Cytogenetic characterization of Schinus terebinthifolius Raddi (Anacardiaceae) accessions from Rio Grande do Sul State, Brazil
This study aimed to perform chromosomal characterization of 22 accessions of S. terebinthifolius native to Rio Grande do Sul, aiming to verify the intraspecific variability in this species, besides the conservation and sustainable use of this species.
On the treatment of Merendera and Bulbocodium ( Colchicaceae ) as separate genera On the treatment
The author concludes that the status of Merendera and Bulbocodium should be preserved and they should be recognized as independent genera.
Chromosome numbers of some indigenous tree species of Ethiopia

Insights into the dynamics of genome size and chromosome evolution in the early diverging angiosperm lineage Nymphaeales (water lilies).
A comprehensive overview of genome sizes and chromosome numbers in these early diverging angiosperms is presented by combining additional data from Amborellales and Austrobaileyales.
Flow cytometric and karyological analyses of Calendula species from Iberian Peninsula
- BiologyPlant Systematics and Evolution
The obtained genome size values and their variation are discussed in the light of the theories proposed for the speciation of the genus, with events of hybridization, genome duplication and dysploidy being hypothesized to play a major role in the evolution of this genus.
Karyomorphology of Flemingia nilgheriensis (Baker) Wight ex T. Cooke: An Endemic from Western Ghats

Chromosome numbers of the Kuwaiti flora, III.
- Environmental Science
Chromosome numbers (somatic and gametic) of 21 species of eight families of angiosperms, collected in the wild in Kuwait, are reported, most of them are the first counts in Kuwaiti populations.
Polyploidy determines the stage of invasion: clues from Kashmir Himalayan aquatic flora
- Environmental ScienceActa Physiologiae Plantarum
A clear pattern is depicted that non-invasive species are disproportionately more diploids with lower ploidy ratios, while invasive plant species on the contrary exhibit higher chromosome counts, thereby being predominantly polyploids.
Meiotic Studies in Some Members of Tribe Andropogoneae (Poaceae) from Semi Desert Area of North India
Five species show meiotic abnormalities in the form of multivalent, laggards, bridges, unoriented bivalents, etc. and the other 15 species have normal meiotic behavior.
