It seems to me that the direction of the torsions in the fruit is of no 

 specific value. The fruits of my specimens have a left-hand screw, and 

 the same is the case in some of the fruits given to me by Mr. Paleski 

 of Tshardshui, while others from the same hand have right-hand screws. 

 According to Borszczow the screw shall be right-hand as he figures is. 

 Many plants (e. g. Atriplex) bear left- and right-hand screws on the same 

 specimen.
