Sori amphigenous, scarcely ever on the nerves, without spots, scattered, occasionally aggregated and confluent, minute, pulverulent, cinnamon; spores globose to ellipsoid, faintly and sparsely echinulate, yellowish-brown, 15—'22 fi; epispore 1^—2 /x thick, with 4—6 or' even more germ-pores, each with a small hyaline Fig. 45. U. striatus. a, two teleutospores on T. minus (ex herb. Broome); b, a teleutospore ou T. arvense (foreign, ex herb. De Thiimen); c, uredo- spore from tlie same leaf as a. Teleutospores. Sori similar, but darker; spores globose to ovate, with a minute and narrow papilla, striated from apex to base by longer or shorter lines of warts, brown, 18—24 x 15— 20yu,; epispore 1|-—2/x thick; pedicels short, hyaline, deciduous. [^cidia on Euphorbia Gyparissias, not known in Britain;] uredo- and teleutospores on leaves and stems of Trifolium minus. Bath (Herb. Broome); King's Norton (Worcestershire). Very uncommon. July—August. (Fig. 45.) See remarks made about the a3cidial stage under U. Pisi. Schroter proved the connection of an secidium on Euphorbia (Jyparissias with an exactly similar Uromyces on Trifoliuin agrarium. U. striatus is found elsewhere on Trifolium procwnhens and also on many species of Medicago,. Please note that these images are extracted from scanned page images that may hav
