Mr. Eyles says in regard to his specimen No. 1235: “ In December, 1917, I planted 
here several of the seeds of No. 1235 (over fourteen years old) after soaking forty-three 
hours in water. Germination was 100 per cent., and one of the plants has been growing 
since. Itis about 12-15 ft. high, and in March it was profusely covered with medium- 
sized yellow flowers which never opened until 4.30 p.m. daily.”
