Linear-leaved Honohono (Haplostachys linearifolia)
This species from the Mint-family, which was found on the islands of Maui and Moloka’i, Hawaiian Islands, was described in 1943, apparently based on herbarium specimens, since it was last seen in 1928.
The species was obviously quite similar to the closely related and likewise nearly extinct Honohono (Haplostachys haplostachya (A. Gray) H. St. John) from the islands of Hawai’i, Kaua’i and Maui.
