which Endlicher happened to examine were pentapetalous, 
which is not the more usual case; and he erroneously states 
the plant to form a large tree, whereas it is commonly a slen- 
der shrub, of five or ten feet in height, or at most a small 
tree. Misled by these discrepancies, and by the differences 
of the two kinds of flowers, and, it would seem from his 
description, happening to possess fetrasepalous as well as 
tetrapetalous flowers (although there are five sepals in all 
my Lindheimerian and other specimens,) Mr. Scheele has 
wrongly introduced a second species, under the name of U. 
heterophylla. The leaflets vary from five, or even three, on 
the earlier leaves, to seven." Gen. Jil. l. c. —In seedling 
plants, raised in the Cambridge Botanic Garden, I have 
noticed a lusus of the earliest leaves, in which the leaflets 
are confluent.
