Zephyranthes rosea Lindl.
     Bot. Reg. 10: t. 821.

Synonyms: Atamosco rosea (Lindl.) Greene. 

A modern intentional introduction to Samoa, where it was first collected in 1904, native to Cuba, but now widely cultivated for its showy pink flowers.  Although probably originally introduced as ornamental, it has escaped to become naturalized and locally common in lawns (where it can survive cutting because of its subterranean bulbs) in villages on all the main islands, reported only from the lowlands (where nearly all the villages are located).  Samoan Name: lili (a generic name for many ornamental lily-like plants).  English Name: pink zephyr lily.

       Scapose herb up to 20 cm in height, clump-forming, arising from an underground bulb.  Leaves simple, basal, linear; blade up to 20 cm (but often shorter if grazed or mowed in lawns) × 3–7 mm, gradually tapering at the base, rounded at the tip; surfaces glabrous; margins entire; sessile.  Inflorescence a solitary flower borne atop a leafless scape up to 20 cm long.  Perianth funnelform, rose colored, whitish at the base, with 6 subequal oblanceolate tetals 3–4.5 cm long fused at the base, borne on a pedicel 2.5–4 cm long and subtended by a sheathing lanceolate bract 1.7–2.5 cm long.  Ovary inferior, 3-celled, with a shallowly 3-lobed stigma.  Stamens 6, alternating long and short, inserted at the top or in tube of the perianth.  Fruit a subglobose capsule ca. 1.2 cm in diameter.  Flowering and fruiting occur continuously.

       Distinguishable by its erect, scapose herb habit; linear, basal leaves arising from an underground bulb; solitary, terminal, pink, 6-parted flowers borne atop a leafless stem; and a subglobose, 3-celled capsule.
