LIMNOCHARIS 



Ivs. arising from bracted nodes, both long-stalked : fls.

 ably like LinnunitheniHm >i itniphoides. Grows well in an 

 aquarium or in shallow water. Continuous bloomer. 



emargrinftta, Humb. & Bonpl. (L. PJumieri, Rich. L. 

 fldra, Buch.). Stouter: Ivs. long-cordate-ovate, dock- 

 like, standing out of the water : fls. on long-winged 

 stalks, the yellow petals much contracted below : car- 

 pels 15-20, scarcely cohering. S. Amer. B.M. 2525.— 

 Less frequent than the last. 



The culture of Limnocharis Eumboldtii is of the 

 simplest. When grown in tubs, fill the latter two-thirds 

 full of moderately rich soil, covering with .sand and fill 

 up with water. Two or three plants planted in the cen- 

 ter will, in a short time, furnish the tub with its bright 

 glossy green Ivs. and numbers of its bright cheery yel- 

 low fls., which continue late in the season. In natural 

 ponds, planted on the edge the plants grow very rapidly, 

 and spread over a large surface of water. In artificial 

 ponds, plant in tubs or boxes and place in shallow wa- 

 ter or stand the tub or box on some stand, allowing 6-9 

 inches depth of %vater.

Limnochariti emarginata, or L. PJumieri, is entirely 

 distinct from the preceding. The light green oblong, 

 blunt Ivs. are very characteristic and ornamental ; petiole 



LINARIA 



triangular. 1-2 in. high: the fls., produced on a scape, 

 are pale yellow bordered white. Seed is produced very 

 freely, and as the seed matures the scapes fall to the 

 water, the seed ripens and sinks to the bottom, and 

 where grown out-of-doors, grows freely the following 

 season. The flower-scape, as soon as it rests on the wa- 

 ter, throws up a shoot, which produces another plant in 

 a short time, which again produces flowers, seeds and 

 shoots, and so on. The plant may be grown in pots or 

 tubs or planted out in shallow water in early summer.

LINABIA (Linnm, the flax, which the Ivs. of some 

 species resemble). ScrophulariAceae. Low herbs, some- 

 times subshrubs, of 130-150 species, widely distributed 

 in extra-tropical regions, several species cult, for the 

 oddly-irregular fls. and olhers for the festooning foliage. 

 Lvs. alternate, or sometimes subverticillate, in the 

 erect-growing species mostly narrow and entire : fls. 

 solitary in the axils, or in terminal racemes, yellow, 

 white, blue or purple ; corolla personate or grinning, 

 2-lipped, usually 1-spurred at the base (in rare or so- 

 called Peloria states 5-spurred); stamens 4, ascending 

 in 2 pairs, slender; style 1: fr. a dry capsule, opening 

 by slits or pores near the summit. 



Occasionally the fls. of the common toad flax (Linaria 

 vulgaris) are regular. When Linnceus discovered this 

 form, he took the plant to be of another kind and made 

 for it the genus Peloria. This word Peloria is now used 

 generically for the regular state of any normally irregu-

lar flower. Such monstrosities occur now and then, 

 particularly in the Scrophulariaceae. 



In America, Linarias are little known as garden plants, 

 although they are worthy greater attention. They are 

 of two general classes,— the hardy perennials and the 

 annuals. The perennials are prop, by seeds and by 

 division, usually the latter. All the species are of easiest 

 culture in any ordinary soil and exposure, and are largely 

 able to shift for themselves when once established. The 

 annuals may be started indoors ; or in warm situations 

 they may be sown where the plants are to stand.

CymbaUria, Mill. Kenilworth Ivy. Mother-of- 

 TufMSANiis. Fig. 1295. Perennial tender glabrous herb, 

 but snwiiig itsi'lf freely from seeds, long-trailing and 

 rooting at the joints: lvs. cordate-orbicular or reniform, 

 5-7-rounded-lobed, on slender stalks longer than the 

 blades: fls. solitary in the axils, on slender stems, small 

 but pretty, lilac-blue with a yellowish throat: capsule 

 globular, splitting from the top. Eu. — It sometimes has 

 white fls. There is also a variegated-lvd. variety. The 

 Kenilworth Ivy is one of the most familiar of traileis 

 on greenhouse bottoms and in odd comers; also as a 

 trailing basket plant in greenhouses and dwelling houses. 

 It is of the easiest culture, particularly in a moist and 

 partially shaded place. Prop, by division of the long 

 stems, or by seeds. It will not stand frost, but the plant 

 will spring up vear after year from seed, becoming es- 

 sentially annual. It has become established in the open 

 in many parts of the East. Continuous bloomer. A 

 good basket plant tor poorly lighted places.
