Tetramolopium arenarium (NCN)
Tetramolopium arenarium is a short-lived perennial and an upright,
branched shrub in the sunflower family (Asteraceae). Alternate leaves
are lance-shaped, hairy, glandular, and gray-green. This species is
separated from other species of the genus in the Hawaiian Islands by
several characters: Upright habit; number of heads per flower cluster;
presence and type of glands and hairs; size of male ray flowers; number
and color of bisexual disk flowers; and fruit shape and pubescence.
Three infra-specific taxa are recognized: Tetramolopium arenarium ssp.
arenarium var. arenarium (from Maui and Hawaii); T. arenarium ssp.
arenarium var. confertum (from Hawaii); and T. arenarium ssp. laxum
(from Maui). These taxa are distinguished by a combination of
characters. Tetramolopium arenarium ssp. arenarium var. confertum and
T. arenarium ssp. laxum have not been seen the late 1800s (Lowrey
1999).
Little is known about the life history of Tetramolopium arenarium.
Flowering cycles, pollination vectors, seed dispersal agents,
longevity, specific environmental requirements, and limiting factors
are unknown (Service 1996a; 59 FR 10305).
Tetramolopium arenarium was historically known from the islands of
Maui and Hawaii. The species was considered extinct until T. arenarium
ssp. arenarium var. arenarium was recently rediscovered on the island
of Hawaii. Both subspecies were last seen on Maui in the late 1800s
(GDSI 2001; HINHP Database 2001; Service 1996a; 59 FR 10305).
Nothing is known about the preferred habitat of or native species
associated with Tetramolopium arenarium on Maui (Service 1996a; 59 FR
10305; R. Hobdy, pers. comm., 2001), and nothing is known of the
threats to Tetramolopium arenarium on the island of Maui (Service
1996a; 59 FR 10305).
