It was not long ago that when we saw the enormity of including Xanthorrhoea among bulbs, several members took it hilariously saying we were taking ourselves too seriously by objecting to that. So it seems the scope is vague and foggy enough to treat all sorts of plants as bulbs these days. I consider this plainly giving false and misleading information to beginners that in good faith rely to PBs as the fabulous source of knowledge it has been.
