112 ROSACEAE. 
RHODOTYPOS. 
(Family Rosaceae). 
Spreading rather low shrubs: 
deciduous. Twigs round, moder- 
ate: pith moderate, round, con- 
tinuous, white. Buds moderate, 
becoming collaterally branched 
and at length very slightly stalked, 
ovoid, with some half-dozen pairs 
of glabrate exposed scales. Leaf- 
scars opposite, crescent-shaped or 
somewhat 3-sided, moderately 
small, somewhat raised, ciliate at 
cop like the line by which they 
are connected: bundle-traces 3: 
stipule-scars lacking. 
The opposite leaves of Rhodo- 
typos present a rare exception to 
the general rule that the leaves 
of Rosaceae are alternate, which 
to a novice is one of the easily 
learned characters by which 
woody Rosaceae may be dis- 
tinguished at a glance from woody Saxifragaceae, to whicn 
they bear a close resemblance sometimes. 
From a study of the vascular arrangement in multiple 
buds, Baldacci and Filipucci have shown in the second vol- 
ume of the Bulletin of the Boissier Herbarium that in Rho- 
dotypos, aS in Coriaria. and many other cases, the supernu- 
merary buds are derivatives of the normal axillary bud and 
not independent structures. 
Winter-characters are figured by Schneider, f. 137. 
Twigs olive-brown, glabrate. R. Kerrioides.
