LINDLEY ON FLOERKEA OF WILLDENOW. 3 
the style quits the ovarium, and an exalbuminous embryo 
with plano-convex cotyledons, all which equally exist in 
Floerkea. On the other hand, if we inquire into the differences 
that exist between this plant and the Order to which I have 
suggested that it may be referred, we find that they consist, 
firstly, in the absence of stipules; secondly, in the presence of 
petals; thirdly, in the tube of the calyx not becoming indu- 
rated; and, finally, in those stamens, which are opposite the 
sepals, being the most developed—the reverse of what occurs 
in Sanguisorbee, But in Rosacee, of which many would have 
the latter to be a part, although an Order in which stipules are 
usually highly developed, they are absent in Spiræa, &c.; the 
presence of petals in the rudimentary state in which they exist 
in Floerkea, would rather confirm its affinity with an apetalous 
Order, than its relation to one in which the petals are habitu- 
ally perfect: just as in 4maranthacec, Jllecebree, Euphorbia- 
cece, and the like, where similar appearances occur; the want 
of induration in the tube of the calyx is probably due to the 
absorption of the disk, in this genus, at a very early period, 
and may be regarded as a specific character rather than as 
one affecting its ordinal position; and, finally, the presence 
of petals may be supposed to explain the cause of those 
stamens, which are alternate with the sepals, being the 
least, instead of the most, developed, as is usual in apetalous 
Sanguisorbez.
