UROMYCES 



/Eddiospores. .Kcidia amphigenous, clustered in circles 5 — 

 l<» mm. diam., cylindrical, whitish, margin deeply torn; spores 

 delicately verruculose, yellow, L8 — 22 /x diam. 



Uredospores. Sori amphigenous, scattered or gregarious, 

 round or more frequently elongate, small, 

 surrounded by the conspicuous torn epi- 

 dermis, cinnamon; spores globose to oval 

 or oblong, delicately and sparingly echinu- 

 late, yellowish-brown, L8 — _•"> x 1(5 — 21 /x: 

 epispore about 1 \ fx thick. 



Teleutospores. Sori amphigenous but 

 mostly cauline, on the leaves rounded and 

 1 — 3 mm. diam.. on the stems lanceolate 

 and even as much as 3 cm. long (Sydow ), 

 thick, compact, dark-brown; spores vei \ 

 variable, oval to subpyriform, rounded 

 or subcorneal at the apex, thickened or 

 not, smooth, brown, 24 — 35x18 — 20//,; 

 pedicels pale-brown, persistent, up to 80 /x 

 long or more.

Teleutospores on 

 Suaeda fruticosa 



(foreign, ex herb. De 

 Thiimenl. 



On stems, branches and leaves of 

 Suaeda maritime/,. Rare. Terrington 

 Marsh (Mr H. G. Ward); North Wootton Marsh (C. B. P.); 

 August. The gecidia are recorded from Worthing (Miss A. L. 

 Smith, Journ. of Bot. May, 1898), as well as by Plowright from 

 North Wootton. (Fig. 04.) 



Teleutospores very variable, short and broad or long and narrow in 

 the same sorus ; thickening of apex also varying from 3 to 7 /* ; pedicels 

 often very long and flexuous. 



The name of this species is misleading ; it has been found on S. 



fruticosa, but not on the present-day Chenopodium. Plowright mentions, as 



showing the distinctness of this species from U. Salicomiae, that at North 



Wootton Marsh it did not spread to Salicomia herbacea, which was 



Distribution : Germany, and most of the countries in South 

 Europe and North Africa.
