in Myzodendron punctulatum , Banks et Sol . 203 
latum. I luckily found three seedlings which were germinat- 
ing on a branch of M. punctulatum itself, probably on their 
parent plant. Externally they were like the seedlings of 
M. brachystachyum , the radicular end was swollen and 
flattened, and made nearly a right angle with the curved 
elongated hypocotyledonary stem. The lengthened cotyle- 
dons were still enclosed in the shrivelled remains of the 
endosperm. Dissection of the seedling showed a well- 
developed axial vascular strand ; stomata, as seen on the 
mature stem, were marked out on the hypocotyledonary stem, 
and there was no tendency to a separation of the outer layers 
of the embryo from the central parts, as seen in M. brachy- 
stachyum. The radicular part of the seedling was decayed 
and had only just begun to penetrate the branch. This 
decay may have been due, partly to the very thick outer 
epidermal wall of the branch, and partly to the fact that the 
seedling’s host was a branch of M . punctulatum. In Cuscuta , 
which will not 1 , as a seedling, climb round a dead support, 
one may see many examples of two branches twining round, 
and sending haustoria into one another. Solms-Laubach 2 has 
examined the mode of attachment of M. punctulatum to the 
host branch, Fagus Dombeyi. From his description it seems 
the intra-matrical thallus of M. punctulatum differs somewhat 
from that of M. brachystachyum described in the Flora 
Antarctica. ‘ The Valdivian plant Myzodendron punctulatum , 
which has already been mentioned occasionally, joins on here 
in the structure of its solitary terminal haustorium (Plate 
xxiv. Fig. 4). The relations known in Loranthus Sternber - 
gianus are repeated in a smaller way. The branch of Fagus 
Dombeyi is irregularly thickened at the place of attachment 
of the parasite ; there is no indication in this species of the 
wood-cups described by Hooker for M. brachystachyum , DC. 
The sucker-outgrowth spreads out in the host cortex into an 
irregular mass sending off short, root- like branches. From
