Gastonia continued. 



I. at the tops of the branches, impari -pinnate ; leaflets six to eight, 

 coriaceous, ovate, obtuse, quite entire. Mauritius. A tall, smooth 

 tree, covered with spongy bark. This plant is now referred to 

 the genus Polyscias. 



GASTRODIA (from gaster, a belly; referring to the 

 swelling of the column in front). ORD. Orchidece. A 

 genus of about seven species of tall, slender, leafless, 

 whitish or brown terrestrial orchids, found in Australia, 

 New Zealand, and the Indian Islands. For culture, see 

 Fogonia. 



G. Cunningham!! (Cunningham's), fl. dirty green, spotted with 

 white ; bracts short, scarious ; claw of lip winged ; blade linear- 

 oblong, membranous, waved, with two thick ridges down the 

 middle ; column very short. Stem 1ft. to 2ft. high ; root some- 

 times 18in. long, very stout. SYN. G. sesamoutes. 

 G. sesamoides (Sesamum-like). A synonym of G. Cunninghamii. 

 GASTROLOBIUM (from gaster, the belly, and 

 lobos, a pod; in reference to the pods being inflated). 

 ORD. Leguminosce. A genus, containing thirty-two species 

 of greenhouse evergreens, limited to Western Australia. 

 It is closely allied, on the one hand, to the strophiolate 

 species of Oxylobium, only differing from them in the 

 number of ovules, constantly two ; and, on the other, to 

 Pultenaea, from which it is distinguished by the habit, 

 the coriaceous leaves, the bracteoles either deciduous 

 or inconspicuous, and the more coriaceous turgid pod. 

 Flowers yellow, or the keel and base of the standard 

 purple-red, in terminal or axillary racemes, either loose 

 or contracted into corymbs or whorl-like clusters ; bracts 

 and bre,cteoles usually very deciduous. Leaves on very 

 short petioles, more or less distinctly verticillate or oppo- 

 site, simple and entire, usually rigid ; stipules setaceous, 

 rarely wanting. For culture, see Pultenaea. 



G. bilobum (two-lobed).* fl. numerous, in very short, almost 

 umbel-like terminal racemes. March to May. I. mostly verticil- 

 late, in threes or fours, from obovate to narrow-oblong, thinly 

 coriaceous, glabrous and veined above, pale and often minutely 

 silky pubescent underneath. 1839. A tall shrub. (B. M. 2212 ; 

 B. R. 411 ; L. B. C. 70.) 



G. calyclnum (large-calyxed).* fl., racemes terminal or in the 

 upper axils ; bracts larger and more membranous than in any 

 other species. 1. opposite or in threes, oblong-elliptical, or more 

 frequently from ovate-lanceolate to lanceolate, with a pungent 

 point, coriaceous, rigid, reticulate, and often glaucous. An erect 

 shrub. 



G. emarginatum (emarginate). A synonym of G. velutinum. 



G. trilobum (three-lobed). fl. few, in loose axillary racemes, not 

 usually exceeding the leaves. I. rhomboidal or three-lobed, some- 

 times lanceolate, sometimes very broad and short, very coriaceous, 

 often glaucous, the fine reticulations scarcely prominent. A much- 

 branched, quite glabrous species. 



G. velutinum (velvety), fl. orange-red, in terminal, rather dense 

 racemes ; bracts ovate, very deciduous. April. L verticillate in 

 threes or fours, from obovate or obcordate to linear-cuneate, very 

 obtuse or truncate, emarginate; margins recurved, coriaceous, 

 reticulate, glabrous above, usually pubescent underneath. 

 Branches rather stout, angular, minutely silky pubescent. An 

 elegant species. SYN. 0. emarginatum. 



GASTRONEMA. A synonym of Cyrtanthus 



(which see). 



GATHERING. See Fruit Gathering. 



GAUB, or GAB. Indian names for the astringent 

 fruits of Diospyros Embryopteris. 



GAUDICHAUDIA (named in honour of Charles 

 Gaudichaud, who accompanied Freycinet as naturalist in 

 his voyage round the world, 1817-20). ORD. Malpi- 

 ghiacece. A genus comprising twelve species of graceful, 

 mostly twining stove shrubs, inhabitants of Mexico, 

 New Grenada, and Venezuela. The species of this 

 genus, like those of some other genera of the same 

 family, are remarkable for constantly producing two 

 kinds of flowers. Flowers yellow ; petals sometimes 

 perigynous, roundish, spreading. In the more imper- 

 fect flowers, the petals are either rudimentary or alto- 

 gether absent. Leaves opposite, entire. The species 

 given below is the one in general cultivation. For 

 culture, see Galphimia. 



Gaudichaudia continued. 



G. cynancholdes (Cynanchum-like). fl. yellow, in axillary or 

 terminal crowded racemes. I. stalked, h. 10ft. Mexico, 1824. 



GATJLTHBRIA (named in honour of Gaulthier, a 

 physician and botanist of Canada). Aromatic Winter-

green. SYN. Gualtheria. ORD. Ericaceae. A genus 

 comprising about ninety species of very ornamental hardy 

 or greenhouse small trees or shrubs, inhabitants of the
