contenting themselves with a moderate number of specimens, gather them by hundreds, or even by thousands, 
thus imperilling the very existence of species which, like the present, are believed to possess only a very 
restricted habitat. Nor does this recklessness often benefit their employers, for in most cases, the larger the 
consignment, the smaller the chance of its prospering on its way.

the act of flowering.
