The aim of this work was to determine the cytogenetic characteristics of Brazilian Lippia alba (Mill) N. E. Brown and Lantana camara Plum. that could be useful for future characterization of these genera. Our analyses revealed that Li. alba has 2n=30 chromosomes consisting of ten metacentric and five submetacentric pairs, while La. camara has 44 metacentric chromosomes. The large blocks of heterochromatin seen in both species suggest an apomorphic condition. Six 45S rDNA sites were detected in both species by fluorescence in situ hybridization (FISH). Two and four 5S rDNA sites were observed in Li. alba and La. camara, respectively. Meiotic analysis revealed a normal chromosomal behaviour. The number of chromosomes and the presence of 45S rDNA and 5S rDNA sites do not exclude a possible polyploid origin. The cytogenetic differences between La. camara and Li. alba may be useful markers for differentiating these species.

“…Qu et al (1998) used meiotic analysis to study Vaccinium species and observed tetrasomic inheritance, as well as the formation of bivalents and multivalents by random pairing among four homologues and a high fertility, all in the same newly formed hybrid. Studies with Lantana camara populations from South Africa, the Caribbean and India have shown that this species is tetraploid (x = 11) and always has uni-, bi-, triand multivalents, (Tjio 1948;Sen and Sahni 1955;Raghavan and Arora 1960;Arora 1961;Sinha and Sharma 1984;Spies 1984;Sanders 1987;Ojha and Dayal 1992;Sinha et al 1995). In Lippia L, the high degree of ploidy has been related to the occurrence of chromosomal abnormalities and, consequently, to abnormal development of the seeds (Poggio et al 1993).…”

“…These divergences indicate that the taxonomic position of Verbenaceae species remains unresolved (Raj 1983;Sinha and Sharma 1984). Additionally, the natural occurrence of hybrids and polyploids hinders the precise classification of some taxa (Spies 1984;Sanders 1987;Ojha and Dayal 1992;Rueda 1993;Sanders 2001).…”

“…Andrada et al (1998) observed meiotic abnormalities in Lippia fissicalyx Tronc., including univalents, multivalents and a high frequency (82.4%) of abnormal pollen and suggested a relationship among these characteristics and the level of ploidy. In Lantana L. species, an unequal distribution of chromosomes has been observed during anaphase (Sinha and Sharma 1984;Sinha et al 1995). CorazzaNunes et al (1995) also reported abnormal segregation of the chromosomes and spindle alterations in meiotic cells of Aloysia lycioides Cham.…”

Meiotic analysis of two putative polyploid species of Verben-aceae from Brazil

-The natural occurrence of hybrids and polyploids hinders the precise identification of some taxa in Verbenaceae (Lamiales). Since meiotic studies are useful for understanding the chromosomal behavior of plant species, we have examined the meiotic stages and chromosomal behavior of Lippia alba (Mill) N. E. Brown and Lantana camara Plum. in Brazil. Lippia alba and Lantana camara, had normal stages of meiosis, including interphase, leptotene, zygotene, pachytene, diplotene, initial diakinesis, diakinesis, metaphase I, anaphase I, telophase I, prophase II and telophase II. Fifteen and 22 bivalents were observed during diplotene and diakinesis in L. alba and L. camara, respectively. The chromosomes segregated normally during anaphase I, telophase I and II. The regular meiotic behavior seen in L. alba and L. camara indicated that polyploidy was established by a diploid-like behavior in meiosis, although this did not exclude a possible diploid origin.

“…Cytological studies on different populations of Lantana have reported basic chromosome numbers to be 11 & 12 (Henderson 1969, Sinha andSharma 1984) and 8 & 11 (Moldenke 1983). They have also pointed out the existence of polyploid series in the genus based on reported base numbers.…”

Lantana camara L. (sensu lato): an enigmatic complex

Lantana camara L., considered among the world's worst invaders is in identity crisis and contentiously referred as Lantana camara L. (sensu lato). Taxonomic ambiguity in L. camara L. (sensu lato), a species complex is one of the grim caveats behind incompetence of its management efforts. Recognizing the extent of variability within the complex, we aim to highlight the need to circumscribe its composition to bring effective management and control efforts into practice. There is a need for clear terminology to examine weedy, naturalized and/or invasive complex constituents that have been placed under the contentious umbrella of 'L. camara L. (sensu lato)'. The time is ripe for invasion ecologists, cytogeneticists and conservationists to collaboratively focus on disentangling the complex and integrate their knowledge and expertise into management and control programs.
