एषा this lady, राक्षस्यः at the shedemons, न पश्यति she is not looking, इमान् these, पुष्पफलद्रुमान् trees full of flowers and fruits, न not seeing, एकस्थहृदया with singleminded attention, राममेव only Rama, अनुपश्यति thinking, नूनम् surely.

She is looking at neither the shedemons nor these trees full of flowers and fruits. She is surely thinking of Rama with a singleminded attention.
