In the above description, as well as the figures, some 
allowance must be made for the extreme minuteness of the 
flowers and fruit, and for the few individuals at my dis- 
posal for dissection. There was an appearance in the seeds 
of the hilum being at the upper extremity, as if the seeds 
were suspended; but such is not the case in the fruits of 
Celastrinee. I trust at some future time to obtain more 
copious specimens, and to determine more exactly the struc- 
ture of the fruit and seeds, and to be able then to give an 
account of the female flowers, which at present are unknown 
to me,
