type—known generally as geraniums—and seem to have 
been derived, according to Bailey, from the parents Pelar- 
gonium zonale and P. inquinans. Work in hybridization 
has, however, been carried on with other species of Pelar- 
gonium and has resulted in the several varieties of ivy-leaved 
geraniums, show, or fancy, pelargoniums, and scented-leaved, 
or rose, geraniums. 
Despite this large assemblage of horticultural varieties, 
commercial growers have largely confined themselves to a 
few of the more commonly grown forms, and in St. Louis 
at the present time geranium culture is limited to a very 
small collection of varieties. No systematic effort has ap- 
parently been made in this locality to test out the numerous 
varieties of geraniums with a view toward adding new and 
desirable forms to the list of varieties at present known to 
be suitable for growing in St. Louis. The Garden, there- 
fore, is testing out during the present summer some 367 
recently-purchased varieties of geraniums. They will be 
carefully observed and studied as to heat and drought resis- 
tance, profusion of flowers, color, shape and size of flower 
clusters, character of foliage, etc. These varieties are at 
present growing in trial beds along the main walks in vari- 
ous parts of the Garden. One long bed south of the main 
gate contains at least one specimen of practically each of the 
367 varieties at present under observation in the Garden. 
It is hoped that in this large number of varieties some will 
prove to be valuable additions to the at present small list of 
available forms for planting in St. Louis. The results of 
the trial will be announced in the Butiertn after the obser- 
vations have extended over a sufficient length of time. Al 
though the results of these experiments will be of particular 
value in St. Louis, it is hoped that they may be of service also 
throughout the southwest. As is well known, however, the 
success of a plant in one locality does not always insure its 
success in another, although the conditions in the two may 
seem, in general, very similar. 
The following is a list of the varieties of geraniums at 
present growing in the Garden:
