In the original description of Cooke and Massee only teleutospores are 

 recorded, but uredospores were also obtained from the original material 

 labelled in Cooke's handwriting. 



Sometimes there are abnormal elongated teleutospores up to 60 JJL long. 



Several bicellular spores were met with similarly coloured to the normal 

 teleutospores, constricted at septum, irregularly warted, with prominent 

 hyaline apiculus, 59 x 28 p.

Thelymitra. 



8. Uromyces thelymitrae McAlp. 



Sori on leaf and sheath, scattered or gregarious, bullate, ellipsoid, 

 yellowish to brownish, compact, surrounded or almost covered by 

 ruptured epidermis, except for a narrow slit, up to 1 J mm. long. 



II. Uredospores ellipsoid to obovate or pear-shaped, golden-yellow, 



echinulate, with as many as four equatorial germ-pores, 25-32 X 

 18-21 p. 



III. Teleutospores ellipsoid to oblong, or polygonal, chestnut-brown, 

 relatively thick-walled, irregularly knobby, with hyaline apiculus 

 35-45 x 25-30 p, average 36 x 26 p pedicel hyaline, short, 

 deciduous, up to 1 1 p broad adjoining spore.

 An aecidial stage has been found in Java, by Raciborski, on Thelymitra 

 javanica Blame, but it has probably no connexion with our native species.
