PELARGONIUM 



PELARGONIUM 



2533 



P. domesticum is not the first name that has been applied 

 in this group, but the writer is not aware that any col- 

 lective or group name has been given. Sweet, in particu- 

 lar, has given Latin names to various forms. These old 

 names, however, apply to particular historical forms, 

 and it would be violence to 

 enlarge their application to 

 cover the entire group, and 

 it would be difficult to 

 choose any one of them 

 as more applicable, under 

 botanical rules, than others. 

 It is probably also inaccu- 

 rate to call this garden 

 form either P. cucuttatum or 

 P. angulosum. 



BB. Lvs. cordaie-ldbed, soft 



and velvety. 



22. tomentdsum, Jacq. 

 Plant rather thick- and soft- 

 stemmed, the branches 

 becoming several feet long, 

 white-hairy all over: Ivs. 

 very long - stalked, very 

 broadly cordate -ovate or 

 hastate - cordate at base, 

 3-5-7-lobed and small- 

 toothed, soft and velvety 

 on both surfaces; stipules ovate-acuminate, withering: 

 fls. small, white, with red near the center, in a lax 

 panicle, the pedicels many times longer than calyx-tube; 

 3 lower petals longer than sepals. B.M. 518. Scent 

 like peppermint, and for that reason it is somewhat 

 grown. The sts. are long and straggly. 



2848. Pelargonium Radula. 



BBB. Lvs. sharply 3-7-lobed and sharply toothed or 

 serrate. 



23. capitatum, Ait. (P. Drummondii, Turcz. Gera- 

 nium capitatum, Linn.). Sts. weak and trailing, but 

 suffruticose at base, with long white hairs: Ivs. long- 

 stalked, cordate, 3-5-lobed and the lobe rounded and 

 toothed; stipules broad-cordate, pointed: peduncles 

 longer than the Ivs., densely many-fld., the fls. sessile, 

 rose-purple, with calyx-tube much shorter than the 

 hairy mucronate calyx-lobes. B.M. 7346. 



Plant rose-scented, but not in general 

 cult, in its pure form; fls. in dense many- 

 fld. heads. 



24. vitifdlium, Ait. (Geranium viti- 

 folium , Linn.) . Erect, more or less woody, 

 densely hairy and villous: Ivs. long- 

 petioled, cordate at base, 3-lobed, the 

 lobes shallow and very obtuse and 

 rounded, dentate; stipules broad-cordate: 

 peduncle longer than If., simple and 

 densely many-fld. ; fls. sessile, small, pur- 

 ple; calyx-tube not half so long as the 

 hairy aristate segms. ; petals twice longer 

 than sepals, 2 of them larger and purple 



at base and the other 3 smaller and unicolored. 

 Differs from P. capitatum in erect habit and Ivs. less 

 deeply cut. 



BBBB. Lvs. deeply several to many-lobed, with narrow 

 divisions, rather rough or stiff, strong-scented. ROSE 

 GERANIUMS. 



25. quercifolium, Ait. (Geranium quercifdlium, 

 Linn. f.). OAK-LEAVED GERANIUM. SCARLET-FLOWER- 

 ING ROSE GERANIUM. Fig. 2846. Shrubby and branchy, 

 somewhat hairy and glandular: Ivs. with stalks 2-4 in. 

 long, cordate-ovate in outline, with 2-3 pairs of oblong 

 side lobes (Ivs. pinnatifid), which extend nearly to the 

 midrib and are again toothed and notched; stipules 

 small, 2 pairs at each node (or bifid) : fls. few to several, 

 rather small, red or purplish, in umbels and with short 



pedicels, the bracts laciniate; sepals elliptical and 

 mucronate, half as long as the petals. A rather com- 

 mon greenhouse plant, the Ivs. often with a dark spot, 

 and not agreeably scented. 



26. graveolens, L'Her. (Geranium 0rai>eokns,Thunb.) . 

 Fig. 2847. Much like the last, but Ivs. longer-petioled 

 and palmately 5-7-lobed or parted, the broad lobes 

 flat and pinnatifid into many mostly obtuse lobes; 

 stipules cordate-acute: fls. many, on mostly long pedun- 

 cles, pink or light purple, small, the calyx hairy and 

 nearly sessile, the calyx-lobes half as long as the petals. 

 This is one of the commonest forms of rose geranium, 

 a leafy plant with a rather heavy balsamic odor. A 

 If. is well depicted in Fig. 2847. There are many 

 derivatives from it. 



27. hispidum, Willd. (Geranium hispidum, Linn. f.). 

 Woody at base but herbaceous upward, 2-3 ft., much 

 branched, hairy and glandular: Ivs. long-stalked, hispid 

 on both surfaces, 4-5 in. across, 5-7-lobed, the lobes 

 acuminate and unequally sharp-toothed and more or 

 less lobulate; stipules cuspidate: fls. panicled, small, 

 white to carmine; calyx-tube shorter than pedicels, the 

 segms. lance-acuminate; petals about twice longer than 

 sepals. An old cult, plant. 



28. Ridula, L'Her. (P. muUifidum, Salisb. Geranium 

 Radula, Cav. G. revolutum, Jacq. f .) . Fig. 2848. Differs 

 from P. graveolens in the narrower divisions with revo- 

 lute margins of the Ivs.: the Ivs. are deeply palmately 

 parted, the lobes narrow linear and pinnatifid, all 

 rough-hispid on the upper surface and soft-pubescent 

 beneath: fls. small, pale purple, with dark streaks, the 

 peduncles short and hispid and about 4-5-fld., fls. pedi- 

 cellate; calyx-tube short, the lobes or sepals setose 

 and glandular. B.M. 95. Does not appear to be in 

 the trade in a pure form, but the narrow-lvd. rose 

 geraniums are probably hybrids between this and P. 

 graveolens. 



29. denticulatum, Jacq. (Geranium denticulatum, 

 Poir.). Fig. 2849. Much like P. Radula, but the lf.- 



lobes very denticulate and flat: Ivs. gla- 

 brous and viscid above, somewhat hispid 

 beneath; stipules ovate-lanceolate: fls. 

 34, subsessile, on short 

 hairy peduncles, lilac or 

 rose-purple, the 2 upper 

 petals toothed or 2-lobed 

 and with dark streaks; 

 calyx - tube short, the 

 segms. or lobes oblong, 

 mucronate and villous. 

 Plant weaker than P. 

 Radula. It has a bal- 

 samic odor. Perhaps it 

 has entered into the 

 garden forms of rose 

 geranium. Intro, into 

 England in 1789. 



BBBBB. Lvs. smatt, round-cordate, 3-lobed 

 half their depth and the margins 

 toothed or jagged. 



30. crispum, L'Her. Much branched 

 and very scabrous or rough, shrubby, 

 glandular: Ivs. 2-ranked, small and rigid, 

 short - stalked, cuneate, truncate or 

 slightly cordate at base, coarsely toothed, 

 more or less 3-lobed: fls. 2-3 on short 

 peduncles, violet, the lower petals nar- 

 row; calyx-tube glandular and roughish, 

 shorter than the pedicels, the lobes or 

 sepals oblong and acuminate. A neat 

 strict-growing plant with lemon-scented 

 2849 Pelargon- foliage. Probably not in genera) cult, 

 ium denticulatum. n 9 w m a pure form. Variable in the 

 wild. Var. latifdlium, Harv., Figs. 2850,
