Antirrhinum nuttallianum subsp. nuttallianum


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, 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.

Genus: AntirrhinumView DescriptionDichotomous Key

Common Name: SNAPDRAGON
Habit: Annual, perennial herb, glabrous to hairy, often glandular. Stem: ascending, erect and self-supporting, or vine-like, often clinging by twining pedicels or branchlets. Leaf: proximal generally opposite, distal alternate, generally +- reduced distally on stem; veins pinnate. Inflorescence: raceme or flowers 1 in axils. Flower: cleistogamous or opening; calyx lobes +- equal or uppermost generally largest; corolla tube of opening flowers truncate or with rounded sac-like extension at base, lower lip base generally swollen, closing throat; stamens 2 or 4, generally included, staminode 2 or 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.
Etymology: (Greek: nose-like, from corolla shape) Note: Antirrhinum cyathiferum moved to Pseudorontium.

Species: Antirrhinum nuttallianumView Description 


Habit: Annual, rarely biennial, glandular-hairy. Stem: erect but weak, often clinging to other plants or debris. Leaf: petiole < 25 mm; blade < 60 mm, ovate, acute, mucronate. Inflorescence: flower 1 in axils, opening and cleistogamous; pedicels generally 2--18(25) mm, proximal-most generally subtended by twining branchlets, flower branchlets, or both. Flower: calyx lobes +- equal; cleistogamous flowers minute, white; corolla of opening flowers 7--12 mm, lavender to blue-purple with 1--2 blue-veined white blotches on lower lip base and gold hairs in mouth (hair color unique in California plants). Fruit: oblique-ovoid; chambers unequal, dehiscent by 3 pores at tip, 1 in upper chamber, 2 in lower. Seed: < 1 mm, ovoid, brown. Chromosomes: n=16.
Note: Subspecies hybridize near coast.
Antirrhinum nuttallianum Benth. ex A. DC. subsp. nuttallianum
NATIVE

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.
