 "The varieties are connected by intermediate stages. 

 Several hybrids between L. pendula and the varieties 

 of i. 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 i. peiulitla."

 segments tipped green. B.M. 1372. 



9. uniJdlia, 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 Dipeadi filamentosum, which is distin- 

 guished from the species of Laeheualia by having 3-6 lvs., 

 which are linear: raceme very lax: tis, briglit green. Cape. 

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

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

 pressed, while in L.achenalia they are obovoid or globose. D. 

 viride is distingaished from all other species in its genus by 

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



longer than the inner ones, whicli 



crisped, 3-6 lines broad. 



trade, though wild plants of other species are 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. I'irosa. 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. Letti'ce. An annual plant, not known 

 in the wild state but generally supposed to have origi- 

 nated from L. Scariula, 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 capitita, Hort. (L. i-npltiltn. DC). Common 

 Cabbage Lettuce. Ly~^. .iitin- ..r sparingly dentate, 

 broad, rounded, yellowish ..r lir.iwnish green, more or 

 less wrinkled and insom.' gar.l.ii vari.ties much curled, 

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



Var. intybicea, Hort. (L. intybUcea, Jacq. L. quer- 

 cl»a,Linn.). Cut-leaved Lettuce. Lvs. G-10 in. long, 

 deeply and irregularly cut on the edges , loosely spreading. 



Var. Koma.na, Hort. Cos Lettuce. One to 2 ft. high : 

 lvs. entire or sparingly dentate, much longer than 

 broad, quite erect, forming a cylindrical or conical- 

 shaped plant. 



Var. an^stina, Hort. [L. angnstdna, Hort.). Lvs. 

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

 seventeen islands contain about 400 square miles. Guam
