16 AN ENUMERATION OF THE BRUNiACE^ [TUtmannia 



distinct species, which differs from the preceding in its more 

 copiously branching habit, shorter, less pilose leaves, and larger 

 flower-heads, which average 2 cm. in diameter. In the Flora the 

 segments of the calyx of B. affinis are stated to be shorter than 

 the petals, but the reverse is the case. Don infers that the 

 flowers of N. globosa are white, but this is erroneous. I am 

 indebted to Dr. O. Juel, of Upsala, for a photograph of Thunberg's 

 specimen of Brunia globosa, which leaves no doubt as to the 

 identity of this plant.
