PELARGONIUM 



PELARGONIUM 



2531 



and sharp-toothed, the stipules ovate and mucronate: 

 fls. about 3 on each peduncle, the stalk-like calyx-tube 

 3-4 times as long as the lanceolate segms., the obovate 

 white petals (upper 2 with red lines) 3 times as long 

 as calyx-segms. A handsome and distinct species, 

 probably not now in 

 cult, in its pure form. 

 Intro, to England in 

 1794. 



9. multibracteatum, 

 H o c h s t . Somewhat 

 shrubby below, 1-2 ft., 

 thinly hairy but be- 

 coming glabrous: Ivs. 

 palmately about 7-cut 

 or -lobed, the segms. 

 broadly oblong or 

 ovate, serrate or cre- 

 nate, more or less hairy , 

 2-5 in. across; stipules 

 about Hin. long, ovate 

 to elliptic.: peduncles 

 long, 6 in. to 1 ft., 

 bearing 6-10-fld. um- 

 bels; fls. whitish or 

 white, on pedicels 

 about 1^ in. long; 

 petals obovate -spatu- 

 late, entire, twice 

 longer than the narrow 

 sepals. Trop. Afr. G. 

 M. 54: 628. 



10. transvaalense, 

 Knuth (P.Thorncroftii, 

 Hort.). Erect, 16 in. 

 to 2 ft. in bloom, the st. 

 terete and soft-hairy, 

 sparingly branched : 

 Ivs. few, cordate-angu- 

 lar in outline, 5-7- 

 lobed, the lobes tri- 

 angular or rhomboid, 

 serrate-dentate, the 

 petiole as long as blade 

 or longer; stipules 

 broadly ovate, acute: 

 umbels many, corym- 

 bose at apex of st.; fls. 



nearly Sessile, rose- 2 84S. Domesticum pelargonium, 



colored or carmine- one of the Show or Lady Washing- 

 rose, or pale pink, 1% ton pelargoniums (X^). No. 21. 

 in. across vertically, 



the 2 larger petals strongly narrowed at base and 

 emarginate at top, the 3 smaller ones paler and retuse 

 or emarginate. Transvaal, 3,000 ft. altitude. G.C. III. 

 55:103. 



AAAA. Plant with thick succulent branches, and strong 

 fishy odor, shrubby in the wild and in warm coun- 

 tries: Ivs. obovate, orbicular or reniform, shal- 

 lowly if at all lobed: infl. umbel-like; good stamens 

 7, the 2 upper ones short; petals typically all of one 

 color. (Ciconium.) FISH or BEDDING GERANIUMS. 



11. zonale, Willd. (Geranium zonale, Linn.). ZONAL 

 or HORSESHOE GERANIUM. Shrubby, becoming woody 

 at the base even in pots, the young branches succulent 

 and somewhat hispid: Ivs. round-cordate, glabrous or 

 pubescent, long-stalked, usually with a zone or horse- 

 shoe mark of deeper color on the upper surface, the 

 margin crenate-dentate, with several very shallow 

 rounded lobes; stipules broad, cordate-oblong: pedun- 

 cles long, the many fls. nearly sessile; calyx-tube gla- 

 brous or nearly so, 4-5 times longer than the lanceolate 

 segms.; petals separated, narrow-wedge shape or 

 spatulate. S. Afr., "among shrubs and on hillsides. 

 . . . The fls. vary from scarlet and crimson through 



all shades of red to pure white." Harvey. Probably 

 originally red. P. zonale was intro. into England in 

 1710. Linnaeus described it in 1753 as Geranium zonale, 

 founding the species on previous descriptions, not on 

 specimens. It is probable that the species had been 

 considerably modified by domestication when Linnaeus 

 wrote. There seems to be no accepted early portrait of 

 the original form of the plant. 



12. inquinans, Ait. (Geranium inquinans, Linn.). 

 FISH GERANIUM. Fig. 2836. Plant more velvety than 

 P. zonale, sometimes more or less viscid, the Ivs. not 

 zoned: Ivs. long-petioled, orbicular-reniform, crenate, 

 only obscurely many-lobed, velvety and somewhat 

 viscid: calyx-tube densely glandular and viscid, 3-4 

 tunes longer than the lanceolate segms. ; petals broadly 

 obovate, scarlet, but now varying to lighter colors. 

 "Among shrubs and on hillsides." This is the Geranium 

 inquinans of Linnaeus, who founded the species on pre- 

 vious descriptions. One of the descriptions 

 '-, (Dillenius, in "Hortus Elthamensis," 1732) 



was accompanied by a picture, and this pic- 

 ture, reduced, is reproduced in Fig. 2836. It 

 will be seen that even in that early day the 

 species had varied into a form with short- 

 notched petals and short pedicels. Intro, 

 into England in 1714. Said by Harvey 

 (1859-60) to be the parent of most of the 

 "scarlet geraniums" of English gardens. 



13. hortSrum class. COMMON FISH or 

 BEDDING GERANIUM. Fig. 2840. The com- 

 mon geranium in great numbers of forms, 

 derived from the variation and probably 

 J the blending of P. zonale and P. inquinans 

 (and possibly others) in more than a cen- 

 tury of careful selection. The original species 

 are not now in cult. Practically all garden geraniums 

 have the zonal marks on the Ivs., or bands, or a cen- 

 tral blotch of variegation. Some of them have inter- 

 mingled colors of green, white, and red on the same If. 

 Some are "silver-banded" and some "gold-banded." 

 (See Fig. 2840.) 



AAAAA. Plant with a short and thick more or less fleshy 

 st. or caudex, from which arise slender branches, 

 the Ivs. long-stalked and reniform or cordate and 

 obscurely lobed: stamens 6 or 7. (Cortusina.} 



B. With spine-like stipules. 



14. echinatum, Curt. Fleshy caudex armed with 

 persistent spine-like stipules: Ivs. long-petioled, white- 

 tomentose, cordate-ovate and obtuse, about 3-7-shal- 

 low-lobed, the lobes rounded and crenulate: peduncle 

 long and branched; fls. white, with a spot near the center 

 (varying to all purple), the petals notched ; calyx downy, 

 the tube several tunes longer than the lobes. B.M. 

 309. G.C. III. 46:245. J.H. III. 49:71. G.W. 15, p. 

 203. Now and then advertised. The fls. are said to 

 change color during the day; and the color may be 

 shades of purple. It is offered in S. Calif. 



BB. Without spines. 



15. odoratissimum, Ait. (Geranium odoratissimum t 

 Linn.). NUTMEG GERANIUM. Fig. 2841. Plant lax, 

 the sts. ascending or more or less tortuose: st. or caudex 

 very short, throwing up many slender and weak soft- 

 pubescent branches: Ivs. very long-stalked, soft, round- 

 cordate and very obtuse, the blade 1 in. or somewhat 

 more in length and broader, obscurely 3- or more-lobed. 

 the margins dentate-crenate; petioles 3-4 in. long and 

 shorter above; stipules triquetrous or broadly ovate, 

 usually connate : peduncles long and borne opposite the 

 Ivs., 5-10-fld.; fls. pedicelled, white or whitish; calyx 

 more or less pubescent, the spur Mj n - or l ess l n S the 

 sepals or lobes lanceolate, acute, with membranaceous 

 margins; petals twice or less longer than calyx-lobes, 

 about ^in. long, linear-spatulate, rounded at apex.
