Nefiary (lahellum oF Swart z) fpathular-fhaped, veined, tliree- 

 lobed, revolute at the point, the lower part embracing and 

 united with the fide of the column. The neclary is internally 

 continued very nearly to the bafe of the germen, where it 

 aclually terminates in a double fpur, though perfectly concealed 

 within the covering of the germen j fo that a tranfverfe feclion 

 of the germen fhews two cavities, the one containing the young 

 feeds, inferted into three parietal receptacles, the other filled in 

 part with a honied juice. A longitudinal feclion of the flower 

 down to the bafe of the germen fiiows the cavity of the neclary 

 in front of that of the true feed-veffel contracted towards the 

 bottom, where it is fomewhat hairy; and immediately below 

 this contracted part it divides, and terminates in a double fpur. 

 The ilyle terminates in a point crowned with a moveable purple 

 hood, into which, in an advanced ftate of the flower, the united 

 pedicles of the pollen mailes are inferted. 



The flower is fragrant, fmelling fomething like lemon, with 

 a flight mixture of mufk. 



This very curious and rare plant of the Orchis tribe, native 

 of the Ifland of Trinidad, was fent by Dr. Anderson to 

 Mr. Evans, of Stepney, feven or eight years ago, under the 

 name of ARETHUSA/>icZt?. It flowered the year after, but in 

 fo defective a manner that it produced no fcape, the flowers 

 growing intermixed with the leaves in a Angular manner, which 

 induced Dr. Smith to give it the name oiacaulis. 



Our drawing and defcription were taken from a plant com- 

 municated by Mr. Kent, of Clapton, in April laft, which was 

 originally an offset from Mr. Evans's, and is therefore de- 

 cidedly the fame as the acaulis of the Exotic Botany. 



We had a drawing of this fpecics taken, in the ipring of the 

 year 1812, at Mefirs. Lee and Kennedy's Nurfery, but not 

 having had an opportunity of feeing the plant, we were not at 

 that time aware of its being the Neotti a acaulis of Dr. Smith. 



Requires to be kept in the bark flove. Propagated by offsets. 

 Flowers in April and May.
