A new species, Zingiber procumbens Nob.Tanaka & M.M.Aung (Zingiberaceae), from Kayah State, eastern Myanmar, is described with color plates. Zingiber procumbens is assignable to section Cryptanthium Horan. based on lateral inflorescences on the procumbent peduncles. This species is similar to Z. bradleyanum Craib in vegetative characters, but well distinguished from it by a combination of long bilobed ligules, lamina with silvery line, procumbent peduncle, tubular bracts with dark reddish stripes, and flowers with purple orbicular labellum. Detailed descriptions, color plates and preliminary IUCN assessments are provided.

Balaenopterid whale specimens preserved in several institutions totaling 19 were examined. Specimens identified to species level were 14, i.e. 3 Balaenoptera musculus, 6 B. edeni, and 5 B. omurai. The remaining 5 specimens were not identified. The existence of B. omurai from Myanmar waters was confirmed based on the morphological characters of the skull and the first rib. This article is the first confirmation of this species in Myanmar. Among the two already “confirmed” species, B. musculus was identified by Smith et al. (1997) based on the actual specimen in the Natural History Museum, however for B. edeni, the specimens we examined were not observed for species identification and no preceding work reported the existence of B. edeni, except for the type specimen collected in Mon state in 1871 and now preserved in the Indian Museum, Kolkata (Anderson, 1879).

A new orchid species, Dendrobium popaense T.Yukawa & Nob.Tanaka is described from Mt. Popa, central Myanmar. It is discriminated from the closely related D. bensoniae by its smaller size in perianth lobes, its higher ratio of the length of mentum to dorsal sepal, and its conspicuously papillate operculum. From D. jinghuanum, the new species is separable by its lack of purple floral pigmentation, its lemon-yellow disk of labellum, its smaller size in perianth lobes, its higher ratio of the length of mentum to dorsal sepal, and its short, erect stem.

To clarify biogeographic patterns of two mushroom species (Phallus merulinus and Geastrum courtecuissei) previously reported from Myanmar, sequence data of the internal transcribed spacer (ITS) region of nuclear ribosomal DNA were retrieved from GenBank. The BLAST search and phylogenetic analyses of Phallus indicated that P. merulinus and P. atrovolvatus from wide areas, including Australia, Myanmar, Thailand, Brazil, and French Guiana, cannot be distinguished molecularly. The species was, therefore, considered widespread across tropical to subtropical regions. In contrast, G. courtecuissei from Myanmar was tightly clustered exclusively with G. courtecuissei from Central and South America, supporting the idea of its disjunct distribution between Southeast Asia (Myanmar) and Central-South Americas.
