The fruit is a capsule. 
Snowberry (Symphoricarpus) is easily recognised by the white 
berries ; the ovary is 4-chambered, but only 2 ovules are 
developed. The flowers of the Snowberry seem specially 
adapted for wasps: the corolla hangs down; the wasp hangs 
below the flower, thrusting in its head and licking the honey, 
secreted by the swelling at the base of the style. 
The Elder differs from the Honeysuckle in having pinnately 
compound and stipulate leaves; the flowers are small and

leaves; the marginal flowers of 
the inflorescence are usually barren, having neither stamens 
nor styles. These flowers are conspicuous, attracting insects, 
which visit these shrubs far more than they do the Elder. 
The Waytaring-tree (Viburnum lantana) is very woolly, the 
young shoots and leaves being thickly covered with a soft 
mealy down. This tree is the only British shrub that has its 
buds unprotected by scales in winter; the flowers are small, 
but not barren, as in the Guelder-rose. 
Linnwa borealis—the one plant which the great Swedish 
botanist, Linnzeus, would consent to have named after him—is 
a small creeping Alpine plant, found in Scotland and Switzer- 
land, and very occasionally in Yorkshire. It has pink petals and 
only 4 stamens, the fifth posterior stamen being suppressed. 
Some botanists still include the genus Adoxa in this Order,
