R. lilacina, Hooker in Bot. May. t. 4147. 
We have to correct a great error into which we fell, when, 
in an early number of the present volume, we referred this 
plant, Sir Wm. Hooker's Ruellia lilacina, to the so-called 
R. longiflora of the Gardens. It now turns out that we had 
not seen this, the real R. lilacina, at the time when we fell 
into the mistake, and we allowed ourselves to be misled by a 
certain similarity of appearance in the drawings of the two 
plants, a great resemblance in their leaves, and by their having 
been both obtained from Mr. Glendinning’s Nursery. 
We now, however, find, that in truth the two plants are 
wholly different; and that, while the species formerly figured 
has large panicles of flowers, the present, in all respects
