A bud, 3 eM. across, still preserves the same aspect, but a 
vertical section through it shows quite well formed leaves 
(bracts and perigoneal lobes) in its interior, and in its centre 
we find a small, rentlike cavity, of infinitesimal height, 4 mM. 
long and 0,5 mM. broad, below which tue disc of the column 
is discernible as a small, slightly convex plate. 
Having reached a diameter of 4 cM. the superficial cover of 
the bud, provided by the vine root, begins to open on its top. 
A small perforation forms, through which a corresponding part 
of the real bud shows, covered with its sparkling, brown bracts. 
During the further development this opening grows larger and 
after a while the bud pushes out through it, and in a certain 
stage we find it fitted in its cupula just as an acorn in its cup. 
Now the development of the bud goes on at a quicker rate. 
The bud takes the form of a slightly flattened ball, and the 
cupula upon which it rests, gets broader and flatter, soon assu- 
ming the form of a saucer. 
Of a female bud, 7 cM. across, I possess the ‘cllevded notes: 
There are 28 or 29 bracteae. The superficial ones are dry and 
scaly, brown and very small; the medial ones are more fleshy, 
white at their base and brown. at the top, whereas the 10 must 
profoundly seated are very thin, soft and of a beautiful rosy 
colour. The perigoneal lobes are clearly visible but form one 
substantial mass, having the form of a strongly convex watch- 
glass. Its underside shows the diaphragm, upon which the white 
spots are already distinctly marked as tiny, smooth, brilliant 
prominences, looking like certain colonies of bacteria upon gela- 
tine plates. Their number is about 110. Through the central 
opening of the diaphragm the underside of the innermost lobes 
of the perigony appears, covered with small spots, representing 
the warts. Ramenta are not yet visible. 
An other female bud of the same size (7 cM.) possessed 5 
small, dry scales, derived from the margin of the cupula, and 
24 bracts, originating from the base of the perigoneal tube. On 
a section through the perigoneal body the fine outlinings of 
the individual lobes are clearly discernible. The disc carries 37
