Report of the Botanist. 01 



The sori sometimes occupy tlie whole under surface of the leaf. 

 Their black color contrasts beautifully with the light color of the 

 spot. 



PUCOINIA TRTPUSTULATA 71. SJ). 



Spots very small, angular, distinct, yellowish ; sori hypogenous, 

 few, distinct ; spores broadly ovate or sub-triangular, tripustulate, 

 scarcely constricted, brown, t^' long, about y^nnr' ^^ diameter ; 

 pedicel short or obsolete. 



Under surface of leaves of the blackberry, Rubiis villosics. 

 Greig. September. (Plate 3, figs. 14—16.) 



A remarkably distinct species. There are usually from one' to 

 five sori on each spot. There are three prominent points or angles 

 to each spore, one at the apex, two at the base of the spore. To 

 one of the latter points the pedicel is attaclied. The other is 

 sometimes considerably removed from its neighbor, so that it 

 appears to be almost lateral. A little pellucid pustule usually 

 crowns these points, and sometimes two may be seen on the apical 

 prominence. 



PUCCINIA MINUTULA U. SJ). 



Spots suborbicular, scattered or confluent, yellow, with a purple 

 or brown center ; sori situated on the center of the spot, very 

 small, crowded, black, covered by the epidermis ; spores oblong, 

 acute or acuminate, rarely obtuse, slightly constricted, -s^'-xhr' 

 long ; pedicel generally shorter than the spore. 



Under surface of leaves of Solidago altissinia. Catskill moun- 

 tains. July. 



The sori under a lens look like some small Sphseria. Allied to 

 P. virgaurecB. 



Puccini A Gekardii n. sp. 



Spots orbicular, distinct or sub-confluent, yellow, depressed 

 above, bullate below ; sori crowded, matted together, or confluent, 

 tawny or amber-brown ; spores oblong-clavate, distinctly constric- 

 ted, obtuse, 'ri^' long, pedicel nearly as long as the spore. 



Under surface of leaves of Aster simjplex. Poughkeepsie. 

 Gerard. Green bush. July. 



The difierent color and matted appearance of the sori separate 

 this species from P. Asteris Schw.. Sometimes the sori are quite 

 plentiful on the superior surface of the leaf.
