122 MISSOURI BOTANICAL GARDEN BULLETIN 
the plants to France, and as each of them had cost him 
120 frances, or forty crowns (quarante écus), this was the 
origin of the name applied to this tree, and not because it 
was originally sold for 120 francs a plant. Almost all the 
inkgo trees in France have been propagated from these 
ve imported from England by M. Pétigny. He gave one 
of them to the Jardin des Plantes, which was kept for many 
years in a pot and preserved through the winter in the 
greenhouse, till 1792, when it was planted out by M. André 
Thouin, who gave the above relation in his lecture; but as 
the situation was not at all favorable to it, this plant was 
not much above forty feet in height in 1834, a had not 
then flowered.” 
~The ginkgo is easily propagated by budding or grafting, 
and, when possible, this method should be employed, be- 
cause, of course, by this means female trees can be elimi- 
nated, thus removing the only possible objection to the 
tree. However, since the seed germinates so readily, most 
ginkgo trees are grown from seed, and it is well worth the 
while of Liter? Kas interested in trees to plant a few seeds of 
this unusually fine tree. While the Missouri Botanical 
Garden cannot undertake to send out seed, the surplus 
ginkgo fruit obtained from the trees in the Garden will 
be distributed this fall to those inquiring for them at the 
main gate. The seed should be kept dry during the winter 
and planted out early the next spring. A tree from eigh- 
teen inches to two feet in height may be expected the first 
season. 
TWENTY-FIFTH ANNIVERSARY CELEBRATION 
As announced in the Butiterin for August, 1914, the 
Twenty-Fifth Anniversary of the organization of the Board 
of Trustees of the Missouri Botanical Garden was celebrated 
at the Garden on October 15 and 16. Although the foreign 
disturbances made it impossible for a considerable number 
of the European delegates to be present, the occasion proved 
to be one international in character and scope. 
The following European botanists had originally accepted 
the invitation of the Board of Trustees to be present at the 
celebration and read papers at the scientific meetings: 
Director J. Briquet of the Jardin Botanique de la Ville 
Genéve, Geneva, Switzerland; Professor Frederick Czapek 
of the Physiologisches Institut der Kaiserlich-Kénig- 
lichen Deutschen Universitat, Prag, Austria; Director Hans 
Fitting of the Botanische Anstalten der Universitit Bonn, 
Bonn, Germany; Assistant Director Arthur W. Hill of the
