“…According to band‐sharing analysis, C. bhatii and C. angustifolia could contribute to its endecaploid genome, but this possibility was not supported either by other analyses or by morphological similarity. This species is endemic to Sri Lanka and, although it is morphologically close to the south Indian C. cannanorensis of genome size group II, it possesses some unique features; for example, it is the only species in Curcuma with a chromosome number of 2 n = 77 (Leong‐Škorničková et al ., 2007, 2010; Škorničková, 2007). The seed‐setting, narrow endemic species of the Western Ghats, C. bhatii , differed from other seed‐setting Indian Curcuma spp.…”

Interpretations of names and circumscriptions of taxa are based on detailed studies of relevant type specimens and localities in the field, including numerous populations at localities of nomenclatural types (Leong‐Škorničková, Šída & Marhold, 2010 and references therein). Two to ten individuals per population and one to three populations per taxon were analysed.…”

The relationships between genome size and the systematic and evolutionary patterns in vascular plants are equivocal, although a close relationship between genome size and evolutionary patterns has been previously reported. However, several studies have also revealed the dynamic nature of genome size evolution and its considerable 'ups' and 'downs'. Thus, in this study, the phylogenetic relationships among three previously revealed genome size groups and among species of the highly polyploid genus Curcuma were evaluated using AFLP. Our results suggest two main lineages within Indian Curcuma reflecting evolution of genome size. The first one includes hexaploids and higher polyploids of the previously recognized genome size group I, and the second one includes mainly hexaploids of genome size groups II and III. Within genome size group I, relationships among species seem to be influenced by reticulate evolution and higher polyploids are likely to be of allopolyploid origin. Reproductive systems in Indian Curcuma vary considerably among ploidy levels and these differences considerably affect morphological and genetic variation. In general, clonally reproducing species are expected to exhibit low genotypic diversity, but, at the same time, species of allopolyploid origin are expected to maintain higher levels of heterozygosity compared with their progenitors. We investigated intra-populational genetic variability in Curcuma spp. to evaluate whether mode of reproduction or ploidy represent the main factor influencing the degree of genetic diversity. We found that hexaploid species exhibited significantly higher genetic diversity than higher polyploids (9x, 15x). Our results suggest that this genetic diversity pattern is largely influenced by the mode of reproduction, as higher polyploids reproduce exclusively vegetatively, whereas hexaploids reproduce mainly sexually.

In this paper we provide a thorough overview of past attempts at infrageneric classification of the genus Curcuma (Zingiberaceae). As the recent results of phylogenetic analysis of the genus confirmed that previous infrageneric classifications are not tenable, we provide a revised circumscription of Curcuma with an outline of new infrageneric classification into three subgenera, C. subg. Curcuma, C. subg. Ecomatae and C. subg. Hitcheniopsis including lists of species to be included in each subgenus. Three previously recognized genera, Laosanthus, Smithatris and Stahlianthus, are sunk to Curcuma and two species previously recognized in the genus Hitchenia, H. caulina and H. glauca, are transferred/re-recognized to Curcuma. The previously proposed transfers of the monospecific genus Paracautleya, Hedychium scaposum (Kaempferia scaposa, Monolophus scaposus) and Kaempferia candida, to Curcuma are also confirmed. All connected nomenclatural innovations, corrections and outstanding typifications, inclusive those of infrageneric names, are effected in this paper. A list of excluded names originally described as members of Curcuma, but now accepted as members of other genera is also included.

Cassumunar is a well‐known and widely cultivated medicinal ginger. Historically, many names have been applied to this species. Over the past two decades, Zingiber montanum (≡ Amomum montanum) has been mostly accepted as the correct scientific name for Cassumunar ginger in spite of numerous discrepancies between the protologue and the plants to which the name was applied. We re‐investigated the identity, taxonomy and nomenclatural history of Z. montanum, Z. purpureum and Z. cassumunar and their synonyms. We show that the correct name for Cassumunar ginger is Z. purpureum and that Z. montanum is a different species. A specimen at C previously regarded as the holotype of A. montanum is not original material, and represents Z. purpureum, which partly explains the confusion between these two names. Zingiber montanum is characterized by scarlet inflorescence bracts and flowers with labellum and lateral staminodes being dark purplish‐red, and mottled cream‐white. Unlike Z. purpureum, Z. montanum is not known in cultivation and has no known medicinal properties. Zingiber newmanii, Z. nudicarpum and Z. peninsulare are placed in synonymy with Z. montanum, expanding the distribution significantly in Southeast Asia and into China. Zingiber purpureum is readily distinguished from Z. montanum by dark red to maroon, purplish or almost brown bracts often with greenish margins, and flowers with cream‐white labellum and lateral staminodes. Zingiber cassumunar, Z. cassumunar var. subglabrum, Z. cliffordiae, Z. paucipunctatum and Z. pubisquamum are treated as synonyms of Z. purpureum. Neotypes are designated for A. montanum and Z. purpureum, and lectotypes are designated for Z. cassumunar, Z. cassumunar var. subglabrum, Z. cliffordiae, Z. peninsulare and Z. pubisquamum.
