Abstract
The paper deals with four taxa of the family Araceae as new records for Bangladesh, namely, Aglaonema commutatum Schott, A. marantifolium Blume, Colocasia mannii Hook. f. and Remusatia vivipara (Roxb.) Schott. An up-dated nomenclature, important synonyms, illustrated description, flowering and fruiting times, specimen citation, ecology and geographical distribution for each species have also been given. Key words Four new records, Araceae, Bangladesh DOI: 10.3329/bjpt.v12i2.601 Bangladesh J. Plant Taxon. 12(2): 39-48, 2005 (December)
Highlights
The family Araceae consists of 110 genera and 2500 species distributed mostly in the tropics and sub-tropics (Croat 1979)
During recent past extensive field trips made throughout the country have resulted in many new records of Araceae for Bangladesh (Ara 2000, 2001; Ara and Hassan 2003, 2005; Ara and Khatun 2002; Ara et al 1998, 2001, 2002, 2003 2004, 2005; Uddin et al 2001)
The paper is based on the materials collected from different parts of the country during field trips made from 2000-2005, which are preserved in the Bangladesh National Herbarium (DACB)
Summary
The family Araceae consists of 110 genera and 2500 species distributed mostly in the tropics and sub-tropics (Croat 1979). Prain (1903) and Hooker (1893) reported 27 and 30 species, respectively from the area that comprises Bangladesh. Prain (1903) and Hooker (1893) reported 27 and 30 species, respectively from the area that comprises Bangladesh. During recent past extensive field trips made throughout the country have resulted in many new records of Araceae for Bangladesh (Ara 2000, 2001; Ara and Hassan 2003, 2005; Ara and Khatun 2002; Ara et al 1998, 2001, 2002, 2003 2004, 2005; Uddin et al 2001). Some recent collections from Madhupur (Mymensingh), Sherpur, Netrokona, Maulvi Bazar and Bandarban districts include the following species of this family namely Aglaonema commutatum Schott, Aglaonema marantifolium Blume, Colocasia mannii Hook. F. and Remusatia vivipara ( Roxb.) Schott, that are new records for Bangladesh. The genus Remusatia Schott is a new generic record for Bangladesh. None of the above mentioned species is found in the work of previous workers who published on the flora of this region, viz., Hooker (1893), Prain (1903), Heinig (1925), Calder et al (1926), Sinclair (1955), Rao and Verma (1976), Huq and Khan (1984), Nicolson (1987), Karthikeyan et al (1989), Khan et al (1994), Noltie (1994), Mia and Khan (1995), Rahman and Uddin (1997), Uddin et al (1998), Uddin and Rahman (1999), Rashid et al (2000), Ara (2001), Khan and Huq (2001) and Rahman (2004a, 2004b)
