stigmas of at least a few of the flowers at the right time to bring 
about cross-pollination. 
In order to determine whether cross-pollination had occurred, 
the seed from the female parent was collected and later germinated 
in sand under favorable conditions. If cross-pollination occurred, 
leading to the production of hybrids, it was expected that two 
types of seedlings from seed of the same head would be obtained, 
most of them being green, having developed from self-pollinated 
flowers, this being the characteristie color of the female plant. A 
few seedlings, however, due to the presence of the foreign pollen, 
would be red, and consequently hybrids. 
The method proved entirely successful and, with comparative 
ease, we were able to obtain a large number of hybrids between 
different varieties. The obvious limitation of the method, of 
course, is that the green seedling variety must in every case be 
used as the female parent. 
Beardless Tris Project 
The Iris season of 1930 was spent in Japan, an account of which 
has been published in the Brooklyn Botanic Garden Recorp, 19: 
257-208, November, 1930. During our stay, we were able to 
visit a great many gardens where the Japanese Iris were grown. 
Valuable information regarding the culture of the Iris, the varie- 
ties grown, and the history of the Iris, was obtained. We also 
secured numerous photographs of different gardens, and made 
arrangements for the importation of special varieties. We have 
also arranged for the collection and forwarding of seed of the 
wild Iris from a number of different places in Japan. 
In our own collection, many of the varieties bloomed satis factor- 
ily. Practically all of them, however, had been transplanted in the 
fall of 1929, and the best bloom is not likely to be obtained in the 
following year. The plants, however, came through the more or 
less adverse season of 1929 in fairly good shape. 
A few additions to the collection have been made: Two varieties 
of Japanese Iris were received from Prof. Frank T. McFarland, 
Lexington, Ky. Mrs. Wheeler HH. Peckham, New Rochelle, N. 
Y., sent us twelve species of Beardless Iris from the collection at 
the New York Botanical Garden, which, for the most part, have 
heen recently described by Dr. John K. Small. Dr. Charles F.
