further on and to the left is the lobelia family; the cardinal 

 flower and the blue cardinal flower, both natives of North 

 America, make showy objects; the former is particularly 

 striking in its rich masses of cardinal-red flowers. 



To the right of the teasel family is the chicory family. 

 The common lettuce (Lactuca) , so much used in salads, be- 

 longs here ; many of the plants are extremely weedy by 

 nature, and this is particularly true of the hawkweeds, a 

 genus richly represented in the Old World, several species of 

 which are shown here; the oyster plant is also a member of 

 this family. 



To the left of this may be found the ragweed family. All 

 the species here are of a weedy nature. The ragweed, the 

 giant ragweed and the common clot-blur find representa- 

 tion here. Terminating the sequence comes the very large 

 thistle family, represented by many species from all parts of 

 the world; there are nine beds at present given over to these 

 plants; the sunflowers, coneflowers, thistles, asters, flea- 

 banes, yarrows, golden-rods, tansies, sneezeweeds, burdocks, 

 artemisias and wormwoods, cat's-foot, tick-seeds, elecam- 

 pane, boneset, chrysanthemums, colt's-foot and many others 

 are shown ; the Jerusalem artichoke, one of the sun-flowers,. 

 a native of eastern North America, bears edible tubers. 



(b) Morphological Garden 



This is located to the north of the systematic collection, the 

 two collections being separated by the driveway which crosses 

 the valley. It is designed to illustrate here with typical 

 examples the organs and other features of plants, including 

 leaf-forms and the various modifications of their margins, 

 their venation and insertion on the stem; also the various 

 kinds of stems, methods of propagation, flower-clusters and 

 fruits, leaf-movements, parasites, desert plants and seed-dis- 

 persal. Looking north on this collection, the first bed to the 

 right of the brook contains plants illustrating simple leaf- 

 forms. Immediately following this on the same side of the 

 brook are the plants representing the various forms of com-
