end is clasped by the glaud, which projects a little beyond it. 

 The stigma is semioval and rather deeply sunk. 



The affinity of this plant is with A. apiculutum, Lindl., a native 

 of Sierra Leone.

All were introduced into cultivation from Madagascar, and 

 appear to be extinct again in England. I have seen no speci- 

 men, wild or cultivated, in the herbaria of the British Museum or 

 Kew.

This fine plant was introduced into cultivation by Rev. W. Ellis, 

 whose name it bears. 



It is characterized by its completely reflexed petals and sepals, 

 which give it the appearance of a hovering bird. It has large 

 dark-green leaves, 10 inches in length by 2 across, broadly ligulate 

 and unequally bilobed. The flower-spikes in cultivation attain a 

 length of 2 feet; they are somewhat nodding, and bear from 

 18 to 24 flowers, very fragrant, from pure white to yellowish 

 white ; the long gracefully curved spur, (5 inches or less in length, 

 and the ovary being of an ochreous-cinnamon colour.

I only know this species from Thouars's figure, unless the plant 

 collected by Deans Cowan above mentioned belongs to it. 

 This closely resembles A. filicornu in most respects, but the lip, 

 instead of being pandurate and rather acute, is oblong-elliptical 

 and blunt, and the spur is only 2 inches long. The stem is 

 ftexuous, about 6 inches high ; the leaves linear, spreading, blunt,
