ERYSIMUM 



ERYTHEA 



1418. Erysimum asperum. 



In general, no special difficulty is experienced with 

 erysimums. In Gn. 24, p. 462, it is said that E. och- 

 roleucum on level ground is likely to lose its lower Ivs. 

 and to perish on heavy soils in hard winters. It thrives 

 best when frequently divided, and may be propagated 



by cuttings. E.

 Biennial or perennial, probably usually perennial, erect 

 and leafy and finely pubescent, 1 ft. or less to 2 ft.

 reddish orange: pods standing out nearly at right angles, 

 constricted below the narrower style. Caucasus, 

 Afghanistan. B.M. 3757. P.M. 6:245. There are 

 compact and dwarf strains suitable for edgings (E. 

 Perofskianum nanum. E. nanum compactum aureum, 

 Gt. 46, p. 194. E. compactum aureum, Hort.). Seeds 

 may be sown at different times for succession. 



pulchellum, Boiss. (E. laciniatum, Boiss.). Perennial, 

 green, often cespitose, the st. ascending 2-6 in. or 

 more (even to 2 ft.): lower Ivs. oblong-spatulate, den- 

 tate or lyrate; upper Ivs. sessile, oblong or lanceolate, 

 dentate; Ivs. on the suckers lanceolate and often entire: 

 fls. medium, deep orange: caps, erect-spreading, slen- 

 der. Greece, Asia Minor. Used as rock-garden plant. 

 There are dwarf forms in the wild. 



ochroleftcum, DC. (E. rhseticum, DC. E. helveticum, 

 DC.). Perennial, 4-12 in.: sts. yellowish, creeping: 

 Ivs. oblong-lanceolate, dentate, usually more or less 

 hairy: fls. fragrant, pale yellow, the petals obovate. Eu. 

 Gt. 2, p. 162. Variable. Forms a turf on rocks and 

 mountains. 



E. Marschallianum, Andrz. Biennial, perennial, 6-8 in. high: 

 Ivs. lance-linear: fls. large, bright orange-yellow: used as an

 perennial, 6-8 in., forming a tuft: Ivs. deep green, narrow: fls. 

 golden yellow. Eu. WlLHELM MlLLER

ERYTHEA (one of the Hesperides, Daughter of 

 Evening). Palmdcese, tribe Cori/pheae. Palms with soli- 

 tary, often robust, spineless caudices, ringed at the 

 base, clothed above with dead leaf -sheaths. 



Leaves terminal, the younger ones tomentose in 

 some species, glabrous in others, orbicular, flabellately 

 many-parted, the lobes lacerated at the apex, inter- 

 mingled with fibers, infolded; rachis short; ligule long; 

 petiole stout, slender and arching in some species, 

 smooth or spiny along the margins: spadices usually 

 paniculate, long, white tomentose; branches stout; 

 spathes many, sheathing the peduncle, thick-coriaceous, 

 densely tomentose; bracts and bractlets distinct; fls. 

 pale: fr. globose or ovoid. Species 5, Mex. 



This small group of American palms includes E. 

 armata, which is known locally as the "blue palm," 

 and E. edulis, the latter commonly known as the 

 "Guadaloupe palm," from the fact that it has been 

 found in a wild state only on the island of Guadaloupe, 

 off the coast of Lower California. Erytheas bear much 

 resemblance to Brahea, the segments of the leaves 

 bearing whitish filaments. In the gardens of Santa Bar- 

 bara, the erytheas in a few years form very handsome 

 trees, but in less-favored latitudes they may be culti- 

 vated in the same manner as kentias or latanias, flour- 

 ishing in a night temperature of 50 to 55 when grown 

 in a rich and open soil and abundantly supplied with 

 water. 



A. Fr. more or less globose. 



B. Lvs. distinctly glaucous. 



armata, Wats. (Brahea armata, Wats. B. glauca, Hort. 

 B. Roezlii, Lindl.). BLUE PALM. Tall and slender, 40 

 ft. high: Ivs. very glaucous; petiole narrow, deeply 

 channeled, margined with numerous stout, more or less 

 hooked, slightly spreading spines; segms. 30-40, sub- 

 lacerate at the apex, slightly filiferous: spadix 18 ft. 

 long or somewhat less, sparingly branched: frs. red- 

 dish brown at maturity. Low. Calif. G.C. III. 20:425. 



BB. Lvs. green, not glaucous. 



edillis, S. Wats. (Brahea ediilis, Wendl.). St. 40-50 

 ft. high, 15 in. thick, with thick, corky bark: sheaths 

 fibrous; petioles stout, 1 in. 

 wide, plano-convex, unarmed on 

 the acute margins, fibrous-pubes- 

 cent or glabrate above; ligule 

 2-3 in. long, densely silky-tomen- 

 tose; blade 3 ft.; segms. 70-80, 

 at first tomentose, lacerate at the 

 apex and fibrous on the edges: 

 spadices numerous, 5-6 ft. long, 

 branched: fr. shining black. 

 Calif. R.H. 1893, p. 297; 1897, 

 p. 77. G.C. III. 13: 507; 22: 157. 



Brandegeei, Purpus. In nature 

 125 ft. high and having slender 

 trunk: petioles slender, armed 

 with recurved spines; Ivs. bright 

 shining green, composed of 10-12 

 frpnded, flabellate Ifts. : spadix 

 slightly branched: frs. as in E. 

 armata, but somewhat streaked. 

 Low. Calif. Gt. 52, p. 12. Intro, 

 by Franceschi in 1912. who says, 

 "Appears to grow much faster 

 than other kinds and is not less 

 hardy." 



AA. Fr. shaped like inverted 



pear. 



elegans, Franceschi. 

 Dwarfer and slower-grow- 

 ing than any other kind:
