 Hort. Ji. (/raiidifldrum, var. albifldrum, Hook.). This 

 differs from var. Watsoiii only in being pure wliite, 

 with a delicate greenish cast. B.M. .5714. F.S. 20:2117.

BB. Style not diiHded. 



citrinum, Wats. Lvs. mottled: stem l-.3-fld. : petals 

 broad, strongly recurved, light yellow, orange at center, 

 the tips becoming pink. 



HSnderaonii, Wats. Lvs. mottled in dark brown : 

 petals strongly recurved, pale purple, with a very dark 

 purple, almost black, center. G.F. 1:317. O.C. 111.

purpuriscens, Wats. Lvs. not mottled but shaded in 

 dark metallic tints: small, spreading fls. crowded in a 

 raceme, light yellow (almost white), center orange, be- 

 coming purplish. — The smallest of our Erythroniunis. 

 Properly an alpine. 



Hdwellii, Wats. Lvs. mottled: scape 1-3-fld. : fls. pab^ 

 yellow with orange base, becoming pinkish. — Of ttie 

 Pacitic coast Erythroniums, this alone is destitute of

EEYTHR6XYLUM {Greek, red wood: true of some 

 species). Liniteeir. Cooa. The Cocoa plant, the lvs. of 

 which are of vast importance in medicine, can be grown 

 in the extreme south of Florida and California, and is 

 rarely cult, under glass in the North for its economic 

 interest. It is a shrub 5-6 ft. high, w^th rusty brown, 

 slender branches, on the extreme tips of which the lvs. 

 are borne. Below the lvs., on the wood of the preceding 

 year, which is reddish, clusters of 3-5 yellow 5-lobed 

 fls. a quarter of an inch across spring from the protec- 

 tion of the small scales that line the branchlets, and 

 which are colored like the bark. The native country of 

 the Coca being still uncertain, itis necessary forpurposes 

 of description to take as the type the earliest described 

 form, which happens to be a Peruvian one, named by 

 Lamarck £Jrijtkroxylu7n Coca, and tigured in the Botani- 

 cal Magazine 1894, plate 73.34. The lvs. of this form are 

 about 2% in. long, oblong-obovate, tapering to a short 

 stalk, rounded at the apex, the midrib extending beyond 

 into a short, sharp point. 



Cocoa is grown commercially on a large scale through- 

 out South America. Peru produces fifteen million 

 pounds of the dried leaf every year, Bolivia half as 

 much, and the rest of South America very much more. 

 The lvs. are chewed to prevent hunger and fatigue. 

 Dr. H. H. Rusby, of New York, in the Therapeutic 

 Gazette, says, "The effects of Cocaine as a nerve stimu- 

 lus applied to intellectual and emotional activity are 

 ruinous. It takes away appetite, abolishes the sensa- 

 tions of hunger and thirst, lessens waste during exer- 

 tion, and decreases the exhaustion of ill-fed laborers 

 and travelers. Beyond this. Cocaine has no supporting 

 or nourishing power whatever, and its essential action 

 is enfeebling. Every attempt made to support by it 

 athletic competition has resulted in failure or even 

 disaster." Cocaine is an excellent anesthetic, and is 

 particularly useful in operations on the eye. Coca 

 should not be confused with Cocoa and Cacao, which 

 are discussed under Theobroma. The literature of 

 Coca, from every point of view down to the year 1889, is 

 reviewed in the'Kew bulletin for that year. -^^ ji, 



ESCALLONIA (Escallon was a Spanish traveler in 

 S. Amer.). SaTAfragaceo!. About 40 South American 

 evergreen shrubs or trees, with scattered entire or ser- 

 rate, ovate or lanceolate lvs , viscid branches, strong- 

 odorous fls. in terminal racemes or panicles: petals 5, 

 linear-spatulate ; stamens 5 ; anthers ovate-oblong ; 

 style simple, the stigma capitate and 2-3-lobed: ovary 

 2-3-Ioculed. A few species have been introduced in the 

 S., chiefly in S. Calif. They are of easy culture; rapid 

 growers. Some of them will no doubt prove half hardy 

 as far north as Washington. Spring and summer. 



Montevid^nsis, DC. (E. floribnnda, Hort.). Nearly 

 erect bush, branches cylindrical : lvs. 2-1 in. long, elliptic 

 or linear-oblong, obtuse or nearly so, narrowed into a 

 distinct petiole, minutely dentate: fls. white, Jain. 



across, in a large, terminal panicle-like cyme. B.M. 

 6404. B.B. 17:1467. 



pulverul6nta, Pers. {E. Tierteridna, DC). Shrubs, 

 hairy all over : lvs. elliptic and obtuse, serrate : fls. 

 white, in erect, terminal racemes: branches trigonal. 



virg^ta, Pers. {E. PhiUppidna, Mast. E. virgdta, 

 var. PhilippiUna, Engl.). Half-hardy shrub south of 

 Washington, with rod-like light brown branches : lvs. 

 nearly sessile, not glandular nor odorous, linear or 

 oblong-spatulate, serrate : fls. white, small, in dense 

 racemes terminating the branchlets. 



Organ6nsis, Oardn. Half hardy S., 2-5 ft., branches 

 red and angled : lvs. elliptic or oblong, crowded, serrate, 

 glossy: fls. pink, in close, terminal clusters. B.M. 4274. 

 — Excellent. 



rtihra, Pers. Twiggy shrub, glandular-pubescent: lvs. 

 rather small, obovate-lanceolate, sharp-toothed : fls. 

 long-tubular, red, in short, terminal clusters. B.M. 2890

ESCHSCHOLZIA (J. F. Eschscholz, of Kotzebue's 

 scientific expedition). Papaverdceti?. About a dozen 

 low, pale or glaucous herbs, annual or perennial, with 

 dissected, alternate lvs., and large, showy yellow or 

 whitish fls.; sepals 2; j^etals 4; stamens numerous; 

 stigmas 4—6: capsule long and slender like a silique, 

 1-loculed. The calyx forms a hood which is pushed ofi 

 over the bud as the petals expand (see detail at the left 

 in Fig. 780). The toiiis or receptacle (from which the 

 capsule arises) is pirominently widened or dilated.
