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

 Gleicheniaccae. Ferns mainly from the tropical and south 

 temperate zones, growing naturally in dense thickets; 

 one species has recently been found in Louisiana, D. 

 flcxuosa. (Amer. Fern Jour. 4:15). 



The family is characterized by dorsal sori composed 

 of a few nearly sessile sporangia; each sporangium is 

 surrounded by a broad transverse ring, and opens 

 vertically. The most striking thing about the family 

 is the growth of the lvs. The lvs. of many of the species 

 are perennial and show an indeterminate growth. Dur- 

 ing the growing season, the end of the If. will keep 

 unrolUng after the usual manner of ferns. During the 

 resting season this tip rests, but resumes its growth the 

 next season. The lvs. of some species may thus become 

 over 100 ft. in length. The species after the third (aa) 

 are often catalogued under Mertcnsia, a name which, 

 because used for a genus of flowers, must give way to 

 Dicranopteris if they are separated and placed in a dis- 

 tinct genus, where they probably belong. 



A. Ultimale 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. Austral. Var. glaucescens, 

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

 are very glaucous on both sides, contrasting with the 

 reddish purple stalks. 



circinata, Swartz. Lobes ovate or rotund, with the 

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

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



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

 dent but not curving; pinnules curved inward, form- 

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

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

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

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

 type, with flat, thicker and glaucous lvs. 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 strongly arched, rotund or narrow, with the 

 under surface rusty-hairy. Austral. 



AA. Ullimate lobes pectinate: sori near the middle of 

 the veitdets. 



B. Lf. after first forking, bipinnate. 



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

 long: rachises with rusty scales; pinna; 4-8 in. long, 

 with closely placed entire segms., glaucous beneath. 

 China and Japan. 



BE. Lf. 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. Austral. 



longipinnata, Hook. Branches of the lvs. repeatedly 

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

 Amer. 



AAA. Ultimate branches with a pair of forked pinnse: 

 If.-sts. zigzag, repeatedly dichotomous. 



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

 ing from the base of the forked branches; segms. not 

 decurrent. Tropical regions generally, but several 

 species have been confused here, as in many of the 

 widely distributed species. l, jyj Underwood. 



R. C. BENEDICT.f 



GLIRICIDIA {rodent-poison, from the seeds). Legumi- 

 nosse. Eight or 10 woody plants, Cuba and Mex., to 

 S. Amer., differing from Robinia in the wingless or 

 marginless pods and coriaceous valves. Lvs. odd-pin- 

 nate, the Ifts. entire: fls. rose-colored, racemose or 

 fasciculate; calyx-teeth short and broad, the 2 upper 

 ones joined; standard large, reflexed; wings falcate- 

 oblong; keel incurved, obtuse; ovary stipitate, manj'- 

 ovuled, becoming a broad-linear 2-valved pod. 

 G. platycarpa, Griseb., of Cuba, is offered in 8. Fla.: 

 tree, to 25 ft.: Ifts. 7-9, ovate or ovate-oblong, glabrous, 

 the margins undulate: corolla pink or purplish; stigma 

 ciliate: pod sessile, piano-compressed, lanceolate-oblong, 

 8-seeded. G. maculata. HBK. (Lonchocdrpus macida- 

 tus, DC), Guatemala to S. Amer., is reported as in 

 cult, in S. Fla.: small tree: Ifts. about 17, oblong, obtuse, 

 somewhat appressed-pilose above and blackish-spotted 

 and glaucescent beneath: pod Knear, compressed, with 

 thickened margin. l jj g 



GLOBBA (Malayan name). Zingiberaceie. Herba- 

 ceous conservatory plants with rhizomes and habit of 

 canna, and a singular floral structure. 



Flowers in terminal panicles; bracts usually decidu- 

 ous; calyx funnel-shaped, 3-lobed; corolla-tube longer 

 than the calyx, the lobes nearly equal, ovate; stami- 

 noid petal-hke and fastened to the corolla-lobes; ovary 

 1-celled, forming a globose, tardily dehiscing caps. — 

 Only one species is known to be cult, in .^mer. This is 

 known as G. coccinea, which is really G. atrosanguinea, 

 figured at B.M. 6626. "Index Kewensis" is clearly in 

 error in referring G. coccinea to G. atbo-bracteata, as is 

 plain from G.C. H. 18:71. Veitch intro. 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. atrosanguinea. This plant was 

 highly praised in 1893: "Plants in bloom the greater 

 part of the year: sts. much crowded, 12-18 in. long, 

 gracefully arching on all sides: fls. scarlet and yellow, 

 in dense racemes." The credit for the discovery of this 

 plant is generally given to F. W. Burbidge, but in G.C. 

 II. 18:407, Burbidge gives the honor to Curtis. For 

 cult., see Alpinia. 



atrosanguinea, Teijsm. & Binn. (G. coccinea, Hort., 

 Veitch). St. slender, becoming 2-3 ft. high: lvs. 3-4 

 in. long, elliptic, acuminate at both ends; sheaths 

 purplish, pubescent, closely clasping the st.; lower 

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

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

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

 small blue flowers mostly in spherical heads. 



Leaves from the root or alternate, leathery, entire 

 or with a few sharp teeth: fls. small, blue, in dense
