$ Pasce Ix a species U. microphylla, as usually stated by 
different, authors. He only says in his remarks on U. pumila: "Sequens quae in 
horto Celsii colitur diversa species videtur.” According to the quotation “U. 
Pumila, 8 transbaicalensis. Pall.l.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.
