Bergbambos tessellata (Poaceae) endemic to southern Africa: new record from the Limpopo Province, South Africa

Abstract

Bergbambos is a temperate C3 bamboo grass genus, consisting of one species found mainly along southern African mountain ranges (Temperate Afromontane Region). We document here a new record of Bergbambos tessellata found in the Thabazimbi area along Hamerkop Street near the fence of an old nursery (non-functional). The specimen was identified at the National Herbarium (PRE) using a light microscope and compared with other herbarium specimens or materials, collected from other South African provinces. This discovery is accompanied by diagnostic features for precise species differentiation, as well as illustrations facilitating visual distinction. Notably, Bergbambos tessellata exhibits an unusual geographical range in the Waterberg Biosphere region within the valley. This discovery not only enriches our comprehension of bamboo dispersion dynamics but also engenders a heightened impetus for in-depth investigation into the various factors that underlie its restricted presence within this specific ecological niche. The documentation of this species therefore holds considerable importance in formulating effective conservation strategies and promoting sustainable management practices.
