We are using data from herbarium specimens, field collections and DNA analyses to investigate the taxonomic status of orchids in the genera Corybas (spider orchids), Pterostylis (greenhood orchids), Prasophyllum (leek orchids), Spiranthes (lady’s tresses orchid) and Thelymitra (sun orchids).
For decades some of these orchids have been only known by tag-names (nicknames) and, although they are not officially recognised as species, many have already joined the list of New Zealand’s threatened plants.
