Sherardia arvensis. 
So much has been said of this plant in the BULLETIN, that I 
am moved to call attention to some facts in its life-history that 
merit attention. I suppose in the work of most botanists’ lives, 
there is a large amount of “ unfinished business,’ which we hope 
to take up and consider, but which, as years roll over us, we feel 
may never be reached. Long ago I had hoped to take up a fur- 
ther study of Sherardia. As the time may never come, I throw 
out what I have noted for others to build on if they feel so disposed. 
I have looked for dimorphism, common in allied genera, and 
at one time thought I had detected it. But the pistil grows af- 
ter the stamens have reached their final length. This explains 
why the pistil seems sometimes equal and sometimes longer than 
the stamens. 
_ The stamens have a curious fashion of recurving at the an- 
gles of the corolla-tubes the day after the anthers mature, but 
they assume an erect position the following day. 
The seeds are very small, but the cotyledons or seed-leaves 
are remarkably large. I have sometimes seen them half an inch | 
in diameter. In poor soil they are a quarter of aninch. The 
succeeding nodes have leaves four in a whorl, and these four are 
also large, orbicular and abruptly pointed. —
