Higher Taxonomy
Family: PlantaginaceaeView DescriptionDichotomous Key

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, Limosella, Mimulus, Myoporum, Scrophularia, Verbascum). California Maurandya moved to Holmgrenanthe and Maurandella. Limnophila ×ludoviciana Thieret an occasional agricultural weed in rice fields. Hebe ×franciscana (Eastw.) Souster, Hebe speciosa (R. Cunn.) Andersen only cultivated.

Genus: AntirrhinumView DescriptionDichotomous Key

Common Name: SNAPDRAGON
Habit: Annual, perennial herb, glabrous to hairy. Stem: ascending, erect, or vine-like, often clinging by twining pedicels or branchlets. Leaf: proximal generally opposite, distal alternate, generally reduced distally on stem; veins pinnate. Inflorescence: cleistogamous or opening; raceme or flower 1 in axils. Flower: uppermost calyx lobe generally largest; corolla tube of opening flowers truncate or with rounded sac-like extension at base, lower lip base generally swollen, closing throat; stamens 4, generally included, staminode 0; style included, straight or curved, glabrous or glandular-puberulent to near tip, stigma inconspicuous. Fruit: ovoid to spheric; chambers 2, generally dehiscent by 1--2 pores near tip, lower chamber generally larger, upper occasionally indehiscent. Seed: many, generally with tubercles or netted ridges, winged or not.
Species In Genus: 35 species: western North America, western Mediterranean. Etymology: (Greek: nose-like, from corolla shape) Note: North America taxa more closely related to Mohavea than to Mediterranean taxa; revision needed. Antirrhinum cyathiferum moved to Pseudorontium.

Antirrhinum vexillocalyculatum Kellogg
NATIVE
Habit: Annual, branched or not, glabrous to hairy proximal to inflorescence. Stem: erect but weak, often clinging to other plants or debris. Leaf: petiole 0--27 mm; blade 1.5--60 mm, elliptic to ovate or oblong, tip obtuse to rounded. Inflorescence: raceme-like or flowers 1 in axils, glandular-hairy, flowers all opening; pedicels 1--4 mm, proximal-most subtended by twining branchlets, flower branchlets, or both. Flower: calyx lobes unequal; corolla lavender, veins often vaguely darker, throat uniformly narrowed, curved upward at mouth, lower lip lobes conspicuous, thrust forward, erect or spreading. Fruit: 4--8 mm; dehiscent by 3 pores at tip, 1 in upper chamber, 2 in lower. Seed: 0.7--1.3 mm, ovoid, dark brown to black, tubercled, ridged. Chromosomes: n=15.
Note: Subspecies intergrade in NCoR (except Antirrhinum vexillocalyculatum subsp. vexillocalyculatum).
