 glabrous, 1-2 ft. tall: Ivs. linear and acute, alternate:

 Worthy hardy perennial, summer-blooming, often flow- 

 ering the lirst year from seed. 



L6wisii, Pursh (L. perinne, var. Liwisii, Eaton & 

 Wright I. The West American representative of the 

 above, and scarcely distinguishable from it except that 

 the Hs. are not heterogonous, pedicels more erect in fruit, 

 calyx nerves not evident. Fls. \% in. across, clear sky- 

 blue, very pretty. B.R. 14:1163 (as L. Sibiricum, var. 

 Lewisii). 



Austriacum, Linn. {L. perinne, var. Austrlacum, 

 Voss). Lvs. linear, punctate: fls. rather small, violet-

 flexed. Austria. — Hardy North, growing 1-2 ft. high and 

 blooming all summer. 



Narbonn^nse, Linn. One to 2 ft. high, forming a 

 spreading clump, glabrous and slightly glaucous, and 

 very handsome for rockwork : lvs. linear-lanceolate, 

 pointed, alternate: fls. 1% in. across, on slender pedicels 

 in loose panicles, azure blue, with white eye and white 

 stamens. Eu. Gn. 52, p. 401.— Blooms in late spring and

LiPAILlS {Greek, fat, shining). OrehidAeew. A large 

 genus, containing over 100 species, distributed over the 

 warm and temperate regions of the entire earth. The 

 plants grow erect, with stems in some species 1 ft. high, 

 bearing 1 or several lvs. and a terminal raceme of small, 

 rarely medium-sized fls. Herbs, terrestrial or epiphytic: 

 stems sometimes thickened at the base into a small 

 pseudobulb, sheathed by scales : lvs. few, broad, con- 

 tracted into .sheathing petioles: fls. whitish, greenish 

 yellow or purplish ; sepals and petals nearly equal, 

 linear, spreading; column long; lip nearly plane, often 

 with two tubercles above the base. 



L. liliifolia should be planted in well-drained soil; a 

 shady bank is preferable. Jj. Ztceselii delights in a wet 

 situation, just at the edge of the water.

LlPPIA (August Lippi, French traveler, 1678-1704). 

 Syn.,Aloysia. Verbendcea. The Lemon Verbena is an 

 old-fashioned favorite, with delightfully fragrant foli- 

 age, a sprig of which was often included in mixed bou- 

 quets. It is a low-growing, tender shrub, with long, 

 narrow, pointed, entire lvs., which are usually borne in 

 3's. In summer, it bears minute fls. in a delicate, pyra- 

 midal panicle, composed of many-flowered spikes, which 

 appear in groups of three at decreasing intervals along 

 the main axis. The Lemon Verbena comes from South 

 America, and in the North is deciduous. In northern 

 gardens it needs a winter overcoat of straw. In S. 

 Calif, it attains a large size out-of-doors. Full cultural 

 directions are given at the end of this article. 



The genus Lippia is botanically nearer Lantana than 

 Verbena, though the common forms of all three genera 

 are very unlike horticulturally. Some species of Lippia 

 have their spikes crowded into dense heads, like Lantana. 

 The drupe in Lippia is dry, but in Lantana it is often 

 .iuicy. About 90 species, chiefly American.la few African. 

 Shrubs, subshrubs or rarely herbs, hairy or not: lvs. 

 opposite or in 3's, rarely alternate, entire, toothed or 

 lobed, flat or wrinkled: calyx small, 2-4-cut; corolla 

 with a cylindrical tube, and 4 lobes. 



Under the name of L. repens, Franceschi introduced 

 into S. California in 1900 an interesting perennial 

 plant designed as a substitute for lawn grass in the 

 South. It makes a remarkably dense mat, and bears 

 numerous tiny flowers an inch or so above the ground. 

 The fls. are borne in a dense, bud-like head, covered 

 with many tightly overlapping bracts. The fls. appear 

 in rings, beginning at the base of the little head. 

 Franceschi writes of this plant that it thrives in any
