This plant was feared extinct when the last known individuals died in 1996. Six plants were discovered in 2000, but by 2005 these were also dead. As of 2004 there was only a single individual remaining in the wild, a very large plant spanning over four meters which may actually be more than one individual growing together. Cuttings have been collected from this plant.[3]

This Hawaiian mint is a woolly vine which can reach 1 or 2 meters in length. The woolly leaves are up to 14 centimeters long by 4.8 wide. The plant produces tubular flowers which may be over 4 centimeters long. They are white or yellowish with purple-pink lips.[1] The plant reproduces vegetatively, rooting where the stems contact the substrate and growing up new, cloned plants.[3]
