tinged green. Gn. 49, p. 470. Gng. 5:262. J.H. III. 

 30:231. Var. aurea, Hook. (L. aurea, Lindl.), peri- 

 anth bright orange-yellow. F. 1871:265. B.M. 5992. 

 "The varieties are connected by intermediate stages. 

 Several hybrids between L. pendnla and the varieties 

 of L. tricolor are in cult., the finest of which is L. 

 Cammi, Hort., which combines the bright yellow fls. of 

 L. aurea, with the habit of L. pendula." 



7. pustulata, Jacq. Lvs. lanceolate : fls. white or 

 faintly tinged red. B.M. 817. Perhaps synonymous 

 with No. 8. Var. violacea is cult. 



8. pallida, Ait. Lvs. strap-shaped : fls. white; outer 

 segments tipped green. B.M. 1372. 



9. unifdlia, Jacq. Differs from all described above in 

 having only one leaf, which is linear to awl-shaped, and 

 has a band of brown at the base: fls. white, or more or 

 less tinged with red or blue. B.M. 766. 



L. viridis, Thunb., is Dipcadi filamentosum, which is distin- 

 guished from the species of Lachenalia by having 3-6 Ivs., 

 which are linear: raceme very lax: fls. bright green. Cape. 

 In Dipcadi the outer segments usually have a tail, which is lack- 

 ing in Lachenalia; and the seeds of Dipcadi are strongly com- 

 pressed, while in Lachenalia they are obovpid or globose. D. 

 viride is distinguished from all other species in its genus by 

 the outer segments being falcate, 9-12 lines long, distinctly 

 longer than the inner ones, which are connivent: Ivs. linear, not 

 crisped, 3-6 lines broad. ^y ]y[ 



LACTtfCA (from the old Latin name lac ; referring to 

 the milky juice). Compdsitce. LETTUCE. A well-known 

 genus of hardy annual or perennial herbs, mostly native 

 of the northern hemisphere. More than 200 specific 

 names have been given to the genus, probably half of 

 which are synonyms with but only 8 or 9 known in cult., 

 and these are doubtless forms of but 2 or 3 species. 

 Plants 2-4 or more feet high, with alternate, variously 

 shaped Ivs. and small-panicled heads of yellow, white or 

 blue fls. Only 1 species is to be found in the American 

 trade, though wild plants of other species ar,e often 

 gathered for medicinal purposes or used as a salad. All 

 of the species possess narcotic and sedative properties, 

 the sedative known as lactucarium or lettuce-opium, 

 being obtained principally from the European species, 

 L. virosa. Lettuce has been known and used as a salad 

 from a very remote period. It is said to have served at 

 the tables of Persian kings 400 B.C. See Lettuce. 



sativa, Linn. LETTUCE. An annual plant, not known 

 in the wild state but generally supposed to have origi- 

 nated from L. Scariola, Linn., in Asia. There are 

 many garden varieties assuming an endless variety of 

 forms but which may be divided into 4 quite distinct 

 types. 



Var capitata, Hort. (L. capitata, DC.). COMMON 

 CABBAGE LETTUCE. Lvs. entire or sparingly dentate, 

 broad, rounded, yellowish or brownish green, more or 

 less wrinkled and in some garden varieties much curled, 

 spreading, 6-14 in., usually quite compact. 



Var. intybacea, Hort. (L. intybacea, Jacq. L. quer- 

 clna, Linn.). CUT-LEAVED LETTUCE. Lvs. 6-10 in. long, 

 deeply and irregularly cut on the edges, loosely spreading. 



Var. Komana, Hort. Cos LETTUCE. One to 2 ft. high : 

 Ivs. entire or sparingly dentate, much longer than 

 broad, quite erect, forming a cylindrical or conical- 

 shaped plant. 



Var. angustana, Hort. (L. angustana, Hort.). Lvs. 

 1-2 in. wide, 6-12 in. long, entire, slightly spreading in 

 habit. 



L. Canadensis, Linn. Biennial, 4-9 ft. high : Ivs. entire or 

 nearly so. Wild plants often gathered for salad. i. perennis,, 

 Linn Root perennial, 2-3 ft. high: Ivs. 8-10 in. long, deeply 

 cut: fls large, purple. Native of Eu.-l/. Scariola, Linn. 

 PRICKLY LETTUCE. Annual or biennial, sometimes 6 tt. high: 

 Ivs 1-2 in. wide, 4-6 in. long: fls. yellow, inconspicuous. Int. 

 from Old World, and now a widely distributed weed.

LADRONES. The Ladrone or Mariana Islands (Fig. 

 1222) lie about 1,200 miles east of the Philippines. The 

 seventeen islands contain about 400 square miles. Guam 

 is the southernmost of the islands, and is about as 

 large as all the rest together. It is 600 miles from the
