Observation Narrative
Floating stratum: <5% cover, Growth Form = algae.
This sparsely vegetated open barren occupies ca. 500 sq. m in a heavily disturbed basic woodland that contains some mafic indicators but is generally pedestrian. Seepage is locally present. This outcrop supports a population of the globally rare and enigmatic Talinum sp. nov.
Substrate is primarily bedrock with some loose gravel. Moderate soil development has occurred where forb patches are present; accumulation here was sufficient for soil collection.
