큰미국연영초-[정명] Trillium chloropetalum Howell

Trillium chloropetalum, also known as giant trillium, giant wakerobin, or common trillium, is a species of flowering plant in the family Melanthiaceae. It is endemic to the western U.S. state of California, being especially frequent in and around the San Francisco Bay Area.

Description

Trillium chloropetalum is a perennial, clump-forming herbaceous plant with a thick underground rhizome. Like all trilliums, it has a whorl of three bracts (leaves) and a single trimerous flower with 3 sepals, 3 petals, two whorls of 3 stamens each, and 3 carpels fused into a single ovary with 3 stigmas. Since its flower has no stalk, T. chloropetalum belongs to subgenus Sessilia, the sessile-flowered trilliums. It is one of the largest of all Trillium species, with a scape (stem) from 20 to 70 cm (7.9 to 27.6 in) long. The bracts are broadly ovate, 7 to 21 cm (2.8 to 8.3 in) long and 7 to 18 cm (2.8 to 7.1 in) wide, usually with brownish mottling but sometimes unmottled. Petal color is highly variable, typically ranging from pale greenish yellow to greenish bronze (or purplish green) to dark purple. A variety that lacks yellow pigments has petal colors ranging from white to reddish-purple. The flower petals enclose purple stamens, 15 to 30 mm (0.59 to 1.18 in) long, and a purple ovary. Flowering occurs from late February to early April.

In the San Francisco Bay Area, a white-petaled form of T. chloropetalum is often confused with T. albidum, which also has white petals. The former is distinguished by the purple pigment in its anther connective tissue, a character lacking in T. albidum.
