Naegelia (Karl von Naegeli, once professor of botany at Munich). Gesneriaceae. Trop. American herbs allied to Achimenes. but the fls. arranged alternately in a leafless terminal panicle (in Achimenes the fls. are axillary). In cult., the plants are oftener called gesnerias than naegelias, but they are distinguished from that genus in usually having an annular or ring-like disk at the base of the corolla, rather than a deeply lobed disk. Tubers usually none, the plant rhizomatous or repent: st. nearly simple: lvs. opposite, soft long petioled, usually cordate: fls. showy, mostly red, sometimes yellowish white or suffused, alternate in a terminal cluster with very small bracts at base of pedicels; corolla declined or hanging, oblique and usually more or less spotted in throat, much exceeding calyx.—Species about a half-dozen, Mex. and Cent. Amer. Naegelias hybridize with other gesnerias. One hybrid race is known as Naegelio-Achimenes and another (F.S. 10: 987, 988) as Mandirola. Because of the panicled fls., naegelias are very ornamental plants. They are warm- house subjects, prop. by stolons or offsets. Because of conflict with another genus of the same name, Kuntze proposes the name Smithiantha for this genus; but the way seems to be clear for the use of the well-established Naegelia. See Smithiantha. In general, the cultural methods given under Achimenes (Volume I, page 206) suit naegelias well (compare also Gloxinia). The roots should be stored in the pots in which they have been grown. It is a poor plan to keep any bulbs or tubers of the Gesneriaceae; in dry sand in a dry storeroom. After being well ripened, naegelia roots should be kept in the greenhouse under the benches. Keep them out of the drip, but water them occasionally. N.fulgida.Ort. Fls. vermilion: lvs. large, oval, deeply toothed. Mex.— N Geroltiana, Regel (Smithiantha Geroltiana, Kuntze). Continuous- flowering plant, allied to N. sebrina. Mex. F.S. 2:97. — N sceptre corail, Carr. Fls. many in an open panicle, cinnabar-red, yellow- spotted inside. R.H. 1869,p. 154 and col. pl. For pictures of varieties and hybrids, see F. S. 16:1671- 1672; 10:987-988. The above text is from the Standard Cyclopedia of Horticulture.
