The NH Natural Heritage Bureau has updated the list of rare plants in New Hampshire. Here's a 4-page list of scientific names.

And here's a list that includes common names.

As a result of many hours of work by Sara Cairns, Deb Lievens, and Bill Nichols, we now have a specimen-based county-by-county list of all the vascular plants in New Hampshire (up to date as of April 17, 2019). The checklist lives in an Excel spreadsheet that you can get here: NH county checklist.
The checklist is based on F. C. Seymour’s The Flora of New England (1933) and Ray Angelo and David Boufford’s Atlas of the Flora of New England (2012). The nomenclature follows New England Wild Flower Society’s Flora Novae Angliae (Haines 2011). It is a work in progress; as new plants are discovered and vouchered, they are added to the checklist.
The Consortium of Northeastern Herbaria is making available data and images from thousands of specimens of plants, fungi, diatoms, algae, and lichens. Their portal gives you access to this information. The various herbaria are at different stages in their efforts; the Hodgdon Herbarium at the University of New Hampshire has virtually all its holdings of New England specimens online. Use the portal to look at high-quality images and to search data from the labels.
Use of any specimen data and related material (e.g., images, species checklists, etc.) accessed through this portal requires agreement to the terms and conditions in the CNH data usage policy.

Online list of NH shrubs and lianas
This may be of interest to you, especially if you prefer to use common names rather than scientific names: "Native Shrubs, Subshrubs & Lianas of New Hampshire," published February 2017, by William F. Nichols, State Botanist and Senior Ecologist, N.H. Natural Heritage Bureau, Division of Forests and Lands, Dept. of Resources and Economic Development, and Karen P. Bennett, Extension Forestry Professor and Specialist. Here's a brief description of the list, which indicates rare species.
We list 235 species of native shrubs, subshrubs, and lianas known to occur in New Hampshire. The exact number is tricky to pin down because some shrub species can also occur in tree form. Others are subshrubs, dwarf shrubs or perennial plants that are woody only near the base, where new growth above the base dies back each year. Finally, lianas (woody vine-like plants) are also included in the list.
