in the pedicellate character of their neutral florets. 7) 3 
are not axillary in either of them. The branches are axillary 
of which several sometimes originate from the same axil in the 
R. corrugata. Each spike, when fully evolved, is not only 
pedicellate, but the pedicel, or peduncle, is connected with a 
culm containing one, two, or more joints.* The culm is not 
compressed, nor the leaves long in the R. ciliata, as stated by 
r. Nuttall, who appears to have confounded the two species 
in these, and some other instances. The joints of the rachis 
in both are fragile, the joints of the culm in neither. 
Another species noticed by Michaux, and included in all our 
books as the R. dimidiata, L. has long been familiar to the south- 
ern botanists. Whether this be the dimidiata found also on 
the sandy shores of India, or the compressa of the same country 
as suggested by Mr. Elliott, or a species distinct from either, 
I am not prepared to determine. ButI have collected this 
plant in the Bermudian Isles, at Rio de Janeiro, and Bahia, on 
the Brazilian coast, and lastly on the island of Flores, near one 
hundred miles from the mouth of the Rio de la Plata, as well 
as on the main in the Banda Oriental.

Miscellaneous Remarks, by Dr. ——— W. Wituiams, of

Sir, 
Any thing which has a tendency to elicit facts with regard 
to the climate of a country must be interesting. I believe 
that observations upon the the time of the germination, foliation, 
florification, and fructification of plants, afford.a much more 
correct criterion respecting climate than thermometrical, or 
other meteorological journals. They should be made at the 
Mr, Nuttall was probably deceived from having examined the sptkes before 
they were fully evolved.
