Lilac. - In addition to the varieties and species of Lilac noticed in the former edition, there are a number of others that are desirable in a large collection.

The variety of the common Lilac with double flowers is very curious, but not so handsome as the single.

Lilac Lady Joseki is a handsome species, flowering nearly a month later than the other sorts, with longer and more open spikes ' of flowers, a little darker than the common lilac, and the whole plant more graceful in its habits.

The Siberian Lilac is another graceful species, with spikes more open than the common sort; color about the same; in flower a little later.
