The tuberous-rooted Commelina is a native of Mexico, and in this country requires the treatment of a hot-house herbaceous plant. It is an old, but not common inhabitant of the British gardens; thrives well in rich earth, and is propagated by dividing the tubers of its root, when in a quiescent state; at which period much water is particularly inimical to it.
The genus Commelina can only be distinguished from Tradescantia when the flowers are open; but nevertheless differs very sufficiently, not only in having double the number of stamina, but more especially in the extraordinary cruciform nectaries.
Our drawing was made from very complete specimens communicated to us by the Hon. W. H. Irby, of Farnham Royal, Bucks.[Pg 79]
