this country, as an ornamental tree. It 

 grows from fifty to eighty feet high, send- 

 ing forth large spreading branches, and 

 while young both stem and branches are 

 formidably armed with stout, usually tri- 

 ple, thorns, tapering to very sharp points ; 

 but as the tree increases in size these 

 thorns are principally confined to the 

 smaller branches. In the autumn the trees 

 bear numerous long thin and fiat pendu- 

 lous pods, which are usually curved and 

 often twisted, and have been compared 

 to ' large apple-parings, pendent from the 

 branches.' They are sometimes as much 

 as a foot and a half long, and contain 

 numerous seeds, enveloped in a sweet pulpy 

 substance, from which a kind of sugar 

 is said to have been extracted. The wood 

 is coarse-grained, very hard, and splits 

 easily, but is not much employed except 

 for fences and similar purposes. G. mono- 

 sperma, the Water-locust of the Southern 

 United States, is a very large tree, closely 

 resembling the last in general appearance, 

 but its flat pods are small and nearly oval, 

 and contain only one seed. [A. S.] 



GLEICHENIACE2E. A group or sub- 

 order of Ferns, remarkably distinct in as- 

 pect from other ferns. They belong to the 

 long series which is distinguished by the 

 spore-cases having a jointed ring, and 

 bursting irregularly instead of being val- 

 vate ; but the spore-cases are sessile, and 

 the ring is more or less strictly horizontal, 

 and consequently the fissure made by their 

 bursting takes a vertical instead of the 

 more usual horizontal direction. The ad- 

 ditional features of rigid opaque fronds 

 and oligocarpous dorsal sori complete the 

 distinctive marks of the group, of which 

 Gleichenia is the principal genus. [T. M.] 



GLEICHENIA. A genus of polypodia- 

 ceous Perns, typical of the tribe Gleiche- 

 nineai. They are furnished with creeping 

 rhizomes, rigid usually often repeatedly 

 dichotomously forked fronds, with the 

 ultimate branches pinnatifld, and either 

 bearing small rounded or ovate segments, 

 or larger linear ones resembling the teeth 

 of a comb. The sori are naked, sometimes 

 placed in a hollow space, oligocarpous, | 

 that is, consisting of but few spore-cases, ! 

 the number varying from two to four in 

 one group, and from eight to twelve in 

 another. The latter series, which agrees | 

 with that having the linear segments, 

 forms the group Mertensia, which some 

 pteridologists regard as a distinct genus, j 

 There are many species scattered widely 

 in the tropics both of the Old and New 

 World, and extending to Chili and the ! 

 Australasian region. [T. M.] I 



GLI. An intoxicating liquor prepared \ 

 by the Hottentots from Lichtensteinia 

 pyrethrift'lia. 



GLIDEWORT. Galeopsis Tetrahit. 



GLINUS. A genus usually referred to He- 

 sembriiacece, but considered by A. Richard, 

 Endlicher, and others, as belonging to the 

 Caryophyllacece, tribe Molluginece. They are 



annual prostrate branched herbs, rarely 

 undershrubs, growing in tropical and sub- 

 tropical regions, a single species occurring 

 in the south of Europe. Leaves alternate 

 or falsely verticillate ; flowers inconspicu- 

 ous, with a five-cleft calyx; the corolla 

 absent, or with numerous very narrow 

 strap-shaped petals, and three to twenty 

 stamens. [j. t. S.] 



GLOBBA. A genus of tropical Asiatic 

 herbaceous plants belonging to the Zingi- 

 beracew, and having a terminal loosely- 

 clustered inflorescence, the flowers of 

 which have a three-cleft tubular calyx; a 

 corolla with a slender tube and a six-parted 

 limb, the three outer divisions equal, and 

 two of the inner ones narrow or very 

 small, while the remaining one, or lip, is 

 large, undivided, and partly united with 

 the filament in a tubular manner. The 

 ovary is one-celled. They are handsome 

 plants, with singular-looking yellow or 

 pinkish flowers ; some of them grown in 

 this country as stove plants. The fruit of 

 G. uviformis is said to be edible. [M. T. MJ 



GLOBE-FLOWER. Trollius ; also Gom- 

 phrena globosa. 



GLOBOSE. Forming nearly a true sphere. 



GLOBULAIRE. (Fr.) Gldbulariavulgaris. 



GLOBULARIACE.E. A natural order 

 of corollifloral dicotyledons, belonging to 

 Lindley's echial alliance of perigynous 

 Exogens. Lindley unites Selaginacece with 

 this order, but De Candolle separates them. 

 A small group of herbaceous or shrubby 

 plants with alternate exstipulate smooth 

 leaves, and capitate flowers surrounded by 

 an involucre. Calyx five-divided with yuin- 

 cuncial estivation ; corolla tubular, lipped, 

 five-lobed ; stamens four, inserted into the 

 upper part of the tube of the corolla, the 

 anther becoming one-celled, and opening 

 by a single longitudinal slit. Ovary free, 

 one-celled; ovule one, pendulous anatro- 

 pal. Fruit an achene, enclosed by the 

 calyx ; seed with fleshy albumen ; embryo 

 with a superior radicle. Natives of Europe, 

 and of the parts of Asia and Africa nearest 

 Europe. There are but few species, dis- 

 tributed in the genera Carracloria and 

 Globularia. [J. H. B.] 



GLOBULARIA. A genus containing 

 a few species of herbs, shrubs, or under- 

 shrubs, natives of the countries bordering 

 on the Mediterranean Sea. They have 

 alternate entire spathulate leaves, and flow- 

 ers collected upon a common receptacle, 

 and surrounded by a many-leaved involu- 

 cre. The calyx is unequally five-cleft ; the 

 corolla tubular, with the limb two-lipped, 

 the upper lip bipartite and smaller than 

 the lower, which is trifld; and there are 

 four stamens, inserted at the top of the 

 corolla tube. The ovary is composed of a 

 single carpel, and contains a single pen- 

 dulous anatropal ovule. This genus differs 

 from the Selaginacece, in having the ovary 

 formed of a single carpel, as well as in its 

 habit, in both of which respects it agrees
