Layers, which root readily, or seeds. 
Other Species of Ceandthus. — C. ovatus and C. 
intermédius, we have seen, on the authority of 
Torrey and Gray, are only varieties of C. americanus; 
and we have no doubt that this will be the case 
with C. ovalis, C. sanguineus, C. oreganus, and 
other species described by authors. In short, there 4 
appears to us no assignable limits to the sports and 
hybrids that may be produced in this genus. 
275. Ceandthus collinus. 
Orver XXIII. HOMALINA‘CEZ. 
Orv. Cuan. Calyx funnel-shaped, its tube usually adnate to the ovary, its 
limb with 5—15 lobes. Petals inserted into the calyx, as many as its lobes, 
alternate with them, smaller than they, and deemed by some an inner whorl 
of lobes of the calyx. Glands present in front of the segments of the calyx. 
Stamens arising from the base of the petals, either singly, or in threes or 
sixes. Anthers 2-celled, opening longitudinally. Ovary 1-celled, with nu- 
merous ovules. Styles 3—5, simple. Fruit berried or capsular. Seeds 
small. ( Lindl.) — Trees or shrubs ; natives of South America. 
Leaves simple, alternate, with deciduous stipules, sub-evergreen ; toothed 
or entire. Flowers axillary, in spikes, racemes, or panicles. — The species in 
British gardens belong to the genera Aristotélia and Azara (the latter rather 
tender), which are thus contradistinguished : —
