Leaflet Trichome Micromorphology In The Dolentes-Brevipedes Taxonomic Complex (Mimosa L., Mimosoideae), Mariana Grohar, Sonia Rosenfeldt, Matias Morales
Turkish Journal of Botany
We studied leaflets of 18 taxa of the genus Mimosa, specifically the Dolentes-Brevipedes taxonomic complex, focusing on micromorphology, type, shape, and density of trichomes. Within the nonglandular trichomes we described 3 types of nonbranched and 2 types of branched trichomes. We also described 2 types of stalked glandular trichomes, extending the recent classifications of trichomes in Mimosa. Multiseriate trichomes with lateral projections, which resemble incipient branching, are described here for many taxa. Most studied taxa have pubescent leaflets and show great variability in trichome density values. We also found 3 different types of blade margins with variation in type, alignment, …

Astragalus unalii Çeçen, Aytaç and Mısırdalı, sp. Nov. (Fabaceae, sect. Malacothrix Bunge) is described as a new species from Karadağ (Karaman Province) in southern Anatolia and compared with its relatives growing in steppe vegetation. The new species is close to A. Tauricola Boiss. And A. Adiyamanensis Podlech and M.Ekici, endemic and growing in central and southern parts of Anatolia, Turkey.
