Musa azizii, a New Musa Species (Musaceae) from Northern Borneo

摘要

A new wild banana species, Musa azizii Hakkinen, is described and illustrated. The species is extremely rare, originating in the Lumut Range area of Sarawak, East Malaysia.Borneo has a large number of wild banana species, In 1902 an Italian botanist Dr. Odoardo Beccari was the first who described wild bananas from Borneo based on his studies in Sarawak during the period of 1865-68 (Beccari 1902). These descriptions were republished in Webbia (Martellil923). He described and named four species: Musa borneensis Becc., M. campestris Becc , M. hirta Becc. and M. microcarpa Becc. In 1967 Prof, Mitsuru Hotta described three new species, M. flavida M Hotta., M muluensis M. Hotta. and M. tuberculata M. Hotta based on his expeditions in Sabah Brunei and Northern Sarawakl 963-4 and mentioned "The number of the wild species of Musa in Borneo may count more that 10 or even 20, though only 5 species have been described up to present"(Hotta 1967). Simmonds, who never visited in Borneo, described M. beccarii Simmonds from a cultivated plant in Trinidad, which he grew from seeds imported from Sabah (Simmonds 1960) In 2000 Dr George Argent from Royal Botanical Garden, Edinburgh described M. monticola [Hotta ex] Argent and M. suratii Argent from Sabah (Argent2000). Then the author described five varieties of M campestris Becc., i.e., var., lawasensis Hakkinen, var. limbangensis Hakkinen, var. miriensis Hakkinen, var sabahensis Hakkinen, var. sarawakensis Hakkinen and gave notes for the var. campestris (Hakkinen 2003) Then the author described M. voonii Hakkinen (Hakkinen 2004) and M, bauensis Hakkinen & Meekiong (Hakkinen & Meekiong 2004). These author's descriptions are based on the expeditions in 2001, 2002 and 2004 in Borneo With the discovery of the newdescribed species M. azizii, the number of native Musa species in Borneo has increased to 15 excluding M. textilis Nee, which is an introduction in Borneo from the Philippines (Bishop & Curtler 1925, Marsh 1947).
