 markings of brown, black and. white.

 spl^ndens, Hort. Fig. 895. Hybrid, said to resemble 

 O. uftifhrra in habit but dwarfer and ni<jre compact, (')f 

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

 in coloring of Us.

 Pavdnia, R. Br. Peaoock 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 snhjicute.

 with a blackisli spot at the l)ase. reverse strii)ed dull 

 purple. Var. sup6rba, 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'. ^,l^

GEIGER TREE, ConJIa ^ehesteua 



GEISSORHiZA (Greek words alluding to the coats of 

 the bulb, whic4i cover it somewhat like overlapping 

 tiles). Iridcteeae. Al)Out 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 art- all green and membra- 

 nous at the tip, w^hile in Ixia the outer spathe-valve is 

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

 wide range in habit and in color of fis., I'ut 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.

Rochensia, Ker. Lvs. i^htbrous, basal ones narrow, 

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

 across; ])erianth tube shorter than the spathe; seg- 

 ments with a nectary at the base. B.M. 598 (not 072, as 

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

 trifle over 8 in. high and the l^s. imrple. with a dark red 

 eye, the hitter surrounded by a pah- blue cinde. 



GELSEMIUM (from an Italian name of the true Jessu- 

 niine, whitdi belongs to a different order). LoganitU'ei''. 

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

 < 'aroliiia Yellow Jessamine, our native woody twiner of 

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

 green foliage and a profusion of axillary clusters of 

 briglit 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-celIed : pod oval, flattened con- 

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

 winge<l. 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, rich 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.

 lanceolate or ovate, acute or subcordate at the 

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

 swamps and rivers. Va. to Fla. A double-fid. 

 form is advertised. -^ ]\[ 



GENlPA(Brazilian name). Bahidcecp. This 

 includes a West Indian shrub allied to the 

 Cape Jasmine and handy known to Ameri- 

 can horticulture. Genipa and Gardenia are 

 hard to separate. Small trees; lvs. with short 

 or no stalks, opyiosite, large, leathery, obovate 

 or lanceolate, shining : cymes axillary, few- 

 dd.: 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 l>ilad: ovary 1-celled: 

 placentas 2, almost touching each other in the 

 axis: l)erries edible. 



clusiifblia, Griseb. Shrub on maritime rocks 

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

 obovate, glabrous : corymbs short-peduncled: calyx limb 

 5-cut : corolla glabrous: berry ovoid. 



GEN t ST A (ancient Latin name). Legutninosce. Orna- 

 mental low shrubs with small ileciduous or half ever- 

 green lvs., showy j'ellow ds., generally in terminal 

 racemes or clusters, appearing profusely in spring or 

 summer, and followed by small, insignificant pods. None 

 of the species is ciuite hardy North, but O. tinctoria, 

 Aiiijlica, Ger>tianica 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. Tliey are well 

 adapted tor covering dry, sanely banks and rocky slopes, 

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

 drained soil, and like a sunny pjosition. 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: lvs. 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.
