Abstract
- An examination of the diversity of Zingiberaceae in Thailand led to the discovery of two undescribed taxa within the genus Kaempferia: K. sakolchaii P. Saensouk, Saensouk & Boonma, a newly described species, and K. phuphanensis var. viridans P. Saensouk, Saensouk & Boonma, a novel variety. Additionally, our investigation encompassed the chromosome numbers, karyotypes, and pollen morphological characteristics of these taxa. Both taxa share a chromosome number of 2n = 22, accompanied by distinctive karyotype patterns. Kaempferia sakolchaii displays a karyotype of 12m + 10sm chromosomes, while K. phuphanensis var. viridans presents a karyotype of 10m + 10sm + 2st chromosomes. The pollen grains of K. sakolchaii and K. phuphanensis var. viridans are monads, spheroidal in shape, radially symmetrical, apolar, inaperturate, and exine sculpturing irregularly arranged elongated ornamentation elements with verrucate features. This comprehensive analysis provides valuable insights into the taxonomic classification of these two taxa, enriching our understanding of Zingiberaceae diversity in Thailand. [ABSTRACT FROM AUTHOR]
