of several hundred species in convenient form, many of which 
have never been illustrated. 
In the microscopic forms of plant hfe such as the diatoms and 
desmids and other minute algae, in pollen grains, and in the ana- 
tomical structure of plant parts there are numerous other sources 
of design that have scarcely been utilized. One does not need to 
be a microscopist, however, to take advantage of this material, for 
here the adaptations can be made from the multitudinous published 
illustrations. ‘The macroscopic and microscopic fungi and_ the 
mosses, liverworts, and lichens present additional possibilities, as 
do buds and bud scales, leaf scars, the unfolding of young leaves, 
fruits, seeds, and even the structure of plant hairs in the higher 
plants. 
At both of the gardens, as well as at the Horticultural Society 
of New York, reference libraries are maintained, the contents of 
which are available to those who desire access to them.? Being 
specialized, these libraries naturally contain a great many works 
that are not to be found in other libraries in the city. The library 
of the New York Botanical Garden is particularly rich in sets of 
periodicals, in the older illustrated books appertaining to plants, 
including herbals, and in the sumptuously illustrated folios, such 
as complete sets of publications with plates by Redouté, Jacquin, 
Roxburgh, Willmott, Millais, Elwes, Berlese, and Sibthorp 
It is hoped that these suggestions may be of service to that large 
public interested in art, especially to those who wish to study plant 
forms as a basis of design. The resources of the two gardens are 
available to all who by training and experience are equipped to 
take advantage of what they have to offer. Both institutions are 
open every day during the year, including holidays and Sundays. 
and special permits are freely granted to artists who wish to sketch 
in the grounds and in the conservatories.
