Digynia, 2 styles or sessile stigmas Trigynia, 3--Tetragynia,4--Pentagynia, 5--Hexagynia, 6--, Observation, Of rare occurrence. Heptagynia, 7------Observation. Still more rare. OcTAGYNIA, 8 Observation. Scarce!' occurs at all. Enneagynia,9------Observation. Hardly an instance known. Decagynia,10--Dodecagynia, about 12 Polygynia, many Observation. 1.

To the fifth Class, Pehtakhma, and to the second Order, Oigynia, belong the great natural family of umbelliferous plants, ot which the Parsnip and Carrot are examples. Class 14, IHdynamia.
