half of these were replacements. Four groups with which | have 
for some time been occupied are lilacs, conifers, maples, and

rerbaceous plants; these have been planted near the south end of 
the nursery. Seventy-five plants from the nursery were given to 
the Dutch Garden, New City (Rockland County, N. Y.), through 
Mrs. Mowbray Clark. 
HERBACEOUS PLANTS 
The herbaceous beds are now approximately filled, but much 
improvement is possible in the way of greater diversity or to get 
species or varieties more desirable than those we now have. As 
an example, we now have about twenty species of Dianthus, and 
about forty species of Sedim. Several of these are closely alike 
and of doubtful identity. Something like 250 species of Dianthus, 
nearly 300 species of Seduim have been described. Which ones 
ought we to grow? We would prefer those that are attractive and 
at the same time definitely distinct. We can get many through 
the Seed Exchange. But it takes time to know what we want, 
and afterwards to get them, to say nothing of the difficulties of 
getting some of the rare plants established. 
Greater diversity as to moisture, shade, or soil conditions would 
enable us to 
—_— 
qave greater variety. The Rock Garden and the 
Local Flora, with conditions so different from those in the beds, 
form valuable supplements in this respect. 
In the latter part of May a visit was made to the Cronamere 
Nurseries at Greens Ifarms, near Greenwich, Connecticut, to in- 
spect their very fine rock garden and to add material to our own 
collection. 
HERBARIUM OF CULTIVATED PLANTS 
During the past year much of my time has been given, with the 
assistance of Mrs. Margaret Putz, to determinations and improve- 
ment of the herbarium of cu 
oe 
tivated herbaceous plants. 
Our use of half-size sheets followed an excellent suggestion 
made nearly twenty-five years ago by Dr. EF. B. Southwick of the 
New York Botanical Garden. It has greatly simplified the study 
and expansion of our various collections; woody plants, herbaceous 
beds, rock garden, and conservatories. So many species come into
