The chromosome numbers and karyotypes of eight species the genus Allium distributed in Turkey were analyzed. These taxa are A. armerioides Boiss., orientale stamineum tuncelianum (Kollmann) Özhatay, B.Mathew & Şiraneci, subakaka Razyfard Zarre, muratozelii Armağan, dumanii Koyuncu Koçyiğit colchicifolium Boiss. Four them (A. armerioides, tuncelianum, dumanii) endemic Turkey. all studied determi...

A new combination in the rank of subspecies, Campanula tridentata Schreb. subsp. ruprechtii (Boiss.) Ogan., distributed Armenia, Nakhchivan Republic and Iran is published. The lectotype name designated.

Piperazirum, isolated from Arum palaestinum Boiss, was originally assigned as r-3,c-5-diisobutyl-c-6-isopropylpiperazin-2-one. The reported structure was synthesised diastereoselectively using a key nitro-Mannich reaction to set up the C5/C6 relative stereochemistry. The structure was unambiguously assigned by single crystal X-ray diffraction but the spectroscopic data did not match those repor...

In this survey, the chromosome counts of eight Nepeta L. species were investigated and karyotypic diversity among these was studied. The examined belong to N. cephalotes Boiss. group, namely eremokosmos Rech.f., gloeocephala Rech. f., Boiss., pungens (Bunge) Benth., ispahanica mahanensis Jamzad & Simonds, hormozganica denudata Benth. collected from different habitats in Iran. ploidy levels,...

Verbascum delphicum Boiss. & Heldr. subsp. cervi Zografidis (Scrophulariaceae, Scrophularieae) is described as a subspecies new to science and illustrated. It is narrowly distributed in the Greek National Park of Mt Parnitha (Attica, Greece) with a very small population size. The new subspecies is a seldom-collected taxon, previously overlooked and misidentified as consubspecific with the auton...
