68 AGANISIA. 



The horticultural history of Colax jugosus is of the briefest 

 description. It was first imported from Brazil by Messrs. Loddiges 

 in 1840, and has doubtless been in cultivation ever since, although 

 it was very rare during the twenty-five years immediately following 

 its introduction. Its precise habitat does not appear to have been 

 recoi'ded, although it is evidently known to the orchid collectors 

 of Rio de Janeiro. 



AGANISIA. 



Lindl. in Bot. Reg. 1S39. misc. No. 65. Bentli. et Hook. Gen. Plant. III. p. 544. 



A genus of about ten species dispersed over tropical America, in 

 which Mr. Bentham has included Warrea ci/anea (Lindl.) and 

 Reichenbach's Koellensteinia. The genus is singular in the sub-tribe 

 in which it is placed, in the base of the column not being produced 

 into a foot. The following are the best known species in cultivation, 



Agauisia cyanea. 



Leaves lanceolate, acuminate, plicate, 7 — 10 inches long. Peduncles 



erect, longer than the leaves, racemed and few - flowered along the 



apical half. Flowers about an inch in diameter ; sepals and petals 



broadly oval-oblong, the sepals white with a faint tinge of blue, the 



petals veined and margined with indigo-blue ; tlie dorsal sepal concave, 



the lateral two longer and narrower and the petals smaller than the 



dorsal sepal ; lip fan-shaped, apiculate, undulate, white at the base, 



the marginal area blue ; crest with 1 — 5 slightly divergent lamellae. 



Column clavate, bent.

An orchid now but rarely seen, remarkable for the pure blue of 



its labellum. It was originally imported by Messrs. Loddiges from 



Colombia, but no locality is recorded. The plant described above 



is in the collection of Sir Trevor Lawrence, Bart., at Burford Lodge, 



Dorking. 



A. ionoptera. 



Pseudo-bulbs clustered, ovoid, about the size of a filbert, mono- 

 diphyllous. Leaves narrowly lanceolate, sub-carminate, 4 — 7 or more 

 inches long. Scapes purplish, about a foot long, racemed above tlie 

 middle, 7 — 10 or more flowered ; cauline bracts distant, lanceolate, 

 acute, sheathing ; floral bracts similar, shorter than the ovaries.
