위키페디아 설명
Howea belmoreana, the curly palm, kentia palm, or Belmore sentry palm, is a species of flowering plant in the family Arecaceae, endemic to Lord Howe Island, Australia. It and Howea forsteriana probably evolved from a common ancestor through sympatric speciation.[2] The canopy of a mature kentia palm tree spreads 5–10 ft (2–3 m) in diameter and contains roughly 36 leaves.[3]

Howea belmoreana has gained the Royal Horticultural Society's Award of Garden Merit.[4][5]
Effects of mycorrhiza on speciation
Howea belmoreana is restricted to the volcanic soils on Lord Howe Island, whereas H. forsteriana is found on both alkaline calcareous and volcanic soils, the two most common soil types found on the island. Howea belmoreana is more common on volcanic soils and has a higher survival rate than H. forsteriana.[6] Osborne et al. (2018) suggest that the speciation of H. forsteriana and Howea belmoreana is partially a result of difference in arbuscular mycorrhiza based on soil types. The levels of arbuscular mycorrhizal fungi were significantly lower in the roots of Howea forsteriana on volcanic soil, compared to the same species on calcareous soil and to Howea belmoreana on the same volcanic soil. The symbiotic relationship between the plant and the fungi exchanges carbons from the plant for essential nutrients such as nitrogen and phosphate that would be otherwise inaccessible to the plant. The decreased fungal relationships in Howea forsteriana in volcanic soil may disadvantage it compared to Howea belmoreana.[7]

This monoecious, pinnate palm grows to about 40'/12m tall and has a closely ringed green trunk about 6 inches/15cm in diameter. The leaves are striking and markedly recurved, nearly forming a half circle in their arching up, out and down. The leaves are quite long, but the width of the entire palm is much less than the doubled length of the leaves because of their extreme recurving. The leaflets grow up and out away from the rachis forming a pronounced 'V', in sharp contrast to the droopy, downward pointing leaflets of its cousin, Howea forsteriana. The inflorescences are unbranched, also in constrast to H. forsteriana, though the fruits are similar shape and color (dark red and ovoid). There is no crownshaft.
