LABTBINTHS or mazes are still kept up in some Old 

 World gardens as relics of the past. They were popu- 

 lar in the sixteenth and seventeenth centuries. Fig. 

 1220 is the plan of an English Labyrinth of two centu- 

 ries ago. It would be vandalism to destroy so fine an 

 example of a style of gardening no longer fashionable, 

 but folly to copy it in a modern garden. Mazes are 

 made of clipped evergreens of various kinds. 



LACiENA (one of the names of Helen, which Lindley 

 states may be applied to this plant on account of its 

 beauty, a compliment which the plant does not at all 

 merit; but he adds it may also be derived from Lakis, a 

 cleft, alluding to the divisions of the lip, but this deri- 

 vation is impossible). OrchidAcew. A little-known ge- 

 nus containing only 2 species inhabiting Central Amer. 

 Pseudobulbs rather long, ovoid, smooth at first: lvs. 

 large, elliptic-pointed and contracted into a petiole, pli- 

 cate venose: raceme pendent from the base of the pseu- 

 dobulbs, loose, bearing up to 10 medium-sized fls.: 

 sepals and petals nearly equal, elliptical, half-spread- 

 ing; lahellum equaling the petals, articulated to the base 

 of the cohiiiin, clawed, with the lateral lobes incurved, 

 terminal larger, spreading and narrowed at the base to 

 a broad claw : column rather lung, winged, hooded at the 

 top; pollinia 2 on a simple stipe. 



The plants should be grown in baskets or on blocks 

 of wood like Stanhopeas : if potted the racemes are likely 

 to bury themselves in the soil. At the end of October 

 water should be almost entirely withheld for a few 

 weeks. The flower-stalks appear in spring. 



bicolor, Lindl. Eacemes drooping, about 18 in. long, 

 bearing 9 or 10 fls. The fls. are greenish yellow, covered 

 externally with short hairs ; petals with 3 purple streaks ; 

 labellum hairy, spotted with purple. Discovered about 

 1843 in Guatemala, at an elevation of 7,000 ft. B. R. 30 :50. 

 — Var. glabr&ta,Lem. Fls. everywhere nearly glabrous, 

 creamy white. Not in the American trade. I.H. 1:33. 



spectibllis, Reiclib. f. Fls. about 1 in. in diam., whit- 

 ish, suffused with pink and speckled with purple; 

 sepals concave orbicular ; petals smaller connivent. 

 B.M. 6516. -Far more handsome than the former, but 

 not advertised in America.
