“…According to Carpenter and Smith (1975), variations in stoma-tal frequencies have taxonomic importance at a generic level. After the quantitative investigations of stomatal frequency and index of the species examined, there was a remarkable variation between the two genera showing that these characters were significant at the genus level supporting of Patil and Patil (1987), Ogundipe at al. (2009), Onuminya et al (2020).…”

The tribe Bauhinieae is the largest and most taxonomically complex group within the subfamily Cercidoideae. They possess the most distinguishable morphological features but are the most variable group. Here, we explore the phylogenetic relationship of the tribe Bauhinieae using morphological, anatomical and molecular data (ITS, rbcL, trnL-F, ITS+rbcL+trnL-F). Relationships inferred from morphological, anatomical and molecular data revealed congruent result, a non-monophyletic Bauhinia and Piliostigma group. The leaf epidermal shape in all Bauhinia species examined are polygonal with straight cell walls except B. tomentosa, which has an undulating cell wall. Stomatal types observed vary between the two genera studied. Bauhinia species has paracytic stomata while Piliostigma species exhibited hemiparacytic stomata. Dendrogram generated revealed the interrelationship between the species at a distance value of 80. Bayesian analysis revealed a high resolution of species and posterior probability. The strict consensus tree for all the tested gene regions revealed a polyphyletic Bauhina divided into three major clades. The Piliostigma group exhibited a paraphyletic and polyphyletic relationship within the Bauhinia group at high support values. B tomentosa exhibited a closer relationship with Piliostigma species. These results support the proposition to divide members of the large Bauhinia s.s group into subclades. This study has attempted to elucidate the unresolved species and genus level taxonomy of the tribe Bauhinieae. However, more variable gene regions in addition to broader species sampling should be considered for further phylogenetic patterns of this taxon.

“…After comparing the data on difference between longest and shortest chromosome (L-S), the ratio of longest to shortest chromosome (L/S) and TCLH value (Patil et al 1987) amongst these species it can be said that C. kolhapurense and C. tuberosum come near to each other than to any other species.…”

“…The other grades common in Chlorophytum species are 2b (C. glaucum and C. orchidastrumϭC. nimmonii, Patil et al 1987) and 3b (C. arundinaceum, Pahuja and Kumar 1969). The detailed karyotype analysis of C. kolhapurense showed that, out of the 8 pairs of chromosomes 4 pairs have submedian centromere while other 4 pairs possess median centromere.…”

“…The detailed karyotype analysis of C. kolhapurense showed that, out of the 8 pairs of chromosomes 4 pairs have submedian centromere while other 4 pairs possess median centromere. Subterminal chromosomes are relatively more in C. nimmoni, C. glaucum, C. glaucoides, C. khasianum, C. nepalense and C. comosum (Patil et al 1987, Naik 1977a. In case of C. malabaricum and C. tuberosum only 1 pair has subterminal centromere while in C. bharuchae all chromosomes have submedian centromere (Naik 1977b).…”

SummaryThe genus Chlorophytum Ker-Gawl, with about 216 species, is distributed mainly in the Old World tropics especially in Africa and India. In India 17 species represent the genus. This genus has attracted the interest of scientific community owing to the presence of pharmacologically important saponins. Recently described species, C. kolhapurense Sardesai, S. P. Gaikwad & S. R. Yadav was studied cytologically, the chromosome number was 2nϭ16 and nϭ8 and the karyotype was symmetrical.

Karyology of the Asparagales and Liliales is reviewed with references to their morphology, embryology, DNA analyses, and other aspects. Asparagaceae, Ruscaceae, Dracenaceae, and Nolinaceae may share a common ancestor with x = 10, and Tecophilaeaceae, Cyanastraceae, and Ixioliriaceae with x = 12. Tricyrtis (Uvulariaceae) is karyologically similar to Tulipa, Gagea (Liliaceae) and Smilax (Smilacaceae); Clintonia (Uvulariaceae) to Medeola (Liliaceae); Prosartes and Streptopus (Uvulariaceae) to Calochortus (Calochortaceae); Scoliopus (Trilliaceae) to the Medeola‐Clintonia group or Calochortus‐Prosartes‐Streptopus group. The original chromosome size of the Asparagales and Liliales may be estimated as small.
