NAEGELIA (Karl von Naegeli, once professor of bot- 

 any at Munich). Gesneridcese. 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 ges- 

 nerias 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 : Ivs. opposite, soft, long- 

 petioled, usually cordate: fls. showy, mostly red, some- 

 times yellowish white or suffused, alternate in a ter- 

 minal 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 Achim- 

 enes (Volume I, page 206) suit naegelias well (com- 

 pare 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 Gesneriaceas 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. (T. D. Hatfield.) 



A. Fls. nearly scarlet, or brick-red, marked with white. 



cinnabarina, Lind. (Gesneria cinnabarina, Lind. 

 Smithiantha cinnabarina, Kuntze). Fine winter-bloom- 

 ing plant, 1H~2 ft. tall, soft-hairy: Ivs. 

 round-ovate and cordate, crenate-dentate, 

 thickish, green, with red or purplish hairs: 

 fls. about \ l /2 in. long, hanging on the ends 

 of spreading pedicels, gibbous-tubular to 

 the very base, the calyx-lobes acute and 

 spreading, the short corolla-lobes unequal 

 and obtuse, the fl. cinnabar-red or nearly scarlet on the 

 upper side, but paler and spotted on the under side. 

 Mex. B.M. 5036. Lowe, 33. H.F. II. 5:4 (var. 



AA. F Is. orange-scarlet or scarlet, marked with yellow. 



zebrina, Regel (Gesneria zebrina, Paxt. Smithidntha 

 zebrina, Kuntze). Fig. 2429. Much like the above, but 

 brighter colored, red-dotted below and yellow within 

 and on the under side: calyx-lobes short and appressed; 

 corolla contracted toward the base, whereas they are 

 gibbous or swollen to the very base in N. cinnabarina. 

 Brazil. B.M. 3940. B.R. 28:16. P.M. 8:271. A fine 

 plant, of which there are several forms. The common- 

 est species. Names belonging here are Gesneria regalis 

 and G. splendens. 



achimenoides, Bart. (Smithidntha achimenoides, 

 Fritsch). Hybrid of N. zebrina and Achimenes or 

 Gloxinia (said to be with A. glabrata; see Gloxinia, Vol. 

 Ill, p. 1350): fls. very large (often 2 in. long), yellow- 

 ish rose on the outside, yellow and rose-spotted on the 

 inside, the segms. clear rose. 



AAA. Fls. white, cream-color or rose. 



multiflora, Hook. (N. amdbilis, Decne. Smithidntha 

 amdbilis, Kuntze. Gesneria amdbilis, Hort.). Fls. white 

 or cream-color, numerous, hanging, the tube curved and 

 not much swollen, the obtuse lobes subequal: plant 

 bearing long, glandular hairs in addition to the velvety 

 covering: otherwise much like N. zebrina. Mex. B.M. 

 5083. F.S. 12:1192 (as Achimenes [Naegelia] amabilis). 

 G.C. III. 22:413. Gn. W. 23:335. G. 22:631. The 

 tenable name of this species is sometimes held to be 

 Decaisne's AT. amabilis, which goes back to 1857, but 

 Gloxinia multiflora, Mart. & Gal., dates from 1842. 



hyacinthina, Carr. Of horticultural origin, probably 



a hybrid : fls. white 

 or rose, in a very 

 compact pyram- 

 idal panicle. R.H. 

 1877, p. 29. 



N.fulgida,Ort. Fls. 

 vermilion: Ivs. large, 

 oval, deeply toothed. 

 Mex. N. Geroltiana, 

 Regel (Smithiantha 

 Geroltiana, Kuntze). 

 Continuous- flowering 

 plant, allied to N. 

 zebrina. Mex. F.S. 

 2:97. N. sceptre co- 

 rail, Carr. Fls. many 

 in an open panicle, 

 cinnabar-red, yellow- 

 spotted inside. R.H. 

 1869, p. 154 and col. 

 pi. For pictures of

 tat of the first-
