species, to which evidently Plowright's specimen may be ascribed. Cooke's 

 figure of his U. apiculosa, on Trifolium repens (Micr. Fung. pi. vii. f. 154), 

 is probably the same species.

[Spermogones 



uEcidiospoi^es 



Uredospores. 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 /x ; 

 epispore lh, — 2 /x thick, with 4 — 6 or even more germ-pores, 

 each with a small hyaline cap. 



Fi^\ 45. U. striatus. a, two teleutospores on T. minus (ex herb. Broome); 

 b, a teleutospore on T. arvense (foreign, ex herb. De Thiimen); c, uredo- 

 spoi'e 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, 18 — 24 x 15 — 

 20 /z; epispore 1^ — 2/i thick; pedicels short, hyaline, deciduous. 



[iEcidia on Euphorbia Cyparissias, 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 tecidial stage under U. Pisi. Schroter 

 proved the connection of an secidium on Euphorbia Cyparissias with an 

 exactly similar Uromyces on Trifolium agrarium. U. striatus is found 

 elsewhere on Trifolium procumbent and also on many species of Medicago,
