Zingiberaceae, with 53 genera and 1,377 species (Kong et al. 2010) is widely
distributed in tropical areas. Amomum Roxb., the second largest genus of the family with ca. 150 species
has its distribution along tropical Asia to Australia (Mabberley
2008). In India, the members of the
genus are mainly restricted to northeastern India, peninsular India, and the
Andaman & Nicobar Islands (Thomas & Sabu
2012). Hooker (1894) listed 48 species
in the Flora of British India. Thomas et
al. (2010) reported ca. 22 species from India.
Sabu (2006) reported six species for southern
India. Recent exploration by V.P. Thomas
(2009–2018), M. Sabu (1990–2018) and V.S. Hareesh VS (2013–2018) has added 11 species and one variety
to Indian flora, which takes the total count to 33 species and one variety of Amomum in India.
During a recent floristic
exploration along the Western Ghats of Karnataka, the first author collected
specimens belonging to the genus Amomum Roxb. After critical
study and scrutiny of literature and herbarium materials, the collected
specimen was identified as Amomum aculeatum. The species was first described by Roxburgh
in 1810 from the Malay Archipelago.
Later, Kurz collected the species in 1866 from
the South Andaman Islands during his voyages to Southeast Asia. In recent times N.G. Nair recollected the
species in 1976 from the South Andaman Islands and N. Bhargava
from the Little Andaman Islands (Balakrishnan &
Nair 1979; Pandey & Diwakar
2008). Hence, the present collection of
the species from Pushpagiri Wildlife Sanctuary, Kodagu, Karnataka (12.6330N & 75.6540E);
stands as a new record of this species in the wild for mainland India (southern
Western Ghats) (Fig. 1). A brief
description and photographs along with distribution are provided here.

and harvest honey from their hives without protective apparels, while the bees
remain docile.
