Cuphea Melvilla [...]
Melvilla speciosa. Anderson in journal of Arts and Sciences. [...]
This fine plant is a native of swamps in Guiana, and in Fort Zeland, Island of Essequebo, whence it was introduced to the Botanic Garden, St. Vincent's, by the late Dr. Anderson, who considered it a particular genus, and named it after his friend General Melville, at that time commander of the forces upon the island. To that officer, and to Dr. Young, who was Staff-Surgeon at the time, the late garden at St. Vincent's owed its origin.
We do not perceive any character, beyond the absence of petals, by which
Melvilla can be distinguished from
Cuphea; to one species of which,
C. Jorullensis of Kunth, which is also apetalous, it seems to be nearly related.
For the introduction of this plant to our gardens the public is indebted to the exsertions of Mr. Jams M'Crae, lately employed upon the establishment of the St. Vincent's garden, and now upon a mission to the Sandwich Islands, in the service of the Horticultural Society. Our drawing was made in the stove of the Comtesse de Vandes. We have examined authentic specimens from Dr. Anderson, in the Herbarium of Mr. Lambert. J.L." [protologue].
