We received this plant at Kew, from Mr. Makoy of Liege, 

 under the name here adopted, and though some discrepancies 

 exist between our specimen and the figure of Lambert above 

 quoted, yet they are too trifling to lead me to suppose the species 

 otherwise than the same. In Mr. Lambert's representation the 

 leaves are narrower, the flowers rather smaller, and the segments 

 of the calyx and corolla are too short ; probably occasioned by 

 being drawn from an imperfect specimen in the Herbarium of 

 Aubfet Lambert gives Guiana as the native country of the spe- 

 cies ; while De CandoUe, on the authority of Richard, says it is in- 

 digenous to St. Domingo. Be that as it may, it constitutes a very 

 pretty shrub, flowering freely and copiously, and the blossoms 

 are fragrant and remarkable not only for their great length but 

 for their change of colour, at first pure white, gradually becoming 

 red. Exostemma is a genus separated from dnehom, chiefly on 

 account of its exserted stamens, whence the name U», without,
