the year, and the decayed flower spikes. In dry gravelly, or 

 poor soil its flowers have a more powerful odour, and the 

 severity of our winters has little effect on it ; while in rich 

 garden soil, although it grows strongly, it is apt to be killed, 

 and the flowers have less perfume. 



True Lavender. Fl. July, Sept. Clt. 1568. Shrub 1 to 2 

 feet. 



6 L. SPICA (D. C. fl. fr. 5. p. 397.) leaves oblong-lanceolate, 

 somewhat spatulate, quite entire, narrowed a long way at the 

 base, with somewhat revolute margins, hoary on both surfaces ; 

 spikes somewhat interrupted; whorls G-10-flowered ; floral 

 leaves lanceolate, or linear, all fertile : upper ones shorter than 

 the calyxes ; bracteas linear-subulate, shorter than the calyxes.

 the region of the Mediterranean. L. spica, ft, Lin. spec. 800.

 2. Park, theatr. p. 73. f. 1. Calyxes bluish. Corollas blue, 

 rarely white. Habit of L. vera, but more humble, and the 

 aspect more hoary ; the leaves at the base of the branches more 

 crowded ; the spikes more dense and shorter : the floral leaves 

 different in form, and the bracteas present. The flowers of both 

 this and the preceding have a fragrant, agreeable smell, and 

 a warm, pungent, bitterish taste ; and this species yields by dis- 

 tillation thrice as much essential oil as the preceding ; hence in 

 the southern parts of France, where both kinds grow wild, this 

 only is used for the distillation of what is called oil of spike. 



Spica, or Broad-leaved Lavender. Fl. July, Sept. Clt. 1568. 

 Shrub 1 to 2 feet.

 ovate, acutish ; spikes elongated, slender, usually by threes, 

 hoary ; flowers solitary, opposite. (7 . G. Native of the 

 Canary Islands, on rocks by the sea-side. Jacq. icon. rar. 1. t.

 pilose ; leaves bipinnate : lobes entire, bluntish ; floral leaves 

 ovate-lanceolate, very acute ; spikes elongated, slender, branch- 

 ed ; flowers solitary, opposite. T? . G. Native of the Canary 

 Islands. L. Canariensis, Mill. diet. no. 4. L. elegans, Desf. 

 hort. par. p. 71. Mirb. ann. mus. 15. t. 5. f. 5. Comm. rar. 

 t. 27. This differs from L. pinna t a in its superfices being 



green, not hoary, in the stem being pubescent at the base, in 

 the leaves being more deeply cut, in the segments being nar- 

 rower, in the spikes being usually 5 together, longer, and more 

 loose, and in the floral leaves being more acute. Corollas pur- 

 ple, rarely white. 



Soulhcrnnood-like Lavender. Fl. June, Sept. Clt. 1699. 

 Shrub 1 to 2 feet. 



10 L. MULTIFIDA (Lin. spec. p. 800.) green, pilose ; stems 

 leafy; leaves bipinnatifid : lobes rather cuneated, acute : floral 

 leaves cordately dilated, acuminated, about equal in length to

 Native of the South of Europe, and North of Africa, in the 

 region of the Mediterranean. Barrel, icon. 795. Bauh. hist. 

 3. p. 281. f. 2. Lob. icon. 432. Very nearly allied to the 

 preceding, but differs in the spikes being shorter, and usually 

 simple, in the floral leaves being broad, and villous outside, and 

 in the calyxes being tornentose, and in the peduncles being one- 

 half shorter. Corollas purple, rarely white. 



Mullifid-teaved Lavender. Fl. July, Sept. Clt. 1597. Shrub 

 1| foot.

 246.) hairy ; stems strict ; leaves pinnate : segments linear, 

 entire, or a little cut ; floral leaves membranous, about equal in 

 length to the calyxes ; spikes slender ; flowers solitary, oppo- 

 site. Jj . ? G. Native on Mount Sinai, N. Bove. This 

 species appears intermediate between L. multtfida and L. 

 coronopifblia, but differs in hairiness, in the stems being more 

 leafy, in the spikes being more dense, and in the floral leaves 

 being larger. 



Donny Lavender. Shrub 1 to 2 feet. 



12 L. CORONOPIFOLIA (Poir. diet. 2. p. 308.) glabrous; stems 

 nearly naked ; leaves pinnate : segments linear, entire ; floral

Cult. All the species of Lavender are of easy culture and 

 propagation, increasing readily either by seeds or cuttings. L. 

 vera and L. spica are the only truly hardy species, all the 

 rest requiring the protection of a greenhouse, or frame during 

 winter. The L. vera and L. spica abide longer in a dry, 

 gravelly, or poor soil, than in a rich earth, although in such
