To "bulb" or not to "bulb"?

"what about Wyethia (mule ears, Asteraceae), or Aquilegia (columbine, 
Ranunculaceae)?" -Nathan

I don't know about Frasera, but these two are fibrous rooted while Cynoglossum grande has a proportionally large woody taproot that can be dug and handles like a bulb, just not left to dry out (unlike Echinacea angustifolia, for example). Even young non-flowering plants have roots that look way too big for them. I have a picture, I'll post it up soon. Taproots are certainly geophytes, if you define a Geophyte as an "underground storage organ", to the exclusion of fibrous roots.

Not to say we should "ban fibrous roots", but we probably have a vary small (if any) number of genera that possess fibrous roots. Perhaps the grass tree?

I do see what you mean, many perennial's are shipped bare root, thus may be considered to be "handled like bulbs". I think this is where the good judgment part of our policy comes into play. Like Nhu said, very few people actively contribute to the wiki, so do not fear that we will be overrun by herbaceous perennials.

When I decided to add the two genera in the Boraginaceae, I first read the "What is a Bulb?" page to see what our guidelines were. Then, I ran it by the administrators to see if I understood correctly. They were all understanding, and a few encouraging of what I wanted to do. So I went ahead with it.

I encourage everyone to read the new pages. Symphytum certainly belongs here, as some species do possess tubers (pictures coming soon).
