 very veiny, the veins depressed above and very con-

 appearance to the 

 whole. The tubular 

 florets are white, of a 

 greenish cast, the sta- 

 men tubes dark pur- 

 ple, the protruding 

 styles pure white, and 

 the enveloping in- 

 volucre green, the out- 

 come a dull greenish 

 white.
