Cunonia

(named for John Christian Cuno, who catalogued his garden in Amsterdam at the middle of the 18th century). Cunonidceae; formerly included in the Saxifragdceae. A half dozen trees or shrubs of the southern hemisphere, one of which is sometimes grown under glass. Leaves opposite, petiolate, thick and leathery, 3-foliolate or odd-p inn ate: flowers white, in dense spike - like racemes; calyx-tube short, the limb 5 - parted; petals 5; stamens 10: fruit a coriaceous beaked caps. C. capen-sis, Linn., in moist woody places in Cape Colony, is a large glabrous shrub or tree to 50 ft.: leaflets 2-3 pairs, oblong-lanceolate, sharply serrate: flowers small, very numerous, in opposite racemes, the stamens much exserted. Said to be of easy cult, in a sandy-peaty soil; prop, by cuttings of half-ripened wood. l. H. B.

Curatella

(name refers to the plants being used or worked: used for polishing weapons and metal). Dilleniaceae. Three or 4 S. American and W. Indian small trees or scandent shrubs, of which one is sometimes mentioned in horticultural literature. They are warmhouse evergreens, with white flowers in dense panicles. Sepals and petals 4-5; stamens many; carpels 2 (rarely 1), more or less cohering, follicular. C. ameri

Cana

Linn., of W. Indies and S. Amer., grows to 10 ft., erect, tortuous: leaves oval, rough on the upper side, toothed: flowers malodorous, in lateral compound racemes: bark wrinkled and cracked.

Curmeria

: Homalomena.

Cuscuta

(origin of name obscure). Convolvulaceae. Dodder. Degenerate parasitic twiners, bearing clusters of small flowers. They are leafless annuals, with very slender yellow, white, or red stems, which become attached to the host-plant by means of root-like suckers. The seeds fall to the ground and germinate in the spring. - Species 100, widely distributed. As soon as the young shoot reaches an acceptable host, the root dies and the plant becomes parasitic. Failing to find a host, the plant dies. Dodders are common in low, weedy places. Some species are also serious pests, as the clover dodder, alfalfa dodder, and flax dodder. One of the common species (C Gronovii, Willd.), of low grounds, is shown in Fig. 1158.

Cyanella

(from the blue color). Amaryllidaceae; it has been referred to Liliaceae and also to Haemo-doraceae. A half-dozen or less small bulbs from S. Africa, sometimes grown in the way of ixias. Plants with rhizomes or tunicate corms, radical or basal lanceolate or linear leaves, and simple or rarely branched stems: flowers violet, rose, yellow or white, solitary or racemed-paniculate; perianth-tube 0, the segments distinct or very nearly so; stamens 6, attached to base of segments, all perfect, often dimorphous- fruit a loculicidal 3-angled caps., on bractless pedicel. The cyanellas are summer- and fall-flowering bulbs with us. The following are the kinds likely to be found: C. capensis, Linn. Leaves lanceolate, undulate: stem panicled, leafy, 1 ft.: flower purple. B.M. 568. C. 1utea, Linn. f. (C. odoratissima, Lindl.). Less branched: leaves linear-lanceolate, acuminate, not undulate: flowers rose, changing to yellow. B.R. 1111. L. H. B.
