This is a deserving companion of the beautiful Eustoma Russellianum, better 
known as Lisianthus Russellianum. It is unlike that species in its whole parts being 
smaller, and resembles it in being wholly of the same glaucous hue, grows erect, as 
it does, and produces its flowers in the same manner ; but they, in addition to being 
smaller, have a whitish blotch at the base of their petals. Various names have been 
given it by different botanists ; some account of them may be found at page 70 of 
our last volume. The present is accorded it by Dr. Lindley, as the one it justly 
ought to bear. 
The same species, or slightly differing varieties, have a very wide botanical range 
in North America, numerous stations in which continent are recorded where such 
have been found. Near half a century has elapsed since it was first known, but as 
an object of culture it has only recently attracted attention. 
Beautiful and well-known as is E. Russellianum, its splendour is seldom developed 
by cultivation. Neither have we yet seen our present subject, its kindred species, 
occupying that position it is entitled to as an ornamental plant. The great mistake 
in their treatment arises from regarding them as annuals : though they may be so, 
naturally, no good is achieved by cultivating them as such. They properly should 
be considered biennials, and their seeds carefully sown in gentle warmth, in late 
summer or autumn ; and when up, ought to be potted before they become the least 
drawn, and, if possible, kept steadily growing till they flower. Previous to their 
doing so, however, considerable skill is required to keep them healthy, and induce
