Sori amphigenous, scarcely ever on the nerves, w^ithout spots, scattered, occasionally aggregated and confluent, minute, pulverulent, cinnamon; spores globose to ellipsoid, faintly and sparsely echinulate, yellowish-brown, 15â22 fi; epispore 1^â2 /a thick, with 4â6 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 on T. avvense (foreign, ex herb. De Thiimen); c, uredo- spore from the 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, 18â24 x 15â 20 yu.; epispore 1-|-â2 /jl thick; pedicels short, hyaline, deciduous. [iEcidia 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. JulyâAugust. (Fig. 45.) See remarks made about the secidial stage under U. Pisi. Schroter proved the connection of an secidium on Euphorbia Gyparissias with an exactly similar Uromyces on Trifolimn agrarium. U. striatus is found elsewhere on Trifolium procumbens and also on many species of Medicago,. Please note that these images are extracted from scanned page im
