Dubautia carrii B. G. Baldwin & Friar

Compact to diffusely branched shrubs mostly 10-25 dm tall, leaves opposite.  Diagnostic features of the species include 1) opposite, nearly glabrous to sparsely glandular, mostly narrowly elliptic-lanceolate leaves with margins 1-4 toothed on each side distally, 2) capitulescences 2-17 x 2-10 cm, bearing 20-150+ heads, and 3) false involucral bracts moderately to densely sessile- and stipitate-glandular.  Most flowering specimens have been collected from September to November.

This species is very similar to D. hanaulaensis, differing primarily in its larger stature, slightly broader leaves, and larger capitulescences with more numerous heads exhibiting more copiously glandular false involucres.  

Recognition of D. carrii and D. hanaulaensis as separate species is supported by molecular data that place them in different clades, and together with biogeographic evidence, suggest that their similarities are due to retained ancestral or plesiomorphic traits present in their most recent common ancestor.

Dubautia carrii is known only from E Moloka'i, mostly on the upper slopes and summits in the vicinity of Kaunakakai and Kawela Gulches from 700-1150 m elevation.  Annual precipitation at sites occupied by the species is about 125-200 cm.
