cup-shaped disk, in the bottom of which the ovary is placed ; 
the fifteen stamens are in five phalanges, three being fixed bi- 
serially upon each angle of the disk, two of them more inter- 
nally than the other, the filaments rising out of as many pro- 
minent foveated articulations ; and in this manner all the sta- 
mens are opposite to the sepals and none face the petals. In 
Friesta the twelve stamens are arranged in a single whorl op-. 
posite to the sepals and petals alike, and they are fixed around 
the ovary within and independent of the fleshy glands. The 
difference is, therefore, that in one case the stamens are borne 
upon the disk, and in the other are situated within the disk. 
In Aristotelia the fruit is extremely baccate, the mesoderm 
being copious, fleshy, and capable of fermentation ; so that the 
berries are used by the natives of Chile in the fabrication of a 
kind of wine, of which they are very fond. In Friesva the 
fruit, though indehiscent and of similar form, has a dry testa- 
ceous pericarp. It is three-celled in the former, 4-locular in 
the latter. 
In Aristotelia the outer fleshy integument of the seed is 
furnished, below the hilum and above the chalaza, remote 
from both, with an enlargement in the form of a horny laminar 
prolongation, decurrent for some distance, and then arched 
over involutely ; it appears like a sacciform duplicature of the 
integument, filled with long corneous cells. Where only one 
seed is perfected, this process is either superior or inferior, 
according as the upper or lower ovule is fertilized; when two 
seeds are matured, which are always superposed, the process 
is seen upon one seed on the right hand of the line which se- 
parates them, and upon the left in the other. This appendage 
is not unlike that figured by Gaertner in Ganitrus (Hleocarpus 
serratus), 11. p. 271, tab. 140, and is often seen in the seeds of 
Eleocarpus and Monocera: it has not before been noticed in 
Aristotelia by any botanist, except Prof. Agardh, who, in his 
‘Theor. Syst.’ p. 276, alludes to it as appearing upon the 
“putamen.” In Friesia the corresponding fleshy tunic is 
quite smooth, without any such appendage. 
In Aristotelia the second or osseous tunic is externally quite 
smooth ; in /riesa it is always very tuberculated. 
It appears to me, therefore, that with so many and such 
prominent differences of structure, it must be conceded that 
Friesia has little to justify its amalgamation with Aris- 
totelia. It offers a much closer approximation to Vadlea. 
Gay states that in Aristotelia the typical plant has velvety 
stipules, which are very caducous. I have never perceived 
any indications of them; and they do not appear in the 
drawing I made of the hving plant forty-five years since.
