ON THE GENUS BENJAMINIA. 567 
the petiole, in the hexamerous flowers, the very elongated free 
position of the tube of the calyx, which, moreover, has six conspic- 
uous scales in the inside near the base, and in the very elongated 
cylindrical tube of the corolla, which, as well as the calyx, is 
6-toothed rather than 6-lobed at the limb. 
Notwithstanding the somewhat decayed state of the flowers, 
the above characters may be relied upon ; and should future 
observations discover marks sufficient to constitute of our present 
plant a new genus, I cannot but wish it should have the name of 
its discoverer, Seemannia.

Note on the Genus Bunsamrnta, Mart. referred by Lupw. BENJA- 
MIN to the family of UrR1icULARIEE; by G. Benruam, Esq. 
The examination and determination of Utricularia, from dried 
Specimens, is a matter of peculiar difficulty on account of the ex- 
treme tenuity and delicacy of the flowers.. It is, therefore, highly 
satisfactory to see it taken up by a young botanist who has evi- 
dently bestowed great pains in the detailed examination of those 
species of which he had specimens at his command, and the result 
has already been a monograph of the Brasilian species in Endlicher 
and Martius’ Flora Brasiliensis, a sketch of the order and descrip- 
tion of many new species in the twentieth volume of the Linnea, 
and an enumeration of tropical American species in the same 
volume of that periodical. He has, however, added a genus to 
the order (to which he had at first given the name of Quinguelobus, ` 
but which Martius requested, out of compliment to his exertions, 
permission to publish under the name of Benjaminia), which struck 
me at once as anomalous, from its opposite inflorescence, and other 
characters ; and on looking into the species, I was surprised to
