The fruit of the Fothergilla, as was long ago sagaciously 
remarked by the celebrated A. L Jussieu, is almost €x- 
actly similar to that of the Hamamelis, but in the flowers 
there exists a strange disparity; by the intervention of thre 
Pachysandra, however, which appears more properly re- 
ferable to the Amentacee, than the Euphorbiacee, and at 
the same time allied both to Hamamelis and Fothergilla, — ; 
we have something lke a connected series. 1n these 3 ; 
genera, the anthers and filaments are united, the anthers 
also become papyraceous, and are for a considerable. 
length of time persistent, not deciduaus as in the Berbe- 
rides. ¥rom the Amentacee, they differ in possessing * i 
_ perisperm, and the Hamamelis is excluded from the 15th - i 
_ class of Jussieu by the existence of petals, but this exceP- 
‘tion is stareely universal, as the order in question in- 
cludes Comptonia, described as having 6 petals, at all 
interior and dissimilar calix. Wherever these 
3 contiguous genera may be placed, either asa distinct 
order, (FoTHERGILLEA) or as a neighbouring section, 
they cannot but be considered as closely allied to the 
Amentacee, notwithstanding the singular construction of 
the anthers in the genus Hamamelis, which is indeed the | 
sole character by which it is in any manner allied to the 
Berberides, the carveous perisperm being equally com- 
- mon tothe Evpherbiacee. There is some reason to sus- :
