(EuNOYMUS JAPONICA, with evergreen shiny leaves is a com- 

 mon front garden shrub. This exotic sp. is not often seen 

 in flower, but it flowered freely at Worthing in the hot 

 summer of 1906). 



N.O. 4. ACERACEM (under Sapindacece, B. 6- H.) 



(91) ACER, L. Black patches on the leaves of either sp. at 

 the end of summer, due to fungus Rhytisma acerinum. 

 In the autumn a sugary material, " honey-dew," 

 appears on the leaves and affords nourishment to 

 swarms of aphides. It is probable that the whole 

 of this honey-dew is excreted by the leaves and not 

 by the plant-lice as Grant Allen thought (note in 

 Lane' sedition of White's Selbourne, 1902), since exuda- 

 tion may take place on uninfested leaves in glasshouses 

 (Nicholson's Gardeners' Dictionary). See Lime. 



330. A. pseudoplatanus, L. (Sycamore), 56. Planted every-

Aesculus pavia, Poir. has red fls., and is much less freq. 

 planted. Seedlings of the white-flowered form are common.
