Hi Maryanne - your image is not very clear alas - so I can only guess - I am thinking you might have something in the Acanthaceae, Justicia carnea "possibly" . I judge this by the venation and the pinkish colour on the leaf underside. But its only a wild guess - as a rule for sterile material one needs clearer images showing both leaf surface details, leaf shape, stem and leaf/stem junction (just case there are stipules) etc.
