Reappraisal of sectional taxonomy in Musa (Musaceae)

The present work is part of a continuing study on Musa taxa by the author. Several molecular analyses support accep- tance of only two Musa sections, M. sect. Musa and M. sect. Callimusa. Musa sect. Rhodochlamys is synonymized with M. sect. Musa and M. sect. Australimusa and M. sect. Ingentimusa are treated as synonyms of M. sect. Callimusa. Species lists are provided for the two accepted sections.

Musa chunii Häkkinen, a new species (Musaceae) from Yunnan, China and taxonomic identity of Musa rubra.

The center of diversity of the genus Musa (Musaceae) is in Southeast Asia, a region not studied in detail and where new species and varieties continue to be reported. A new wild banana species, M. chunii Häkkinen from Yunnan, China is described and illustrated based on observed morphological characteristics in the field. This extremely rare new species was only found in Tongbiguan Nature Reserve, Dehong District, West Yunnan. A key to M. chunii and related taxa is provided. In addition, critical notes regarding M. rubra Kurz identity are given.

A new species of the wild banana genus, Musa (Musaceae), from Borneo

Abstract A new species of wild banana, Musa bauensis Häkkinen & Meekiong, is described and illustrated. It is from the Bau limestone area, Sarawak, East Malaysia.

Typification and check-list of Ensete Horan. names (Musaceae) with nomenclatural notes

ABSTRACT All the names accepted in the genus Ensete Horan. are listed and typifications supplemented. All Ensete names have originally been described as belonging to the genus Musa L. Altogether, 37 names were found, the fossil Ensete oregonense excluded, 36 species and variety are considered. Currently, eight species are recognised, i.e. E. agharkarii, E. gilletii, E. glaucum, E. holstii, E. homblei, E. perrieri, E. superbum and E. ventricosum, and one variety, E. glaucum var. wilsonii comb. nov. Of the names, eight are illegitimate, and three dubious. A great confusion seems to be connected with E. ventricosum, which is indigenous in Africa. We consider that 14 names are synonymous with it. As herbarium specimens of type material are often of bad quality and sometimes completely undiscovered or perhaps lost completely, some typification is based on the drawings. In this article, nine Musa names, currently included in Ensete, are lectotypified.

Typification of Musa mannii, M. sanguinea and M. x kewensis (Musaceae)

SummaryIn 1949 a single plant of Musa mannii Baker, grown in Trinidad from seeds imported from Java, was incorrectly identified as Musa sanguinea Hook. f. As a consequence, the circumscription of M. mannii became confused. M. mannii is very rare or extinct in its indigenous area in Assam, India. However, it is grown in many botanic gardens worldwide. In contrast, M. sanguinea is a common sympatric species with M. aurantiaca in upper Assam and Arunachal Pradesh, India, but it is today unknown to most botanists. The aim of this study is to settle the true identity of M. mannii and M. sanguinea. The names are typified, as well as Musa × kewensis Baker (M. mannii × ornata).
