tion evidently depends. Later on in the year the old bulb disappears, the 
horizontal rhizome thus becoming free. Then the rhizome dies in the part 
which does not produce rootlets; and at the same time a new rhizome arises 
from the base of the bulb of the year, to form in its turn at its extremity 
another bulb to yield the flower-stem of the year following. There are pro¬ 
duced, then, in these Lilies a succession of subterranean bulb-bearing branches, 
or a series of successive generations, each of which has an annual bulb for its 
fundamental basis.’ 
“ In parting from this squamose type of structure, I wish to point out that 
there are three different kinds of ‘ rhizome ’ in different species, developed in 
connection with it, all of which are spoken of in books under the general term 
‘ rhizome,’ but which are not homologous, namely :—1st, the produced oblique 
central axis of the Californian Lilies; 2nd, the lower part of the horizontal 
branch, originating from a bud developed in the axis of a leaf-scale, which 
branch at its extremity bears a new bulb, as in Lilium canadense; 3rd, the 
lowest part of the flower-bearing stem above the bulb when it creeps below the 
surface of the soil, as in L. Leichtlinii.” 
To these remarks of Mr. Baker’s, we may add that Lilium Wilsoni^ figured in 
our volume for 1868, p. 121, and referred by him and others to L. Thunhergianum^ 
as a variety, has a mode of development unlike what is met with in that or in 
any other known cultivated species. This plant produces from the outer scales 
of the matured bulbs a kind of underground runner, which terminates in a flower- 
stem ; but its chief peculiarity is that it bears, at intervals of two or three inches 
as it progresses, young equal-sized bulbs, which afford an excellent means for the 
rapid increase of the plant. The bulbs of the original plant propagated themselves 
in this way, and seedlings from it, which have reached the flowering stage, and 
which may consequently be safely identified, possess, in a full degree, this re¬ 
markable habit, which, as we learn from Mr. Wilson, is not found in any other 
species, the horizontal portion of the flowering-stem of L. Leichtlinii not being 
(at least normally) bulbiferous, and, moreover, proceeding from the crown of the 
mature bulb.

HIS beautiful plant is an old inhabitant of our gardens, but is not so much 
grown as it deserves to be. Its deep red flowers, when fully expanded, 
have a very striking and beautiful appearance. The flower-stems are pro¬ 
duced from the sides of the bulbs, so that after the flower produced on one 
side is decayed, another stalk arises from the other side of the bulb ; but there 
is usually only one flower produced from the same stalk. They will flower two or 
three times in a year, and are not regular to any season; but from March to the 
beginning of September the flowers wiU be produced when the roots are in vigour. 
It will grow and flower pretty well in a greenhouse, but will not flower so often, 
nor send out so many offsets as when grown in a stove. It delights in a rich, 
sandy soil, with plenty of heat and moisture during the growing season. The 
great art in cultivating this and all other bulbs is to secure vigorous leaves, as on 
these depend the quantity of organised matter prepared and stored in the bulb.
