corditta. Very slender, 3-10 in. high : Ivs. cordate- 

 ovate, nmcronate: raceme 1-2 in. long, with 4-20 minute 

 purpli.sh fls. June-Aug. lu moist woods, Nova Scotia 

 to Alaska and Ore., south to N. J.; Eu. B.B. 1: 473. 

 Heinrich Hasselbring. 

 LITH0SF£RMUM (Greek, rock seed: the seeds like 

 little stones). Burraqhii'iceie. This includes a few low- 

 growing hardy herbaceous perennials of minor impor- 

 tance. The best known is L. 

 prostratiim, a rock-garden 

 trailer, which bears numer- 

 ous leafy spikes of blue fls., 

 each about % in. across, from 

 early summer to autumn. 



1303. Puccoon,— 

 Lithospermum canescens (X ---i). 



The common Gromwell, L. officinale, is rarely cult, as 

 a medicinal herb. The rest are procurable from dealers 

 in native plants. Seeds of the Gromwell and the western 

 species are procurable, and plants of the other kinds. 

 i. prostrahtm is said to be prop, only by cuttings of the 

 previous year's wood; L. muUiflorum by cuttings of 

 young shoots. The kinds with red roots yield a dye. 



Lithospermum has about 40 species in extra-tropical 

 regions: herbs or subshrubs, rough, silky, or bristly: 

 Ivs. alternate: fls. white, yellow, bluish or violet; calyx 

 5-parted; corolla funnel- or salver-shaped, 5-lobed; sta- 

 mens 5, fixed to the tube: ovary 4-lobed. 



A. Color of fls. blue or purplish. 

 B. Habit trailing: tube of corolla den.iely hairy, thrice 

 as long as the calyx. 

 prostri.tum, Lois. Gentian Blue Grojovell. Sub- 

 shrub ; Ivs. lanceolate-linear, margin somewhat revolute : 

 tube of corolla pubescent outside, densely villous at 

 apex. S. Eu. This is presumably the plant in the trade, 

 since L. prostratum, Buckl., is a white-fld. annual 

 properly called i. Matamorense. However, L. prostra- 

 turn, Lois., is referred by Index Kewensis to L. fruti- 

 cos»«i, which see. Gn. 45, p. 135. J. H. III. 32:475. 



BE. Unlit erect: tube of corolla not hairy. 

 fruticdsum, Linn. Distinguished as above by DeCan- 

 dolle. and apparently more of a shrub, with the leaf 

 margins decidedly revolute. S. Eu. — Not cult. 



AA. Color of fls. pale yellow, yellow or orange. 

 B. Size of fls. small: tube about as long as the calyx: 



roots not red. 

 c. Inflorescence sparse : throat of corolla crested with 

 appendages. 

 oJHcinUe, Linn. Gromwell. Much branched, 2-3 ft. 

 high : Ivs. lanceolate or ovate-lanceolate, 2 in. or less 

 long: fls. dull white. Along N. E. roadsides, but natu- 

 ralized from Eu. 



cc. Inflorescence dense: throat of corolla nearly devoid 

 of appendages. 

 pildsum, Nutt. Mostly unbranched, 1 ft. high: Ivs. 

 linear and linear-lanceolate, 2-4 in. long: fls. dull green- 

 ish yellow, crowded in a leafy thyrse. Western N. 

 Amer. 

 BB*. Size of fls. large, showy: t}ihe of corolla much 



longer than the calyx: roots red, long and deep. 



c. Floral leaves reduced to bracts no longer than the 



calyx. 



multifldrum, Torr. Height 1-2 ft.: Ivs. linear: fls. 



light yellow, spicate. Rocky Mts. to W. Tex. 



ci;'. Floral leaves much longer than the calyx. 

 D. Tube of corolla %~^ times as long as the calyx: 



crests of throat little if at all projecting or arching. 

 e. Fls. nearly without pedicels: glandular ring at the 

 base naked. 

 can6acens, Lehm. Puccoon, of the Indians. Red 

 Root. Indian Paint. Fig. 1303. Height 9-12 in. or 

 more: fls. orange. Plains and open woods, in sandy 

 soil, upper Canada to Ala., west to Ariz. B.M. 4389. 



EE. Fls. mostly pedicelled : glandular ring at base 

 uithin bearing 10 very hirsute lobes or teeth. 

 hirtum, Lehm. Height 1-2 ft.: fls. bright orange. 

 Pine barrens, Mich, to Fla. and Colo. 



DD. Tube of corolla 2-4 times as long as the calyx • 

 crests of the throat conspicuous and arching. 

 angUBtifblium, Michx. Fig. 1304. Height 9-12 in. or 

 more: Ivs. all linear: fis. of 2 sorts, the earlier and con- 

 spicuous kind bright yellow, with corolla tube 1 in. or 

 so long, later ones and those of the more dift'usely 

 branching plants with inconspicuous pale corolla, with- 

 out crests in the throat and probably cleistogenous. 

 Apparently all grades between early large fls. and late 

 small ones. Prairies. D. M. Andrews says it has pale 

 cream fls. Var. longiJldnim (i. longifldrum, Rort.,I). M. 

 Andrews) is saiil to grow 1 ft. high, with larger, pale 

 lemon lis. and comes true from seed. Grows wild in 

 Colo. w. M. 



LITTSA.. iice Agave. 



LITHRffiA 1 Chilean name). Anacardidce(T. A genus 

 of small Simth .American trees related to Rhus, and by 

 Beiitham and Hooker included in that genus. The plant 

 cult, by some under this name seems not to be true to 

 name, as it is a tree with undivided Ivs., while the true 

 plant is. as hrub with 1-3 pairs of Ifts. and odd pinnate.
