FAGUS ANTARCTICA OF FORSTER, 153 
I shall terminate this paper with an enumeration of all the 
species known to inhabit the southern hemisphere. In the 
Species Plantarum of Willdenow, Persoon and Sprengel, 
only one is mentioned, and most imperfectly characterized, 
the Fagus antarctica of Forster. Mirbel added four new 
species, of which number he considered one to be doubtful, 
and Dr Poeppig four. The number now amounts to eleven, 
if we are correct in referring the Betula antarctica to this 
genus, of which I think there can be no doubt. It will be 
seen that, with the exception of F. Cunninghami, all are inha- 
bitants of Chili or of the Chilian Andes, and of the southern 
extremity of South America. Mirbel divides the species of 
Fagus known to him, into two groups, as follows :— 
Secr. I. Cupula muricata, capsuliformis ; ovaria inclusa; 
folia juniora plicata. Fagus sylvatica. F. ferruginea, F, 
obliqua. 
Secr. II. Cupula involucriformis, segmentis angustis lacini- 
atis, ovaria lateribus exserta; folia juniora non plicata. 
Fagus Dombeyi.. F. betuloides. F. dubia? 
But in our Australian Fagus, the involucriform cupula, is 
not accompanied by the folia juniora plicata. I shall there- 
fore take the divisional characters from the leaves alone. 
* Folia impari-pinnata. 
l. F. glutinosa (Poep. et Endlich.) ; fruticosa humilis foliis 
impari-pinnatis uni-v. bijugis, petiolis pilosis, foliolis utrin- 
que hirto-pubescentibus glutinosis serratis terminali elliptico, 
lateralibus oblongis basi inaequalibus. Poep. et Endlich. Nov. 
Gen. et Sp. Pl. Chil. &c., p. 68. 
Haz. Fissures of rocks in the coldest regions of the south- 
ern Andes of Chili. Poeppig.—Flowers and fruit unknown. 
** Folia simplicia submembranacea, juniora plicato-venosa. 
2. F. obliqua (Mirb.) ; foliis ovato-oblongis obliquis sub- 
rhomboideis obtusis duplicato-serratis, basi integris in peti- 
olum attenuatis pilosiusculis, perianthiis masculis solitariis 
hemisphzericis sinuatis 30—40-andris, cupulis capsulifor- p
