 GLEICHfiNIA (W. P. Von Gleiclien. 1717-1783). 

 Gleic)ie)ii(tce<T. A genus of about 30 species of ferns 

 from the tropical auil south temperate zones, growing 

 naturally iu dense thickets. The leaves fork, often 

 several times, and the family is characterized by dorsal 

 sori composed of a few nearly sessile sporangia ; these 

 are surrounded by a broad transverse ring, and open 

 vertically. The species after the third are often cata- 

 logued under Mertensia, aname which, because used for 

 a genus of Howers, must give way to Dicranopteris if 

 they are separated and placed in a distinct genus, where 

 they probably belong. 



A. Ultimate lobi'S smalt, rouiidisli. 

 B. Sorus of S-i sporangia, superficial. 



rnp6stris, R. Br. Lobes rounded or obtusely quad- 

 rangular, the margins thickened and recurved, some- 

 what glaucous beneath. Australia. Var. glauc^scens, 

 Moore, has Ivs. of thicker texture, which, when young, 

 are very glaucous on both sides, contrasting with the 

 reddish purple stalks. 



circinita, Swz. Lobes ovate or rotund, with the ra- 

 chides pubescent when young ; 3-5 times forking, the 

 ultimate pinnules 1 in. long. Austral., New Zealand. 



Var. speliincae, Hort. {G. speliuirce. R.Br.). Lvs. pen- 

 dent but not curving ; pinnules curveil inward, form- 

 ing small cavities. Var. semivestita, Lal)ill. (G. senii- 

 restlta, Hort.), differs in its close and very erect habit, 

 and flat, deep green piunEe. Var. M^ndelli, Moore (G. 

 MindeUi, Hort.). More robust and compact than the 

 type, with flat, thicker and glatioous lvs. Gn. 51, p. 472. 



BB. Sorus of J sporangia concealed in slipp.'r-shajH'd 

 lohcs. 

 dic4rpa, R.Br. Lvs. 2-4 times forked, with the lobes 

 strongly arched, rotund or narrow, with the under sur- 

 face rusty-hairy. Australia. 



AA. intimate lohes pectinate : sori near the middle of 



the rei)ilets. 



c. Leaf, after first forlang, hipinnate. 



glailca, Hook. Primary branches elongate, 2-3 ft. in 



length ; rachises with rtisty scales ; piunie 4-8 in. long, 



with closely placed entire segments, glaucous beneath. 



China and Japan. 



cc. Leaf with fan-sltaped divisions. 



flabellata, R. Br. Lvs. 2-3 times forked, the divisions 

 ascending, 6 in. or more long, elliptic-lanceolate ; ulti- 

 mate divisions linear. Australia. 



longipinnata, Hook. Branches of the lvs. repeatedly 

 dichotomous ; pinna? up to 2 ft. long, 3 in. wide. Trop. 

 America. 



AAA. LTltimate brayiches with a pair of forked pinner: 

 leaf stems zigzag, repeatedly dichotomous. 



dicll6toma, Willd. "With a distinct piair of pinnie aris- 

 ing from the base of the forked branches ; segments 

 not decurrent. Tropical regions generally, but several 

 species have been confused here, as in manv of the 

 widely distributed species. l. M. Underwood. 



GL6BBA (JIalayan name). Sdhnnindee^p. This ge- 

 nus, which belongs to the same family with the cannas 

 and ginger plant, contains some herbaceous conserva- 

 tory plants with rhizomes and habit of canna, and a 

 singular floral structure. Only one species is known to 

 be cult, in America. This is known to the trade as 

 G. coccinea, which is really G. atrosangui>iea , figured 

 at B.M. 6626. Index Kewensis is clearly in error iu re- 

 ferring G. coccinea to G. nlbo-hracteata, as is plain from 

 G.C. li. 18:71. Veitch introduced in 1881 a plant under 

 the provisional name of G. coccinea, as it was supposed 

 to be a new species, but the next year it was identified 

 with G. atrosangninea . This plant was highly piraised 

 in 1893 by -John Saul, who said substantially: "Plants in 

 bloom the greater part of the year: stems much crowded, 

 12-18 iu. long, gracefully arching on all sides: tis. scar- 

 let and vellow, in dense racemes." The credit for the

discovery of this plant is generally given to P. W. Bur- 

 bidge, but in G. ('. 11. 18:407 Burbidge gives the honor to 

 Curtis. Por culture, see Atpinia. 



atrosangTiinea.Tei.ism. & Binnend.((?. coco (iifn, Hort., 

 Veitch). Stem slender, becoming 2-3 ft. high: Ivs. 

 3-4 in. long, elliptic, acuminate at both ends; sheaths 

 purplish, pubescent, closely clasping the stem: lower 

 Howerless bracts di.stant, brown, 6-9 lines long: upper 

 and flowering bracts crowded, red : fls. \% in. long; 

 corolla yellow, tubular, thrice as long as calyx. Borneo.

GLOBULAKIA (the flowers in small, globular heads). 

 GJohulariAcew. Aliout a dozen species of Old World 

 herbs, subshrubs aud shrubs, with small blue fls. mostly 

 in glolmlar heads. Lvs. from the root, or alternate, 

 leathery, entire or with a few sharp teeth. Probably the 

 commonest and best species is G. trico.satifha. which 

 thrives at the front of well-drained borders, but is par- 

 ticularly showy in the rockery. For this and G. vulgaris 

 aud its forms, J. B. Keller advises rather moist but 

 well-drained soil and partial sha<le. Prop, by division 

 or seed.

GLORlOSA (Latin for (jJorious). Syn., Methonica. 

 Lilid-Cnr. Three tropical species, all African, and one 

 also Asian. They are tall, weak-stemmed plants, sup- 

 porting themselves by means of tendril-like prolonga- 

 tions of the alternate, lanceolate or lance-ovate lvs. : fls. 

 many and showy, long-stalked, borne singly in the axils 

 of the upper lvs. ; perianth of 6 distinct long segments, 

 which are undulate or crisped, and reflexed after the 

 manner of a Cyclamen, variously colored; stamens 6, 

 long and spreading, with versatile anthers: ovary 3- 

 loculed ; style long, and bent upward near the base. 

 Odd and handsome plants, to be grown in a warm house. 

 They are not diflicult to grow. The brightest fls. are 

 produced in sunlight. The plants grow from tubers. 

 These tubers should be rested in early winter, and 

 started in pots in January to March. The plants bloom 

 in summer and fall. When potting the old tubers. 

 offsets may be removed {when they occur) and grown 

 separately for the production of new plants. The tubers 

 may be cut in two for purposes of propagation. Let the 

 plants stand near a pillar or other support. Give freely 

 of water when the plants are growing. In this country 

 they are sometimes bedded out in summer. W. E. Endi- 

 cott cultivates Gloriosa outdoors in summer at Canton, 

 Mass., and fi.nds that the plants so treated are not much 

 inclined to climb and flower as freely as under glass. 

 In Florida, they may be grown permanently in the open. 

 Success with Gloriosa depends on having strong bulbs.
