ODONTOGLOSSUM. 443 



a hundred plants of 0. ijrande, forming a really beautiful dis- 

 play. — Guatemala. 



0. Hallii, Lindley. — A very charming and beautiful species 

 belonging to the 0. luteo-purpurcum. section, but having 

 flowers far superior and more beautiful than those of any 

 variety of that species. The pseudobulbs are ovate acuminate 

 ancipitous, about three inches high ; the leaves ensiform, 

 upwards of a foot long, and two inches broad, light green, 

 and the scape many-flowered, produced from the base of the 

 bulbs. The flowers measure about four inches across, the 

 sepals and petals being ovate-lanceolate acuminate, bufi" yellow, 

 heavily blotched and the petals barred near the base with 

 purplish brown ; and the large oblong acuminate lip is white 

 with a rich yellow throat streaked with orange and white, the 

 surface blotched with purplish brown, the margin white and 

 beautifully fringed. There is a large multipartite crest at the 

 base of the lip. This plant is sometimes called by the varietal 

 name leucoglossum to distinguish it from the next, but as it 

 represents the type of the species which had a white lip, this 

 name is quite supererogatory.— P<?rw ; New Grenada, eleva-

 distinct variety having large flowers, with broad sepals and 

 petals, the colour of which is a bright yellow beavily blotched 

 and spotted with chestnut brown ; the lip is large and broad, 

 bright yellow spotted with reddish brown. This variety 

 forms an efiective companion for the white-lipped O. Hallii.. 

 It flowers during the spring and summer months. — Peru. 



0. hastilabium, Lindleij. — A handsome pleasing and fra- 

 grant Orchid, which produces its flowers in June, July, and 

 August, their colours being purple, green, and white. It con- 

 tinues blooming for two months if kept in a cool house. The 

 pseudobulbs are oblong compressed, ribbed, bearing a pair 

 of linear-oblong obtuse leaves, and from the axil of an 

 accessory leaf at its base a panicle of fragrant flowers, some 

 three inches in diameter, with the linear lanceolate acuminate 

 undulated sepals and petals pale green barred transversely 

 with thin purple lines, and the broadly hastate lip having the 

 basal part purple, triangular, with two acute side lobes, and
