ERICACEAE, 
ZENOBIA. 
(Family Ericaceae). 
Shrubs: deciduous. Twigs slen- 
der, roundish: pith small, more 
or less 3-sided, continuous but 
with firmer strands here and 
there. Buds solitary, sessile, 
small, conical or somewhat 2- 
edged and pointed becoming glo- 
bose and blunt, with 2 or 3 ex- 
posed scales. Leaf-scars minute, 
somewhat raised, rather 3-sided: 
bundle-trace 1: stipule-scars lack- 
ing. If fruit is present it con- 
sists of small depressed-globose 5- 
celled capsules. 
Like the Rosaceae, the family 
Ericaceae comprises a number of 
genera which are readily separa- 
ble on the technical characters af- 
forded by flowers and fruit, but: 
do not present readily seized win- 
ter-differences unless they chance 
Elliottia, Enkianthus, Leucothde, Lyonia, 
Menziesia, Oxydendrum, Pieris and Zenobia are certain to 
afford puzzles: but the fact that they are ericaceous will be- 
come the more evident because of this. 
Glabrous: twigs reddish becoming buff, smooth. 
Z. pulverulenta.
