“…The cytological report of two species Crotalaria Inchnosema, n = 8 , and Crotalaria longfoliolata, n = 8, are reported here for the first time. Eriosema glomeratum, the report o f n = I 1 agrees with the previous reports of FRAHM-LEVIFELD (1969) andHUSAINI andGILL (1985) while the present report of Eriosemapseudoleoides is n = 10 conflicts with the earlier reports of n = 11 by FRAHM-LELI- VELD (1953VELD ( , 1957, GILL and HUSAINI (1984) and TURNER and FEARING (1959). The report of Indigofera milbraediana (n = 8 ) and Indigofera pdchra, (n = 8) agrees with the previous report FRAHM-LELIVELD (1960, 1966 and MIEGE (1962).…”

Chromosome numbers of twenty‐five weed species belonging to the genera Crotalaria, Eriosema, Indigofera and Sesbania were determined for the first time from Jos Plateau, Nigeria. Two species of Crotalaria, C. lachnosema and C. longifoliolata are reported cytologically for the first time, while the chromosome number of the Crotalaria recta, (n = 7) and Eriosema psoraleoides, (n = 10) do not agree with the previous reports. Chromosome number of the rest of the species agrees with their previous cytological reports.

“…From a karyological point of view, several authors have studied the genus, but chromosome numbers are known for only 28% of the taxa so far described, mainly for those from Asia and Africa (Chennaveeraiah & Patil, 1973; Gupta & Gupta, 1978; Raina & Verma, 1979; Verma, Kesavacharyulu & Raina, 1982, 1984; Verma & Raina, 1983; Husaini & Iwo, 1992). Among American species, the karyotypes for some Mexican (Palomino & Vázquez, 1991) and Brazilian populations (Cotias de Oliveira & Aguiar‐Perecin, 1999) have been described, in addition to a few chromosome numbers reported for populations in the United States (Windler, 1974), Colombia (Shibata, 1962) and Argentina (Fernández, 1977; Bernardello, Stiefkens & Piovano, 1990).…”

Karyotypes of 18 populations belonging to eight of the southernmost species of South American Crotalaria were examined. All had x = 8, except C. incana which had x = 7. Diploid, tetraploid and octoploid species were found. The octoploid is a new record and is the highest ploidy level detected so far in the genus. Species within the same ploidy level could be distinguished by quantitative karyotype parameters and by the size and position of the satellites. From an evolutionary point of view, our results support a decrease of the basic chromosome number by dysploidy. Polyploidy is one of the more important mechanisms of chromosome change, even though some structural rearrangements may explain variations of the karyotype formula. Gigas effects, due to polyploidy, were evident in the length of the stomatal guard cells and in pollen size, but were less clear in seed weight. Nucleotype effects, caused by the DNA quantity in a nucleus, were also evident for pollen and stomatal guard cell size and seed weight, although only in diploids with x = 8 for the latter character. Chromosome data are further discussed in the light of the infrageneric systematic arrangement.

“…Taia, (2004) examined seeds of some genera as Medicago L., Melilotus Mill., Ononis L., Trifoliun L., and Trigonella L. intention to evaluate the correlation among taxa (Zoric et al, 2009). Husaini and Iwo (1992) worked extensively on Crotalaria L. and reported the genus phenological information which is based on conventional taxonomic methods.…”

Distinguishable morphological qualitative and quantitative traits for 310 native taxa of 46 genera within the Fabaceae family were selected. The taxa were treated numerically analyzed as OTUs; based on the selected characteristics variations the UPGMA dendrograms by the MVSP windows program were constructed. The relationships among studied taxa were determined and illustrated. The results exhibited that all taxa are monophyletic due to the similarity in the specific characteristics of the family, the divergences among groups, or among taxa of a single group caused by dissimilarities. At different levels, three groups and six sub-groups were set among the genera, the genus Astragalus L. had the most distance relationship from other genera at level GGSc=0.67, due to the abundance of its taxa and a large number of differences among them. The relationship degrees among all studied taxa except Astragalus taxa analyzed, two groups and seven subgroups were identified at levels GGSc= 0.74 and GGSc= 0.77, detailed and illustrated.
