distributed. As distinguished from its nearest congener, Angrcecum 

 Ellisii, it is a mucli smaller plant with shorter leaves and somewhat 

 smaller flowers with a much shorter spur. It flowers in IVlarch 

 and April, 



A. bilobum. 



Stem 3 — 5 inches high, as thick as au ordinary writing pencil. 



Leaves obovate-oblong, 4 — 5 inches long, unequally bi-lobed at the apex. 



Eacemes drooping, as long again as the leaves, 7 — 10 flowered. Flowers 



white, about an inch in diameter, on reddish brown pedicels with a 



small acute bract at their base ; sepals, petals and lip nearly uniform, 



lanceolate, acuminate, the petals a little narrower and the lip a little 



broader than the sepals ; spur slender, longer than the pedicel and 



ovary, pale orange-red. Column short, sub-triquetral.

 Alb. IV. t. 162. 



First discovered by Mr. Bowdich at Cape Coast Castle, on the 



west coast of Africa, some time prior to 1840, in which year it 



flowered in Messrs. Loddiges' nursery at Hackney. Four years later 



it was introduced to the Royal Gardens at Kew from Sierra Leone, 



whence it has been since occasionally imported with other orchids. 



The variety Kirlcii was sent to the late Mr. B. S. WiUiams, from 



Zanzibar, by Sir John Kirk in 1881. According to the late 



Professor Reichenbach it had been previously sent by the German 



botanical traveller Hildebrandt from east Africa to the Botanic 



Garden at Hamburgh, where it flowered in 1875. The presence 



of this species on the two opposite coasts of the African continent, 



separated by an interval of upwards of 3,000 miles, is a remarkable 



fact in its geographical distribution. 



A. caudatuni. 



Stem as thick as the little finger, 8 — 12 inches liigli in plants 

 observed, leafy from the base and emitting cord-like roots 2 — 3 feet 

 long, whose growing points have a glaucous Inie unlike any other 

 cultivated Angraecum. Leaves crowded, broadly strap-shaped, 12 — 15 

 inches long and IJ- inch broad, recurved, closely imbricating at base, 

 unequally bi-lubed at apex. Peduncles spreading, or slightly depressed,
