ODONTOGLOSSUM. 467 



0. Texativum, Bchh. f. — This showy plant is one of recent 

 introduction, and is probably a natural hybrid between 0. 

 nehulosum and 0. maculatum. It has oblong compressed 

 pallid pseudobulbs, ligulate leaves, and tall racemes of large 

 showy distant flowers. The sepals are light brown tinged 

 •with gi-een and margined with white ; the petals are broad, 

 pure white spotted at the base with greenish brown, and the 

 broad semiovate blade of the lip is white with a few spots 

 at the base ; the callus is trifid, j^ellow with a few reddish 

 brown spots. The growth of the plant is intermediate 

 between that of the two supposed parents, ilt was first 

 bloomed by Lord Londesborough under the care of Mr. 

 Denning, the flowers having been produced in August and 

 September. — Mexico. 



0. Yexillarium, Bchh. f. — This magnificent Orchid ranks 

 among the most beautiful of the Odontorjloss'ums, and is at 

 the same time very distinct from its congeners. It has been 

 known for about twenty years, but it is only within the last 

 few years that, after numerous futile eflorts, it has been im- 

 ported in a living state. It now proves to be a most valuable 

 addition to the genus on account of the large size and distinct 

 colour of its flowers, which measure as much as four inches 

 in depth and three inches across. The plant has small 

 narrow oblong compressed pseudobulbs, and light green elliptic- 

 lanceolate acuminate leaves eight to ten inches long and an 

 inch broad ; the slender scapes are produced from the sides 

 of the bulbs, and bear from five to seven flowers each, the 

 sepals and petals being oblong obtuse, of a bright rosy pink, 

 and the large orbicular two-lobed lip of the same colour. 

 There are many varieties of this charming species, some 

 much lighter than others. We find this plant succeeds best 

 in the Cattleya house during the winter months and up to 

 the time of flowering, after which it should be placed in the 

 Odontoglossum house ; it delights in an abundant supply of 

 moisture during the growing period. — New Grenada.
