Department of Botany offers free consultancy and plant identification under Botanical Information Service (BIS), as a part of the extension activity of the College.  It provides herbarium consultation, flowering plant identification, fodder/forage/weed identification including grasses & sedges and general information on plants free of charge to the general public and to government departments and ecological consultancies. The voucher specimens from individuals/institutions are received as gifts and they are deposited in the Herbarium of Sree Narayana College Kollam (SNCH) instead of fees for consultation.

Officer-In-charge: Dr Kiranraj MS, Assistant Professor in Botany

Name: Barringtonia asiatica (L.) Kurz  ‘Fish poison tree‘

Family: LECYTHIDACEAE

Notes:  This interesting tree was planted at Botanical Garden of Sree Narayana College, Kollam (BGSNCK) in1978, from the live collection of Andaman & Nicobar Islands. All parts of this species are poisonous, due to the presence of saponins. Its characteristic ‘box’ fruits are potent enough to be used as a fish poison. The seeds are ground to a powder and used to stun or kill fish for easy capture, suffocating the fish while the flesh is unaffected. The tree is considered a ‘flag species ‘of BGSNCK.
