Symplocos schikdeana Schlecht. Linnaea 8: 527. 183;i. Tyi^e collected be-

138. OLEACEAE. Olive Family. 



Shrubs or trees, rarely herbs, unarmed; leaves all or mostly 4ii>posite, sim-

 Olea europaea L., which was introduced into Mexico soon after the Conquest, 

 but is only sparingly cultivated. The lilac ("lila"), Syringa vulgaris L., is 

 •frequently found in Mexican gardens. Several species of jasmine (Jasminum) , 

 an Old World genus, are widely cultivated in Mexico, where they are known 

 as " jazmin " (often with varietal names) and "Gran Duque."
