Antique Chinese lamp

Looking for any information on what this lamp is; i.e style, period, etc. I read a description regarding Canton rose where one of the styles was referred to as three-color ware. It sounded very similar; i.e. rose pattern on one side and a scene on the other. Characteristics included a raised pattern in green, yellow and aubergine colors. This does describe the lamp somewhat; however, the flower does not look like a rose to me.

Any help or direction would be greatly appreciated. Thanks
