Uromyces Sapindaceae. lot 



cells firmly united, thickened all round but thicker on one side, 

 striated, individually somewhat lozenge-shaped, collectively elon- 

 gated polygonal. 



Aecidiospores angular, globose or oblong, orange-yellow, 

 smooth, 18-28 x 16-22 /<. 



II. Uredosori cinnamon or chestnut-brown, scattered or circinate, 



small, surrounded by the ruptured epidermis. 



Uredospores sub-globose, elliptic or ovoid, yellowish-brown, 

 echinulate, with two distinct equatorial germ-pores on one face, 

 25-32 x 16-25 /*, average 28 x 21 //. 



III. Teleutosori dark-brown, margined by the ruptured cuticle, 

 scattered or orbicularly arranged. 



Teleutospores ovate or ellipsoid with a colourless papilla at 

 apex, dark -brown, smooth, 26-35 x 19-25 jj, average 32 x 21^; 

 pedicels thin, rather long, soon deciduous. 



On leaves of Beta vulgaris L. Beet and Mangel. 



Victoria This rust generally occurs wherever beet or mangels are 

 cultivated, and has been found at Port Fairy, Maffra, Murtoa, 

 Minyip, Ballarat, etc. It also occurs throughout the year 

 from Jan. and Feb. to Nov. and Dec. As early as 1878 this 

 rust from Ballarat was determined by Thuemen 2 .

The teleutospores are rather scarce, but they were found at Port Faiiy 

 in August and measured 27-33 x 22-24 //. 



The aecidiospores were found towards the latter end of August and up 

 to December on young leaves of beet growing from roots left in the ground 

 during the winter. According to Plowright they very rarely occur in 

 Britain in a state of nature. They were found to germinate very freely in 

 water.
