He left school early, mastered 2,000 plant names and now has species named after him

Pichan M Salim, a field parataxonomist from Kerala, has spent decades documenting the Western Ghats' plant diversity. With new species discoveries, rare plant records, conservation work, a President's award, and two species named after him, Salim's journey shows how field knowledge can transform modern science.Pichan M Salim, a field parataxonomist from Kerala, has spent decades documenting the Western Ghats’ plant diversity.

It is a classroom, a library and a living laboratory.The Wayanad-based field parataxonomist has spent decades identifying, documenting and conserving plants of the Western Ghats. Without following the conventional route of advanced academic degrees, Salim has built a reputation among researchers through his extraordinary knowledge of plant species and their habitats.His work has contributed to new plant discoveries, rare geographical records, scientific publications and the preservation of native genetic diversity.FROM A TRAINING PROGRAMME TO A LIFE IN THE FORESTSalim’s journey began in 1997, when he was among 20 local youths selected for a parataxonomy training programme conducted by the MS Swaminathan Research Foundation in Wayanad.He joined MSSRF the following year and began working on agro-biodiversity conservation. Over time, he developed the ability to identify more than 2,000 botanical names and assisted researchers studying plants across the Western Ghats.MSSRF describes him as a field botanist who has systematically documented flowering plants in the region for more than two decades. An earlier MSSRF profile credited him with helping discover eight new species and recording several new plant records.More recent reporting has placed his contribution at 23 new plant species, more than 10 new geographical records and over 53 scientific publications.RECOGNISED BY THE PRESIDENTSalim received the Plant Genome Saviour Award for 2020-21, presented by President Droupadi Murmu in September 2023.For his many contributions, he has also received state-level recognition, including the Kerala State Biodiversity Board Award and the Vanamithra Award. (Photo: Facebook/@/salim.pichan.3) TWO PLANT SPECIES CARRY HIS NAMESalim’s contribution has also been recognised in botanical nomenclature.The orchid Seidenfadeniella salimii, first described from Kerala’s Western Ghats, was named in his honour. The original scientific paper acknowledged Salim for collecting specimens and contributing to plant taxonomy. The species is now treated in Kew’s Plants of the World Online under the accepted name Cleisostomopsis salimii.Another species, Impatiens salimii, is also named after him and is accepted as a plant native to Kerala, according to Kew records.For Salim, these names are not merely personal recognition. They represent the role of field knowledge in helping scientists understand biodiversity that may otherwise remain undocumented.THE PLANT THAT RETURNED AFTER 175 YEARSOne of Salim’s most notable recent contributions came through the rediscovery of Campbellia aurantiaca, a rare flowering parasitic plant that had not been credibly recorded for more than 175 years.The plant was found in the Thollayiram region of Wayanad by a team involving Salim and researchers from India and Sri Lanka. It had originally been documented by Scottish botanist Robert Wight near Naduvattom in Tamil Nadu in 1849.For years, the plant’s identity had been confused with another species, Christisonia bicolor. The research team resolved the taxonomic confusion, and the findings were published in the Kew Bulletin in December 2025. MSSRF described the plant as a root parasite that depends entirely on a host plant for its nutritional needs.

The research, published in the journal Species, recorded the plant’s distinctive characteristics and explained its importance to the conservation of wild tuber diversity.HIS OWN GARDEN IS A LIVING GENE BANKSalim’s conservation work extends beyond forest surveys. At his homestead in Athimoola, Wayanad, he has developed an in-situ and ex-situ bio-conservatory.The collection reportedly includes 614 traditional and wild plant varieties, including wild ornamentals, wild relatives, rare and threatened species, and cultivated genetic diversity variants. Among them are plants such as Bulbophyllum aureum and Medinilla malabarica.His story is a reminder that scientific knowledge does not always begin in a laboratory or university. Sometimes, it grows through years of walking forest trails, listening to local communities and learning to recognise what others might overlook.- EndsPublished On: Sep 11, 2026 17:28 IST
