Phacelia (Greek, duster; on account of the crowded flower-clusters of the first described species). Hydrophyllaceae. Annual and sometimes perennial herbs, grown for the blue, purple, or white flowers. Low or not tall plants, with alternate simple or compound lvs. and infl. in more or less scorpioid cymes or spikes: corolla deciduous as the caps, enlarges, in various shades of blue, purple, or white; tube with or without interval appendages, these when present in the form of 5 or 10 vertical folds or projections, adnate to or free from the bases of the filaments; calyx-lobes commonly narrow, often enlarged upward, especially in fr.; style more or less 2-lobed: seed-coats reticulated or pitted.—Species 114. as defined by Brand in hft. 59 (IV. 251) of Engler's Das Pflanzenfamilien" (1913), American, mostly from W. N. Amer. The plants are hairy, nearly smooth, or glandular in whole or in part. The herbage of some of the glandular-hairy species has an offensive odor. The genus includes the old genera Whitlavia, Eutoca, Microgenetes, Cosmanthus, and others. The flowers are mainly of a handsome blue or violet, many species and varieties running through lighter shades to pure white, but not to yellow. The annuals are of easy cultivation, requiring, to bring them to perfection, a soil warm, sunny, and not too moist. Some species like a sandy soil, others a firmer clay. Some are erect and give the best effects when planted thickly; others are more spreading and therefore require considerable space. In height they vary from only a few inches to 2 to 3 feet. The flowers are borne on more or less recurved racemes that straighten as the flowering proceeds. They vary from 1 inch long in some species to less than 1/4inch in others. In addition to those described below there are many other beautiful species of phacelia that should be in the trade. The species best known in cultivation is P. Whitlavia, a garden annual known as whitlavia. INDEX. alba, 4. 13. fimbriata, 2. multiflora, 7. albiflora, 3. glanduloea, 11. Orcuttiana, 1. bipinnatifida. 10. gloxinioidea, 4.
