GLEICHENIA (W. F. Von Gleichen, 1717-1783). 

 "leiclieniacece. A genus of about 30 species of ferns 

 ; rom the tropical and south temperate zones, growing 

 latumlly in dense thickets. The leaves fork, often 

 several times, and the family is characterized by dorsal 

 I ?ori composed of a few nearly sessile sporangia; these 

 ire surrounded by a broad transverse ring, and open 

 Vertically. The species after the third are often cata- 

 ogued under Mertensia, a name which, because used for 

 i genus of flowers, must give way to Dicranopteris if 

 : ;hey are separated and placed in a distinct genus, where 

 ;hey probably belong. 



A. Ultimate lobes small, roundish, 

 B. Sorus of 3-4 sporangia, superficial. 



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

 rangular, the margins thickened and recurved, some- 

 what glaucous beneath. Australia. Var. glaucescens, 

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

 are very glaucous on both sides, contrasting with the 

 reddish purple stalks. 



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

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

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



Var. speluncae, Hort. (G. spehlncce, R.Br. ). Lvs. pen- 

 dent but not curving ; pinnules curved inward, form- 

 ing small cavities. Var. semivestita, Labill. ( G. semi- 

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

 and flat, deep green pinnae. Var. Mendelli, Moore (G. 

 Me'ndelli, Hort.). More robust and compact than the 

 type, with flat, thicker and glaucous Ivs. Gn. 51, p. 472. 



BB. Sorus of 2 sporangia concealed in slipper-shaped 



lobes. 



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

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

 'face rusty-hairy. Australia. 



AA. L r ltimate lobes pectinate : sori near the middle of 



the veinlets. 



c. Leaf, after first forking, bipinnate. 

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

 length ; rachises with rusty scales ; pinnae 4-8 in. long, 

 with closely placed entire segments, glaucous beneath. 

 China and Japan. 



cc. Leaf with fan-shaped 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 Ivs. repeatedly 

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

 Ame- ica. 

 AAA Ultimate branches with a pair of forked pinnae : 



leaf stems zigzag, repeatedly dichotomous. 

 dich6toma, Willd. With a distinct pair of pinnae aris- 

 ing from the base of the forked branches ; segments 

 not decurrent. Tropical regions generally, but several 

 species have been confused here, as in many of the 

 r distributed species. L M UNDERWOOD . 



GLOBE A (Malayan name). Scitaminacece . 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. atrosangiiinea, figured 

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

 ferring G. coccinea to G. albo-bracfeata, as is plain from 

 II. 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 

 kh G. atrosanguinea. This plant was highly praised 

 >3 by John Saul, who said substantially: "Plants in 

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

 18 in. long, gracefully arching on all sides: fls. scar- 

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



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

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

 Curtis. For culture, see Alpinia. 



atrosanguinea, Teijsm. & Binnend.(. coccinea, 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 

 flowerless bracts distant, brown, 6-9 lines long: upper 

 and flowering bracts crowded, red : fls. 1% in. long ; 

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

GLOBTJLABIA (the flowers in small, globular heads). 

 Globulariaceoz. About a dozen species of Old World 

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

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

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

 commonest and best species is G. tricosantha, which 

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

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

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

 well-drained soil and partial shade. Prop, by division 

 or seed. 



A. Hardy herbaceous plants about 6-12 in. high. 



B. Root-lvs. 1-nerved. 



trichosantha, Fisch. & Mey. Height 6 in. : root-lvs. 

 spatulate, 3-toothed at apex; stem-lvs. obovate or oblong, 

 mucronate, sessile. July, Aug. Asia Minor. Syria. 

 "Lvs. turn blackish purple in fall." Woolson. 



BB. Root-lvs. 5-nerved. 



vulgaris, Linn. Height 8-12 in.: root Ivs. obovate, 

 petiolate, nearly entire, apex entire, notched or mucro- 

 nate: stem-lvs. lanceolate, sessile. S. Eu., Caucasus. 

 July, A*ug. B.M. 2256. 



A A. Tender subshrub. 



Alypum, Linn. Lvs. obovate-oblong, mucronate or 

 3-toothed at apex. Mediterranean regions. Cult, in S. 

 Calif, by Franceschi, who says it is covered with fls. all 

 winter. Also cult, abroad under glass. "\y. j^ 



GLORIOSA (Latin for glorious). Syn., Methdnica. 

 Liliacece. 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 Ivs. : fls. 

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

 of the upper Ivs.; 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 difficult 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 finds 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.
