 muitipunciata, HotTmgg.^L. Uroussonettii. — L. Fancici, Hort. (not

 clusters. Spain. T H R 



LINDELOFIA (Frieilrich von Lindelof, a German 

 patron of botany). Boraginacea'. Two species of erect 

 liartly herbaceous perennials from the high Himahiyas, 

 onecuhivated for t he flowers resembling forget-me-not. 



This genus hiis the habit and nutlets of Cynoglossum, 

 but the stamens of Cynoglossmn are included, while 

 those of Lindelofia are exsertcd: Ivs. radical and cauline, 

 the latter alternate and ovate to linear-lanceolate: fls. 

 blue or purple, often very dark, in long dense racemes; 

 sepals somewhat enlarged in fr.; corolla with cylindri- 

 cal tube and cone-like scales in the throat, the lobes 

 obtuse; stamens .5, with large linear-oblong anthers; 

 ovary 4-lobed: nutlets with hook-tipped bristles. 



longiflora, Giirke (L. speddhilis, Lehm. Cynoglos- 

 sum longiflbrum, Benth.). Pilose: Ivs. oblong-acumi- 

 nate, the upper ones heart-shaped or clasping at the 

 base: fls. deep blue; tube J^'in. long and lobes shorter. 

 B.R. 26:50. J.H. III. 31:2-3.5. Var. afghanica, Hort., is 

 offered, 1 ft., of spreading habit. G.W. 10, p. 90. — 

 The species is variable, particularlj- in size of corolla. 

 It usually grows about 2 ft., flowering freely in May 

 and later. The racemes are about 6 in. long, and have 

 8-12 fls. The plant is likely to be winter-killed unless 

 given a sheltered place, good drainage and winter cov- 

 ering. It is not fastidious as to soil. Easily prop, by 

 division. It seeds freely and flowers the second year 

 from seed. Wilhel.m Miller.

LINDEN: Tilia. 



LINDENBERGIA (J. B. W. Lindenberg wrote on 

 the liverworts, 1S29). Scroplndariacese. About 16 

 annual or perenni;il herbs of trojiical or warm parts of 

 Asia and Afr., differing from Nlimulus in having a 

 campanulate rather than tubular calyx and the anther- 

 cells separate: corolla 2-lipped, the tube cylindrical; 

 upper lip short and broad, emarginate or lobed; lower 

 li]) larger. 3-lobed and spreading; stamens 4, didyna- 

 nious, included: caps, oblong or ovoid, dehiscent: plant 

 decumbent or ascending, .sometimes woody at base, 

 with opposite dentate Ivs. (or the upper ones alternate) : 

 fls. nearly sessile, solitary or in terminal racemes or 

 spikes, the bracts leafy. L. grandiflora, Benth., has 

 recently been mentioned in horticidtural literature 

 abroad. It is a good greenhouse plant in England, with 

 yellow fls.: soft-hairy, somewhat scandent: Ivs. ovate, 

 acuminate, coarsely serrate: fls. 1 in. long, in terminal 

 leafy spikes. Himalaya, to 6.000 ft. altitude. B.M. 

 773.S. G.C. 111.32:213; 53:27. G.M. 45:610; .56:41. 

 G. 24:671. — Mentioned sometimes as annual, but it is 

 perennial in cult. It is a valuable winter-blooming 

 plant, keeping in good condition 3 months, and may 

 be grown in compact bu-shy form by being cut back.

LINDERA: Benzoin. 



LINDSAYA ("Archibald Linds.ay, early English 

 botanist). Sometimes spelled Limlssra. Pnlypndincese. 

 About thirty species of tropical ferns, of both 

 hemispheres, none of which is advertised in Amer. 

 They are verj' difficult of cultiv.ation. aiid are appar- 

 ently adapted only as fancier's plants. ,Schiici<l('r. in 

 his "Book of Choice Ferns," .says they i-sually ilie soon 

 after importation, even if .apj)arently ir good c(mdition 

 on arrival. In their native habitat, he says, these 

 ferns usually creep about in poor, stf ny soil, which is 



frequently drenched and washed away by rain. They 

 net'd a high temperature and humid atmosphere. 

 Some success has been attained by placing lindsayas 

 in pots nearly filled with crocks, in which they are 

 firndy held by two or three pieces of turfy loam, 

 and by imitating in other ways the natural conditions 

 described above. 



LINNiEA (named after Linnajus, at his own request; 

 it was his favorite flower). Caprifoliaccse. Twin- 

 Flower. Ornamental hardy plant grown sometimes 

 for its delicate pink or puriilish flowers. 



Evergreen trailing subshrub: Ivs. ojiposite, small, 

 crenate, jjetioled, without stipules: fls. in pairs on 

 slender upright peduncles; calyx 5-parted; corolla 

 campanulate, 5-lobed; stamens 4; ovary 3-celled: fr. 

 dry, inilehiscent, 1-seeded. — Only one species in the 

 colder regions of the northern hemisjihere. There is an 

 interesting monograph of this variable species by Wit- 

 trock in Acta Hort. Berg, 4, No. 7, 187 pp., 13 pi. 

 (1907), where about 150 varieties are described and 

 figured. 



The twin-flowers are half-woody plants with trailing 

 slender thread-like stems, small, usually roundish per- 

 sistent leaves and slender-stalked, nodding, pinkish or 



2179. Linnsea borealis. ( X '4) 



nearly white, campanulate twin flowers. They are 

 hardy North and are graceful, dainty plants for rock- 

 eries, preferring a shaded moist position and porous, 

 peaty or humous soil. Propagation is usuallj' by division 

 or by cuttings of soft or half-ripened wood under glass. 



borealis, Linn. Fig. 2179. Sts. slender, slightly 

 pubescent: Ivs. short-pctioled, roundish or obovate, 

 with few crenate teeth, usually ciliate and with scat- 

 tered hairs above, J-i-J^in. long: fls. pedicelled in 2'8 

 at the top of slender, upright peduncles; corolla rose- 

 colored or white, H-'ain. long, fragrant, in the typi- 

 cal form campanulate, with, the constricted portion 

 at the base much shorter than the calvx. June-Aug.

 1910:138. Var. americana, Rehd. {L. nmcricana, 

 Forbes). Differs chiefly in the corolla being distinctly 

 tubular at the base, the tubular (lart exceecling the 

 calyx: Ivs. usually glabrous, but ciliate near the base. 

 N. Amer., Lab. to Alaska, in the mountains south to 

 Md. and Calif. B.B. (ed. 2) 3:276. Var. longiflora, 

 Torr. (L. kmgiflbm, Howell). Fls. more funnelform, 

 J^^in. long or slightly longer; peduncles 2-3 in. long: Ivs. 

 generally somewhat larger. Wash, to Calif. A var. 

 major is listed. In Fig. 2179, (he two large Ivs. in the 

 foreground do not l)elong tci Linna'a.
