They are from one to three rods apart. The Minnesota University here is set in the midst of such an oak opening, and it looks quite artificial; and, unlike our pines left standing, they will probably thrive there as if nothing had happened. Here on the prairie I see the plantain, shepherd’s purse, strawberry, violet sorrel (?), common red sorrel, Ranunculus rhomboideus, Geum triflorum (handsome), phlox (as on Nicollet Island), Druba nemorosa, with black pods, a scouring rush by a slough, low grass, and sedge. But here the prairie is fed over by horses, cows, and pigs. In an open wood north of St. Anthony, Troximon cuspidatum (dandelion-like) out, May 27. The ranunculus going out of bloom; the Geum with yellow petals, the style two inches long. Crossing the bridge into Nicollet Island, find the Zanthoxylum Americanum in flower; the Turritis brachycarpa? or stricta? in bloom,—or perhaps Arabis lævigata; the Hydrophyllum Virginicum, just begun; Phlox divaricata (variety Laphammi) showing raceme not sessile, varying from violet to purple and white; early flowering Lychnis, not out.
