whether sub-epidermal or sub-cuticular ; (2) the number and 

 position of the germ spores of the uredo-spores ; and (3) the 

 position and number of the cysts. In his opinion R. mexicana, 

 R. mim.osae-sensitivae and R. inconspicua are all one and the 

 same species. Four other species [he continues] are so closely 

 related that they should be considered as one species, viz.: R. 

 expansa Diet. & Holw., R. fragrans Long, R. humphreyana P. 

 Henn. and R. pulcherrima Arthur.

Mr. Elam Bartholomew distributed this installment of his

 being those of Puccinia, over a dozen ; and Uromyces, little less 

 than a dozen.
