To the senna family belong the sennas or cassias, a showy 

 representative being the American senna, a native of North 

 America ; this family being also largely of warm temperate 

 and tropical distribution, many other species may be found 

 in the conservatories. To the right of the mimosa family 

 may be found the bed devoted to the pea family; to this some 

 of our most valued economic plants belong, such as the pea, 

 the bean and the clover; to the pea family belong also the 

 baptisias, the bush-clovers, the vetches, the tick-trefoils and 

 many other familiar plants. 



Next in the order of sequence is the geranium family, to 

 which belong the geraniums or crane's-bills; the plants so 

 often cultivated in the house under the name of geraniums, 

 but which are not hardy out of doors in our climate, are really 

 not what they are called, but are truly pelargoniums, a closely- 

 related group of plants belonging to the same family; besides 

 our common wild geranium or crane's-bill may be found, 

 among other plants here. A little farther on, near the brook, 

 may be found the bed devoted to the wood-sorrel family, often 

 called sour-grass by children; several species are shown here. 

 Just to the left of the geranium family is the flax family, to 

 which belongs the flax plant (Linum) , from the fiber con- 

 tained in the stem of which linen is made. Beyond this is the 

 bed for the rue family; to this belong the common rue, of 

 southern Europe, and the fraxinella ; this family also includes 

 the oranges and lemons, specimens of which may be found in 

 the conservatories, and a very great number of tropical trees 

 and shrubs. To the right of this is a small bed devoted to the 

 milkwort family. The spurge family is in a bed just to the 

 left of the flax family; the flowering spurge, from the east- 

 ern United States, and the cypress spurge, from Europe, but 

 sometimes found wild in this country as an escaped plant, 

 are both here. Along the edge of the brook, and opposite 

 the spurge family, may be seen the water-starwort family, to 

 which belong a number of small aquatic plants. About oppo- 

 site this, and at the base of the rocky ridge to the right, are 

 two representatives of the box family, in the trailing pachy-
