PLANTAGINACEAE PLANTAIN FAMILY

Margriet Wetherwax, except as noted

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.
110 genera, ± 2000 species: worldwide, especially temperate. [Angiosperm Phylogeny Group 1998 Ann Missouri Bot Gard 85:531–553; Olmstead et al. 2001 Molec Phylogen Evol 16:96–112] 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. —Scientific Editors: Robert Patterson, Bruce G. Baldwin.

Key to Plantaginaceae

ANTIRRHINUM SNAPDRAGON

Margriet Wetherwax & David M. Thompson

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.
35 species: western North America, western Mediterranean. (Greek: nose-like, from corolla shape) [Oyama & Baum 2004 Amer J Bot 91:918–925; Vargas et al. 2004 Plant Syst Evol 249:151–172] North America taxa more closely related to Mohavea than to Mediterranean taxa; revision needed. Antirrhinum cyathiferum moved to Pseudorontium.

Key to Antirrhinum

A. ovatum Eastw. OVAL-LEAVED SNAPDRAGON
NATIVE
Annual, glandular-hairy. Stem: erect but weak, often clinging to other plants or debris, 8–60 cm. Leaf: petiole 0–15 mm; blade 4–49 mm, lanceolate to obovate. Inflorescence: raceme-like or flowers 1 in axils, flowers all opening; pedicels 2–5 mm, proximal-most generally subtended by twining branchlets. Flower: calyx lobes unequal, 4–5 mm, upper 11–12 mm; corolla 17–20 mm, cream, pink-tinged, lower lip base not swollen, not closing throat, throat floor with 2 longitudinal folds (unique in genus). Fruit: 7–10 mm, oblique-ovoid, chambers unequal; style projecting forward. Seed: ± 1 mm, ovate, black, ridged.
n=16. Heavy, adobe-clay soils on gentle, open slopes, also disturbed areas; 200–1400 m. s San Joaquin Valley (especially w Kern, e San Luis Obispo cos.), s Inner South Coast Ranges, w Western Transverse Ranges. Abundant every 20–50 years. May–Jul [Online Interchange] {CNPS list}
