76 NOTES ON MIMOSE^E. 



Where there were five, the odd one appeared to be placed 

 in front, but of this I am not certain, for owing to the 

 thick texture and obscure venation of the calyx, corolla 

 and staminal tube, I cannot satisfy myself that I traced 

 their relative position very accurately. I had not many flowers 

 to spare for dissection, and in those cases where I made 

 a transverse section in the first instance, they turned out to 

 be only tricarpellary.
