 129(i. Vif^orous perennial, spreading freely by under- 

 ground stems and in time forming large and persistent 

 patches: stems strict, nearly or quite simple, slightly 

 glaucous, 1-3 ft. high : Ivs. many, scattered, linear, 

 somewhat narrowed below: lis. in a terminal spicate 

 raceme, erect-spreading, witii hanging nectary spur,

 A.G. 1^: 4(>9.— Extensively naturalized, and commonly 

 regarded as a bad weed; but it infests cbieHy waste 

 places, and although ditKcuIt to eradicate it 

 does not spread very rapidly. Now and then 

 it appears as an ornamental plant. It is more 

 interesting to the general plant-lover than to 

 the gardener. A double-lid. form is figured in 

 G.C. 111. 18:554. The Peloria forms may have 

 5 spurs, or no spurs at all (K.H. 1851: 433).

 ft. Iiigh, branching: Ivs. narrow-ovate or the 

 upper ones lanceolate, somewhat cordate at 

 the base, nearly or quite Sfssile, entire: lis. 

 bright yellow, with deeper color on the palate, 

 in long wand-like terminal racemes. Mace- 

 donia.^Gn. 45:948. J. H. 111. .30:409. -A showy 

 plant, hardy, bearing its snapdragon-like tls. 

 most of the season. Perhaps a wiile-leaved 

 form of L. Dalmatica, Mill.

 less high, with weak and spreading flower 

 stems: Ivs. linear or lanceolate, mostly in

 an orange-colored palate, the straight or 

 slightly curved, sharp spur as long as the 

 corolla. Alps. F.S. 20:2128. G.C. II. 14:105.

LINDELOFIA (Friedrich von Lindclof, of 

 Darmstadt, a patron of botany). Horragin- 

 dcea/. Two species of hardy herbaceous per- 

 ennials from the Flimalayas, one of which is 

 cult. It grows l-ljv^ ft. high, and in June 

 and July bears racemes of drooping, odd- 

 colored fls. about three-fourths of an inch 

 long, with a pale blue tube and 5 deep rose 

 or purplish lobes. The racemes are about 

 in. long, and have 8-12 fls. The plant is likely 

 to be winter-killed unless given a sheltered 

 jdace, good <Iraiuage and winter covering. It 

 is not fastidious as to soil. Easily prop, by 

 division. It seeds freely and flowers the sec- 

 ond year from seed. 



Like Sfdenanthus, this genxis has the habit 

 and nutlets of Cynoglossum, but the stamens 

 of Cynoglossum are included, whilo those of 

 the other two genera are exsertcd. Solenan- 

 thus differs from Lindelofla in having a more 

 tubular flower, the lobes being relatively 

 shorter and erect or slightly spreading. 



spectdbilis, Lehm. Pilose : Ivs. oblong- 

 acuminate, the upper ones heart-shaped or 

 clasping at the base: racemes hractless. B.

LINDS.ffiA, or Lindsaya, is a genus of about 

 50 si)ccies of tropical ferns, none of which are 

 advertised inAmc-rica. Schnei- 

 der, in his Book of Choice Ferns, 

 says they usually die soon after 

 importation, even if apparently 

 in good condition on arrival. 

 In their native habitat, he says, 

 these ferns usually creep about 

 in poor, stony soil, which is fre- 

 quently drenclied and washed 

 away by rain. They need ahigh 

 temperature and humid atmos- 

 phere. Lately some success has 

 been attained by placing Lind- 

 Sfeas in pots nearly filled with 

 crocks, in which they are firmly 

 held by 2 or 3 pieces of turfy loam, and by imitating in 

 other ways the natural conditions described above. 



LINN.ffiA (named after LinnfGus, athis own request; it 



was his favorite flower). Caprlfolidcece. Hardy ever- 

 green trailing subshrub with opposite, small Ivs. and light 

 pink, campanulate, nodding fls. in pairs on slender up- 

 right stalks. A graceful, dainty plant for rockeries, pre- 

 ferring a shaded position and porous, peaty soil. Prop, 

 usually by division or cuttings of soft or half-ripened 

 wood under glass. Only one species in the colder re- 

 gions of the northern hemisphere. Calyx 5-pa.rted ; co- 

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

 fr. dry, indehiscent, 1-seeded. By some botanists Abelia 

 is united with this genus.
