SAXIFRAGACEAE. tit 
DEUTZIA. 
(Family Saxifragaceae). 
Usually small and _ slender- 
branched shrubs with exfoliating 
bark: deciduous as to our species. 
Twigs round, often stellate-pubes- 
cent, usually fioriferous or dying 
back at the end: pith moderate, 
round, pale and spongy or brown 
and excavated between the nodes. 
Buds. solitary or _ collaterally 
branching, nearly sessile, com- 
pressed-ovoid or triangular-oblong, 
with 2-6 pairs of exposed scales. 
Leaf-scars opposite or exceptional- 
ly whorled, triangular or trans- 
versely elongated, slightly raised, 
connected by transverse ridges: | 
bundle-traces 3: stipule-scars lack- 
ing. 
Though the deutzias are some- 
what difficult to name by ordi- 
nary characters except when in 
flower, the species most commonly seen differ rather markedly 
in pith and bud, so that they are quite as readily known in 
winter as at other seasons.—References under Schizophragma.
