Total Overhaul Mod List Error - Missing Mesh Files

I appear to be missing these mesh files from the total overhaul:

flora_bc_fern_02.nif

flora_bc_fern_03.nif

flora_bc_grass_01.nif

flora_bc_lilypad_01.nif

flora_bc_lilypad_02.nif

pc_flora_reedgrp_01.nif

flora_reedgrp_02.nif

flora_kelp_03.nif

flora_kelp_04.nif

flora_bc_lilypad_03.nif

flora_kelp_01.nif

flora_kelp_02.nif

flora_grass_01.nif

flora_grass_02.nif

flora_grass_03.nif

flora_grass_04.nif

flora_bc_fern_04.nif

in_cave_plant00.nif

Does anyone know which mod these would come or how I can just download these separately?
