 GLOEY OF THE SNOW. Fanciful name for CJiioiio- 



GL0XIN|;RA. Name given to hybrids of Gloxinia 

 (Sinningia) and Gesneria. See Gloxinia. 



GLOXINIA. The genus Gloxinia was founded by 

 L'Heritierin 1785(named in honor of P. B. Gloxin, a bota- 

 nist of Strassburg) upon G. maculata of Brazil. Early 

 in this century a related Brazilian plant was introduced, 

 and it attracted much attention: this plant was named 

 Gloxinia speciosa by Loddiges in his Botanical Cabinet 

 in 1817, and it was there figured. In the same year it 

 was figured by Ker in the Botanical Register, and 

 also by Sims in the Botanical Magazine. Sims wrote 

 that the plant was ":iln;idy to be found in most of 

 the large collccti.iiis ^il.nut ti.wn [London]." These 

 writers refer thi- iilant t.. tin- Linniean class Didynamia, 

 but Ker also suf,'t;..sts tli:it it may belong to the Cam- 

 panulacese. This Gloj-inin siurh.^n wn-^ the fi.rirmiiirr 

 and leading parent of thi- ^'ar^.n ' .I-m- - i- , i ,,.i - . i,,, i 

 are now referred to the fajnily 1 .r' 

 out that the plant really lirlMims i ~. ... 

 gia, founded in 1825 on a Ura/.ili.m ilani w In.li In 

 named S. Helleri. All our garden Gloxinias are Sin- 

 ningias, but to gardeners they will ever be knomi as 

 Gloxinia; therefore, we will trace the evolution of them 

 here. The genus is one of the Gesneracece. 



Gloxinia has no tubers: Sinningia has. Gloxinia has 

 a ring-like or annular disk about the ovary: Sinningia 

 has 5 distinct glands. The Sinningias are either stem- 

 less or stem-bearing, with a trumpet-shape or bell-shape 

 5-lobed and more or less 2-lipped corolla, a 5-angled or 

 5-winged calyx, 4 stamens attached to the base of the 

 corolla, and with anthers cohering at the tips in pairs, 

 and a single style with a concave or 2-lobed stigma. 

 The garden Gloxinias belong to the subgenus Liggria 

 (subgenus of Sinningia), which has a short stem or 

 trunk, and a broad-limbed bell-shaped flower. 



The true Gloxinias are not florists' flowers, and they 

 are little known in cultivation. They are apparently not 

 in the American trade. The old G. maculata is figured in 

 the Garden 39:801 (p. 3G4),and it is probably to be 

 found in choice collections in the Old World. It pro- 

 duces knotty rootstocks, which, as well as the leaves, 

 may be used for propagation. It is also figured in B.M. 

 1191. G. glabrdta, Zucc, from Mex., is the G. glabra, 

 Hort., Achimenes gloxiniceflora, Forkel, and Plectopoma 

 gloxiniflorum, Haust. It is a stemmy plant, with white 

 fls. with yellow-spotted throat. (B.M. 4430, as G. fimiri- 

 ata,K0Tt.) Plectopoma is now referred to Gloxinia. A 

 few forms of this were once offered by Saul, but, with 

 the exception of P. gloxiniflorum, they are probably all 

 garden forms. 



The garden Gloxinias (genus Sinningia) are nearly 

 stemless plants, producing several or many very showy 

 bell-like fls. each on a long stem. Gloxinia speciosa 

 originally had drooping fls., but the result of continued 

 breeding has produced a race with fls. nearly or quite 

 erect (Pigs. 918, 919). The deep bell of the Gloxinia 

 is very rich and beautiful, and the erect position is 

 a decided gain. The fls. also have been increased in 

 size and number, and varied in shape and markings ;

part of the evolution in the common greenhouse Glox-

 but hybridity has played an important part. One of the

 II' ' ii'.t of the S. guttata, except a distinct branching 

 liahu in some of the plants (B.R. 30:48). It is possible, 

 however, that S. gititata has had something to do with 

 the evolution of the spots on the present-day flower,

There are double forms of Gloxinia, in which an outer 

 but shorter corolla is formed. These forms are more curi- 

 ous than useful. Gloxinia (Sinningia) has been hybri- 

 dized with Ge.sneria; and the hybrid progeny has been 

 called Gloxinera (G.C. 111. 17:145, Pig. 22). l. h. B. 



Gloxinias are general favorites with most people. 

 Their large tubular and richly colored blossoms, to- 

 gether with their soft, velvety green leaves, make a 

 gorgeous display when in flower. Being natives of tropi- 

 cal America, they require stove temperature during their 

 growing season. Though they may be grown so as to 

 flower at almost any season of the year, yet they are 

 naturally summer-flowering plants, and do best when 

 treated "as such. They are propagated by seeds, or by 

 cuttings made of leaves or stems. Seeds are preferable, 

 unless one wishes to increase some very choice colored 

 variety, when it is best to propagate by leaf cuttings,
