without a backing petal has, just up to the anthers, grown 
together with one of the adjoining antisepalous stamens.

In n°. 11 (Z. carinata) a petaloid wing in connection with 
one of the sepals is seen on the surface of the ovary. 
In n°. 13 two sepals are narrower than the others and three 
of the ovary cells smaller. Only 3 stigmas. 
In n°. 14 two bracts, a wide and a narrow one, opposite 
one another. 
N°. 15 has five stigmas. 
N°. 16 has six stigmas.

Two stamens (antisepalous and antipetalous) coalesced. As is 
well known, the six filaments are at the base united by a 
funnelshaped cup. Between the two coalesced stamens the 
portion of the cup is reduced projecting outward as a fold.

1°, An additional petaloid leaf just under the point of divi- 
sion of the perianth. 
2°. A sepal has coalesced along its whole length with one 
of the neighbouring petals; a fold projecting outwards proves 
that their coalescence has not entirely impeded their growth. 
Also the filaments, not the anthers, of the parts in question, 
have grown together. 
3°. Two sepals and the petal between them have quite coa- 
lesced to one whole; opposite to this there are #vo stamens 
with filaments that have coalesced, the third stamen having 
been suppressed.
