Speargrasses, with their sharp leaves and flower spikes, may look like a plant you want to avoid at all costs but a number of critters call them home, including the charismatic speargrass weevils. Science researcher Lara Shepherd introduces these weevils, plus some other critters that utilise speargrass plants. When I
The large-leaved Aciphylla speargrasses or taramea are difficult plants to collect. Their rigid leaves are tipped in a sharp point and the bracts on their flower spikes are similarly ferocious. These defences are thought to have evolved to avoid browsing by moa, but they also work against botanists! Consequently, speargrasses are under‑represented in plant collections (herbaria). Te Papa Research Scientist Lara Shepherd and Botany Curator Leon Perrie describe how they approached sampling speargrasses on their recent collecting trip.
Sun, rain, hail, mist and snow – Research Scientist Lara Shepherd and Botany Curator Leon Perrie encountered them all over an epic six-week plant collecting trip late in 2022. Their aim was to collect Aciphylla speargrasses for a research project to determine the number of species. Here is an overview
Aotearoa New Zealand has a plethora of weird and wonderful plants. The ferociously spiky speargrasses are some of our most distinctive plants and an iconic feature of New Zealand’s high-country, especially when flowering. Te Papa Research Scientist Lara Shepherd and Botany Curator Leon Perrie recently embarked on a new project
