occurred that the filament thus adhering was flanked by a pair of 
petaloid wings. 
Petals adherent to sepals have been observed by Goeschke *. 
Of greater frequency is the union of stamens of different whorls. 
Inthis way there arise cases which, if they were normal, would con- 
sign such plants to Linneus’s 16th, 17th, and 18th Classes. Out of 
the many cases observed, we only mention the most remarkable :—

There are in this case three bundles, two consisting of two, and 
one of four stamens; the upper row represents the antipetalous 
stamens. 
2. To the inner side of a sepal there was adherent a compound 
body consisting of one antisepalous stamen, one antipetalous 
stamen with a petaloid appendage. In this case consequently 
four elements of four separate whorls were united. 
3. In a tetramerous flower the antisepalous stamens were 
bent inward and united both with one another and with the 
style. The antipetalous stamens, on the other hand, were bent 
outward and quite independent of each other. Two of the latter 
bear small appendages, as last rudiments of the corolla, the 
other two stamens showing nothing behind them. The ovules of 
this peculiar flower were few and abortive, though the small 
ovary looked normal out- and inside. 
4. An antipetalous stamen is adherent to the adjoining anti- 
sepalous stamens (Pl. LVIII. fig. 38) and at the same time to the 
petal, which has expanded into a sort of arched roof over the three 
anthers. On theother side, the five remaining stamens constitute 
a whole, with respect to which two petals behave just in the 
same way. Only the fourth petal has remained free, and occu- 
pies the usual place on the edge of the tube. 
The diagram (Pl. LIX. fig. 39) shows the peculiar relation of 
the organs mentioned. The two bundles were united so as to 
form a single tube beneath. 
At the close of this section wejagain draw attention to 
Pl. LVIII. fig. 21, the drawing of a Scaramouche ; as may be 
seen there, the twelve parts, which usually are free, have grown 
together in four parts; their position opposite to the sepals has 
been referred to above.
