MISSOURI BOTANICAL GARDEN BULLETIN 43 
Another interesting example is the Chinese maidenhair 
tree (Ginkgo biloba), standing a few feet east of the path that 
leads from the main conservatories to the floral display house. 
In this case a bridge graft has been formed by a small branch 
which has developed from the trunk, and, turning up and 
inward in its growth, has united with the juncture of two 
larger limbs with the main stem: (Plate 10, fig. 2). . This 
graft is seen to greatest advantage from the southeast. All 
the examples cited can be best observed during the season of 
defoliation. An unusual type of self-grafting is shown in 
Plate 11. In this case a branch has grown between two 
smaller ones and has united with them at the fork.

FLORAL DISPLAY FOR MARCH 
At the end of February the present collection of flowering 
plants in the floral display house, consisting of poinsettias, 
rhododendrons, azaleas, etc., will be removed, and an entirely 
new show installed for the month of March. The new dis- 
play will be composed mainly of the many varieties of 
cinerarias. The great difference in habit and color of the 
_ flowers has made these plants immensely popular for dis- 
play purposes, and the Garden is showing some 2000 speci- 
mens this season in the hopes of presenting an exhibit which 
will rival that of the chrysanthemums in November. Cin- 
erarias, in many ways, resemble the single-flowered chry- 
santhemums, but far surpass them in the brilliancy of the 
floral coloring, white and all shades of red, blue, and purple 
being included. In the new floral display house these plants 
will be seen to better advantage than ever before. 
In addition to the main exhibit, as indicated above, there 
will be shown a number of plants of astilbe, a white or pinkish 
plume-like flower, and some genistas, yellow-flowering plants, 
which have been clipped to take the form of the common 
round bay-trees. Later in the month a large variety of snap- 
dragons or antirrhinums will be on display, and these, with 
the calceolarias, are to be transferred to the flower alcoves 
of the aroid house during the latter part of April. In the 
same alcoves many orchids, such as Cattleya labiata, C. 
Mossiae, and a variety of cypripediums or lady slipper 
orchids, are now in flower. 
This exhibit in the floral display house will be replaced 
during the last week of April by the Shakespearean garden, 
referred to elsewhere in the BULLETIN.
