portion of, 4 b portions of the outer layer of which the 
calyx is a direct continuation ; inner layer d, a nucleus, d 
funicle, e embryonary sac, f embryo. 
9. Some more advanced, the same letters have the same 
references ; f, a detached embryo (not enlarged enough) 
young to shew the nature of its pedicel. 
6. Very young ovary laid open a a outer layer, 5 inner 
ditto, closely investing the ovula c. 
6a. Ovule, c detached.

end. 
9. Young fruit, a outer layer, 5 inner do., c nucleary do.

Those leaves are abortive that are on the opposite side 
of the stem to the inflorescence, it follows hence that as the 
inflorescence is unilateral one side of the stem throughout its 
flower-bearing portion, will produce leaves, the other flowers ; 
of the leaves, one axil is empty ; the other bears alternately 
à flower bud. 
: The inflorescence although tending to the umbellate form, 
"t true compound raceme, its form is curious, in as much as 
Y presents none of that irregularity so prevalent in cymes, 
to which class it obviously belongs. We may therefore meet 
with one flowered species, in which case no bractes will be 
eloped, or we may meet with a one flowered species, with 
; but these empty.
