BB. Rays spotted at base: heads 3 in. or more across. 



pinnata, Less. Rootstock perennial, fibrous: Ivs. 

 commonly pinnate (some simple); lobes oblong or 

 linear in several pairs; white on both surfaces and stiff- 

 hairy: peduncle not much longer than Ivs.; involucral 

 scales acuminate, particularly the inner ones. Harvey 

 names 6 botanical varieties. 



AA. Color of heads orange: rays spotted at base: heads 



3 in. or more across. 

 B. Lvs. mostly entire and spatulate. 

 c. Basal markings containing brown. 

 rtgens, R. Br. Sts. short and densely leafy or dif- 

 fuse, laxly leafy, with ascending branches: Ivs. some- 

 times sparingly pinnatifid, i. e., with only 1 or 2 side 

 lobes, white beneath except on the midrib: heads large 

 and showy, 1 Yi in. wide, the rays orange, disk purplish 

 black. B.M. 90 (as Gorteria rigens) shows a head of scarlet 

 rays, with basal markings of brown, black and white. 



cc. Basal markings without brown. 

 splendens, Hort. Fig. 1623. Hybrid, said to resem- 

 ble 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. H.F. II. 4:240. 



BB. Lvs. mostly pinnate. 



Pavonia, R. Br. PEACOCK GAZANIA. Involucral 

 scales short, the inner broad, acute or subacute. B.R. 

 35 shows markings of brown, white, yellow and blue, 

 which are marvelous in design and precision of 

 execution. 



AAA. Color of heads white above. 



pygmsea, Sond. Crown woody and much divided: 

 Ivs. spatulate, entire: rays white, striped purple beneath. 

 Gn. 47:288. 1.11.43:53. B.M. 7455. G. 30:101. 

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

 with a blackish spot at the base, reverse striped dull 

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

 reverse striped bluish. Var. lutea, Hprt. Fl.-heads 

 very large, chrome-yellow. This species is very variable 

 in its involucral scales, which may be short or long, 

 sometimes cup-shaped at the base, and again almost 

 free. This upsets one of the most important features 

 of Harvey's key. 



A hybrid between G. nivea, Less., and G. longiscapa, DC., known 

 as G. hybrida, has been described as a very prof use bloomer, flowering 

 continuously from June to late autumn. R.H. 1900:209. Gt. 

 47:134. G. longiscapa, DC. (G. stenophylla, Hort.), is a white- 

 woolly perennial with a glabrous peduncle which is shorter than the 

 Ivs. : involucre glabrous. G. nivea, DC. Very dwarf, almost woody: 

 jvs. crowded, hoary-tomentose on both sides: peduncle not exceed- 

 ing the Ivs.: involucre tomentose. Last two probably not cult, in 



Amer - WILHELM MILLER. 



N. TAYLOR-f 



GEISSORHIZA (Greek words alluding to the coats of 

 the bulb, which cover it somewhat like overlapping 

 tiles). Iridacese. Ixia-like half-hardy Cape bulbs, 

 which are dormant from August to November and are 

 usually flowered under glass in spring and early 

 summer. 



Cormous: Ivs. few, distichous: fls. in different colors, 

 in open, simple or forked spikes; perianth nearly regu- 

 lar, rotate, with a cylindrical tube; stamens 6, inserted 

 in the throat; ovary 3-celled, becoming a small oblong 

 caps. Species about 30, 1 in Madagascar and the 

 others in S. Afr. 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 are advertised. 



rochensis, Ker. Corm J/in. diam., globular: Ivs. 3, 

 one of them on the st., glabrous, basal ones narrow, 

 few-ribbed: st. 3-6 in., simple or forked, with 1 fl. at 

 the top; st.-sheath loose and swelling: fls. violet-purple, 

 1-2 in. across; perianth-tube shorter than the spathe; 

 segms. with a blotch at the base. B.M. 598, 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. 



hirta, Ker. Lvs. hairy: fls. 2-6 in a loose spike, bright 

 red, the tube very short, segms. not blotched: corm 

 2^in. diam., globular. Offered in S. Calif. L. H. B. 



GEITONOPLESIUM (Greek-made name, near 

 neighbor, in allusion to its kinship to another genus). 

 Liliacese. Woody stemmed twiners of Austral, and 

 Pacific islands of probably 2 species; one is offered in 

 S. Calif. Fls. small, in loose terminal clusters: Ivs. 

 alternate, linear to ovate, very short-stalked, lightly 

 nerved; perianth with 6 oblong distinct segms., the 3 

 outer ones more or less hood-shaped at times, the inner 

 ones flat and obtuse; stamens 6, included: fr. a nearly 

 globular berry with thin pulp and becoming dry; seeds 

 irregular, black. G. cymSsum, Cunn. Tall-climbing, 

 with wiry sts. : fls. purplish green, the perianth ^iin. 

 or less long, the pedicels very short and jointed under 

 the fl. : berry dark blue, J^in. or less diam. ; seeds few. 

 Queensland to Victoria. B.M. 3131. L. H. B. 



GELSEMIUM (from the word Gelsemino, the Italian 

 name of the true jessamine). Loganidcese. Climbing 

 shrubs, with evergreen foliage and yellow flowers. 



Glabrous, twining, shrubby plants, with opposite, 

 rarely whorled Ivs., and showy, hypogynous, per- 

 fect, regular, yellow and very fragrant fls., in axil- 

 lary and terminal cymes, the pedicels scaly-bracted : 

 calyx imbricated, deeply 5-parted; corolla funnel- 

 form, 5-lobed, imbricated in the bud; stamens 5, 

 epipetalous; ovary solitary, superior, 2-celled; ovules 

 numerous, on narrow placentae; style slender, 4-cleft: 

 fr. an elliptic, septicidal caps., flattened contrary to 

 the partition; valves boat-shaped, 2-cleft at the apex; 

 seeds flattened and winged. There are 2 species in 

 the genus, one American the other Chinese. The 

 American or Carolina yellow jessamine is a well-known 

 woody twiner of the S., bearing evergreen foliage and 

 a profusion of bright yellow, very fragrant fls. The 

 cymes of the Chinese species are terminal and trichot- 

 omous. Our species is very desirable for covering 

 banks and fences in any soil. It is also grown occasion- 

 ally in conservatories. The rhizomes and roots are used 

 medicinally as a nervine, antispasmodic and sedative. 

 The true jessamine is Jasminum officinale (Oleaceie) of 

 Eu. 



sempervirens, Ait. f. CAROLINA YELLOW JESSA- 

 MINE. St. high-climbing: Ivs. ovate, or lanceolate, 

 shining, entire, short-petioled, 1-3 in. long: cymes 

 terminal, 1-6-fld.; the fls. dimorphous; corolla 1-1 Yt 

 in. long. Low woods and thickets, Va. to Fla., Texas 

 and Guatemala; early flowering. B.M. 7851. G.W.

GENETYLLIS: Darwinian 



GENIPA (Brazilian name). Rubiacese. This includes 

 a West Indian shrub allied to the Cape jasmine and 

 barely known to American horticulture. Genipa and 

 Gardenia are difficult to separate. 



Small trees or shrubs: 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

 so large in cult.: Ivs. 4 in. or less long, black when 

 dried, obovate, glabrous: corymbs short-peduncled ;
