Few, scattered amongst the secidia, pale- yellowish, JEcidiospores. ^cidia rarely on the leaves, hypophyllous, more often on the petioles and stems, densely crowded, caus- ing considerable hypertrophy and curva- ture, between cup-shaped and pustulate, whitish, with a white irregularly torn margin; spores delicately verruculose, yellowish, 15—22 /i. Teleutospores. Sori amphigenous, scattered, minute, roundish, sometimes on the petioles confluent and elongated, long covered by the epidermis, black; spores ellipsoid to obovate-oblong, gener- ally rounded at both ends, not thickened above, hardly constricted, minutely reti- culate, brown, 25—42 x 14—24/x; pedicels hyaline, thin, deciduous. On Car urn (Bunium) Bulhocastanum. Very rare. Dunstable (W. G. Smith). (Fig. 134.) This species has no uredospores. Plowright confused together this and the Puccinia timiida on Conopoditcm denudatum (see his synonymy on pp. 206, 270). The latter species has no aecidia ; this partly explains his remarks that he was unable to obtain any evidence of the connection between the secidium and the Puccinia. Nevertheless, it appears not yet. Fig. 134. P. Bulbocas- tani. Whole plant of C. Bulbocastanujii,with secidia, nat. size. (Dun- stable, April, 1896.).
