sponding diminution in size. By the time that the young plant is furnished 
with a pair or two of leaves the attachment will be found considerably firm. 
If we cut away the portions of the support, and lay bare the included portion 
of the parasite, we find that the application takes place entirely between the 
ligneous systems of both, the fibres of the sucker-like root of the parasite 
expanding on the wood of the support in the form of a pdte d'oie*. There is, 
however, no interchange of structure between them; neither at this period is 
there any intermixture of ligneous fibres. As soon as the young parasite has 
acquired the height of two or three inches, when an additional supply of 
nourishment is probably required, a lateral shoot is sent out, which is, espe- 
cially towards the apex, of a green colour. This at one or two, and subse- 
quently at various points, adheres to the support by means of sucker-like 
productions, which are precisely similar in structure and in mode of attach- 
ment to the original seminal one. 
As the parasite increases in size, these lateral shoots become frequently very 
numerous, and give origin, I believe, always from those parts immediately 
opposite to the sucker-like adhesions, likewise to stems and branches. During 
the same period the fibres of the suckers become more and more imbedded in 
the ligneous system of the support, owing to the deposition of the + ira 
of the latter. The fibres of the parasite never penetrate beyond their original 
attachment, although the later developed fibres appear to have the power » 
arriving at this point, but no further. This is very remarkable. ti 2 —
