trip to the island. It was found twining with profusion of white flowers 
on a large trunk of a species of (if I am not mistaken) Qwercus. Another 
speeimen of the plant with fruits was collected by Mr. T. Dor in the central 
part of the island. It is stated by BrwTHaM that the species has a. 1— 
celled-ovary, while my plant has, as I have assured several times, distinctly 
4-celled-ovary, each cell having 1-ovule. 'Phe Formosan plant has much 
longer panieles than that deseribed by DrwTrHAwx. Phe shape of the embryo 
is very striking. "Phe cotyledons are very irregularly lobed and plicated, bent 
accumbently and touch closely to the very short radicle. "The relative posi- 
tion of the eaudicle and radicle is also very peculiar. "Phe former lies not 
at the foot of, but on the side of the latter. It is, therefore, conceivable 
that the embryo describes a semi-cirele on itself, and brings the caudicle 
Írom the foot of the radiele to the side of the latter.
