AVH map***

Pimelea gigandra is closely related to P. altior, but differs by the greater number of flowers per inflorescence, the longer floral tube and sepals, the hairs on the stems (away from the growing point) more or less appressed, the larger anthers, and the sparser tomentum on the upper leaf surface.
