REPORT ON BOTANY, MDCCCXLI : 
same state as it had in the testa (fig. 7), proving that it does 
not experience any material change by germination, nor is it 
converted from a genuine seed into a bulbillus. It was im- 
possible even for M. Schmidt, who certainly possesses great 
ability in making fine incisions, to do this with the seed when 
situated within the testa, but it was easily done in the seed 
which had just begun to germinate. A bundle of spiroids was 
likewise found to be here situated in the centre, and every 
thing else was filled up with cellular tissue (parenchyma). The 
cells in the circumference contained chlorophyll; the cells 
towards the centre, however, dark granules — phakocysts, as 
Decaisne terms them (fig. 10). A fine longitudinal incision 
was made, after the embryo had advanced so far as to exhibit 
two perfectly developed leaves (fig. 9). It exhibited little 
change from the former ; the bundle of spiroids had enlarged, 
and separate vessels entered into the leaves. The number of 
the chlorophyll cells had rather decreased than increased, and 
the phakocyst had dissolved itself into small granules (fig. 11). 
Instead of a large root, as Angrcecum exhibited, only fine 
root-leaves, which surrounded the nucleus, were found. On 
making a longitudinal incision through a bulbillus of Lilium 
hulhiferum, a bundle of spiroids will likewise be found in the 
centre of the cellular tissue, from which the separate vessels 
are given olf upwards into the layers of the bulbillus (fig. 11). 
The only difl’erence is found in the fact, that the seed of these 
Orchidece is quite naked, whilst the bulbillus is enveloped in 
leaves, as may be seen in the transverse section (fig. 10). 
Three roots are always attached to the Lilium hulhiferwn 
(fig. 12), which usually have a bundle of spiroids in the centre, 
without pith; spiral fibrous cells, however, are seen in the 
circumference, similar to those in the aerial roots of the 
Orchidece.
