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.
