4. Vitis inconstans, Mig. (Japan and Himalayan sp.) 
B. Inflorescence thyrsoid, paniculate or rarely racemose; petals 
cohering into a calyptra which falls at flowering. 
a. Leaves more or less hirsute on the veins below, or rarely 
all smooth. 
5. Vitis vulpina, L. 
b. Leaves all, or at least the younger, densely tomentose on 
the lower surface. - 
6. Vitis Labrusca, L. 
The wonderful tendency of our vines to vary under cultivation © 
seems to belong to them in the wild state, and one who has buta 
small suite of specimens is likely to be much more positive in his 
determinations than those who have collections made from widely- 
separated localities, 
Since the above was in type we learn from a note in the Garden- 
er’s Chronicle that Dr. Regel considers Vitis vinifera to be a 
hybrid between V. Labrusca and V. vulpina. He bases this 
opinion upon the fact that V. vinifera is not found in a truly wild 
state, but only as an escape from cultivation, and that these species 
are natives of the countries where the cultivated grape originated. 
It may be remembered that our grape growers who have experl- 
mented in the production of hybrids have found V. vulpina the 
most intractable of all in this respect. eae 
§ 69 Two New Fungi from New Jersey.—Some time ago Mr. J. 
C. Martindale sent me Specimens of the common dodder, Cuscuta 
Gronovii Willd. that were much hypertrophied. -Whole clusters 
of the flowers were swollen and elongated and parts of the stems 
were much enlarged. The affected clusters were of a paler color 
than the unaffected, though in some cases the process of decay had 
advanced so far that the diseased plants had become dark-colored 
and were supporting a crop of that almost omnipresent blackish 
mold, Cladosporium herbarum Lk. The inner. tissues of the af- 
fected plants were all broken up, or destroyed, and the cavities 
filled by innumerable fungus spores, which in the mass were of a 
whitish color, but under the microscope wefe seen to consist of @ 
pale or yellowish endochrome surrounded by a thick hyaline eps .— 
pore. Here was the secret of the strange appearance of the dod- the 
der. Tt was nourishing a parasite within itself that was preys 
upon its vitals. I do not find the epidermis ruptured in any of the 
specimens, from which it is probable that the fungus spores must 
wait for their liberation and dissemination till the decay of the ev 
closing walls of their habitation takes place. This fungus is refer- 
able to the genus Protomyces, but is peculiar by reason of the x 
abundant formation of spores in all parts of the affected plant. | 
Deeming it a new species, I take great pleasure in dedicating ” 
to its discoverer. es 
Protomyces Martindalei P%.—Host plant swollen, slightly dis- 
colored ; spores abundant, produced in all parts of the host plant, 
al ways covered, globose, whitish in the mass, .0006—.0007 inch 
in diameter, epispore thick, hyaline. ;
