inter-sectional relationships is discussed.

    Notes: Abstract A character analysis reveals a clearly intermediate position of the tetraploidV. persica (2n = 28) between the two diploid speciesV. polita andV. ceratocarpa (both 2n = 14) which are morphologically rather different and have been placed by several authors in different sections of the genus.V. ceratocarpa is native to subhumid deciduous forests of the Caucasus and of the Elburz mountains (N. Iran);V. polita has its centre of variation in the Elburz range where it grows in therophyte habitats. Three other closely related species,V. bungei, V. siaretensis, andV. francispetae, are endemic to the Elburz range which is the main centre of diversity and variability of theV. agrestis group. This comprises all the above mentioned species and also two more European weeds:V. agrestis andV. opaca. Veronica polita, was probably originally native to open places in deciduous mountain forests, before becoming a weed in neolithic times and migrating to Europe; nowadays it has an almost world-wide distribution. The allotetraploidV. persica combines the ecological characters of its parents, the slightly xerophyticV. polita and the more mesophyticV. ceratocarpa, thus being preadapted to become a highly successful weed with a large ecological range. It has spread rapidly almost all over the world since the early 19th century.
