wood specimens are added specimens of twigs, of flowers,

2. THE MUSEUM OF SYSTEMATIC BOTANY 



This occupies the second floor of the building, except the 

 west wing, and is designed to illustrate by specimens, draw- 

 ings, and photographs, types of all the natural families of 

 plants, beginning with those of the simplest structure and 

 ending with the most complex. It consists of four series of 

 objects: 



(a) The general synoptic collection 



(b) A series of microscopes showing selected specimens 



(c) Illustrations of the local flora 



(d) Plant photograph exhibit 



(a) Synoptic Collection. This is designed to illustrate 

 the plant world. A series of characteristic objects is 

 installed as a basis for illustrating each plant-family. 

 These specimens are accompanied as far as possible by 

 plates, drawings or photographs, while on the shelves are 

 arranged additional objects, such as flowers, fruits, woods, 

 specimens of fossil plants, and models of various organs of 

 plants, all intended further to illustrate the structural 

 characteristics of the different groups. This collection is 

 arranged according to the most natural and thus far most 

 generally satisfactory interpretation of the interrelation of 

 the plant-families; it may be considered as falling into 

 two main series, namely, the flowerless or spore-bearing 

 plants and the flowering or seed-bearing plants. 



The flowerless plants fall into three phyla or subking- 

 doms: (i) the Thallophyta, in which the plant-body is not 

 differentiated into stems and leaves, as represented by the 

 slime-moulds, the bacteria and other micro-organisms, 

 the seaweeds, the fungi, and the lichens (2) the Bryophyta, 

 represented by the mosses and their immediate relatives; 

 and (3) the Pteridophyta, including the ferns and the 

 fern-allies.
