threadlike subterminal appendages, which may perhaps be assumed 
to aid in their dissemination and lodgment after discharge. In 
crushed specimens these appendiculate terminal buds predominate, 
entire spores being comparatively infrequent. 
That these extraordinary spores owe their peculiar structure 
at maturity to a specialization of the phenomenon which occurs 
in so many species of Taphrina, and which, through the budding of 
the primary spore, fills the ascus with yeastlike elements, seems 
highly probable; yet it is very remarkable that a phenomenon 
which, in other instances, is wholly indeterminate in character, 
the yéastlike elements being produced without regularity as to 
number, association, or differentiation as to function, should, in 
the present instance, be replaced by such a definite association of 
buds, which not only differ from one another in form and function, 
but are constant in number as far as the terminal buds are con- 
cerned, and at least subconstant as regards the subterminal ones. 
No further development nor any indication of germination in the 
primary buds was seen in any of the material examined. 
The relation of the parasite to its host is a matter concerning 
which I have been unable to satisfy myself. In none of the sections 
examined, which were made from dried material, have I been 
able to detect any signs of fungus filaments penetrating the leaf 
or stem tissues, or extending themselves in any position except 
between the cutis and the epidermis. Nevertheless, the fact that 
all the adjacent leaves in branchlets of considerable size are com- 
pletely involved, would point to the perennial nature of the disease, 
which may be presumed to extend from a hibernated mycelium 
in the young shoots to the unfolding leaves. 
This species was subsequently found in abundance, not only 
along the ravine above mentioned, but on the larger trees of the © 
forest, especially on the lower branches of such as grew along 
the margins of the open swampy glades characteristic of the region 
where I collected. It was also found less abundantly in the coastal 
region, not only on Nothofagus antarctica var. bicrenata, but also 
on the so-called var. uliginosa, a tree quite different in habit, leaves, 
and fruit, and growing in scattered colonies, especially to the south 
of the town of Punta Arenas. I may mention, in regard to these
