The discoverer of this nice Catasetum was Sir Robert Schom- 
burgk, who found it in 1836, on the Ela Palm (Mauritia flexuosa), 
at the place where the spadix generally developes itself. He 
found it in British Guyana, in the Cannuni Creek, a tributary of 
the river Demerara; also very frequently at the low and marshy 
ground of the rivers Wironi and Wicri, tributaries of the river 
Berbice: there the leaves were sometimes six to eight feet long. 
The Macusi Indians call it Masamu; the Waraus have given it 
the name of Okityon. The flowers were observed of a lake- 
colour. Messrs. Loddiges obtained a supply of specimens. The 
plant was also sent from Demerara by Mr. Henry Gloster, 
Attorney-General of the Colony. It flowered in September, 
1839, with Mr. Brocklehurst, of the Fence, Macclesfield, and 
with Mr. Valentine Morris, of the Retreat, Battersea, in October 
and November, 1839. It is well known that the plant obtained 
by growers and gardeners the nickname “the Catasetum that 
never flowers.” We had never seen any other vestige of it than 
the dried inflorescence of Dr. Lindley, who was unable to give 
us a single flower, since all his were glued on stiff paper. We 
felt most agreeably surprised when, at the end of September, 
1868, we found a strong healthy specimen at Hillfield House, in 
the Saundersian collection. In a few months it produced the
