IN FUCHSIA GLOBOSA. 399 
$1. Additional Parts in the Flower of Fuchsia. 
Fuchsia has an inferior ovary, a tolerably long calyx-tube, four 
sepals, four petals, eight stamens arranged in two rows of four 
each, and on the top of the four-celled ovary a honey-gland 
and a style with a four-lobed stizma. It shou!d further be 
noted that the antipetalous stamens are external to the anti- 
sepalous ones, an arrangement for which the term “ obdiploste- 
monous" is used. In $2 the question will be discussed whether 
these outer stamens are to be regarded as intercalated elements, 
or as outgrowths from the petals. 
Besides the parts named, there often appear additional parts 
which seem to grow out from the edge of the calyx-tube. They 
have the shape either of little threads, straight or curved, or 
take the form of petals. Fig. 1 shows in a the shape of a thread, 
inb that of a petal, and in e a combination of the two. In 
double Fuchsias the number of additional parts as compared 
with the four ordinary ones may be very large; in them also 
some thread-like parts appear between the others, and even an 
additional stamen sometimes may be seen. Although the addi- 
tional petals closely resemble the ordinary ones, yet many of 
them are much narrower, others attracting attention by incisions, 
and appearing therefore lobed. 
In the case of a great many additional petals being together 
in one flower, owing to their cramped and crowded position, they 
are bent to and fro, twisted or folded. For reasons, afterwards 
to be explained, special attention is drawn to a peculiar out- 
growth from the inner side of some of the additional petals; 
it essentially consists of a thickening of the midrib, and will be 
described together with the petals in $2. 
The augmentation of the petals has no influence whatever on 
the two whorls of stamens, parts which in many other plants, 
for instance roses, auemones, &e., are easily affected under the 
same circumstances. However numerous the additional petals 
may be, the stamens are always 8 in number, and the single parts 
in most cases appear unaltered. It is strange, therefore, that 
Masters considers petalody of the stamens to be the chief cause 
of doubling in Fuchsia *.
