^ Persoon did not describe a species U. microphylla, as usuallj- stated by 

 different authors. He only says in his remarks on U. pumila: "(Sequens quae in 

 horto Celsii coHtur diversa species videtur." According to the quotation " U. 

 pumila, ^ transbaicalensis. Pall. 1. c. fig. A. B. C. E." his variety is to be regarded 

 as typical U. pumila, but he may include, as Pallas did, some other shrubby forms.
