As already noticed, the sporogenous cushions are generally formed on one side. After Fig. 229.—Two sections from a swelling on a Juniper-bi-anch. a. From the middle of the swelling ; the rind under the spore-cushion is much thickened, and the wood is much broken up by tnicts of parenchyma. 6, Section from 2 cm. under a ; abnormal development of parenchyma in the wood has begun in the outer year-rings. (After Woernle.) the shedding of the cushion, a corky layer arises in the paren- chyma undcrnoatli it, and so a bark-scale is produced. Gymnosporangium sabinae (Dicks.). (Britain.) The mycel- ium hibernates chietiy in Ji'Jiijyerus Sahiiia (Savin), and induces swellings on the twigs. It also occurs on Jun. Oxyccdrus, ' I found this host-species near Fiunie.
