Background Several medicinal properties have been reported for plants in the genus Evolvulus, such as a brain tonic and antifungal from Evolvulus alsinoides, and a sedative and an anthelmintic from Evolvulus nummularius. Therefore, the correct identification of the source plants is critically important. The aim of this research was to investigate t...

Recent cluster analysis suggests that the genus Hackelochloa Kuntze (Poaceae) should not be included in the genus Mnesithea s.l. It is thus an appropriate time to revise the genus Mnesithea found in Thailand for the ongoing Flora of Thailand project. The genus is represented in Thailand by seven species (one with two varieties) including M. striata...

Bananas in Thailand have been surveyed by our team to be at least 140 cultivars in the plantations, 10 wild species and, 4 introduced species. To characterize the genetic relationship of species and cultivars, a set of novel SSR markers was developed. Totaling 53 clones containing SSR motifs were isolated from SSR-enriched library of wild Musa balb...

To fulfil scarce and incomplete information on floral micromorphology of ensets (Ensete Bruce ex Horan.) in the banana family (Musaceae), a comparative anatomical study of two species: E. glaucum (Roxb.) Cheesman and E. superbum (Roxb.) Cheesman, native to Thailand was conducted. It was found that, apart from five fertile stamens presented in other...

Abstract— A new species of banana (Musaceae), Musa nanensis Swangpol & Traiperm, from Nan, Thailand, is described and illustrated. Based on vegetative features, M. nanensis could be superficially categorized as related to M. laterita; however, it possesses several unique floral characters from the rest of the genus Musa, especially its six tepals a...

Food plants used by Hmong from six villages in Mae Rim district, Chiang Mai province, Thailand, were studied during March 2012 to February 2013. Eight informants were interviewed individually in the fi eld and information was verifi ed for three times. One hundred and thirty species documented belongs to 58 families and 105 genera. Two threatened p...

Occurrence of multiple male buds in banana is a rare phenomenon. It is caused by branching of the peduncle or differentiation of the male flower into male bud. Five types of peduncle branching occur, viz.: (i) inside the pseudostem, (ii) at the time the peduncle emerges from the pseudostem, (iii) after the peduncle emerges from the pseudostem but b...

Musa serpentina Swangpol & Somana, a new species from Thailand in areas bordering Myanmar is described and illustrated. A key is given to the wild bananas of the area.

Banana sap has some special properties relating to various phenomena such as browning of fruits after harvesting, permanent staining of cloth and fibers, and antioxidant and antibleeding properties. Analysis of banana sap using high-performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS) indicated the presence of p...

A large amount of banana genetic resource has been found in Thailand which is believed to be one of the centers of its origins. To assess genetic diversity and determine genetic relationships of edible bananas in Thailand, 110 accessions of banana species and cultivars collected from villages and natural locations were investigated. UPGMA clusterin...

Anthocyanins were isolated from male bracts of 10 wild species of bananas (Musa spp. and Ensete spp.) distributed in Thailand. Six major anthocyanin pigments were identified by high performance liquid chromatography (HPLC), mass spectrometry (MS), and tandem mass spectrometry (MS/MS). They are delphinidin-3-rutinoside (m/z 611.2), cyanidin-3-rutino...

Single-copy chloroplast loci are used widely to infer phylogenetic relationship at different taxonomic levels among various groups of plants. To test the utility of chloroplast loci and to provide additional data applicable to hybrid evolution in Musa, we sequenced two introns, rpl16 and ndhA, and two intergenic spacers, psaA-ycf3 and petA-psbJ-psb...

Kan phai Mahidol (Afgekia mahidoliae B. L. Burtt & Chermsir.), the symbolic plants of Mahidol University, was named to commemorate the late Princess Mother, Somdej Phra Sri Nakarindra Boromarajajonnani (then Princess Srisangwan Mahidol). It is a rare tropical plant found in limestone mountains in the western side of Thailand. One among only three k...
