In Gallery F were the botanical exhibits and chief among Evolution 
these was a case showing important steps in the development of of the 
the Eose flower, from spore plants to flowering plants, by means r se 
of drawings, pressed specimens and was models, thns develop- 
ment was shown : the models of a Batter cnp and a Pear-blossom, 
each a foot in width, showed the structures of these flowers and 
a few sentences below each explained their position in the 
gradual change of type. Below the Pear-blossom, for example, 
were these words : ' ' Here and in the Apple there is a closing-in 
around the carpels by the walls of the hollowecl-out receptacle 
such as is typical of the hollowed fruit (haw) of the Roses. In 
the Pear and Apple the walls of the receptacle ripen along with 
the enclosed carpels and form what is ordinarily called the fruit. 
Thus the Pear represents a modification from the stage repre- 
sented by the Eose — that is, it is one step more highly developed. 
The method of seed formation in the single Eose was shown : 
and the following highly interesting paragraph summed up the 
botanical truths of this beautiful exhibit : "In the double rose, 
man's care often stimulates the remainder of the stamens and 
often the carpels also, to become petals as did the outermost 
stamens in the earlier steps in this evolution of the flower. This 
of course means that the Eoses could not produce seed and must 
die out for lack of descendants. Man, however, remedies this 
by propagating from cuttings or other methods of vegetative 
production. ' ' 
Great pains were taken by the Director and his associates to 
make this exhibit perfect and it was an object of special interest 
to the members. 
Among the models of gardens, that by Miss Whitehead of Models 
the gardens of the Generalife at Granada, a model about three 
feet square, was a charming example of such work. The terraces, 
pools, sub-tropic plant subjects, were all reproduced with a nice- 
ness of detail down to the balanced formal beds on the high 
terrace with their two small fountains, and the grouping of 
Cypresses on the terrace at right-angles to this one. The con- 
struction of the beautiful loggias or arcades was a thing to 
remember, and this model was particularly pleasing because of 
the present-day interest in Spanish gardens. One could not 
help noticing the clever use of all kinds of material in this model 
— painted lufa sponge for Cypresses; a corrugated board, 
painted, for the tiled roofs, etc. 
The model of Hampton Court, on even a smaller scale, 
brought forth a great deal of interest too. Both these models 
were made by members of the Garden Club of Allegheny County. 
With such talent, these two artists should some day make an 
original design for a garden and use the ideas which we know 
must be lying dormant in their "gardening brain."
