Abstract: Since the rise of the “Revolution of Molecular Cladistics” for plant taxonomy in 1990s, traditional plant classification systems based primarily on macromorphological characters have gradually been substituted with molecular plant classification systems. In the process of revising the classification system and world checklist of families and genera of angiosperms on the basis of the latest research in molecular phylogenetic systematics, a new batch of additional names of infrafamilial and hybrid taxa were found to require publication. In this paper, 78 names are newly published for the infrafamilial and hybrid taxa in 26 families. These taxa include nine subfamilies (Alyxioideae, Amsonioideae, Hunterioideae, Melodinoideae, Manihotoideae, Suregadoideae, Coptosapeltoideae, Amphorogynoideae, and Cervantesioideae), 14 tribes, 20 subtribes, 11 nothogenera, 17 nothospecies, and seven nothosubspecies. In addition, a replacement name, Zidornia (Asteraceae) and two new genera, Sinammatia, and Ukrainodoxa (both Oleaceae), as well as new combinations for nine species and five subspecies accordingly, are also proposed. Lectotypes are designated for Syringa × diversifolia, Syringa × henryi, Syringa josikaea, and Syringa yunnanensis, and neotypes are designated for Syringa × nanceiana and Syringa × prestoniae. Moreover, the former lectotypification for Syringa wolfii is rejected. These updates help us present a renewed classification system of angiosperms (especially for the flora of China and East Asia) kept with the Linnaean paradigm.

Abstract: The study was carried out on Variation in Wood Specific Gravity of Selected Species in three zones of Kano State, Nigeria. The study focuses on the effects of wood volume, mass, wood density, and specific gravity on two different tree species name Mango (Mangifera indica) and Tamarind (Tamarindus indica). The result shows that, the tree species with the highest mass was recorded in tamarind in sample 5 with 169.0g. The highest tree volume recorded was mango tree in sample 6 with 198.91cm3. The wood species with the highest density was recorded in tamarind in sample 2 with 1.83 g/cm3. The wood species with the highest specific gravity was recorded in tamarind in sample 2 with 1.83. The research found that Tamarind has the highest specific gravity making it suitable for various application. Wood specific gravity is an important wood property that influences timber quality, mechanical strength, biomass estimation, and carbon storage. This study assessed variations in specific wood gravity of Mango (Mangifera indica) and Tamarind (Tamarindus indica) collected from three zones of Kano State, Nigeria. Wood samples were obtained from mature trees and analyzed for mass, volume, density, and specific gravity. Comparative statistical analysis was used to evaluate differences between the two species. The results showed significant variation in wood properties between the species. Tamarind exhibited higher density and specific gravity values than Mango. The findings suggest that Tamarind wood is more suitable for heavy-duty applications requiring dense and strong timber, whereas Mango wood may be preferred for applications where lighter wood is advantageous. This study can aid researchers in selecting higher quality timber for industrial sector and provide information for selecting wood component for implement and tools.
