“…6). In a few genera the lateral staminodes and/or the labellum are reduced or absent (Rhynchanthus, Pommereschea, Nanochilus, Stadiochilus, Laosanthus, Hedychium horsfieldii, and H. bordelonianum;Smith, 1980;Newman, 1990;Larsen and Jenjittikul, 2001;Williams, Kress, and Thet Tun, 2002). Hence, the presence of well-developed lateral staminodes is a feature not shared by all members of the Zingiberoideae as recognized here.…”

The pantropical Zingiberaceae is the largest family in the order Zingiberales with 53 genera and over 1200 species. Classifications of the family first proposed in 1889 and refined by others since that time recognize four tribes (Globbeae, Hedychieae, Alpinieae, and Zingibereae) based on morphological features, such as number of locules and placentation in the ovary, development of staminodia, modifications of the fertile anther, and rhizome-shoot-leaf orientation. New phylogenetic analyses based on DNA sequences of the nuclear internal transcribed spacer (ITS) and plastid matK regions suggest that at least some of these morphological traits are homoplasious and three of the tribes are paraphyletic. The African genus Siphonochilus and Bornean genus Tamijia are basal clades. The former Alpinieae and Hedychieae for the most part are monophyletic taxa with the Globbeae and Zingibereae included within the latter. The results of these phylogenetic investigations are used to propose a new classification of the Zingiberaceae that recognizes four subfamilies and four tribes: Siphonochiloideae (Siphonochileae), Tamijioideae (Tamijieae), Alpinioideae (Alpinieae, Riedelieae), and Zingiberoideae (Zingibereae, Globbeae). Morphological features congruent with this classification and the taxonomic status of various monotypic genera are discussed.

“…Hitcheniopsis. Although the similarity of Laosanthus to Cur cuma was noted in the original description, diagnostic characters to separate Laosanthus from it were put forward as free bracts, lack of lateral staminodes, the lack of epigynous glands and anther with well-developed anther crest but no basal spurs (Larsen & Jenjittikul, 2001). The free or almost free bracts, although rare, were observed in a few Curcuma species, e.g., C. albiflora, C. oligantha (Škorničková & Sabu, 2005a).…”

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.

“…Five new genera, all from the highly diverse subfamily Zingiberoideae, tribe Zingibereae, have been described, namely Distichochlamys M.F. Newman from Vietnam (Newman, 1995), Laosanthus K. Larsen & Jenjitt. from Laos (Larsen & Jenjittikul, 2001), Cornukaempferia Mood & K. Larsen (Mood & Larsen, 1997) and Smithatris W.J. Kress & K. Larsen (Kress & Larsen, 2001) from Thailand, and Jirawongsea Picheans.…”

A new genus of Zingiberaceae from Vietnam, Newmania N.S. Lý & Škorničk., with two species Newmania serpens N.S. Lý & Škorničk. and N. orthostachys N.S. Lý & Škorničk., is described and illustrated. Its relationship with Haniffia Holttum and phylogenetic position in the tribe Zingibereae is investigated using nrITS and trnK and matK plastid sequence data. The phylogenetic position of Kedhalia C.K. Lim, another recently described ginger genus from the same tribe, is also discussed briefly.
