The new species may be characterized as follows : 



Gymnosporangium multiporum sp. nov. 



Teliis inter folia squamosa erumpentibus, irregulariter dis- 

 positis, musciformibus, parvis, 0.5-0.8 mm. altis, pallide castaneo- 

 brunneis ; teliosporis uniseptatis, ellipsoideis, 20-24 i"- X 45-5 1 

 apice et basi rotundatis, medio constrictis ; episporio cinnamomeo- 

 brunneo, 1.5-2.5 mm. crasso ; pedicello hyalino, 7-9^ diam., 

 longissimo; poris germinationis 5-7. sparsis instructis. 



In ramulis Sabinae monospermae (Engelm.) Rydb. (Juniperi 

 occidentalis monospermae Engelm.) Trinidad, Colorado, Maio 

 20, 1908, Frank D. Kern. 



In addition to the type collection the writer has received a 

 specimen from Prof. E. Bethel on Sabina utahensis (Engelm.) 

 Rydb. (Juniperus calif ornica utahensis Engelm.), collected at 

 McCoy, Colo., July 16, 1908. These two localities are rather 

 widely separated but may be taken to indicate that the species 

 is* distributed all over the southern and southwestern portion of 

 the state. The fact that both Sabina monosperma and S. 

 utahensis are hosts is an indication of the similarity between 

 these two cedars. Gymnosporangium speciosum also occurs on 

 these two hosts and there is every reason to suppose that a 

 parasite inhabiting one may inhabit the other. No clue as to a 

 possible roestelial connection has yet been obtained either for the 

 new species or for G. speciosum.
