weeks old by inarching to strong-lowing plants of 

 other species of the same genus or in some cases on 

 species of other genera of the same family. This has 

 been clone recentlj' with such plants as chestnuts, wal- 

 nuts, hawthorns, oalcs, and many others. It is not 

 necessarily done for the purpose of hastening the 

 flowering or the fruiting of new plants, but to give 

 quickly an abundance of material for propagation by 

 budding or grafting when the new material is assumed 

 to be valuable. If a hardwood seedhng of hybrid origin 

 is tied to a large stock and they fail to unite, there is 

 httle or no danger of losing the seedling, provided its 

 roots are kept damp during the period of making the 

 attempt. If the inarch is not successful, the seedling 

 can be repotted and grown in the usual way." 



In Fig. 1703 is shown the method of seedling-inarch.

been pricked off into a 2-inch pot shortly after the 

 cotyledons are developed; it is next shown, after two 

 or three weeks' growth, removed from the pot and tied 

 in a cloth to facihtate handUng, a httle fresh soil being 

 held in place by the covering; the ball is then .secured 

 to the stock, and the seedhng is inarched by chamfering 

 the surfaces in contact. When union is complete, the 

 root of the seedling is removed.

For further discussion of the whole subject of graft- 

 ing, the reader is referred to current works on fruit- 

 growing; also to the two American special books on 

 the subject — FuUer's "Propagation of Plants" and 

 Bailey's "Xursery-Book." In Enghsh, Baltet's "Bud- 

 ding and Grafting" is standard. It is an Enghsh version 

 of "L'Art de Greffer." L. H. B. 



GRAHAMIA (Robert Graham, Scotch botanist, died 

 184.5). Two genera have been made of this name. The 

 accepted one is of the Portulacacea', comprising one 

 species (G. brncteaia, Gill.) of extra-tropical South 

 America; this plant is not recorded in cultivation. The 

 other Grahamia (of Sprengel) is now referred to 

 Cephalophora; and Cephalophora is by Hoffmann 

 (Engler & Prantl, PP.anzenfamilien, iv:.5J included in 

 Helcnium. Of this Grahamia, G. aromatica is offered 

 abroad ; it is accounted for under Hehnium. 



GRAMMANGIS (Greek, gramma; perhaps referring 

 to the markings of the flowers). Orchidaceee, tribe 

 Vdnd(x. Epiphytic orchids grown in greenhouses. 



Pseudobulbs short and thick, with foliage-lvs. only 

 at their summit, hence not inclosed in the If .-sheaths: 

 fl.-clusters from the ba.se, many-fid., pendulous; fls. 

 not spurred; middle sepals strongly concave, lateral 

 sepals somewhat sac-shaped at base, free, spreading; 



Eetals ascending, somewhat different in form and color; 

 p 3-lobed, with erect lateral lobes and recurved middle 



lobe; column slender, winged. — Species about 4, of 

 Madagascar and Java. Nearest CjTnbidium, differ- 

 ing chiefly in having the foliage-lvs. only at the end of 

 the pseudobulb, and the rostellum crescent-shaped (in 

 Cymbidium it is triangular). From Grammatophyllum 

 (which see), Grammaugis differs in the attachment of 

 its pollen-masses and in the position of its foliage-lvs. 

 Best cult, in- baskets hung near the glass, where the 

 hght is most intense. The plants can also be grown 

 successfully in pots placed near the glass, or fastened 

 to blocks, but in the latter case they must be given more 

 water. 



Ellisii, Reichb. f. {Grammatophyllum Ellisii, Lindl.). 

 Pseudobulbs 7-11 in. long, each bearing 5-6 Ivs.: Ivs. 

 1J2-2 ft. long: sepals yellow, elegantly marked with 

 dark transverse lines; petals and lip pale pink, the latter 

 with a strong mid-nerve. Summer. Madagascar. B.M.

G. liuttonii, Benth. & Hook. (Cymbidium Huttonii. Hook. f.). 

 Pseudobulbs of a single internode, 3-5 in. long, elongated, obovoid, 

 green: Ivs. iu pairs. G-8 in. long, 2-2^2 in- wide, dark green, coria- 

 ceous: raceme about 10-fid.. drooping; sepals obovate, recur\'ed,

 color; lip greenish, ^lith chocolate stripes. June. Java. B.M. 5676.

GRAMMANTHES (Greek, letter-flourr; the petals of 

 the full-colored varieties have a darker mark like a 

 letter V, whence also the name of the sj-nonymous 

 genus Vauanthes). Crassulaceec. One small very vari- 

 able half-hardy, succulent annual, with thick fleshy 

 leaves and yellow flowers, growing about 6 inches high 

 and is used for edgings, baskets and pots. 



Erect, forking: calyx bell-shaped, scmi-5-fld.; corolla- 

 tube as long as the calyx: limb 5-6-lobed: carpels 5-6, 

 many-o\T.ded, with awl-shaped styles: scales minute, 

 or evanescent: folhcles many-seeded. In sandy groimd 

 in the western part of the Cape region, S. Afr. 



dichotoma, DC. (G. geniidnoidcs, DC). Glabrous, 

 somewhat glaucous: branches forking: sts. rigid, 

 fihform: Ivs. opposite, distant, oblong, ovate or nearly 

 linear: fls. orange, yellow, or creamy white, and marked 

 as above described. F.S. 5:518. Var. vera, (Harv.), 

 has Ivs. ovate-oblong: hmb of corolla ovate-oblong, a 

 third longer than the stamens. Var. chloraeflora, (Harv.), 

 has Ivs. oblong or hnear: fls. a httle larger; hmb of 

 coroUa ovate-lanceolate, twice as long as the stamens. 

 B.M. 4607, 6401. There are other named forms. Some 

 of them are very depauperate in their native region, 

 some of them only 1-2 m. high. Wilhelm Miller. 



GRAMMATOCARPUS: Sci/phanthus. 



GRAMMATOPH'i'LLUM (Greek, gramma, a Hne or 

 streak, and phylloii, leaf; probably referring to the 

 parallel leaf-veins). Orchiddcese, tribe Vdndese. A 

 group of perhaps 8 or 9 epiphytic species, of which 

 about half are well-defined, inhabiting the islands from 

 Madagascar to the Philippines and New Guinea. The 

 genus includes some of the largest and showiest of 

 cultivated orchids. 



Roots numerous: sts. or pseudobulbs many-lvd.: Ivs. 

 long, ribbon-shaped, thick, evergreen: racemes long- 

 stalked, loosely many-fld., springing from near the base 

 of the pseudobulb; fls. large, not obviously spurred; 

 sepals and petals nearly equal, spreading; lij) compara- 

 tively small, with margin entirely free, 3-lobed, with 

 erect lateral lobes; column slender. .Vllied genera are 

 Grammangis and Cymbidium, from both of which 

 Grammatophyllum differs in having the pollen masses 

 each borne upon an appendage of the stalk, while in 

 the two related genera they are attached to a common 

 stalk without special appendages. 



The few species in cultivation are such infrequent 

 bloomers that the flowering of a fine example is some- 

 thing of an event. They are ))rt)pagated from pieces of 

 the pseudobulbs. The plants arc best grown in good-
