Common Name: PLANTAIN FAMILY Habit: Annual to shrub, some aquatic. Leaf: basal or cauline, alternate or opposite (whorled), simple, entire to dentate or lobed, venation generally pinnate; stipules 0. Inflorescence: raceme, spike, or flowers axillary in 1--few-flowered clusters; flowers few to many, each subtended by 1 bract. Flower: unisexual or bisexual, radial or bilateral; sepals 4--5, generally fused at base; corolla 4--5-lobed, scarious or not, persistent or not, generally 2-lipped, upper lip generally 2-lobed, lower generally 3-lobed, spur present or not, tube sac-like at base or not; stamens 2 or 4, alternate corolla lobes, epipetalous, staminode 0 or 1--2, anthers opening by 2 slits; ovary superior, [1]2--4-chambered, style 1, stigma lobes 0 or 2. Fruit: generally a capsule, septicidal, loculicidal, circumscissile, or dehiscing by terminal slits or pores. Genera In Family: +- 110 genera, +- 2000 species: worldwide, especially temperate. Note: Veronicaceae sensu Olmstead et al. Recently treated to include Callitrichaceae, Hippuridaceae, and most non-parasitic California genera of Scrophulariaceae (except Buddleja, Diplacus, Erythranthe, Limosella, Lindernia, Mimetanthe, Mimulus, Myoporum, Scrophularia, Verbascum). California Maurandya moved to Holmgrenanthe and Maurandella. Mohavea moved to Antirrhinum. Limnophila ×ludoviciana Thieret an occasional agricultural weed in rice fields. Hebe ×franciscana (Eastw.) Souster, Hebe speciosa (R. Cunn.) Andersen only cultivated. eFlora Treatment Author: Margriet Wetherwax, except as noted Scientific Editor: Robert W. Patterson, Bruce G. Baldwin.
Common Name: WATER-STARWORT Habit: Annual [perennial herb], in water or on wet ground; monoecious [dioecious]. Stem: slender, generally ascending under water, floating on surface, or prostrate on ground, generally much-branched. Leaf: generally opposite, 4-ranked, lance-linear to spoon-shaped, entire [lobed]. Inflorescence: flowers 1--2(4) per leaf axil, bracts 2, +- white, generally inflated, or 0. Flower: minute, unisexual; perianth 0. Staminate Flower: stamen 1, filament elongate. Pistillate Flower: ovary superior, slightly lobed at tip and base, chambers 4, styles 2, thread-like. Fruit: 0.6--1.6[2.4] mm, +- dry, +- grooved lengthwise, splitting into 4 achene-like units. Etymology: (Greek: beautiful hair, from long linear submerged leaves of some of Medit taxa) Note: Taxonomically difficult; mature fruit and 10× magnification needed for identification. Callitriche peploides Nutt. a nursery weed in southern California; Callitriche stenocarpa Hegelm., misappl. to various California taxa, but recorded from many sites in the Rocky Mountains and could be expected in California. eFlora Treatment Author: Richard V.

Habit: Plant scattered or forming extensive stands, submerged or with floating rosettes, or dense mats when terrestrial. Leaf: submersed leaves linear-oblong; floating, emergent, or terrestrial leaves often present, spoon-shaped leaves often abruptly narrowed to petiole; often with floating rosette. Inflorescence: bracts 2, inflated, persistent in fruit or not. Fruit: subsessile; wing generally 0 or only distal to middle. Note: Varieties poorly distinguished.

MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
