Delissea lanaiensis
Genus: Delissea sect. Macranthae
Status: Extinct. Last collected in 1915.
Range: Lāna'i.
Growth form: Subshrub, 0.6-1.2 m tall.
This species from Lana'i, first described by Hillebrand in 1888 as part of Delissea sinuata. Not until Lammers, 2005, did this population become segregated into its own species. Together, these two species seem closely related to another Macranthae, Delissea fauriei of Moloka'i.
Description: Since Hillebrand described this as a variety of Delissea sinuata without reference to a distinct habit, I have assumed the habit is broadly similar. The habit is subherbaceous and single-stemmed from 0.6 to 1.2 m tall. From the herbarium specimens the stem diameter for D. sinuata is 1.3 - 2 cm wide; those of D. lanaiensis are smaller reaching a maximum of 1 cm in the few specimens that exist.
