After consulting with the math professor who is from Turkey at my university, it seems that Cigdem is a botanical name, referring to a specific plant which is part of the onion family, though not necessarily the plant which grows our edible onions. :)
And my guess from finding this Turkish site through Google is that the "cigdem" flower is related to the crocus:
