Uromyces Legmninosae. 



This rust has not been found in Victoria, and although it is said to 

 very common in New South Wales, on applying to Dr. Cobb for specimens, 

 he informed me that they had all been destroyed by insects. Only the 

 uredo-stage was found in New South Wales, and the exact species is still 



doubtful.

Sori amphigenous, solitary or in groups and then confluent, elliptic to* 

 discoid, dark-brown or black, erumpent and girt by the ruptured 

 epidermis. 



II. Uredospores golden-brown, fusiform, obtusely warted, with acute 



and more or less hyaline apiculus, 3-4 equatorial germ-pores on 

 one face, 57-77 x 17-25 p, average 62 x 23 p. 



III. Teleutospores intermixed with uredospores, ruddy brown, globose 

 to depressed globose, epispore rather thin, scarcely 2 p thick,, 

 somewhat polygonal seen from above and then germ-pore very 

 prominent, 25-30 p diam. or 16-21 X 25-35 //, average 18 x 28 p ; 

 pedicels deciduous, hyaline, elongated, up to 96 p long, with/ 

 septum at a short distance beneath spore.

Portion of the original material named in Cooke's handwriting is in the 

 National Herbarium, and our description is based upon that. In the original 

 description by Cooke and Massee the uredospores were unfortunately mis- 

 taken for teleutospores and vice versa. The uredospores are easily known 

 from being obtusely warted and with equatorial germ-pores, apart altogether 

 from size and shape. 



The teleutospore is solitary at the apex of the pedicel, but the sep- 

 tum at a short distance from the spore foreshadows the Uromycladium wil 

 a colourless vesicle or cyst produced laterally immediately beneath septum. 



The nature of the teleutospore and the presence of a septum in the stall 

 was so suggestive of Uromycladium that the material was specially ex- 

 amined to see if more than one spore was borne on a stalk, but the most 

 careful search failed to reveal any indications that this was the case.

Hardenbergia^ 



Sori on under surface of leaf, brown, crowded, globose to ellipsoid, often 

 confluent, bullate, with ruptured epidermis, which usually remains. 

 in large patches.
