Tubeuf del.; specimen from Herr Schnabl of Munich.) Bj Urocystis Leimbachii {U. aneviones), causing swelling at base of stem of Adonis aestivalis, (v. Tubeuf del.; Bpecunen from Pi-of. Stahl of Jena.) U. violae (Sow.). (Britain and America.) The deforma- tions induced by this brand are not uncommon on Viola odorata in gardens, also on V. tricolor, V. hadensis, and V. hirta. Its presence is shown externally by the marked thick- ening and malformation of leaf-petioles, runners, leaves, and fruit-stalks (-Fig. 174). The swellings extend round the whole stem, and form pustular outgrowths on the leaves ; the black spore-masses appear after rupture of the epidermis. The flower may develop normally although other organs are diseased. In a case from the garden of Prof. Hartig, a flower-bud unfolded prematurely in the autumn, its stalk was very much deformed, the flower itself was somewhat stunted, yet.
