Godetia (C. H. Godet, Swiss botanist). Onaqraceae. Mostly erect annuals with very showy flowers in leafy racemes or spikes. Calyx-tube obconic or funnelform; petals rose, lilac- purple or white, often marked with a large deep crimson or purple spot; stamens 8; ovary 4-celled, inferior: fr. a many-seeded caps. — Twenty or more species in the western parts of S. and N. Amer., especially Calif. Seed may be surface-sown in the late fall in order to be covered by the rains which follow, or in February lightly covered in sunny or in half-shady places. G. amoena is very popular and furnishes an abundance of bloom in early summer when many late spring annuals have succumbed to advancing heat. In the wild garden the species come again freely but have a tendency to move to new ground after the second year. G. decumbens, Douglas. Sts. ascending, strongly flattened, whitish pubescent: ovary white-woolly. B.M. 2889. B.R. 1221. —Not certainly known in a wild state. Seed originally from Ore. Differs little technically from G. quadrivulnera or its forms but is quite unchanged in its characters after 75 years or more of cult, in European gardens. It is an excellent illustration of the manner in which many strains of the smaller-fid, godetias maintain their slight but distinctive characters, although subject for many years to the varying conditions of garden cult.—G. magellanica, Burbank, a diffuse free-flowering species with lavender fls. the size of G. amoena, has been recently intro. from Patagonia by Luther Bur- bank.—G. quadrivulnera, Spach. Erect, slender, pubescent: lvs, obovate to linear or the uppermost lanceolate and half-conduplicate: petals lilac or pale crimson, usually with a spot at apex, 4-6 lines long: caps, sessile, 4-sided, lightly 8-ribbed. B.R. 1119. Occasionally cult., but probably not in the trade.—G. romanzovii, Spach, from the "northwest coast." not now known in a wild state, has been cult, in Eu. nearly a century. Very leafy with young parts white-pubescent: lvs. obtong-oblanceolate. B.R. 562. W. L. Jepson. Clarkia (Capt. Wm. Clark, companion of Lewis, explorer of the Rocky Mt. region and beyond, 1806). Onagraceae. Flower - garden annuals. Herbs, with alternate mostly entire lvs., and showy fls. in the upper axils or in terminal racemes: fls. regular, the calyx tubular, the petals 4, narrow at the base and entire or lobed, wide-spreading; stamens 8, the alternate ones short or rudimentary; stigmas 4, large and spreading: pod oblong or linear, 4-sided.—Half dozen or more species in W. N. Amer. See also Eucharidium. Clarkias are hardy annuals of easy cultivation. They thrive in a warm, light soil, either fully exposed to the sun or in partial shade. They are useful for low masses or for edgings; also for vases and baskets. They have been much improved by domestication. CH
