Clear examples of corms exist in various herbaceous dicotledons [one example:
Cyclamen spp]. Probably many more exist since a corm isn't really very
different from a short rhizome or tuberous stem.
I can think immediately of very few dicots with bulbs [some species of Oxalis
have bulbs, and perhaps also Achimenes [Gesneriaceae] counts (the latter has
small tubers that are mostly fleshy scale leaves].
