LIST OF COOL ORCHIDS. 117 



pans or on flat blocks suspended near the light. One or two 

 species are well worth growing for cut flowers, as the old 0. 

 flexuosum and 0. obrysatum. 0. cucullatum, or at least one 

 form of it, is found at from 12,000 to 14,000 feet elevation, 

 and from this extreme altitude we find them on the mountain 

 ranges lo^/rer and lower until we come through the temperate 

 .zone, and find some species luxuriating only in the hot 

 tropical valleys and lowlands. Still we have sufficient cool 

 species to furnish us with cut flowers all the year round. 



0. cemulum (New Granada). Inhabits the highlands at a 

 great elevation, and is a vigorous-growing cool species. It is a 

 worthy rival to the splendid 0. macranthum, and, like that 

 species, bears very large flowers. The dorsal sepal is nearly 

 renif orm in shape, and of a warm cinnamon colour ; the lateral 

 sepals are longer, and of a yellowish-brown or cinnamon colour, 

 the petals are very bright cinnamon, all the segments being 

 nicely crisped or wavy ; the lip is marked with purple violet, and 

 is yellow at its base, with reddish-brown streaks. 



0. andigenum. This is a choice kind belonging to the 

 O. cucullatum type, having yellow flowers densely covered with 

 small purple dots ; the column is purple, and the crest of the 

 lip of a deep golden yellow ; flower-spike erect, from five to 

 seven-flowered. The plant in habit somewhat resembles the 

 rtypical species just quoted. It is a native of New Granada, 

 Ecuador. 



0. amictum. See 0. sarcodes. 



0. aurosum. This is another species, producing an abundant 

 .-supply of golden flowers on an erect spike, branched at the top 

 <or near its apex only; flowers individually about one to one 

 -and a hal inch across, golden yellow, spotted with warm 

 -brown. Flowers in autumn, lasting from three to five 

 weeks. 



<0- larlatum. A very free-flowering species, the pseudo-
