Abstract:
Five species of genus Amorphophallus (Araceae) are recorded from Bangladesh, namely Amorphophallus bulbifer (Roxb.) Bl., A. longituberosus (Engl.) Engl. & Gehrm., A. margaritifer (Roxb.) Kunth, A. napalensis (Wall.) Bogn. & Mayo, and A. paeoniifolius (Dennst.) Nicholson. Among of the five species, A. margaritifer was first collected from Dhaka in 1893 by Sir J.D. Hooker (Siddiqui et al. 2007). The species seems to be rare in Bangladesh and recommendations for immediate identification of the habitat preference is needed for undertaking ex-situ and in-situ conservation measures (Siddiqui et al. 2007). This paper reports the rediscovery of A. margaritifer after more than 120 years from Bangladesh.
