THE ORCHID WORLD. 



[September, 1916. 



Odontoglossum Hallii. 



ODONTOGLOSSUM HALLII. 



THIS fine old species, a native of 

 Ecuador, was discovered by Col. 

 Hall, in 1837, in the Andean valley of 

 Lloa, in the Quito district, at 8,000 feet 

 elevation. A few years afterwards Hartweg 

 gathered it on the western slopes of Pichincha, 

 and later, Jameson in other localities on the 

 Andes; but it was not until 1864 — 5 that it 

 became known in European collections, 

 through the importations of Messrs. Low and 

 Co., M. Linden, Messrs. Backhouse, and 

 Messrs. J. Veitch and Sons. 



The flowering season is March — May, but 

 when out of flower the plant may be distin- 

 guished by its long, thin, and narrow bulbs 

 with parallel close-set longitudinal furrows. 

 The many-flowered spikes attain a length of 

 2 — 4 feet. The individual flowers, which are 

 slightly fragrant, have the sepals tipped with 

 clear yellow, the remaining portion bearing 

 large, nearly confluent, dark chocolate-red 

 blotches on a yellow ground ; the petals are 

 more heavily tipped with yellow ; the spots on 



the basal area are smaller, more numerous, 

 and arranged in slightly irregular lines. The 

 hp IS yellow, sometimes white, and more or 

 less spotted with red. The well-developed 

 crest on the labellum is bright yellow. 



Cattleya Naidia. —Although this hybrid 

 has been known for less than a year, it has 

 proved to be one of the brightest of the 

 Cattleyas, the clear golden-yellow and rich 

 crimson colours being remarkably attractive. 

 The parents are iridescens (bicolor x 

 Eldorado) and Hardyana (Warscewiczii x 

 aurea), from which it will be seen where the 

 yellow of the sepals and petals is derived and 

 from whence comes the exceedingly fine lip, 

 for three species concerned in the parentage 

 are noted for the rich coloration of their 

 labellums. Messrs. Hassall and Co., who 

 raised C. iridescens in iQOg, have produced 

 in C. Naidia not only a beautiful flower, but 

 a plant whose constitution enables it to be 

 cultivated successfully by every amateur.
