Viticetum. This collection remains about as it was. 
Conservatories, 
The arrangement of the collections here installed remains 
essentially the same as last year. Many genera, species and 
varieties not hitherto represented have been added. The 
tree-fern collection has been notably increased, the explora- 
tion in the West Indies during the past year having added 
many interesting members to this graceful group. Many of 
the additions in other groups have also been derived from 
this source, either imported direct as living plants, or 
grown from seeds collected in the region by the expedi- 
tions which have visited it in the interests of the Garden. 
The conservatory collections, including those species and 
varieties temporarily at the propagating houses, now embrace 
1588. ere are now in the conservatories 12,921 plants, 
distributed as follows:

The rapid growth of the collections, both in increased size 
of individuals and in the greater representation of species, 
has made it necessary to dispose of many duplicates during 
the past year, but the conservatories are still too crowded, 
and more material must be disposed of to give the rapidly 
growing plants room for expansion. More space is required 
to accommodate the collections here instaJled. 
In the following table will be found the number of species 
in some of the larger or more conspicuous groups. For the 
sake of comparison, the same families are selected as were 
chosen last year for this purpose:
