GALEDUPA: Pongamia. 



GALEGA (Greek, gala, milk: supposed to 

 increase the flow of milk). Leguminosse. 

 Bushy perennials not very commonly cultivated in 

 America. 



Of 120 names of species in this genus, only 6 are now 

 retained, most of the others being referred to Tephrosia. 

 The plants mentioned below are hardy herbaceous 

 perennials of the easiest cult., about 3 ft. high, with odd- 

 pinnate Ivs. and pea-shaped fls. of purplish blue or 

 white. They do not require frequent division, make 

 bushy plants, and bear in July and Aug. many dense, 

 axillary and terminal racemes of fls., which are useful 

 for cutting. Seeds of goat's rue are still offered abroad 

 among miscellaneous agricultural seeds, but the plants 

 are little known in this country. They are native in 

 S. Eu. and W. Asia. 



A. Lfts. lanceolate: stipules broadly lanceolate. 

 officinalis, Linn. GOAT'S RUE. Fig. 1618. Height 

 2-3 ft.: Ifts. mucronate: fls. purplish blue. Eu., W. 

 Asia. G.M. 49:57. Var. alba or albiflora is commoner 

 in cult. Gn. 50, p. 269. G.L. 22:294. J.H. III. 

 48:557. Var. Hartlandii, Hort., has large spikes 

 of lilac fls. and the young foliage variegated. A.F. 

 22:695. A rose-colored variety is sold as var. carnea, 

 Hort., which is also known in a double-fld. form; a 

 dwarf, compact, lilac-fld. variety sold under the name 

 var. compacta, is also known.

 blance). Labiatse. HEMP NETTLE. Several weedy 

 European plants, some of them naturalized in this 

 country, rarely cult, in gardens. Annuals, of spreading

habit, opposite Ivs. that are dentate or entire, and red, 

 yellowish or variegated fls. in whorls toward the top of 

 the st. : calyx with 5 nearly equal teeth; corolla widened 

 in the throat, bearing an entire arched upper lip and a 

 palate with 2 teeth. G. Ladanum, Linn., is canescent, 

 with very narrow, nearly or quite entire Ivs. : fls. rose- 

 red or red, sometimes spotted yellow: 8-12 in.: there 

 are forms with broader Ivs. and also narrow Ivs., and 

 otherwise variable. G. versico- 

 lor, Curt., has hispid sts., ovate 

 coarsely toothed Ivs., and large 

 yellowish fls. with purple spot 

 on lower lip: by some con- 

 sidered to be a form of the 

 next with larger yellow-and- 

 purple fls. and an arched rather 

 than flat upper lip. G. Tetfahit, 

 Linn., is bristly-hairy with st. 

 swollen beneath the joints, 

 erect: Ivs. ovate, toothed: fls. 

 purplish or white or parti- 

 colored. L. H. B. 



GALEORCHIS (in reference 

 to the hood-like organ formed 

 of the united sepals). Orchi- 

 ddceae. Orchids with fleshy roots : 

 st. scape-like, with 2 basal Ivs. : 

 fls. in a short, loose spike, ex- 

 ceeded by the large 

 bracts; sepals united, 

 forming a hood; petals 

 connivent; lip entire, 

 spurred; column short; 

 pollinia granulose, 1 

 mas in each sac, tailed. 

 ^spect&bilis, Rydb. 

 (Orchis spectdbilis, 

 Linn.). SHOWY ORCHIS. St. up to 1 ft. tall, 5-angled: 

 spike 3-6-fld.; fls. violet-purple, variegated with lighter 

 purple and white. N.E.N.Amer. GEORGE V. NASH. 



GALIUM (Galion was the name of a plant men- 

 tioned by Dioscorides as used in curdling milk. G. 

 verum is locally used abroad for this purpose). Rubia- 

 cese. BEDSTRAW or LADIES' BEDSTRAW, so-called because 

 of the legend that one of these plants was in the hay 

 on which the mother of Christ rested. Mostly weak or 

 slender herbaceous plants with square, often barbed 

 stems, and whorled leaves. 



Flowers very small, perfect, epigynous; calyx almost 

 or quite obsolete; corolla gamopetalous, rotate, deeply 

 4-parted; divisions in our species acute or acuminate; 

 stamens 4; ovary inferior, 2-celled, forming a 2-lobed, 

 2-seeded, dry, indehiscent fr.; the lobes nearly globular. 

 About 220 species in various parts of the world. 

 Noted for the recurved-scabrous sts. of many species, 

 mathematical habit due to the whorled Ivs., and the 

 fine fluffy fls. The profuse-flowering species noted 

 below are often used in rockeries and flower-beds for 

 the regular but soft and filmy effect, which is similar 

 to that of gypsophila. As cut-fls., they are used to 

 lighten the effect of heavier fls. 



A. F Is. yellow. 



verum, Linn. YELLOW BEDSTRAW. Perennial from 

 a somewhat woody base: sts. erect, smooth, tufted, 

 1-3 ft. high: Ivs. in 8's or 6's, linear, %-l in. long; 

 apex bristle-tipped: panicle ample, its lower branches 

 exceeding the Ivs. Eu., now also a weed in fields in 

 the E. U. S. A very good plant for rockeries and banks. 



AA. Fls. white. 

 B. Lvs. in 4's, lanceolate, several-nerved. 



boreale, Linn. NORTHERN BEDSTRAW. Perennial, 

 stoloniferous, forming patches: sts. smooth, 1-3 ft.
