From the US Fish and Wildlife Service proposal for removing 23 species from the Federal Lists of Endangered and Threatened Wildlife and Plants due to extinction:
Phyllostegia glabra
var.
lanaiensis
was listed as endangered on September 20, 1991 (56 FR 47686), and was included in the Lanai plant cluster recovery plan in 1995 (USFWS 1995).
At the time of listing, no wild individuals had been seen since 1914, although there was one questionable sighting from the 1980s that was later considered to be
P. glabra
var.
glabra
(USFWS 1995; 2012). Threats included habitat degradation and herbivory by feral ungulates, the establishment of ecosystem-altering invasive plant species, and the consequences of small population sizes.
Very little is known of the preferred habitat or associated species of
P. glabra
var.
lanaiensis
on the island of Lanai. It has been observed in lowland mesic to wet forest in gulch bottoms and sides, often in quite steep areas
Phyllostegia glabra
var.
lanaiensis
was a short-lived perennial herb. Flowering cycles, pollination vectors, seed dispersal agents, longevity, specific environmental requirements, and limiting factors of
P. glabra
var.
lanaiensis
remain unknown.
