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].
