p. 301. 
Engravings. Mém. Mus., 14. t. 24.; and our jig. 1704. 
Spec. Char., §c. Leaves ovate-lanveolate, some- 
what rhomboid, pointed; serrated, coriaceous, 
shining, glavrous ; wedge-shaped, and_ oblique 
at the base, on very short footstalks. Perianth 
of the male ternate, campanulate, 4—5-lobed. 
Anthers 8—10. Cupules involucriform, smooth, 
‘+-partite ; segments almost linear, laciniate. 
Ovaries laterally exserted, 3-sided ; angles mar- 
ginate. (Mird.) A tall tree, a native of Chili, 
where it was found, along with F. obliqua, by 
the botanist after whom it had been named. 
Whether it is deciduous or evergreen we are un- 
certain ; there being no living plants of it either 
Lok 4 wait in France or England. 
2. F. pu'Bia Mirb. The dubious Beech. 
Identification. Mém. Mus., 14. t. 26. 
Engravings. Mém. Mus., 14. t. 26.; and our fig. 1705. 
Spec. Char., &c. Leaves ovate, bluntish, doubly ser- 
rate, coriaceous, shining, glabrous, round at the 
base, on short footstalks. Perianth of the male 
solitary, turbinate, 5—7-lobed. Anthers 10—16. 
(Mirb.) A South American tree, not introduced. 
Probably nothing more than a variety of F. detu- 
ldides. The branches are smoother and more elon- 
gated ; the leaves larger, oval, and not elliptic ; and 
dentate, not crenulate; all which differences may be 
the result of a more vigorous growth. The dried 
specimen, in other respects, perfectly resembles that 
of F. éetuldides ; and Commerson, who gathered it at 
the Straits of Magellan, had placed it along with that 
species, under the name of Bétula antarctica. As 
Mirbel had not seen the female flower, he thought it 
better not to confound it with F. detuldides. 1705. F. dubia

Gen. Char. Male flowers each consisting of a 6-parted calyx, and 10—15 
stamens, affixed to its bottom, and extended beyond its mouth. Flowers 
sessile, and disposed in groups along axillary stalks : each group consists of 
many flowers, and is involucrated by a bractea and a bracteole.— Female 
flowers consisting each of an ovary taper to the tip, clothed with a calyx, 
andecrowned by its 6—7—8-cleft limb, and bearing as many styles, and 
having as many cells, with two pendulous ovules in each. The flowers are
