My wife has owned this plant for at least 5 years, probably longer, it has never had expert care, but has always done ok, but itbhas been slowly deteriorating over the past 6 months.I have googled some photos and In think it couls be a variety of Syngonium, but I'm not sure.It lives about 10 feet away from a west facing window and in an attempt to help the plant my wife repotted the plant into a bigger pot about 6 weeks ago, it has got worse since then.There are 3 very sick leaves remaining.Please help identify the plant and what we can do to save it.Thanks
