OLEACEAE 281 



Insect white wax is produced on Fraxinus chinensis and F. mariesii. 

 The insect, Coccus pe-la, is bred on the Ligustrum lucidum and other 

 species of privet. In April, the mature cocoons are carried by night 

 some distance to the region where the ash trees are cultivated and there 

 affixed to the branches. In August, the branches incrusted with the 

 wax are removed and boiled, the wax thus separated is melted and 

 allowed to harden in pans. Pe-la is used for coating candles made from 

 vegetable tallow and to a smaller extent from animal tallow, for coating 

 pills and also for imparting a glossy surface to silks and better grades of 

 cloth.

 short acuminate, serrate, glabrous, to 4 cm. long, distinctly stalked. 

 Flowers in terminal panicles many flowered, to 6 cm. long; corolla 

 divided nearly to the base; calyx with narrow acute lobes; filaments

Fraxinus mandschurica Ruprecht. 



Tree, 30 m. tall. Branchlet glabrous, quadrangular, with dark brown 

 buds. Leaf rachis winged and brownish tomentose at the base of the
