New USDA Botanical Watercolors from the 1890s - 1940s
In case any botanical watercolorists are interested - A new archive from the USDA of high resolution scans of botanical art commissioned by the US government's Department of Agriculture from 29 different countries. I'll put a link in the comments in case anyone else finds it interesting. I think you could also find it by searching for, "USDA Pomological Watercolors."

USDA Pomological Watercolors
In 1887 the U.S. Department of Agriculture (USDA) Division of Pomology began hiring artists to render illustrations of fruit varieties for lithographic reproduction in USDA articles, reports, and bulletins. Use of color lithography was critically important to enable the farmer to visualize and comprehend the subjects and principles covered in a particular publication. As a historic botanical resource, this collection documents new fruit and nut varieties, and specimens introduced by USDA plant explorers from the late 19th and early 20th centuries. The collection spans the years 1886 to 1942. The majority of the paintings were created between 1894 and 1916. The plant specimens represented by these artworks originated in 29 countries and 51 states and territories in the U.S. There are 7,497 watercolor paintings, 87 line drawings, and 79 wax models created by approximately 21 artists.
