What Good Photographs Must Have ²

Rengarenga (Arthropodium cirratum) and Arthropodium bifurcatum are easily confused as they look the same (first photograph). To be able to get a species ID you need to photograph the flowers.

• The floral bracts of the rengarenga are lanceolate and that they curl back on themselves (second photograph)
• The floral bracts - and more importantly the smaller inner series of bracts which are 'bifid' (i.e. bifurcate) for Arthropodium bifurcatum (third photograph)
