"P. E." says: "I notice you spell this plant Virgilia. It is now clearly demonstrated that the poet's name was Vergil, and, as I suppose our plant was named in his honor, it should be written Vergilia."

[We did not know it was so " clearly demonstrated." The matter has been gone over long before " P. E." was born. There appears to have been some reason for the choice of e for i, but no more than for the same in Diana, Minerva, and numberless Latin words. But the world has not adopted "Deana" or "Menerva," nor do we see why " Vergilia" should be the single exception.

In relation to " our plant," however, the matter is soon settled. It was a mistake to refer it to that genus. Its right name is Cladastris tinc-toria - Ed. G M.]
