Chris Horne of the Wellington Botanical Society recently sent me a fern frond they collected on one of their trips. Although the frond is small and lacking the diagnostic reproductive characters, I think it is the introduced holly fern (Cyrtomium falcatum). It looks like the shining spleenwort (Asplenium oblongifolium), but the
The rare, tetraploid maidenhair spleenwort (Asplenium trichomanes subsp. quadrivalens) has only recently been rediscovered in New Zealand. Several people have contacted me with possible additional sightings. As described by the Scoop website, Jack Ritchie had a maidenhair spleenwort self-sow on a rock used to construct a water feature in his
Botany has recently acquired a unique collection: a special group of calcified red algae known as the corallines. Coralline algae are abundant and ubiquitous throughout the world’s oceans, playing very important roles in marine ecosystems. The encrusting, or crustose, species can form unusual lumpy, warty-looking layers in the intertidal, sometimes

Field-work is one of the best aspects of working as a Natural Environment curator at Te Papa. I get to spend about three weeks a year in the field collecting plant specimens. I’ve recently returned from ten days field-work in the South Island, collecting samples for our research on lancewood
