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

 GleicheniAcea. A genus of about 30 species of ferns 

 from the tropical and south temperate zones, growing 

 naturally in dense thickets. The leaves fork, often 

 several times, and the family is characterized by dorsal 

 sori composed of a few neiirly scs.sile spurnn^ia; these 

 are surrounded by a brn:,.! irm \i r i liiiL,'. nml open 

 vertically. The species :<<•■• '■ •'■• "• '-.'l :ii. ^iftrn cata-

A. Ultimate lobes small, roundish. 

 B. Sonts of S-4 sporangia, superficial. 



rupfistris, 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, witti the ra- 

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

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



Var. speliincse, Hort. {O. speUncK, R.Br.). Lvs. pen- 

 dent but not curving ; pinnules curved inward, form- 

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

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

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

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

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

 BB. Sortis of 2 sporangia concealed in slipper-shaped 

 lobes. 



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

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

 face rusty-hairy. Australia. 

 AA. Ultimate lobes pectinate : sori near the middle of

glailca, 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. 



{labell&ta, R. Br. Lvs. 2-3 times forked, the divisions 

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

 mate divisions linear. Australia.

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

 dich6toma, Willd. With a distinct pair of pinnce 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 

 widely distributed species. ^ jj Usdeewood. 



GLOBBA (Malayan name). Scilamindcece. This ge- 

 nus, which lielongs 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 strufrnre. Only one species is known to 

 be cult, in AmiTir:i. 'riii^ is kn.ovn to the trade as

 G.C.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 

 with G. atrosanquinea. This plant was highly praised 

 in 1893 by John Saul, who said substantially; "Plants in 

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

 12-18 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. V. II. 18:407 Burbidge gives the honorto 

 Curtis. For culture, see Alpinia.

 offsets may be removed (when they occur J and grown

 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, thev may be grown permanently in the open. 

 Success with Gloriosa depends on having strong bulbs.
