The flora of Tropical Asia is among the richest in the world, yet the actual diversity is estimated to be much higher than previously reported. Myanmar and Thailand are adjacent countries that together occupy more than the half the area of continental Tropical Asia. This geographic area is diverse ecologically, ranging from cool-temperate to tropical climates, and includes from coast, rainforests and high mountain elevations. An updated checklist of aquatic plants, which includes 78 species in 44 genera from 24 families, are presented based on floristic works. This number includes seven species, that have never been listed in the previous floras and checklists. The species (excluding non-indigenous taxa) were categorized by five geographic groups with the exception of to reflect the rich diversity of the countries' floras.

 Aquatic plants flora Myanmar Thailand Grant-in-Aids from The Scandinavia Japan Sasakawa Foundation to Y.I. Introduction

Myanmar and Thailand, adjacent countries, comprise more than half of the tropical region for continental Asia. Situated within the Indo-Myanmar (Burma) hot-spot, this area is among the richest in biodiversity in the World (Van Dijk et al. 2004), with the estimated biodiversity being much higher than has been previously reported. The area is geographically diverse, going from cool-temperate to tropical and from the coast to rainforests to high mountains (Kress et al. 2003).

The aquatic floras of Myanmar and Thailand have been separately investigated. The Flora of Thailand project was launched in the 70’s, led by European and Thai herbaria and institutions. The aquatic species were treated in separated volumes (Table 1). The aquatic flora of Myanmar has not been published yet, although many of the species investigated are listed in the aquatic flora of India (Cook 1996).

 Materials and methods

The aquatic plant specimens treated in this study come from field works carried out in 2006 (Myanmar), 2008 (Myanmar), and 2012 (Thailand). Plants were hand-collected from aquatic environments e.g. ponds and lakes. Occasionally collections were made by boat (Fig. 1). In addition to field collections, exhaustive herbarium surveys were conducted in major herbaria, including AAU (Denmark), BFK (Thailand), GH (USA), MBK (Japan), TI (Japan), and TNS (Japan). The herbarium specimens were morphologically identified by using Cook (1996) or the Flora of Thailand series (Table 1). For Potamogetonaceae, in addition to the above mentioned literature, Flora of China treatment was also referred (Guo et al. 2010); for Menyanthaceae, for which no volumes for the family has been published in the Flora of Thailand, Cook (1996), Ho and Ornduff (1995), and Tippery et al. (2009) were used for identification. The identified species were classified and ordered following Haston et al. (2009). Some specimens of species cited in previous floras were examined. Species distribution was obtained from regional floras. Where distribution data were absent or where the floras have not yet been published, question marks have been inserted, e.g., ?Myanmar.

 Distribution

Bangladesh, ?Cambodia, China, India (nationwide), ?Indonesia, Japan, ?Malaysia, Myanmar, Nepal, Papua New Guinea, Sri Lanka, ?Vietnam; Oceania; N. America; S. America.

 Analysis

The 78 species were classified into six geographic categories: Widespread; Eurasian cool-temperate; Asia – Australia; Tropical Asia; Pan-Tropics; invasive (Table 2). The data concerning the general distribution was taken Boyce (2012), Boyce et al. (2012), Chayamarit (2005), Cook (1996), Guo et al. (2010), Haynes (2001f), Haynes (2001d), Haynes (2001a), Haynes (2001e), Haynes (2001b), Haynes (2001c), Ho and Ornduff (1995), Ito (2013b), Ito et al. (2009), Landolt (2001), Simpson (2008), Larsen (2000), Tippery et al. (2009), Yamazaki (1990), Barkera and Jobson (2013).

 Discussion

Altogether, we identified 380 specimens, excluding 31 duplicates, belonging to 75 species of 41 genera from 23 plant families; the remaining 3 species belonging to 3 genera of 3 families were listed with no voucher specimens. Geographically the species distribution pattern can be classified into six categories: Widespread; Eurasian cool-temperate; Asia – Australia; Tropical Asia; Pan-Tropics; and Invasive.

Widespread

This category is mostly congruent with 'Widespread Species' of Sculthorpe (1967).

 Eurasian cool-temperate

The species clustered in this category are distributed mainly in cool-temperate region of Eurasia, thus limiting the distribution to a small portion of Southeast Asia (Myanmar: Shan state; Thailand: Northern states).

 Asia – Australia

The species included in this category have a distribution in either Australia or East Asia or both, e.g., Australia: Mimulus orbicularis and Nymphoides aurantiaca; East Asia: Acorus gramineus, Blyxa japonica, Limnophila sessiliflora, Potamogeton distinctus, Potamogeton maackianus, Potamogeton wrightii, and Sagittaria trifolia; Australia and East Asia: Blyxa aubertii, Blyxa echinosperma, Hydrocharis dubia, Limnophila indica, Monochoria vaginalis, Najas graminea, Ottelia alismoides, Persicaria attenuata subsp. pulchra, Potamogeton octandrus, Utricularia aurea, and Utricularia australis.

 Asian tropics

This category comprises the largest number of species for the aquatic floras of Myanmar and Thailand. Some of the species included are endemic or narrowly distributed e.g., Cryptocoryne is endemic to tropical Asia. The monotypic genus Nechamandra occurs predominantly in India but also scattered in other parts of tropical Asia (also reported from one locality of Africa). Another monotypic genus Barclaya is among the tropical Asian endemics. The genera Aponogeton (Aponogetonaceae), Blyxa, Najas, (Hydrocharitaceae), Myriophyllum (Haloragaceae), Nymphoides (Menyanthaceae), Monochoria (Pontederiaceae), Utricularia (Lentibulariaceae) have their center of diversity in tropical Asia.

On a species level, the distribution is further classified into three groups: 1) Indo-China, 2) Southeast Asian, and 3) endemic to Myanmar and Thailand. The first group includes Cryptocoryne crispatula, Eriocaulon setaceum, Limnophila heterophylla, Monochoria hastata, Myriophyllum tetrandrum, Myriophyllum tuberculatum, Najas indica, Najas graminea, Nechamandra alternifolia, Nymphaea nouchali, Nymphaea pubescens, Nymphoides hydrophylla, and Utricularia stellaris (also known from Africa). The second group includes Barclaya longifolia, Cryptocoryne albida, Cryptocoryne cordata, Monochoria elata, and Ottelia cordata. The last group includes Blyxa quadricostata, Crinum thaianum, Cryptocoryne cruddasiana, and Utricularia punctata.

 Pan-tropics

This category with eight species is mostly congruent with 'Pan-tropical Species' of Sculthorpe (1967).

 Invasive

The aquatic floras of Myanmar and Thailand have well known invasive aquatic species including Elodea densa (Hydrocharitaceae) and Eichhornia crassipes (Pontederiaceae).
