30 11 E. ambiguus Fernald. March 15 (Sunday) Train at 10:00 AM. to New Brunswick. Walked along S. bank of Raritan River. The red sandstone dipping gently to the southwest are cut through by the Raritan R. The low cliffs have an abundance of Pinus virginiana, some P. Strobus and hemlock. Physocarpus opulifolius is common on the sandstones, as Arabis lyrata, Henchera americana, Polypodium vulgare, Diplazium [illegible] and Dryopteris marginalis and D. spinulosa (typical). East of the highway bridge, Hepatica americana and on a little island in the salt marsh, typical Juncus lociustum growing with our trichocarpus? The leaves of this species are very prominent at this time of year; on the other hand of canadense has the bases of the plants dead. Is it an annual? Followed Sanderson Bridge to the golf course, then directly north into the sandy country. Pyxidium there abundant on north slopes of exposed hills. There is also an excellent alder-bearing swamp with a large P. Strobus, plenty of Ilexopis glauca, and probably other pome barkers plants. Continued eastward through the clay pits to South River and by train back to New Brunswick. The first warm day of the year. March 16 (Monday). Continued distribution of duplicata. 17 (Tuesday).
