GAZANIA 



GENISTA 



631 



lobes B.M. 90 shows a head of scarlet rays, with basal 

 markings of brown, black and white. 



cc. Basal markings without brown. 



splendens. Hort. Fig. 895. Hybrid, said to resemble 

 G. uniflora in habit but dwarfer and more compact. Of 

 the kinds in common cult, it is nearest to G. Pavonia 

 in coloring of fls. 



BB. Lvs. mostly pinnate. 



Pavdnia, R. Br. PEACOCK GAZANIA. B.R. 1:35 shows 

 markings of brown, white, yellow and blue, which are 

 marvelous in design and precision of execution. Invo- 

 lucral scales short, the inner broad, acute or subacute. 



895. Gazania splendens (X %). 



AAA. Color of heads white above. 



pygmsea, Sond. Lvs. spatulate, entire. Rays white, 

 striped purple beneath. Gn. 47:1011. I. H. 43:53. B.M. 

 7455. Var. maculata, N.E. Br. Rays pale creamy white, 

 with a blackish spot at the base, reverse striped dull 

 purple. Var. supgrba, N. E. Br. Rays white, unspotted, 

 reverse striped bluish. This species is very unreason- 

 able about its involucral scales, which may be short or 

 long, sometimes cup-shaped at the base, and again al- 

 most free. This upsets one of the most important fea- 

 tures of Harvey's key. W. M. 



GEAN. Prunus Aviuvn. 



GEIGER TREE. Cordia Sebestena 



GEISSORHlZA (Greek words alluding to the coats of 

 the bulb, which cover it somewhat like overlapping 

 tiles). Iridaceae. About 30 species of Ixia-like, half- 

 hardy Cape bulbs, which are dormant from Aug. to Nov., 

 and are usually flowered under glass in spring and early 

 summer. The spathe-valves are all green and membra- 

 nous at the tip, while in Ixia the outer spathe-valve is 

 short, brown and notched at the tip. The genus has a 

 wide range in habit and in color of fls., but these plants 

 are presumably inferior to Ixias for general culture. 

 The following species is advertised in some of the 

 Dutch bulb catalogues that are printed in English.

Rochensis, Ker. Lvs. glabrous, basal ones narrow, 

 few-ribbed: stem-sheath loose and swelling: fls. 1-2 in. 

 across ; perianth tube shorter than the spathe; seg- 

 ments with a nectary at the base. B.M. 598 (not 672, as 

 stated in Index Kewensis), where the whole plant is a 

 trifle over 3 in. high and the fls. purple, with a dark red 

 eye, the latter surrounded by a pale blue circle. 



GELSEMIUM (from an Italian name of the true Jessa- 

 mine, which belongs to a different order). Loganiacece. 

 A genus of only 2 species, the typical one being the 

 Carolina Yellow Jessamine, our native woody twiner of 

 the South, which climbs on trees and bears shining ever- 

 green foliage and a profusion of axillary clusters of 

 bright yellow, very fragrant, handsome fls., 1 in. or 

 more long, in early spring. Lvs. opposite, membranous, 

 the leaf -stalks joined by a transverse stipular line: 

 calyx 5-parted; corolla open funnel-shaped, the 5 lobes 

 broad and imbricated in the bud; stamens 5; anthers 

 arrow-shaped; style slender; stigmas 2, each 2-parted, 

 lobes linear: ovary 2-celled : pod oval, flattened con- 

 trary to the partition, 2-valved, many-seeded : seeds 

 winged. The cymes of the Chinese species are terminal 

 and trichotomous, of ours axillary, 1-3-fld. Reasoner 

 considers ours one of the best of southern vines, and says: 

 "Not cult, to the extent it deserves. Will grow on any 

 land, rjch or poor, wet or dry. Quick-growing, and for 

 several weeks in spring literally covered with its lovely 

 fragrant yellow flowers." It is somewhat grown for 

 winter bloom in northern conservatories. Preparations 

 of the rhizome and roots are common in drug stores. 

 Properties nervine, antispasmodic, sedative. 



semp6rvirens, Ait. St. purplish: Ivs. small, 

 lanceolate or ovate, acute or subcordate at the 

 base, short-petioled. Mar., Apr. Margins of 

 swamps and rivers. Va. to Fla. Adouble-fld. 

 form is advertised. ^ ]yj. 



GENlPA( Brazilian name). RuU&cece. This 

 includes a West Indian shrub allied to the 

 Cape Jasmine and barely known to Ameri- 

 can horticulture. Genipa and Gardenia are 

 hard to separate. Small trees: Ivs. with short 

 or no stalks, opposite, large, leathery, obovate 

 or lanceolate, shining : cymes axillary, few- 

 fld. : fls. white to yellowish ; calyx limb bell- 

 shaped,truncated,or 5-toothed; corolla salver- 

 shaped, limb twisted to the left, 5-parted ; 

 stigma club-shaped or bifid: ovary 1-celled: 

 placentas 2, almost touching each other in the 

 axis: berries edible. 



clusiifdlia, Griseb. Shrub on maritime rocks 

 of Cuba, etc. : Ivs. 4 in. or less long, black when dried, 

 obovate, glabrous : corymbs short-peduncled: calyx limb 

 5-cut : corolla glabrous: berry ovoid. 



GENlST A (ancient Latin name). Legumindsce. Orna- 

 mental low shrubs with small deciduous or half ever- 

 green Ivs., showy yellow fls., generally in terminal 

 racemes or clusters, appearing profusely in spring or 

 summer, and followed by small, insignificant pods. None 

 of the species is quite hardy North, but G. tinctoria, 

 Anglica, Germanica and some other European species 

 will do well in a sheltered position or if somewhat pro- 

 tected during the winter, while the others are more 

 suited for cult, in southern regions. They are well 

 adapted for covering dry, sandy banks and rocky slopes, 

 and for borders and rockeries. They grow in any well- 

 drained soil, and like a sunny position. Prop, by seeds, 

 sown in spring, also by layers and by greenwood cut- 

 tings under glass. About 80 species in Europe, Canar., 

 N. Afr., W. Asia. Allied to Cytisus, but without callose 

 appendage at the base of the seeds: branches usually 

 striped, sometimes spiny: Ivs. entire, alternate, rarely 

 opposite, simple, sometimes 3-foliolate: fls. yellow, rarely 

 white, style hardly curved; calyx 2-lipped, with the up- 

 per lip deeply 2-parted. The Genista of florists is 

 Cytisus.
