belonging to this family are the houseleeks (Sempervivum), 
of which there are many representatives, all from the Old 
World, however, as these plants are not indigenous to the 
New World. Many other species of this family, not hardy 
in this latitude, may be found in the conservatories. 
Across the path from the orpine family may be found the 
three beds devoted to the saxifrage family. The heart- 
leaved saxifrage, with its large, thick leaves, from Siberia, 
is one of the showiest plants here, sending up its large 
masses of pink flowers early in the spring, so early some- 
times that they are nipped by the frost. Among other 
plants here may be mentioned: the alum-root, from the 
eastern United States; the two-leaved bishop’s-cap, from 
the northern United States; the Japanese plant, Rodgersia; 
and the shield-leaf saxifrage, from the western United 
States. Menzies’ saxifrage, from western North America, 
is interesting from the fact that in late summer and fall it 
produces small plants at the base of the leaf-blades. 
To the herbaceous members of the rose family are al- 
lotted five beds, located to the left of the saxifrage family. 
Many species of cinquefoils and agrimonies may be found 
here; of the strawberry (Fragaria) there are several species 
represented; the lady’s-mantle, from north temperate 
regions, the various species of avens, the goat’s-beard, the 
burnets and many others, are of ae oe value or ae in- 
terest for other reasons. The roses, blackberries and rasp- 
berries, also members of this oa. are shrubs, and may 
e fice at the fruticetum. The mimosa family has 
relatively few representatives in temperate regions, most 
of its numerous members being confined to warm temperate 
regions and to the tropics; many of these may be found in 
the conservatories. 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
