Puccinia Ipomaeae panduranae (Schw.) Syd. in H. et P. Sydow: 

 Monograph. Ured. 1 Puccinia p. 323. 



Under Albugo Ipomaeae panduranae (Schw.) Sw. — vide supra — 

 we have already had occasion to mention this species and to make some 

 remarks on it. The specimens examined are collected upon Ipotnaea 

 triloba, Ip. sp. and Quamoclit coccinea and contain nothing but aecidia. 

 On Ipomaea these agree perfectly with the description by H. et P. Sydow 

 1. c, while the form on Quamoclit has less developed nearly plate-shaped 

 pseudoperidia and more pulverulent contents. The species-identity of the 

 two forms however is doubtless, as rather typical aecidia sometimes occur 

 also on Quamoclit and as the microscopic characters agree exactly in the 

 two forms.

With the uredo-stage of the above-named African species our Leo- 

 notis-uredo agrees as well macro- as microscopically and is surely iden- 

 tical with it. Teleutospores (which according to Hennings are very 

 scarce on the African specimens) were not to be found.
