record of a few of these is imw given. 



On June 2j, a plant was arranged so that tin- cotyledo- 



nary shoot was above -round. The shoot was short and 

 white. 



On July 8, the cotyledonary shoot was quite green, and 

 was about six inches long. It had branched, and was 

 growing out in a horizontal direction. It was turned up 

 and tied to a stick. 



On July 15, the shoot was about twelve inches long, pos-

 stem, but no twining had taken place. 



On June 27, a plant was found having the cotyledonarv

On July 15, the plant was eighteen inches high, the

On July 22, no twining had occurred. 



About this time, a plant having four cotyledonary shoots 

 above ground was noticed. It was observed again early in 

 September. Extensive growth had taken place, but no
