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 

 to be evergreen. Elliottia, Enkianthus, Leucothoe, 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.
