GUELDER ROSE. 279 



lobes^into which the three principal parts of the 

 leaf are divided. The whole of the leaf surface, 

 thus intersected by the principal lines of the 

 venation, is traversed by veinlets which form 

 irregular- shaped figures. On the tissue and 

 within the framework thus, so to speak, formed, a 

 fine and elaborate network of still smaller veinlets 

 is spread. 



It is not so much by the variation of tints that 

 the Guelder Eose is distinguished in the Autumn 

 as by the magnificence of its hue of empurpled 

 crimson. The deep green leaf oftentimes, on the 

 wane of summer, assumes a darker green tint 

 than it had shown before. Upon this a hue of 

 red begins to appear and, deepening, suffuses the 

 whole leaf. Sometimes one and sometimes two 

 of its lobes may be first affected, whilst the other 

 lobes on the same leaf are green. But the colour 

 soon spreads and, in a very short time from its 

 original appearance, the entire leaf becomes a 

 glowing crimson or purple or purplish crimson ; 

 or leaves may be found with purplish crimson 

 centres and golden margins, or gold, purplish 

 crimson and green may be found intermingled
