acid. The berries yield a fine purplish juice, but the coloring 
principle cannot be applied to useful purposes in dyeing from the 
difficulty of fixing it. The seeds contain a neutral principle in silky, 
lustrous crystals, which is called Phytolaccin; the juice of the berries 
contain phytolaccic acid. The roots and leaves, especially whenfresh, 
are emetic, purgative, and somewhat narcotic. Phytolacca is, more- 
over, known as a pot-herb, since the young shoots are eaten like 
asparagus, but only in the early season. 
Among the structural peculiarities are described some very 
peculiar hairs that abound on the peduncles of the flowers; the 
occurrence of styloids in the leptome; the tuberous root with the 
development of several concentric bands of mestome-bundles during 
one season. The st.em is described by Solereder as possessing an 
anomalous structure in regard to the arrangement of the mestome- 
strands. However in the American plant no anomaly was observed 
in this respect, since the mestome Strands are collateral and located 
in one single circular band. On the other hand the pith shows a 
very remarkable structure, which is not mentioned in Solereder’s 
work, although it was described already by Mirbel (1815.) The 
pith is discoid and shows cavities of enormous width, a structure 
that is seldom observed in herbs, for instance: Begonia, Pedalimn, 
and Diplotaxis, but in several trees e. g.: Juglans , Nyssa etc.
