A joint meeting of the Horticultural Society of New York and 
the American Rose Society was held at the Garden June to. 
An exhibition of lantern slides was given by Mr. Leonard Barron, 
showing types of roses for various purposes. The usual exhibi- 
tion was held June ro and 11. 
Volume 22, part 3, of North American Flora appeared June 
12, 1908. This pait contains descriptions of the Grossulariaceae 
by F. V. Coville and N. L. Britton; the Platanaceae by H. A. 
Gleason ; the Crossosomataceae by J. K. Small ; the Connaraceae 
by N. L. Britton; the Calycanthaceae by C. L. Pollard; and 
the Rosaceae, in part, by P. A. Rydberg. 
An important addition to the literature of the fleshy fungi has 
recently been made by Miss Gertrude Burlingham, now of the 
gill-fungi having a milky juice. The results of her studies ap- 
peared May 26 as a memoir of the Torrey Botanical Club (14: 
I-109. f. 1-15. 1908). The descriptions and notes are very 
complete, and the illustrations, from photographs by the author, 
are excellent. A feature of great value to collectors is a con- 
densed description of each species when fresh with distinguishing 
characters to be used in the field. Seventy-one species are rec- 
ognized in the United States, six of these being described as new. 
The process of enriching soil by the growth of crimson clover 
is being tried this spring on about half an acre of land immedi- 
ately behind the museum building, and the growth of the crop 
may readily be watched, the field being in full view from the 
windows of the systematic museum. The clover seed was sown 
May 14, the plantlets began to appear above ground on May 20, 
and the first foliage leaves were developed by May 30. An ex- 
amination of the little plants on June 2, when they were about 
an inch high, showed the roots already provided with tubercles 
containing the organisms which concentrate nitrogen. A com- 
plete account of the development of the plant and of the cost of 
the work on this field will be published in a subsequent number 
of the JouRNAL.
