the appearance of being trimmed by art. Passienus Crispus, 
the orator, who in our time was twice consul, and afterwards 
became still more famous as haying l^ero for his step -son, on 
marrying his mother Agrippina, was passionately attached to 
a fine tree that grew in this grove, and would often kiss and 
embrace it : not only would he lie down, too, beneath it, but 
he would also moisten its roots with wine.'''^ In the vicinity 
of this grove there is a holm-oak, likewise of very considerable 
celebrity, the trunk of which is no less^^ than thirtj^-four feet 
in circumference ; giving birth to ten other trees of remarkable 
size, it forms of itself a whole forest.

It is a well-known fact that trees are killed by ivy.'^ The 
mistletoe also has a similar influence, although it is generally 
thought that its injurious effects are not so soon perceptible : 
and, indeed, this plant, apart from the fruit that it bears, is 
looked upon as by no means the least remarkable. There are 
certain vegetable productions which cannot be propagated in 
the ground, and which grow nowhere but on trees ; having no 
domicile of their own, they live upon others ; such, for instance, 
is the case with the mistletoe, and a herb that grows in Syria, 
and is known as the cadytas."'''^ This last entwines around 
not only trees, but brambles even ; in the neighbourhood of 
Tempe, too, in Thessaly, there is found a plant which is called 
*'polypodion the dolichos"^^ is found also, and wild thyme. 
After the wild olive has been pruned there springs up a plant 
that is known as phaulias while one that grows upon the

'2 Fee says that no holm-oak is ever known to attain this size.

Sprengel says that this is the parasitic plant, which he calls Gassy ta 
filiformis. Fee says that this opinion, though perhaps not to be absolutely
