PELARGONIUM 



to gardeners as P. oilornliim. It is a neat anil worthy 

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

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

 group. 



B. Stipules very minute and adnate. 

 19. ezBtipul^tum, 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 H 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. tong-stalked and reniform or cor- 

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



lusi

20. echinjktam, Curt. The fleshy caudex armed with 

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

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

 calyx downy, the tube sev- 

 eral times longer than the 

 ^ , calyx-lobes: fls. white, with 



a spot near the center (vary- 

 ~ 1*^.", ing to all purple), the petals

21. odoratissinmm, Ait. Nctmeg 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-crenate: 

 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 pinnntely parted, the fls. in many- 

 fid. umbels. (Polyactium.) 



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

 lvs. large, ■2-3-pinuately 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. 

 1641.— A well-marked species, occasionally offered in 

 the trade. 



23. quinquevulnerum, Willd. Somewhat shrubby at 

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

 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. — Once 

 offered by Saul.

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

 cent: ivs. 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 form, but it is probably a remote parent 

 in various small-flowered scarlet Ge 



FELEC^FHOBA (Greek, hatchet -bearing; from au 

 alleged resemblance in the tubercles). Cactdceie. 

 Hatchet Cactus. Stems globular, short-cylindric or 

 clavate, small, often cespitose: tubercles strongly com- 

 pressed from the sides; areolae very long and narrow, 

 bordered on each side by a row of about 20 very short, 

 appressed comb-like spines: fr. naked. A genus of 2 

 species closely allied to Mammillaria. 



asellii6Tmis, Ehrb. (from a fancied resemblance to 

 Asellus, the wood-louse). Fig. 303, Vol. I. Juice watery: 

 tubercles ashy green, more or less deeply grooved to 

 the woolly axil; spines not projecting beyond the mar- 

 gin of areola: fls. purple with paler sepals: fr. near the 

 center, red. Nuevo Leon and San Luis Potosi, Mex.

FELICAN FLOWEB. Aristolochia grandiflora. 



FELLfflA (Greek, pellos, dusky; from the usually 

 dark-colored leaf-stalks). Polypodiicea. A genus of 

 small, rock-loving ferns, with the sori at the ends of 

 free veins forming a mostly continuous marginal band 

 around the segments and covered by the more or less 

 changed margin of the segments. Most species thrive 

 best on limestone rocks.
