PELARGONIUM 



PELARGONIUM 



2843. Pelargonium corda- 

 tum. Leaves often are much 

 more cordate at base. ( X 1 A) 



deeply toothed, the terminal lobe oblong and pinnatifid ; 

 stipules acute, broadly cordate: peduncles usually 

 branched, many-fld.; fls. small, bright scarlet, the 

 petals obtuse; calyx-tube conspicuously swollen at the 

 base and again just underneath the fl., thrice as long as 

 the pedicel, the lobes linear- 

 obtuse; petals brilliant scar- 

 let with dark lines. Per- 

 haps not now seen in its 

 pure form, but it is probably 

 a remote parent in various 

 small-fld. scarlet geraniums. 

 Cult, in England as early 

 as 1723. 



AA. Plant either succulent, or 

 shrubby and slender, 

 the root branching: Ivs. 

 mostly cut or decom- 

 pound (rarely entire), 

 pinnately formed: petals 

 nearly equal, narrow- 

 spatulate; fertile stamens 

 7. (Ligularia.) 



4. exstipulatum, L'Her. 

 Shrubby, canescent: Ivs. 

 round-ovate, small, velvety, 

 about 3-lobed, the lobes 

 cut-toothed or lobed, the 

 lateral lobes small; stipules 

 adnate and very minute: 

 peduncles slender and few- 

 fld., with very small bracts; 

 fls. small, white, with short 

 spatulate petals. Lvs. 

 about Kin. across, with 

 odor of pennyroyal. Ap- 

 pears not to be in the trade, at least not in a pure form. 



5. artemisaefdlium, DC. (P. artemisioldes, Hort.). 

 Suffruticose, erect and slender, glabrous, nearly sim- 

 ple: Ivs. long-petioled, 2-pinnately parted, nearly 

 glabrous, the segms. linear-filiform and channeled; 

 stipules free, subulate: peduncles long, 2-3-fld.; fls. 

 white or blush; calyx-tube swollen at base, 2-3 times 

 as long as the lance-cuspidate segms., not ribbed; petals 

 about twice longer than calyx-segms. or sepals, spatu- 

 late or obovate, rounded at apex, more or less veined 

 and spotted at base. G.M. 54:629. 



II. Lvs. on the palmate order, although sometimes entire, 

 usually lobed (Nos. 6-31). 



A. Plant shrubby, or sometimes succulent and jointed: 

 Ivs. palmately nerved or lobed; stipules persistent 

 and either rigid or membranaceous: petals or 5, 

 the two uppermost broadly obovate and long- 

 clawed, very much longer than the lower 

 ones; fertile stamens 7. (Jenkinsdnia.) 



6. Endlicherianum, Fenzl. Herbaceous peren- 

 nial, 1-1 K ft. high, noteworthy in being W. 

 Asian: st. little branched, somewhat fleshy, 

 terete, pubescent: basal Ivs. more or less numer- 

 ous, glaucous, cordate-orbicular, broadly and 

 obscurely 5-lobed, lobes crenate-dentate, with 

 whitish appressed hairs; stipules lanceolate, 

 hairy: fls. many in the umbel, rose-colored; spur 



of calyx exceeding pedicel; upper 2 petals 2-3 times 

 longer than sepals. Asia Minor, Syria. B.M. 4946. G.C. 

 111.30:149. Gn. 60, p. 185. G.M.52:214. H.F.II.7:71. 



AA. Plant weak and usually trailing, the branches slender 

 and not succulent: Ivs. thick or fleshy and glossy, 

 lobed, mostly marginally peltate: infl. umbellate; 

 good stamens 7, 2 upper shorter; petals unequal. 

 (Dibrdchya.) IVY-LEAVED GERANIUMS. 



7. peltatum, Ait. (Geranium peltdtum, Linn.). Fig. 

 2839. Plant with slender-jointed more or less zigzag 



angled sts. which are glabrous or very nearly so (except 

 at the top): Ivs. glabrous or minutely pubescent, fleshy, 

 the petiole inserted just inside the margin at the base, 

 about 5-nerved and with 5 short wide mostly obtuse 

 main lobes and often with smaller minor lobes or angles 

 and notches, the margins very entire: peduncle very 

 long, originally 4-8-fld., but now bearing many greatly 

 modified fls., the calyx-tube slender and stalk-like, 

 often longer than the pedicel and 2-3 times longer than 

 the pointed nerved and mostly ciliate lobes ; petals twice 

 as long as calyx-lobes, red to white or purplish, the 2 

 upper ones erect and purple-blotched or striped, the 

 3 lower ones usually smaller and not marked and 

 separated from the upper as if the fl. were 2-lipped. 

 B.M. 20. Parent of the ivy-leaved geraniums, now 

 much unproved and varied. Prized for baskets. There 

 are forms with double fls. and colors of various kinds. 

 It is a most desirable plant and very floriferous in most 

 of the garden sorts. In the wild there are the following 

 forms: Var. glabrum, Harv. Calyx and foliage gla- 

 brous: fls. purplish pink. Var. scuta turn, Harv. (P. 

 scutdtum, Sweet). Calyx villous: Ivs. glabrous. Var. 

 clypeatum, Harv. (P. clypedtum, Steud.). Calyx and 

 Ivs. soft-pubescent. P. lateripes, L'Her. (P. hederse- 

 fdlium, Salisb.), has Ivs. cordate, not peltate. 



AAA. Plant woody or herbaceous, with slender sts.: Ivs. 

 very long-petioled, palmately 5-7-nerved, lobed or 

 cut; stipules free, ovate or lanceolate: petals unequal, 

 the two upper ones broad; fertile stamens 7, unequal. 

 (Eumorpha.) 



8. grandifldrum, Willd. Shrubby, glabrous and 

 glaucous: Ivs. long-stalked, strongly 3-7-nerved from 

 the top of the petiole, deeply 5-7-lobed, the lobes broad

2844. Pelargonium angulosum. From Dillenius' figure in 1732. 

 (One-half the size of the original plate.) No. 20.
