This essay is the second in a three-part analytical series examining how indigenous plant knowledge in the Cape Floristic Region has been interpreted, asserted, and governed, and how claims acquire authority when the evidentiary record is incomplete.
Once it is accepted that the historical record of indigenous plant use in the Cape Floristic Region is fragmented, a further issue emerges. The question is not only what can be established from that record, but how claims are produced, circulated, and stabilised in its absence.
Claims about past plant use move across academic literature, regulatory documentation, commercial narratives, and public discourse. They do not do so evenly. Some are supported by multiple independent sources, including written records, archaeological indicators, and continuity within living communities. Others rely on isolated references or indirect inference. Some are plausible but cannot be verified under present conditions. Others persist despite being inconsistent with available evidence.
In the practice, these distinctions are difficult to sustain once claims begin to circulate.
A statement that appears tentatively in one context may be repeated without qualification in another. Over time, the conditions under which it was first articulated become harder to trace. Uncertainty is compressed out of the narrative. What remains is a simplified claim that appears settled, even when its evidentiary basis is narrow.
This process is shaped by institutional structures.
Access to publication, disciplinary convention, and proximity to regulatory or commercial platforms influence which claims are amplified and which remain peripheral. In the Cape Floristic Region, these dynamics intersect with longer histories of exclusion. Written records produced by early European observers are often treated as more reliable than oral testimony or contemporary community accounts. Absence from the archive is frequently interpreted as absence of practice, despite the historical circumstances that produced that absence.
These assumptions are rarely articulated directly. They nonetheless shape how knowledge is evaluated
They influence which research questions are pursued and which are set aside. They informregulatory interpretation. They affect how claims are framed for commercial use. Over time, they contribute to a knowledge environment in which certain narratives appear self-evident and others struggle to gain recognition.
Alongside this inherited hierarchy operates a different pressure. In response to historical erasure, uncertainty is sometimes resolved through assertion. Practices that are plausible are presented as established tradition. Continuity is assumed where disruption has been extensive. In commercial contexts, such moves are often framed as recognition or restitution. The result can be the consolidation of narratives that exceed what the evidence can support and that are difficult to revise once established.
For institutions engaged in research or application, the issue is not intention but responsibility.
Authority is exercised whenever a claim is made. Decisions about what to state, how to qualify it, and what uncertainty to carry forward shape how knowledge is received and reused. These decisions influence downstream activity, including product development, regulatory assessment, and benefit-sharing processes.
Claims made in research contexts do not remain confined to those settings. They are summarised, translated, and repurposed across domains. Nuance is often lost in the process. Institutions that generate or amplify claims therefore carry responsibility not only for their initial articulation, but for the ways those claims are likely to travel.
In the Cape Floristic Region, the consequences of this travel are tangible.
Claims about past use inform decisions about recognition, attribution, and benefit. They shape which communities are consulted and which histories are foregrounded. Inaccurate or overstated claims can misdirect these processes as effectively as silence, particularly when they establish narratives that later prove difficult to correct.
Legitimacy in this field is not established through certainty but through discipline.
This includes clarity about evidentiary thresholds and consistency in how they are applied. It includes transparency about limits and an explicit accounting of uncertainty. It also includes the willingness to refrain from assertion where the record cannot support it, even when doing so constrains narrative or commercial opportunity.
The archive does not determine what counts as knowledge on its own. Institutions do, through the claims they advance and the standards they apply. Making those standards visible does not resolve the tensions inherent in working with fragmented histories. It does make them explicit, and therefore subject to governance.
