Common Name: WATERLEAF FAMILY Habit: Annual, perennial herb, generally hairy, generally taprooted. Stem: prostrate to erect. Leaf: simple to pinnately compound, basal or cauline, alternate or opposite; stipules 0. Inflorescence: cyme, generally raceme-like and coiled, or flowers 1. Flower: bisexual, generally radial; calyx lobes generally 5, generally fused at base, generally persistent, enlarging in fruit; corolla rotate to cylindric, generally deciduous, lobes generally 5, appendages in pairs on tube between filaments or 0; stamens generally 5, epipetalous, filament base sometimes appendaged, appendages scale-like; ovary generally superior, chambers 1 or 2, placentas 2, parietal, enlarged into chamber, sometimes meeting so ovary appears 2--5-chambered, style 1, style branches 2, stigmas generally head-like. Fruit: capsule, generally loculicidal; valves generally 2. Genera In Family: 12 genera, 240--260 species: especially western US; some cultivated (Emmenanthe, Nemophila, Phacelia). Note: Included in Boraginaceae in TJM2 and some other treatments (Angiosperm Phylogeny Group IV 2016 Bot J Linn Soc 181:1--20) but treated as separate family (excluding Namaceae) by Boraginales Working Group (Luebert et al. 2016). eFlora Treatment Author: Genevieve K. Walden, Robert W. Patterson & Richard R. Halse, except as specified Scientific Editor: Bruce G. Baldwin
Habit: Annual to perennial herb, generally glandular-hairy, taprooted or from +- thick caudex. Leaf: generally cauline, generally alternate, simple to 2-pinnately compound, generally +- reduced upward. Inflorescence: cyme, generally dense, coiled, generally 1-sided; pedicels generally <= 5 mm, generally straight. Flower: sepals generally 5, generally fused at base, generally equal, generally +- alike, generally persistent, enlarging in fruit; corolla generally deciduous, at least some persistent and withering in fruit in some species, rotate to tubular or bell- or funnel-shaped, +- white, blue, purple, pink or yellow, tube and throat not always clearly differentiated, generally glabrous inside, scales of tube base 0 or free from or fused to filament bases, generally white, nectary gland on petal midvein generally 0, each petal with generally 0, sometimes 2--many translucent areas, 2 or 4 of which parallel; stamens generally attached at same level, generally equal, generally exserted, bases generally not wider, with 2 or generally 0 wings, filaments generally white, pollen generally tan; ovary chamber 1, sometimes appearing as 2 due to intrusion of the 2 placentas, placentas parietal, enlarging and meeting in fruit, style 2-lobed, generally hairy proximal to lobes, disk proximal to ovary generally inconspicuous. Fruit: capsule, oblong to spheric, generally rounded at base, generally beaked. Seed: 1--many (number sometimes due to ovule abortion), oblong to spheric, generally brown; abaxially generally pitted or cross-furrowed. Etymology: (Greek: cluster, from dense inflorescence) Toxicity: Dermatitis caused by contact with hairs, especially glandular, of P. campanularia, P. crenulata, P. ixodes, P. minor, P. parryi, P. pedicellata (Reynolds et al. 1986 Contact Dermatitis 14:39--44). Note: Some California per species intergrade, hybridize, difficult to distinguish. Phacelia ixodes Kellogg, included in TJM (1993), not known from California. Since TJM2, Phacelia dalesiana J.T. Howell transferred to Howellanthus as Howellanthus dalesianus (J.T. Howell) Walden & R. Patt. Regarding indument in this treatment: minute (for e.g., puberulent) < 0.2 mm; short = 0.2--2 mm; long > 2 mm. eFlora Treatment Author: Genevieve K. Walden, Robert W. Patterson, Laura M.

(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurrence).
MAP LEGEND View all CCH records 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.
