The genus Allium L comprises over 1000 species with important nutritional, medicinal and horticultural applications. The natural flora of Kazakhstan is rich in Allium species, including the wild long-pointed onion, A. longicuspis and cultivated A. sativum garlic varieties. It has been hypothesized that A. longicupis is ancestral to A. sativum. We i...

Urbanisation is one of the major drivers of global species extinction. Botanical gardens, being diverse green oases in urban landscapes, have a high potential as refuge areas for wild species. How many and which organisms use the gardens as secondary habitats has been little studied. Twenty botanical gardens in Germany, Austria and Switzerland part...

In this paper, we present nomenclatural novelties required in the course of the preparation of the second, revised version of the checklist of vascular plants of Asian Russia. The first version was published in 2012 (Baikov 2012). At the family level, we accepted the modern classification systems (APG IV for flowering plants, PPG I for lycophytes a...

Allium pallasii Murr. var. nitidulum Fisch. et Regel was assigned species status (A. nitidulum Fisch.) in 1853 by Ledebour in “Flora Rossica”, being considered as a synonym of Allium pallasii but with no description. Then in 1887 E. Regel considered it as a variety: “Allium pallasii Murr. ß nitidulum teste Rgl.” and highlighted its morphological di...

A new species, Allium sulaimanicum, is described from northern Balochistan and southern Khyber Pakhtunkhwa in Pakistan based on morphological, molecular, and cytological studies. The new species is characterised by long runner-like cylindrical rhizomes of adult plants, cylindrical bulbs, linear leaves with minute soft hairs along veins, campanulate...

The Euro-Siberian steppe flora consists of warm- and cold-adapted species, which may have responded differently to Pleistocene glacials and interglacials. Genotyping-by-sequencing individuals from across the distribution range of the pheasant’s eye (Adonis vernalis), we aimed to gain insight into steppe florogenesis based on the species’ evolutiona...

In the Grotta di Fumane (GdF), five figuratively painted vault fragments were found in the debris of the cave floor. Dating to 35,000 B.P., the paintings are among the oldest known paintings in Europe. The paintings have been dated to an early phase of the Aurignacian. This should explain the “primitive” character of the works. We interpret the pai...

Seed testa sculpture of 21 species were described for the first time in this study. According to our results, the straight anticlinal wall and one la...

Constituting one of Earth’s major biomes, steppes are characterised by naturally treeless extra-tropical vegetation. The formation of the Eurasian steppe belt, the largest steppe region in the world, began in Central Asia during the Neogene. In the glacial stages of the Pleistocene, steppe displaced forest vegetation, which in turn recolonised the...

In-situ conservation of species of wild celery – Example for genetic resources of Crop Wild Relatives (CWR) Crop Wild Relatives (CWR) species are an indispensable and at the same time threatened genetic resource of plant breeding. The study uses wild species related to celery to demonstrate how genetic resources of CWR can actively be maintained in...

Molecular markers presented clear evidence that A. senescens subsp. glaucum is in the strict sense only distantly related to A. senescens and should be accepted at species rank. As the binomen A. glaucum refers to the A. schoenoprasum alliance, the name A. baicalense must be applied.

Crop Wild Relatives (CWR) species are an indispensable and at the same time threatened genetic resource of plant breeding. The study uses wild species related to celery to demonstrate how genetic resources of CWR can actively be maintained in their natural surroundings (in situ). To this end occurrences are identified within the scope of a model an...

We hypothesized that the spatial pattern of genetic variation in different ecological groups of steppe plant species is not similar. To test this hypothesis, we studied genetic variation of the typical steppe plant Goniolimon speciosum (Plumbaginaceae), which is spread across the whole of the Asian steppe, and compared it with the published data on...

In the living Allium collection of the South Siberian Botanical Garden of the Altai State University, Barnaul (Russia), among the species Allium tulipifolium and A. robustum (A. subg. Melanocrommyum sect. Decipientia), several morphologically intermediate plants grown from seeds were found. We assumed they could result from spontaneous hybridizatio...

Allium palaestinum, a long-forgotten taxon of arid Israel and Jordan, is re-described here. The new description is based on Kolmann's work in 1971 and on living plants and fresh herbarium specimens. Independence of the species is confirmed not only by differing morphological and ecological features of the nearest related Allium species, but also by...
