Polyploidy is common in the ginger family Zingiberaceae. The aims of the present paper are (1) to provide a general introduction on species diversity with emphasis on conservation; (2) to highlight the human-use significance of this family, focusing on the two major genera, Zingiber (ginger) and Curcuma (turmeric); (3) to present chromosome number data from 45 natural and cultivated Curcuma taxa from Thailand, of which polyploids are predominant; and (4) to describe our own work on cytotaxonomy of selected Thai Curcuma species. We obtained somatic chromosome numbers from root tips and analysed meiotic chromosome behaviour from flowers. We also used the molecular cytogenetic method of ribosomal gene mapping on chromosomes to infer mechanism of polyploidization and reveal genomic relationships among closely related species. The main results of our cytogenetic studies include the following. The most sought-after medicinal Curcuma cultivars growing on a large-scale basis are secondary triploids, so as taxa in natural habitats that are harvested for local utilisation. These triploids are sexually deficient, due to meiotic pairing abnormalities, but they are propagated asexually via rhizomes. The ribosomal mapping results indicate natural triploidization process via hybridisation, either within populations or across the species boundaries.

“…While the chromosome numbers of these four species were studied by some scientists, i.e. Eksomtramage et al (2002), Sirisawad et al (2003), Saensouk and Saensouk (2004), Khamtang et al (2014), , Saenprom et al (2018), Mood et al (2020), Nopporncharoenkul et al (2020), Moonkaew et al (2020), Ikeda et al (2021), Saensouk (2021a, b, 2022). Two species (B. rotunda and K. rotunda) from these seven Zingiberaceae species were studied with the karyotype formula by Saenprom et al (2018), and Saensouk and Saensouk 2022.…”

Abstract. Saensouk P, Saensouk S, Phechphakdee T, Ragsasilp A. 2022. Cytogenetic study in seven species of Zingiberaceae family from Bueng Kan Province, Thailand. Biodiversitas 24: 68-77. Bueng Kan province is located in the Northeast Thailand. The family Zingiberaceae in Bueng Kan Province was found to be a highly diverse plant. The aim of this study was to study the chromosome numbers, fundamental number (NF), karyotype form and ideogram analysis of seven species in the family Zingiberaceae from Bueng Kan province, Northeast Thailand. The seven species of Zingiberaceae family-namely Boesenbergia rotunda (L.) Mansf., Curcuma aeruginosa Roxb., Etlingera elatior (Jack) R.M.Sm., Kaempferia elegans Wall., Kaempferia pulchra Ridl., Kaempferia rotunda L. and Zingiber montanum (J.Koenig) Link ex A.Dietr. in this study have been recognized the cytogenetic study including the chromosome number from root tips, karyology, NF, symmetrical karyotype, RL, CI, and ideogram. The chromosome numbers of all species were reported between 2n = 20 and 68. The NF of six species was reported for the first time. The symmetrical karyotype formula has been recognized as a symmetrical karyotype (four species) and an asymmetrical karyotype (three species). The karyotype formula of five species was reported for the first time. The ideogram of all species was provided for the first time. The cytogenetic data of all species in this study can be used for identification.

“…Currently, 13 species are recognized in Kaempferia subgenus Protanthium which 12 species were distributed in Thailand, there are Kaempferia rotunda L. (Linnaeus 1753), K. simaoensis Y.Y. Qian (Qian 1995;Nopporncharoenkul et al 2016), K. grandifolia Saensouk & Jenjitt. (Saensouk and Jenjittikul 2001), K. lopburiensis Picheans.…”

Abstract. Boonma T, Saensouk S, Saensouk P. 2022. Kaempferia sipraiana (Zingiberaceae), a new species from Thailand and a new record of Kaempferia pseudoparviflora for Myanmar. Biodiversitas 23: 2203-2211. Kaempferia sipraiana Boonma & Saensouk, a new species of Kaempferia subgenus Protanthium (Zingiberaceae) from northern Thailand and K. pseudoparviflora Saensouk P. & Saensouk, a new record species of Kaempferia subgenus Kaempferia for Myanmar are described, illustrated, and photographed. The dominant characters of Kaempferia sipraiana were leaves narrowly elliptic, green with short white stripes arranged parallel along the leaf edges, between the midrib and both sides of the edges, apex acuminate with slightly mucronate, base attenuate-oblique; peduncle glabrous; bracts apex mucronate, glabrous, red with dark red veins; bracteoles glabrous; floral tube shorter than calyx; calyx glabrous; staminodes oblanceolate, apex 3-lobes like curly brackets; labellum white at the base with pinkish purple in the middle gradually fade to pale pink and to reach to white tip and edge respectively, apex 3-lobes like curly brackets, each lobe 3.0–3.3 cm long; apex 4 lobes, outer lobes acute, inner lobes obtuse rarely combined to truncate; stigma with pink lips. The dominant characters of K. pseudoparviflora were one leaf and dark green with light grey markings, the inflorescence looks like inflorescence of K. parviflora. The information on vernacular name, distribution, phenology, ecology, conservation status, specimens examined, and an identification key to both species of Kaempferia in Thailand is revised and presented.
