OLEACEAE. 



PHILLYRAEA. 

 (Family Oleaceae). 



Shrubs or small trees: ever- 

 green. Twigs rather slender, 4- 

 lined from the nodes: pith round- 

 ish, small, continuous. Buds 

 small, sessile, superposed, com- 

 pressed-ovoid, with 1-3 pairs of 

 scales, the end-bud frequently 

 lacking. Leaf - scars opposite, 

 raised, crescent-shaped: bundle- 

 trace 1: stipule-scars lacking. 

 Leaves petioled, dotted beneath. 



Loefling, in his essay on Gem- 

 mae Arborum, 191, 197, noted in 

 1749 that PUillyrea appears to 

 have two terminal buds. This re- 

 sults, as with the lilac, from the 

 absence of a true terminal bud, 

 the branching of the next year re- 

 sulting from the development of 

 the uppermost pair of axillary 

 buds. 



1. Exposed bud-scales 2, valvate. 2. 

 Exposed scales 4 or 6: leaves lanceolate. 



(1). P. angustifolia. 



2. Buds and twigs pubescent: leaves small, toothed. 



(2). P. media. 

 Glabrous: leaves larger (8-10 cm.), entire. (3). P. decora.
