[*][*] Calyx with a small reflexed lobe in each sinus; stamens little exserted.
4. H. appendiculàtum, Michx. Hairy; stem-leaves palmately 5-lobed, rounded, the lobes toothed and pointed, the lowest pinnately divided, cymes rather loosely flowered; filiform pedicels and calyx bristly-hairy.—Damp woods, Ont. to mountains of N. C., west to Minn., Iowa, and Mo. June, July.
2. NEMÓPHILA, Nutt.
Calyx 5-parted, with a reflexed appendage in each sinus, more or less enlarged in fruit. Corolla bell-shaped or almost wheel-shaped; the lobes convolute in the bud; the tube mostly with 10 small folds or scales inside. Stamens included; anthers ovoid or heart-shaped. Placentæ (bearing each 2–12 ovules), capsule and seeds as in Hydrophyllum.—Diffuse and fragile annuals, with opposite or partly alternate pinnatifid or lobed leaves, and one-flowered peduncles; the corolla white, blue, or marked with purple. (Name composed of νέμος, a grove, and φιλέω, to love.) Some handsome species are garden annuals.
1. N. micròcalyx, Fisch. & Meyer. Small, roughish-pubescent; stems diffusely spreading (2–8´ long); leaves parted or deeply cleft into 3–5 roundish or wedge-obovate sparingly cut-lobed divisions, the upper leaves all alternate; peduncles opposite the leaves, shorter than the long petioles; flowers minute; corolla white, longer than the calyx; placentæ each 2-ovuled; capsule 1–2-seeded.—Moist woods, Va. to Fla., west to Ark. and Tex. April–June.
3. ELLÍSIA, L.
Calyx 5-parted, without appendages, enlarged and foliaceous in fruit. Corolla bell-shaped or cylindraceous, not longer than the calyx, 5-lobed above; the lobes imbricated or convolute in the bud, the tube with 5 minute appendages within. Stamens included. Placentæ (each 2-ovuled), fruit, and seeds much as in Hydrophyllum.—Delicate and branching annuals, with lobed or divided leaves, the lower opposite, and small whitish flowers. (Named for John Ellis, a distinguished naturalist, an English correspondent of Linnæus.)
1. E. Nyctèlea, L. Minutely or sparingly roughish-hairy, divergently branched (6–12´ high); leaves pinnately parted into 7–13 lanceolate or linear-oblong sparingly cut-toothed divisions; peduncles solitary in the forks or opposite the leaves, 1-flowered; calyx-lobes lanceolate, pointed, about the length of the cylindraceous (whitish) corolla (in fruit ovate-lanceolate, nearly ½´ long), capsule pendulous. (E. ambigua, Nutt.; merely a slender form.)—Shady damp places, N. J. to Va., west to Minn. and Mo. May–July.
4. PHACÈLIA, Juss.
Calyx 5-parted; the sinuses naked. Corolla open-bell-shaped, 5-lobed; the lobes imbricated in the bud. Filaments slender, often (with the 2-cleft style) exserted; anthers ovoid or oblong. Ovary with 2 narrow linear placentæ adherent to the walls, in fruit usually projecting inward more or less, the two often forming an imperfect partition in the ovoid 4–many seeded capsule. (Ovules 2–30 on each placenta.)—Perennial or mostly annual herbs, with simple, lobed, or divided leaves, and often handsome (blue, purple, or white) flowers in scorpioid raceme-like cymes. (Name from φάκελος, a fascicle.)
