General Information

Xylosma crenatum is a dioecious (plant bears only male or female flowers, and must cross-pollinate with another plant to produce viable seed) long-lived perennial tree in the flacourtia family (Flacourtiaceae), growing up to 14 m (46 ft) tall, and with dark gray bark. The somewhat leathery leaves are oval to elliptic-oval, about 10 to 20 cm (4 to 8 in) long and 6.5 to 10.0 cm (2.5 to 4.0 in) wide, with coarsely toothed edges and moderately hairy undersides. The female flowers (male flowers have not been described) occur in clusters of 3 to 11 per leaf axil. The four oval sepals are about 2.5 mm (0.1 in) long; petals are absent. The young berries are oval to elliptic-oval and about 7.0 mm (0.3 in) long (mature fruits have not been seen).

Habitat Requirements

Xylosma crenatum occurs in diverse Acacia koa (koa) Metrosideros polymorpha (ohia) montane mesic or wet forest, or M. polymorpha Dicranopteris linearis (uluhe) montane wet forest between 936 and 1,284 m (3,070 and 4,212 ft) elevation. Associated native plant species include Athyrium sandwicensis (akolea), Cheirodendron spp. (olapa), Claoxylon sandwicense (poola), Coprosma spp. (pilo), Cyanea spp. (haha), Diplazium sandwichianum (hoio), Dubautia knudsenii (naenae), Kadua spp. (manono), Ilex anomala (kawau), Lobelia yuccoides (panaunau), Myrsine spp. (kolea), Nestegis sandwicensis (olopua), Perrottetia sandwicensis (olomea), Pleomele aurea (hala pepe), Poa sandvicensis, Pouteria sandwicensis (alaa), Psychotria spp. (kopiko), Scaevola procera (naupaka kuahiwi), Streblus pendulinus (aiai), Polyscias spp. (oheohe), Touchardia latifolia (olona), and Zanthoxylum dipetalum (ae).

Movement / Home Range

Xylosma crenatum occurred in the past on the west side of the Waimea Drainage Basin and along the banks of Mohihi Stream at the edge of the Alakai Swamp. At the time it was listed as endangered, it occured along upper Nualolo Trail in Kuia NAR and along Mohihi Road between Waiakoali and Mohihi drainages in Na Pali-Kona FR. It currently occurs in Kainamanu, Nualolo Trail, and Mohihi Valley.

Reproductive Strategy

Xylosma crenatum may flower infrequently or have short flowering and fruiting periods. The species has dioecious flowers (with male and female flowers on separate plants). Male trees were noted to be flowering in May and August, and displayed fruiting in January, August, October, and November. Its pollination vectors, seed dispersal agents, longevity, specific environmental requirements, and limiting factors are unknown.

Other

More coarsely toothed leaf edges and hairy undersides of the leaves distinguish X. crenatum from the other Hawaiian member of this genus.
