Mr. Brown then proceeds to shew that in families, the 
division of whose flower is quinary, the usual relation which 
the parts of the flower bear to the bractea, or spike, is 
that the 5th segment of the calyx is posterior or superior, 
and the 5th petal anterior or inferior. This also is the 
relation which is borne to the axis of inflorescence by the 
flowers of Rosaceae. But in Leguminosae the relation is 
different; the fifth segment of the calyx being anterior or 
inferior, and the 5th petal superior or posterior. In Legu¬ 
minosae, the pistillum is also within the 5th anterior segment 
of the calyx; in Rosaceae, it is within the 5th anterior 
petal. “ But in those Rosaceae in which the pistillum is 
solitary, and placed within the anterior petal, its relation 
to the axis of the spike is the same as that of Leguminosae, 
in which it is within the anterior division of the calyx. 
Andin all families, whether dicotyledonous or monocotyledonous, 
this I believe is uniformly the position of the simple, solitary 
pistillum, with regard to the spike or bractea .”
