S. Sullivant (q.v.): *Musci boreali-americana*... *exsiccata*. Fossil collections, see Darrah (1934, 1942), mainly at the Botanical Museum, Harvard; some later material also at [[Collection US|US]]. Many Lesquereux type specimens of mosses are in the Sullivant and James collections at [[Collection FH|FH]], which also holds bryophytes collected by L. himself. Many letters by L. are at Harvard University. The corrrespondence with Thomas Potts James (270 letters) and the manuscript of the *Manual of mosses* are at [[Collection FH|FH]]. #### Bibliography and biography Andrews p. 294-295; Backer p. 325; Barnhart 2: 372; BJI 1: 37; BM 3: 1094-1095; Bossert p. 235; CSP 3: 970, 8: 208-209, 10: 570-571, 12: 442-443, 16: 735; DAB (by G.
