Phoenix loureiroi is named after João de Loureiro; it was originally written by Kunth as "loureirii", but this is an error to be corrected to loureiroi under the provisions of the ICBN.[3]

Description

Phoenix loureiroi contains solitary and clustering plants with trunks from 1–4 m (3.3–13 ft) high and 25 cm (9.8 in) in width, usually covered in old leaf bases. The leaves vary to some degree but usually reach 2 m (6.6 ft) in length with leaflets wide at the base and sharply pointed apices. The leaflets emerge from the rachis at varying angles creating a stiff, plumose leaf.

The fruit is a single-seeded drupe, bluish-black when ripe, produced on erect, yellow inflorescences, usually hidden within the leaf crown. The species is noted for its variability in different habitats.[4]

Varieties

There are two varieties,[3] based on the presence or absence of sclerotic, tannin-filled cells along the midribs and margins of leaflets:

  • Phoenix loureiroi var. loureiroi.
  • Phoenix loureiroi var. pedunculata (Griff.) Govaerts (syn. P. loureiroi var. humilis S.C.Barrow).

Cultural importance

Fibers from P. loureiroi var. loureiroi, known locally as "vuyavuy palm" (also spelled "voyavoy"), are used to make the distinctive vakul headgear and kanayi vests of the Ivatan people in the Batanes Islands of the northern Philippines.[5][6]
