Cryptogamic Type Specimens of CAL: A Comprehensive Catalogue

The present paper provides detailed documentation and an updated inventory of cryptogamic type specimens (excluding Fungi) deposited in the Central National Herbarium (CAL), Botanical Survey of India, Howrah, West Bengal, India. As one of the oldest and most significant botanical repositories in South Asia, CAL houses a substantial collection of non-flowering plants that serve as critical nomenclatural references for Paleotropical and Oriental floristics. Our survey identified a total of 453 cryptogamic type specimens, comprising Algae (20), Bryophytes (66), Lichens (9), and Pteridophytes (358). Each entry was cross-referenced with protologues and original labels to verify its current nomenclatural status and typification category (e.g., holotype, paratype, isotype, or syntype). The collection includes historically significant materials from the 19th and 20th centuries, reflecting the intensive botanical explorations across Paleotropical and global regions. This cataloging effort aims to enhance the accessibility of these specimens for global taxonomic research and to provide a baseline for future revisionary studies and digitization initiatives. The data presented here underscore the pivotal role of the CAL herbarium in preserving the region's botanical heritage.

Introduction

The Central National Herbarium (CAL), located in Howrah, West Bengal, within the AJCB Indian Botanic Garden, is one of India’s oldest and most significant herbaria. Established in 1795, it is administered by the Botanical Survey of India (BSI) under the Ministry of Environment, Forest and Climate Change. CAL functions as the national repository for preserved plant specimens and plays a crucial role in taxonomic research and the documentation of India’s botanical diversity. The herbarium houses more than 3 million specimens, both of phanerogams and cryptogams, including numerous type specimens collected from across India and from various Paleotropical and global regions.

Type specimens are the fundamental reference points for botanical nomenclature; they are the physical records upon which the description of a new species is based. The authentication of taxa relies heavily on the accessibility of these "nomenclatural types," making their documentation a high priority for the scientific community (Haber 2012; Yang 2012; Mutanen et al., 2015; Prosser et al., 2016; Turland et al., 2018). Given that many original descriptions of Indian flora were published centuries ago, the preservation and cataloging of type specimens are essential for resolving taxonomic ambiguities.

While phanerogamic (flowering plant) collections are often well-documented, the cryptogamic wealth—comprising algae, lichens, bryophytes, and pteridophytes—represents a significant yet often understudied portion of India’s biodiversity. The diversity of non-flowering plants preserved at CAL reflects the varied bioclimatic zones of the Indian subcontinent, from the Himalayan peaks to the tropical coasts. All specimens are maintained with special care and maintenance techniques for each group of cryptogamic specimens present at CAL, and Type specimens are prioritized and kept separately in distinct boxes/Pigeons/rooms for enhanced safety and restricted access (Fig. 1-3).

It provides essential support for research in plant taxonomy, ecology, biodiversity conservation, and ethnobotany. In addition, CAL maintains a reference library and a digital herbarium database, offering an important resource for researchers, students, and environmentalists from India and abroad. The present study was undertaken to comprehensively document the Cryptogamic TYPE specimens (excluding Fungi) preserved in CAL. It is hoped that this work will serve as a useful tool in the hands of all cryptogam lovers and researchers to promote understanding of plant species.

Methodology

The present study involved a comprehensive screening of the cryptogamic collections (excluding Fungi) preserved at the Central National Herbarium (CAL) to identify and document all primary and secondary type specimens. Each identified specimen was physically verified against its original herbarium label and cross-referenced with protologues and taxonomic literature to confirm its current nomenclatural status and typification category. The specimens were then organized by major group (Algae, Bryophytes, Lichens, and Pteridophytes), with scientific names updated in accordance with the latest botanical literature. Finally, a detailed inventory was compiled, including current scientific names, collection data, and original citations to enhance global accessibility for taxonomic research.

Results Discussion

The systematic survey of the cryptogamic collections at the Central National Herbarium (CAL) identified a total of 453 type specimens distributed across four major taxonomic groups. The collection is predominantly Pteridophytes, with 358 types (approx. 79% of the total) distributed across 261 taxa in 19 families. This is followed by Bryophytes, which comprise 66 types (14.6%) distributed across 51 taxa under 7 families. Algae are represented by 20 types (4.4%), encompassing 13 taxa across 9 families, while Lichens account for 9 types (2%), comprising 9 taxa across 7 families (Fig. 5-9). These specimens encompass a broad range of nomenclatural categories, including holotypes, isotypes, syntypes, and paratypes, primarily originating from 19th and 20th-century botanical explorations across various Paleotropical and global regions. The distribution of specimens from various states in India is shown on the map (Fig. 4). While the majority of the collection originates from intensive botanical explorations of the Indian subcontinent (including Nepal, Sri Lanka, and Bhutan), the data reveal a significant international representation. A substantial number of type specimens, particularly Pteridophytes, hail from China, followed by Southeast Asian nations such as Malaysia and the Philippines. Furthermore, the repository houses historically significant materials from diverse global regions, including Mexico, Hawaii, Fiji, and Zimbabwe (Fig. 10, 11).

The presence of specimens from such varied bioclimatic zones, ranging from the Himalayas to the Pacific Islands and African savannas, underscores the pivotal role of CAL as a premier global repository. This updated inventory provides a verified baseline for international taxonomic research and highlights the herbarium's enduring legacy in preserving the botanical heritage of both the Paleotropical and global floristics. Such documentation is essential for resolving taxonomic ambiguities and ensuring that these critical nomenclatural references remain accessible for modern revisionary studies and digitization initiatives.

Conclusion

This systematic survey underscores the exceptional scientific and historical significance of the cryptogamic collections housed at the Central National Herbarium (CAL). By documenting 453 type specimens, it reveals a striking predominance of Pteridophyte types (79%), while also establishing a verified inventory for type specimens of Bryophytes, Algae, and Lichens. Far from being a regional repository, CAL emerges as a global center of biodiversity, safeguarding critical 19th and 20^th century materials that span the Indian subcontinent, China, Southeast Asia, and the Pacific. This updated record provides a vital baseline for resolving taxonomic ambiguities and lays the foundation for future digitization and revisionary studies. Ultimately, these findings reaffirm CAL’s stature as a premier institution dedicated to preserving the botanical heritage of the Paleotropical world—and extending its relevance well beyond.
