species of LorantJius alluded to, wliieli, to rendoi' them still more worthy of the attcuiiou of the horticul- 
turist, do not in most cases grow on the top of high trees, where their beauty would be almost concealed to 
the naked eye, and their charms in a great measure lost, but upon low shrubs, and often so near tlie ground, 
that several botanists have been induced to consider them terrestrial plants. But about their parasitism 
there can be no doubt. Griffith once thought that ho found a terrestrial Lorantlnis (referred to in liis Itiner. 
IVotes, p. G3, ^To. 9C1) ; and writing at Jfyrung, he says ; " The vegetation of the hills about here is much 
the same as about .Moflong. . . . The most curious tree is one which, with the true appearance of an 
Elaagnus, seems to be a LorantJius, the first arborescent species yet found, although, as one or two other 
exceptions occur to parasitism, there is no reason why there should not be a terrestrial arborescent species, 
as well as a fruticosc one." {G?'if. Joum. of Trav. in Ass. etc., J). 1G5.) However, when Dr. ,T. D. 
Hooker and Dr. T. Thomson visited the neighbourhood of Myrung, in the Khasia mountains, the hn-allty 
where that author met witli the strange species, they observed an Elaojfuus with a LoranOiits upon it, the 
leaves of both resembling each other in a remarkable degree, making it highly probable that a parasite 
growing in a similar manner gave rise to the very pardonable mistake of Grillith. Other anomalies of the 
same nature may doubtless be cleared up by a similar course of investigation. I have seen several species 
of ZorantJius with aerial roots, but never one of the roots penetrating into the ground ; and those roots 
T have only observed in climbing species having long slender branches, where they replace in a great mea- 
sure the cirrhi, or hooks, with \Nliich climbing plants arc generally furuished.

"Zauco." Island of Taboga, Proviuce of Panama; probably introduced. 
This specicSj whieli appears to be common in Mexico, and ^N'as also found by Guilding iu St, Vincent, 
one of the AVest India Islands, comes close to S, Canadensis^ Linn,, from which it is distinguij^hod by having 
hairs upon the leaves, and being destitute of glands at the ba^se of the primary segments of the leaves. 
Future investigations must show whether these characters can be relied upon, and whether the two species 
are really distinct. S, Canadensis is met with in California, close to Mexico, and the glands are not always 
present in that species.
