2. BOWLESIA, Ruiz & Pavon. 
CalyX’teeth rather prominent. Petals elliptical, obtusish. Fruit broadly ovate 
in outline, with a narrow commissure, turgid, becoming depressed on the back, 
without ribs or oil-tubes. Seed flat on the face, slightly hollowed on the back, not 
filling the calyx. — Slender herbs, with scattered stellate pubescence ; leaves oppo- 
site, simple, with scarious and lacerate stipules ; flowers white, minute, in simple 
few-flowered umbels on axillary peduncles. 
A dozen species, chiefly South American, one ranging northward to Mexico, Arizona, and 
California. 
1. B. lobata., Ruiz & Pavon. Annual, weak and slender, thinly pubescent, the 
stems dichotomously branched, a foot or two long : leaves thin, reniform to cordate, 
J to IJ inches broad, shorter than the slender petioles, deeply 5-lobed, the acutish 
lobes entire or 1 - 2-toothed: peduncles much shorter than the petioles; the umbels 
1 - 4-flowered : fruit a line long, sessile or nearly so, pubescent, the inflated calyx 
not adherent to the carpels, which are at first but partially occupied by the seed, — 
FI. Peruv. iii. 28, t. 251 ; Torr. & Gray, FI. i. 601. 
In damp shady places, from the Sacramento Valley southward, rather rare. The species 
doubtless includes B. tenera, Sprengel. 
3. ERYNGIUM, Tourn. Button Snakeeoot. 
Calyx-teeth manifest, rigid and persistent. Fruit ovoid or obovoid, scarcely com- 
pressed, covered with hyaline scales or vesicles ; the ribs obsolete, and oil-tubes (in 
our species) wanting ; carpels and seeds semi-terete. — Herbs, chiefly perennial ; 
leaves rigid spinosely toothed or divided; flowers white or blue, sessile
