| Hello and welcome to the forum. A few bits of info:
1) It's normal for these bulbs to be somewhat flattened on these hybrids so the flattening isn't cause for concern.
2) The name of the plant is Odontocidium Tiger Crow (no quotes around the last part).
3) Your statement, "and one that is large plump , but soft and rotten" is concerning. This bulb should probably be cut off as this kind of rot can spread fast.
Can you post any pics? It may help us give better advice.
