Whether the Erianthus saccharotdes of Michaux is the same 
or not must remain doubtful until his type is seen. 
As to the separation of Panicum into a number of genera, 
this of course must be a matter of individual opinion. If it 
can be divided into groups, why not call these groups genera? 
At all events consistency should be used in the treatment of 
the subject. If it is thought best to make one vast genus out 
of all these related groups, it would seem better not to draw 
any arbitrary lines. Why should not Paspalum be included 
also, as it approaches Eupanicum as closely as does Synthe- 
tisma? How large is to be this aggregation? Cannot Erio- 
chloa, Anthaenantia, Oplismenus, Ixophorus, Pennisetum, 
etc., come in with equal propriety? 
Nothing new is added by your contributor to the argument 
in reference to Panicum latifolium L. As the matter has 
been referred to, it may be well to call attention to the work 
of Doell, for whose judgment your correspondent seems to 
have respect, as evidenced by his remarks in relation to Syn- 
therisma. Doell? has applied the Linnaean name latifolium 
to the tropical plant, and cites P. divaricatum L. as a syno- 
nym. Among the synonymy, and heading the list, will 
be found Bambosulus latifolius Sloane, Voy. pl.-71. fig: 3: 
As Linnaeus refers to this same figure’ it is not difficult to 
understand what he had in mind and whence he derived the 
name latifolium. If Linnaeus had in his possession, at the 
time of the publication of his first edition of the species Plan- 
tarum, the plant which Munro says is attached to the sheet 
bearing the tropical plant, would he not have referred to it in 
Ye way? Linnaeus simply says: ‘‘Habitat in America.” Un- 
‘t P. clandestinum, published on the same page, he distinctly 
States that he had that plant from Kalm. _Is it not clear that 
4g received from Kalm, after the publication of his first edi- 
a the plant which Munro says was ticketed, ‘‘From Kalm, 
t orth America?” At Kew the name has been applied to the 
ical plant, as shown by a number of specimens in the
