A specimen from relevant literature (Saensouk et al. 2007, Xayaburi Province is reported from Lao PDR. Yupparach et al. 2019), it was identified as Color photographs of the species are provided. C. larsenii. Cornukaempferia larsenii is easily The genus Cornukaempferia Mood & K. distinguishable by having green lower leaf Larsen is belonging to family Zingiberaceae, surface, upper leaf surface without or with very order Zingiberales. It was established by Mood few silvery markings, inflorescences with 3–5 and Larsen (1997) based on C. aurantiflora flowers with bracteoles and glabrous corolla Mood & K.

This type species for published a preliminary checklist of 15 genera Cornukaempferia is undoubtedly a rare species of Zingiberaceae such as Alpinia L., Amomum and is endemic to northern and northeastern Roxb., Caulokaempferia K.

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Callus and suspension cells culture of Kaempferia parviflora was successfully established. Meris- tematic shoots can be used for utilization of plant cell biosynthetic capabilities for obtaining useful products from valuable medicinal plant to meet out the pharmaceutical demand and also for studying the metabolism. The medium containing combination of 0.2 mg/L 2,4-dichlorophenoxya- cetic acid (2,4-D) and 0.2 mg/L napthyleneacetic acid (NAA) promoted the highest callus induction at 20%. Transferring the initiated callus on the medium with 1 mg/L 2,4-D enhanced the prolif- eration rate up to maximum fresh weight of 6.71 gm. Growth curve of cultured cells revealed that the cells continued to grow until 50 days of culture and showed the highest peak (fresh weight) at 40 days in all different initial weight tested ( 0.2, 0.5 and 1.0 gram).

PhytoKeys 75: 31–55. doi: 10.3897/phytokeys.75.9837 Abstract A new genus from Borneo, Borneocola Y.Y.Sam, is described here. The genus currently contains eight spe- cies previously classified as members of the Scaphochlamys Baker. The finding is based on the results of the morphological and molecular studies of Scaphochlamys throughout its geographical range and its closely allied sister groups, Distichochlamys M.F.Newman and Myxochlamys A.Takano & Nagam. Borneocola is nested within the tribe Zingibereae and its monophyly is strongly supported by both ITS and matK se- quence data. The genus is characterised by several thin, translucent and marcescent floral bracts, absence of coloured streaks on the labellum and capitate stigma with two dorsal knobs.

  • Phylogeny of Hedychium and Related Genera (Zingiberaceae)Basedonits Sequence Data
    EDINB. J. BOT. 57 (2): 261–270 (2000) 261 PHYLOGENY OF HEDYCHIUM AND RELATED GENERA (ZINGIBERACEAE)BASEDONITS SEQUENCE DATA T. H. WOOD*, W. M. WHITTEN† & N. H. WILLIAMS‡ The phylogeny of Hedychium J. Koenig was estimated using sequence data of internal transcribed spacer regions 1 and 2 (ITS1, ITS2) and 5.8S nuclear ribosomal DNA. Sequences were determined for 29 taxa, one interspecific hybrid of Hedychium and one species in each of 16 other genera of Zingiberaceae representing tribes Hedychieae, Globbeae, Zingibereae and Alpinieae. Cladistic analysis of these data strongly supports the monophyly of Hedychium, but relationships to other genera are poorly supported. Within Hedychium, four major clades are moderately supported. These clades are also distinguishable on the basis of number of flowers per bract and distribution. Stahlianthus, Curcuma, and Hitchenia also form a strongly supported clade. Based on this limited sample, the currently defined tribes of Zingiberoideae are not monophyletic. The Asiatic genera form a monophyletic group within this broadly defined Hedychieae. The taxonomy and biogeography of Hedychium are reviewed. Keywords. Biogeography, ginger, Hedychium, ITS, phylogeny, Zingiberaceae. INTRODUCTION Within the Zingiberaceae four tribes are currently accepted (Smith, 1981): Globbeae (bow-shaped filament with unilocular ovary with parietal placentation; four genera); Zingibereae (pointed anther crest surrounding the style and staminodal lobes adnate to the labellum; one genus, Zingiber); Hedychieae (plane of leaf distichy parallel to the rhizome, lateral staminodes petaloid and free from the lip except in Siphonochilus and Curcumorpha, ovary trilocular with axile placentation or unilocular with basal or free columnar placentation; 21 genera); and Alpinieae (distichy of leaves perpen- dicular to the rhizome, lateral staminodes reduced to teeth or swellings or absent, ovary trilocular with axile placentation; 22 genera).

  • Callus Induction and Plant Regeneration from Leaf Explant of Cornukaempferia Aurantiflora Mood & Larsen
    Pak. J. Bot., 43(5): 2415-2418, 2011. CALLUS INDUCTION AND PLANT REGENERATION FROM LEAF EXPLANT OF CORNUKAEMPFERIA AURANTIFLORA MOOD & LARSEN PIYAPORN SAENSOUK Department of Biology, Faculty of Science, Mahasarakham University, Khamriang, Kantarawichai, 41150, Thailand. Abstract Young leaves of Cornukaempferia aurantiflora Mood & Larsen were used for the initiation of callus growth on Murashige Skoog medium supplemented with 3% sucrose and various concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D) in the light. The highest number of callus forming, percentage of callus formation and average weight of callus were obtained from young leaves cultured on the medium supplemented with 2.0 mg/l 2,4-D. Shoots were successfully regenerated on the medium with concentrations of 2,4-D and BA added. Introduction Materials and Method The genus Cornukaempferia is the new genus in Young leaves of C. aurantiflora (Fig. 1) were Zingiberaceae family from Thailand, described by Mood collected from natural habitats, then washed with running & Larsen (1997, 1999). Three species, C. aurantiflora, C. tap water, rinsed with 70% (v/v) ethyl alcohol for 30 longipetiolata and C. larsenii (Saensouk et al., 2007a) seconds, sterilized with 0.9% sodium hypochlorite have been recognized. This genus is listed as rare and it is containing 2 drops of Tween 20 for 15 seconds, followed endemic to Thailand. Its distribution is restricted to only by three washes with sterilized distilled water. The young few provinces in the northeastern and northern parts of the leaves were cut into 1x1 cm2 pieces and cultured on MS country. C. aurantiflora has been used by local people in medium (Murashige & Skoog, 1962) supplemented with northeastern Thailand to treat infected hemorrhoids and 3% sucrose, 0.7% agar and 0, 0.1, 0.5, 1, 2 and 4 mg/l 2,4- laryngitis which is common in Thai children.
