rated by a long internode from the other leaves, which 
remain closely packed ; and further, suppose an evident 
thickening of the upper portion of the lengthened 
internode, and there will be not only a single bulb,

bearing with the leaves of the present year all the 
remnants of the leaves of the two preceding years, but 
two bulbs placed one above another, on the same axis, 
separated by the length of the internode.” 
The formation of bulbs in the axils of the leaves, as 
happens occasionally in tulips, is further alluded to 
under the head of hypertrophy. 
Displacements affecting the inflorescence——T'hese are, for 
the most part, dependent on hypertrophy, elongation, 
atrophy, spiral torsion, &c., but there are a few in- 
stances of a different nature, which may here be alluded 
to as not being coincident with any of the phenomena 
just mentioned. Sometimes these deviations from the 
ordinary position have the more interest as affecting
