[Botany • 2010] Elettariopsis wandokthong • Elettariopsis Baker (Zingiberaceae) in Thailand－A New Species and A New Record

Elettariopsis wandokthong 

Picheans. &  Yupparach  

ABSTRACT
 Six taxa of Elettariopsis Baker (Zingiberaceae) were previously accounted for Thailand. In this paper, Elettariopsis wandokthong, a new species from Thailand, is described and illustrated. Also, the distribution of E. monophylla (Gagnep.) Loes. in Thailand is reported here for the first time with full description and illustration. Key to species currently enumerated for Thailand is also provided.

KEY WORDS: Zingiberaceae, Thailand, Elettariopsis wandokthong, new species, Elettariopsis monophylla, new record.

Diagnose: Elettariopsidi trilobae similis, foliis 2-4 lanceolatis ad oblongis vel ellipticis utrinque glabris, ligula 1-2 mm longa pubescenti, apice bilobo, calycis tubo corollae tubo longiore pubescenti, ovario pubescenti differt.

Distribution: This new species can only be found in the type location. However, it is widely cultivated in Thailand.

 Ecology: The new species grows under the shade of dried deciduous forest, at the altitude of 62-240 m.

 Vernacular names: Wan Dokthong (วานดอกทอง), Wan Maha Saneh (วานมหาเสนห),  彎斗松擬荳蔻 (Chinese new name).

 Ethnobotany: This new taxon is believed to process a magical power, and therefore, it is used as a good-luck charm. The Thai names imply magical seductive power. The plants are grew in pots, and put in front of shops believing that they will help attracting customers, especially when the plant is in bloom (usually as early as January to early May). The rhizomes of this taxon are also used as one of the ingredients for making “magical herbal charming oil” or “magical charming lip balm”, believing that after applying it to one’s body (oil) or lips (lip balm), it will help attracting the targeted opposite sex, particularly women.

[Botany • 2016] Caulokaempferia kayinensis & C. monensis • The Genus Caulokaempferia (Zingiberaceae) in Myanmar Part 1: Two New Species from South Myanmar

Two new species, Caulokaempferia kayinensis Picheans. & Sangnark and C. monensis Picheans. & Sangnark (Zingiberaceae), are described. This is the first report of the genus from Myanmar. The sessile inflorescence of C. kayinensis, hidden in the uppermost two leaf sheaths, is unique among the yellow-flowered group of the genus. The long ligule, ovate bract, and the bract-formation on inflorescence are characteristic of C. monensis. Full descriptions, together with ink line-drawings with water-color and photographic illustrations, of these new taxa are given.

ABSTRACT

A new species of Caulokaempferia K. Larsen (Zingiberaceae), Caulokaempferia pubescens Picheans. & Phokham, from Changwat Mae Hong Son in Northern Thailand is reported. Full descriptions, together with ink line–drawing with water color and photographic illustrations are given. Relationship of this new species with their phylogenetically closest related taxa, C. larsenii

Three New Species of the Yellow-flowered Caulokaempferia (Zingiberaceae) from Northeastern Thailand

Chayan Picheansoonthon and Supachai Koonterm

Abstract
Three new species of the genus Caulokaempferia (Zingiberaceae) from northeastern Thailand, C. phuwoaensis Picheans. & Koonterm, C. phulangkaensis Picheans., and C. phutokensis Picheans. are described and illustrated. Relationship with other closely related taxa is also discussed.

Keywords: Zingiberaceae, new Caulokaempferia, Northeastern Thailand.

• ว่านเปราะต้น เปราะต้นภูวัว

Caulokaempferia phuwoaensis Picheans. & Koonterm

Distribution: This new species can be found at Tham Noi (ถ้ำน้อย) and Jet Si Waterfall (น้ำตกเจ็ดสี) in Phu Woa Wildlife Sanctuary, Amphoe Bung Khla,Changwat Nong Khai in Northeastern Thailand.

Ecology: This new species grows on moist sandstone rocks near the waterfall under the shade of mixed deciduous forests, at the altitude of 203-325 m. It is one of the dominant species of the special type of seasonal wetland vegetation called “blanket marsh vegetation” only appearing in the rainy season.

Vernacular names: Wan Proa Ton (ว่านเปราะต้น), Proa Ton Phu Woa (เปราะต้นภูวัว)

Use: Medicinal.

Note: This new species is similar to C. jirawongsei Picheans. & Mokkamul, but can be easily distinguished by its shorter ligules (2-5 mm), fewer lanceolate-ovate to ovate leaves (3-5), broadly ovate bract(s), and 6-7(-10)-flowered lowest bract. Also, this new taxon is terrestrial and smaller in habit. Leaves of C. phuwoaensis Picheans. & Koonterm are thicker in texture, and generally arranged on the upper half of apseudostem.

• ว่านเปราะหิน เปราะหินภูลังกา เปราะต้นภูลังกา

Caulokaempferia phulangkaensis Picheans.

Distribution: This new species can be found in TadKham Waterfall (น้ำตกตาดขาม), Phu Langka National Park, Amphoe Ban Phaeng, Changwat Nakhon Panomin Northeastern Thailand.

Ecology: Moist red sandstone rocks along the waterfall, under the shade of mixed deciduous forests at the altitude of 176-195 m.

Vernacular names: Wan Proa Hin (ว่านเปราะหิน), Proa Hin Phu Langka (เปราะหินภูลังกา), Proa Ton PhuLangka (เปราะต้นภูลังกา)

Use: Medicinal.

Note: This new species is similar to C. jirawongsei Picheans. & Mokkamul, but can be easily distinguishedby its shorter ligules (2-5 mm), more leaves (7-10), andfewer bracts (1-2, rarely 3). It can be differentiated from C. phuwoaensis Picheans. & Koonterm by itsepilithic habit, more lanceolate leaves arranged along apseudostem, and fewer elliptic-ovate bracts. The labellum of this new species is unique, comparing with other taxa mentioned in this paper, in the long ligulate median lobe with apex divided halfway down and apex of each lobe acute.

• ว่านเปราะหิน เปราะหินภูทอก

Caulokaempferia phutokensis Picheans.

Distribution: This new species can be found in PhuTok Noi (ภูทอกน้อย), Amphoe Si Wilai, Changwat Nong Khai in Northeastern Thailand.

Ecology: Moist red sandstone rocks under theshade of mixed deciduous forests, at the altitude of 270-350 m.

Vernacular names: Wan Proa Hin (ว่านเปราะหิน), Proa Hin Phu Tok (เปราะหินภูทอก)

Use: Medicinal

Note: This new species is morphologically similar to C. jirawongsei Picheans. & Mokkamul, but can be easily distinguished by its large ovate leaves and a characteristic bract arrangement. In flowering stage, the bracts of this new taxon wraped tightly around an inflorescence axis, until later fruiting stage. Also, the“flowers” of this new species is very delicate, and will be shrunk within 2-3 hours after bloom.
