GALEGA 
Galega Tourn. ex Linn. Leguminosae (ill. 6). 3 sp. S. Eur., W. As. 
G. officinalis L. is sometimes cultivated as a fodder-plant (goat’s rue). 
Galeobdolon Adans. =Lamium Tourn. 
Galeopsis Linn. Labiatae (vi. 4). 7 sp. N. temp. 3 in Brit., in- 
cluding G. Tetrahit L., the hemp-nettle, noteworthy for the swollen 
upper ends of the internodes; these act as pulvini (p. 49). See 
Briquet’s monograph of G., Mem. cour. Acad. roy. Belg. LII. 1893. 
Galinsoga Ruiz et Pav. Compositae (v). 4 sp. Mexico to Argentina. 
G. parvifiora Cav. is now a common weed on the continent, and is 
established near Kew. 
Galipea Aubl. Rutaceae (v). 6 sp. S. Am. 
Galium Linn. Rubiaceae (11. 21). Over 200 sp. mostly temp., 10 in 
Brit, (bed-straw, &c.). Herbs with whorls of leaves and stipules (see 
order), and firs, in dichasial panicles. Fir. small with honey freely 
exposed (p. 89) on the epigynous disc ; in most sp. it is protandrous 
with ultimate self-pollination. Of the Brit, sp., G. verum L. and 
G. Aparine L. (goose-grass or cleavers) are the most frequent. The 
latter is a feeble hook-climber (p. 172), with small reflexed hooks on 
the stem. The schizocarp is also provided with hooks. 
Galtonia Dene. Liliaceae (11). 2 sp. S. Afr. 
Gamopetalae (Benth. -Hooker) = Sympetalae (p. 134). 
Garcinia Linn. Guttiferae (v). 150 sp. trop. Old World. Trees or 
shrubs with leathery leaves. Sta. free or united into bundles or into 
a common mass. Fruit a berry. Seed arillate. The resin of G. 
Morelia Desr. and other sp. , obtained by cutting notches in the stem, 
forms gamboge. The fruit of many sp. is edible, especially that of G. 
Mangostana L., the mangosteen; it is the aril of the seed of this 
which is esteemed as a delicacy. Some sp. yield useful timber. 
Gardenia Ellis. Rubiacae (1. 8). 60 sp. trop. Old World. They are 
largely cultivated for their showy strongly-scented flrs. Some sp. 
have apparently whorls of leaves, 3 in each. This is really a case of 
condensation of two whorls of 2 into one with extreme anisophylly 
(p. 47) of one whorl; the fourth leaf is reduced to a minute scale. 
The stipules of many sp. secrete a resinous fluid. 
GarideUa Tourn. ex Linn. =Nigella Linn. 
Garrya Dougl. ex Lindl. Cornaceae. 8 sp. Calif., Mexico, W. Ind. 
G. elliptica Dougl. is often found in shrubberies. The flrs. are in 
catkins ; 3 flrs. occur in the axil of each bract. 
Gasteria Duval. Liliaceae (in). 35 sp. S. Afr. Xerophytes with 
succulent leaves closely packed together (p. 167), but living in the
