New Species of Cardamom in Kerala

Recent research has revealed findings regarding cardamom, often referred to as the ‘Queen of Spices’. An international team of researchers has identified six species closely related to the well-known green cardamom, Elettaria cardamomum. This discovery challenges previous assumptions that only one species existed in the genus Elettaria. The study, published in the journal Taxon, marks the importance of these findings for the future of spice production.

Background on Cardamom

• Cardamom is one of the most valuable spices globally, following saffron and vanilla.
• The spice is derived from the seed capsules of Elettaria cardamomum.
• The name ‘Elettaria’ is derived from the Malayalam term ‘elletari’, used in a 17th-century botanical text.
• Cardamom’s economic significance is immense, making it a key player in the spice market.

New Discoveries

• The research team, including experts from Denmark, Colombia, and other countries, has reclassified the genus Elettaria to include seven species.
• The newly identified species are Elettaria facifera and Elettaria tulipifera, both discovered in Kerala’s Western Ghats. Four species previously classified under the genus Alpinia have now been reassigned to Elettaria.

Characteristics of New Species

Elettaria facifera is notable for its sessile leaves and distinct flowering shoots. It has a white labellum with purple-red markings and is referred to as ‘Vai noki elam’ by the Mannan tribe due to its fruit’s resemblance to an open mouth. Elettaria tulipifera features a striking tulip-shaped inflorescence with large, vibrant bracts.

Significance of Findings

This research marks the potential of these newly identified species in enhancing spice production. The genetic diversity within the Elettaria genus could lead to improved cultivation practices and greater economic benefits. About these species better may also provide vital information about their morphological variations.

Conservation Efforts

The researchers emphasise the need for conservation initiatives. Both new species face threats from natural and human-induced factors. Protecting these plants is crucial for sustaining their populations and ensuring their availability for future generations.

Global Collaboration

The study involved collaboration among researchers from various countries. This international effort puts stress on the importance of global partnerships in biodiversity research. The findings contribute to a broader understanding of plant taxonomy and conservation strategies.

Future Research Directions

The discovery of these species opens avenues for further studies. Future research could focus on their ecological roles, potential uses in agriculture, and contributions to the spice industry. Enhanced understanding of these species may lead to innovations in cultivation and conservation practices.
