Arth. et Kern, Bull. Torrey Bot. Club, XXXIII, 1906, p. 430. Biol. Weir a. Hubert, , 1917. 203 Spermagonia hypophyllous on 2 —5-year old leaves, abundant, colorless, immersed, almost round, concave in section, subcuticular, 100 — 159/li wide, 85 —110/L/ high, on an average about 127 X 98/j . Aecia hypophyllous on 2 —5-year old leaves, white, cylindrical, — mm across, up to 2 mm high; peridium colorless, brittle, opening at the apex; peridial cells polygonal, vertically elongate, more or less overlapping, 27 —54 X 13—27/u; outer wall smooth, — thick, inner wall rather densely and coarsely warted, 7 —ISjuthick. Aeciospores broad ellipsoid, ovoid, or subgloboid, white, 16—27X 14—21/u (on an average, about 21—23X 17 —18/Li), spore wall densely and rather coarsely warted, colorless, — thick. In some specimens sporelike bodies are frequently found showing small, more or less eccentric recesses and thick walls; apparently, modified peridial cells. Uredia hypophyllous, scattered, pustular, mostly round, — mm across, occasionally elongate, up to 1 mm long; peridium convex, colorless, rather compact, usually opening sideways; peridial cells isodiametrically or irregularly polygonal, obovold, or fusoid, 22 — 70 X 8 —21/Lt (on an average, 40 X 13/u), but greatly varying, averaging in diverse samples 30 —50X 11 —llfji, rounded
