Triglochin scilloides (Poir.) Mering & Kadereit
Habit: Annual, tufted, in youth submersed, in age +- emergent; roots fibrous. Leaf: 5--20(45) cm, 1--5 mm wide, +- elliptic to +- round in ×-section; ligule +- 1 mm, tip +- obtuse or +- notched. Inflorescence: +- scapose, generally emergent, +- dense spike of bisexual and sometimes staminate flowers, (2)6--20 cm, + 2 submersed, sessile pistillate flowers enclosed in leaf sheath at base of scape. Staminate Flower: perianth part 1, 2--3 mm; stamen 1. Pistillate Flower: perianth 0; carpel 1, style 6--20 cm, thread-like, stigma floating, head-like. Bisexual Flower: perianth part 1, 2--3 mm; stamen 1; carpel 1, style generally short. Fruit: achene, 2--10 mm, ribbed, +- flat, +- winged in bisexual flowers, angled in pistillate flowers, tip truncate with off-center beak. Chromosomes: 2n=12.
Ecology: Vernal pools, streams, ponds, lake margins; Elevation: < 1700 m. Bioregional Distribution: NCo, NCoRI, SN, GV, CW, SCo, PR, GB; Distribution Outside California: to western Canada, Montana, Mexico, Chile; naturalized in Australia, Iberian Peninsula. Flowering Time: Mar--Oct Note: Previously in Lilaea, yet highly nested in Triglochin, a paraphyletic genus made monophyletic by inclusion of this sp. (von Mering & Kadereit 2010).
Synonyms: Lilaea scilloides (Poir.) Hauman
Unabridged Note: Previously in Lilaea, sometimes in Lilaeaceae, but evidence from molecular biology, embryology, cytology, palynology indicates close relationship with Trigochlin, a paraphyletic genus made monophyletic by inclusion of this sp. (von Mering & Kadereit 2010).
