PELARGOXIUM 



to gardeners as P. odoraliim. It is a neat and worthy 

 plant, and showy when in flower. It has a lemon or 

 palm scent. The variety known as Lady Mary is of this 

 Kroup. 



B. aiipules I'eiy minute and adnate. 

 10. exstipaUtnm, Ait. Resembles P. crispum in 

 habit and foliage : Ivs. round-ovate, small, velvety, 

 about 3-lobed, the lobes cut-toothed or lobed: peduncles 

 slender, with very small bracts: fls, small, white, with 

 short spatulate petals. — Lvs. about K in. across, with 

 odor of pennyroyal. Appears not to be in the trade, at 

 least not in a pure form. 



AAAA. Plant with a short and thick more or less 

 fleshy stem or caudex, from which arise slender 

 branches, the lvs. long-stalked and reniform or cor- 

 date and obscurely lobed: stamens 6 or 7. (Cor- 



a, Curt. The fleshy caudex armed with 



persistent spine-like stipules : lvs. white-tomentose, 



cordate-ovate and obtuse, about 3-5-shaUow-lobed :

21. odoratissimum, Ait. Nutmeg Geranium. Pig. 

 1710. Stem or caudex very short, throwing up many 

 slender and weak soft-pubescent branches: lvs. very 

 long-stalked, soft, round-cordate and very obtuse, ob- 

 scurely 3- or more-lobed, the margins dentate-creuate : 

 peduncles long and borne opposite the lvs., 5-10-fld. : fls. 

 small, white, the petals about twice longer than the 

 calyx-lobes.— A common plant, cult, for its pleasant- 

 scented foliage. The plant known to gardeners as P. 

 fragrans is either this species or a close derivative 

 from it. 



AAAAA. Plant with short stem and tuberous roots, the 

 lvs. pinnate or pinnately parted, the fls. in manif. 

 fid. umbels. [Polyactium.) 



22. triste, Ait. Stem or caudex very short, succuloiit : 

 lvs. large, 2-3-pinnatcly compound pubescent, the ulti- 

 mate teeth gland-tipped: calyx-tube long and stalk-like. 

 much exceeding the pedicel, the lobes half as long as 

 the petals: fls. brown-yellow with dark spots. B.M. 

 1C41.— A well-marked species, occasionally ofi'ered in 

 the trade. 



23. guinquevulnemm, Willd. Somewhat shrubby at 

 base, sparingly branched, hirsute : lvs. 2-pinnatifld 

 with linear toothed segments, the stipules broadly cor- 

 date and mucronate: fls. purple, scentless, the petals 

 obovate, velvety and pale-edged; calyx-tube as long as 

 the pedicels, somewhat hairy, the lobes obtuse. — f)nce 

 offered by Saul.

24. fiilgidiun, Willd. Stem shrubby, densely pubes- 

 cent: lvs. pinnately 3-parted, silky on both sides, the 

 central segments 3-lobed, all deeply toothed: peduncles 

 usually branched, many-fld. : fls. small, bright scarlet, 

 the petals obtuse; calyx-tube conspicuously swollen at 

 the base and again just underneath the flower, thrice as 

 long as the pedicel, the lobes linear-obtuse. — Not now 

 seen in its pure fomi, but it is probably a remote parent 

 in various small-flowered scarlet Geraniiuns.
