Cambridge revives 200-year-old botany pedagogy rooted in colonial-era science, obscuring Indigenous knowledge and modern ecological crises

Indigenous botanical knowledge systems—such as the Māori concept of *kaitiakitanga* (guardianship) or the Andean practice of *chakra* agriculture—frame plants as kin with reciprocal relationships to humans and ecosystems. These systems prioritize ecological balance over taxonomic classification, yet are systematically excluded from Western scientific narratives like Henslow’s. Modern botany’s focus on rare specimens for institutional archives mirrors colonial herbarium practices that severed plants from their cultural and ecological contexts.

The Henslow-Darwin lineage exemplifies how 19th-century botany served colonial expansion by classifying plants as resources for exploitation rather than sacred or communal entities. This era saw the violent displacement of Indigenous peoples to establish botanical gardens and herbaria, a pattern repeated globally (e.g., Kew Gardens’ colonial plant thefts). The rediscovery of these materials today reflects a broader nostalgia for 'pure' science, ignoring how such institutions were complicit in ecological and cultural genocide.

Non-Western botanical traditions often treat plants as active participants in knowledge systems, not passive objects of study. For example, the African concept of *ubuntu* ('I am because we are') extends to plants as interconnected beings, contrasting with the Cartesian dualism underpinning Henslow’s taxonomy. Similarly, the Chinese *shen nong ben cao jing* (Divine Farmer’s Materia Medica) classifies plants by therapeutic relationships rather than rigid hierarchies, offering a model for integrative medicine.

Modern botany has evolved beyond Henslow’s morphological focus to incorporate genetic, ecological, and Indigenous knowledge systems, as seen in projects like the *Flora of North America* or the *Global Biodiversity Information Facility*. However, the rediscovery of these archival materials risks reinforcing a romanticized view of science that ignores contemporary critiques of taxonomic bias and specimen colonialism. The inclusion of historical materials in teaching should be paired with decolonial frameworks to avoid perpetuating extractive practices.

Artistic and spiritual traditions often depict plants as living symbols of cosmic order, such as the Hindu *kalpavriksha* (wish-fulfilling tree) or the Celtic *crann Bethadh* (world tree). These perspectives frame botanical study as a sacred act of reciprocity, contrasting with the detached observation central to Henslow’s pedagogy. Contemporary artists like botanical illustrator Alice Pattullo blend scientific and Indigenous motifs to challenge Eurocentric plant representation, offering a creative counter-narrative.

Future botany must integrate Indigenous knowledge, citizen science, and digital tools to address biodiversity loss, as seen in initiatives like the *Indigenous Peoples’ Biocultural Climate Change Assessment Initiative*. Scenario modeling shows that decolonial approaches to plant science could triple conservation success rates by centering community stewardship. The revival of Henslow’s materials without structural reform risks entrenching the same extractive paradigms that drive current ecological collapse.

Marginalized botanists—particularly Indigenous, Black, and Global South scientists—have long critiqued the exclusionary practices of Western botany, yet their work is rarely centered in institutional narratives. Figures like Robin Wall Kimmerer (Potawatomi botanist) or Vandana Shiva (eco-feminist) highlight how plant knowledge is gendered and racialized in scientific discourse. The Cambridge course’s revival of Henslow’s materials without amplifying these voices perpetuates a cycle of epistemic injustice.
