(Orig.) 336 Uredia hypophyllous, at first single and rather large, later small, scattered over entire frond, 1 —2 mm, causing appearance of yellowish patches on the upper side of the leaf. Urediospores ovoid, globoid, or angular, 14—21X13 —15m; walls 2.0—2.5//thick, sparingly verrucose (at intervals of2.0—2.5^); a conspicuous thin spot on the wall probably indicates site of pore.

In some species many of the other cells also contain pits with a thin membrane across the open- ing and these presumably facihtate the diffusion of food materials. Most of the genera possess systems of anastomosing mucilage ducts. In L. cloustoni
