REFERENCE TO THE PLATE.

All the species of this genus, yet discovered, are natives of North America, and are considered as hardy herbaceous plants; the winters of this country not being too severe for them; although they are found as far south as Carolina, yet they are more plentiful in Pennsylvania, about Philadelphia. They flourish most in a shady, moist situation; and increase, freely, by parting the roots in the month of March. The flowers are produced in May, the flower-stem increasing in length, till the flowers are entirely decayed. The Helonias bullata has been an inhabitant of our gardens ever since the year 1758, when it was introduced by Mr. Ph. Miller, and cultivated by him at Chelsea. See Mill. ic. 181. t. 272.

Our drawing was made at the Nursery, Hammersmith, in June 1801.
