Common Name: PHLOX FAMILY
Habit: Annual, perennial herb, shrub, vine. Leaf: simple or compound, cauline (or most basal), alternate or opposite; stipules 0. Inflorescence: cymes, heads, clusters, or flower 1; bracts in involucres or not. Flower: sepals generally 5, fused at base, translucent membrane generally connecting lobes, torn by fruit; corolla generally 5-lobed, radial or bilateral, salverform to bell-shaped, throat often well defined; stamens generally 5, epipetalous, attached at >= 1 level, filaments of >= 1 length, pollen white, yellow, blue, or red; ovary superior, chambers generally 3, style 1, stigmas generally 3. Fruit: capsule. Seed: 1--many, when wetted swelling or not, gelatinous or not.
Genera In Family: 26 genera, 314 species: America, northern Europe, northern Asia; some cultivated (Cantua, Cobaea (cup-and-saucer vine), Collomia, Gilia, Ipomopsis, Linanthus, Phlox). Note: Leptodactylon moved to Linanthus.

Genus: NavarretiaView DescriptionDichotomous Key

Common Name: NAVARRETIA
Habit: Annual, generally prickly. Stem: prostrate to generally erect; branches ascending or spreading; glabrous to generally hairy, often glandular. Leaf: simple, alternate (lowermost opposite), entire to generally deeply pinnate-lobed. Inflorescence: generally head-like, bracts pinnate- to palmate-toothed or -lobed, spine-tipped (flower 1--2, pedicels elongate, bracts entire, not spine-tipped). Flower: calyx lobes 4--5, equal, entire or toothed, or unequal, spine-tipped; corolla lobes 4--5; stigmas 2 or 3. Fruit: generally ovoid, chambers 1--3; dehiscing when wetted, seeds adherent to fruit and each other, or generally dehiscing at maturity, seeds free. Seed: 1--many per fruit, brown, gelatinous when wet. Chromosomes: 2n=18.
Species In Genus: +- 40 species: western North America, Argentina, Chile. Etymology: (F.F. Navarrete, Spanish physician, ?--1742) Note: Revised taxonomy, too late for full treatment in TJM2, includes Navarretia linearifolia (Howell) L.A. Johnson subsp. linearifolia, a +- cryptic segregate of Navarretia sinistra, and Navarretia linearifolia subsp. pinnatisecta (H. Mason & A.D. Grant) L.A. Johnson [Navarretia sinistra subsp. pinnatisecta] (Johnson & Cairns-Heath 2010 Syst Bot 35:618--628); Navarretia paradoxinota and Navarretia paradoxiclara, both new to science, and Navarretia propinqua [Navarretia intertexta subsp. propinqua] (Johnson et al. 2013 Phytotaxa 91:27--38). Relative positions of flower parts are as pressed, unless stated otherwise.

Species: Navarretia leucocephalaView Description 

Habit: Plant erect to prostrate, 1° axes 1--several. Stem: 3--15 cm, branches ascending to prostrate; puberulent or hairy below heads, hairs recurved. Leaf: 1--2-pinnate-lobed; lobes linear; lower leaves glabrous, upper hairy at base. Inflorescence: outer bracts leaf-like, lobes needle-like, 2--4-branched at base, lobes near tip 2, shorter, entire, ascending; inner bracts simpler, base membranous-winged, ciliate, wing width > midrib. Flower: calyx lobes glabrous or +- hairy, tapered, gland-dotted below, membranes truncate, ciliate; corolla 4--10 mm, lobes with 1 vein entering base; stamens exserted; stigmas 2, minute. Fruit: translucent, dehiscing when wetted.
Note: Some subspecies intergrade. Variable with water level, duration.

Navarretia leucocephala Benth. subsp. leucocephala
NATIVE
Stem: 2--22 cm. Inflorescence: longer bracts > 2 × head, lobes 3--4-branched abaxially. Flower: calyx lobes generally glabrous; corolla white, tube exserted, lobes narrowly ovate; style exserted. Chromosomes: 2n=18.
