We present a critical revision of information about rare and endangered endemic species Salvia baldshuanica (Lamiaceae), included in the Red Books of the USSR and Tajikistan. As the nomenclatural type had been missing, we assembled information on the original herbarium material performed a proper typification of the species name. A chorological analysis of the species distribution in Middle Asia was carried out. To assess the state of the current natural populations, a topographic mapping of localities (Sanglok mountains, two isolated local populations; Sarsaryak ridge, one local population) was made. A narrow edaphic confinement of plants of this species to gypsum-bearing mountain soils has been established. A taxonomic assessment of the key morphological traits of S. baldshuanica confirmed at least the sectional level of its position within the subgenus Leonia. The species was found in nature only three times – in 1883, 1937 and 1979, which confirms its exceptional rarity and high scientific interest.
The Tian Shan and Pamir-Alay mountains of Central Asia are generally regarded as the primary center of diversity of Tulipa species, but a comparative morphological description of Central Asian Tulipa species is still lacking. To fill the existing gap, we studied 48 Tulipa species found in Central Asia plus one outgroup (Erythronium caucasicum) for 24 morphological characters of bulbs, leaves, stems and flowers. The obtained data matrix was subjected to a cladistic analysis. Although bootstrap values were low, the morphology-based tree more or less corresponded to previous classifications, except for the placement of sect. Clusianae and T. butkovii.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
