without a backing petal has, just up to the anthers, grown 

 together with one of the adjoining antisepalous stamens. 

 E. The formula in Jive specimens is: 



b^ r ., ot4 + 4 0(1") 



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°. lo 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 

 fminelshaped 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 two stamens 

 with filaments that have coalesced, the third stamen having 

 been suppressed.
