Bean Anthracnose 153 



specific name nanus, however, refers to the bush forms of P. vulgaris, 

 and the name compressus to another classification of varieties now included 

 in P. vulgaris. 



The writer has reported (Barrus, 1918:610) some good infections from 

 inoculations made at various times during several years on the leaves of 

 a number of varieties, both pole and dwarf, of Phaseolus lunatus L., both 

 the small, or sieva, lima and the large lima. Fair infections were obtained 

 on the stems, and also, from field inoculations, fair to good infections on 

 the pods (fig. 15). From inoculations made at various times, the varieties 

 Scarlet Runner and White Dutch Runner, of P. multiflorus Willd., have 

 shown slight to fair infection on leaves and pods; the latter variety especially 

 showed fair infections on pods (fig. 16) and seeds. The tepary bean, 

 P. acutifolius var. latifolius G. F. Freeman, has always become badly 

 affected when inoculated in the seedling stage. 



The article just cited reports also the results of inoculations made on 

 from one to several varieties of a number of species of Phaseolus supplied 

 by E. V. Piper, of the United States Department of Agriculture. Slight 

 infection was obtained on Phaseolus aureus Roxb., but on P. aconitifolius 

 Jacq., P. annularis (Willd.) W. F. Wight, P. calcaratus Roxb., P. mungo 

 L., P. semierectus L., and P. sublobatus, no definite infection resulted. 



Susceptibility of plants of other genera and families to infection 



Frank (1883 b: 518) obtained no infection on cucumbers which he inoc- 

 ulated with anthracnose. Scribner (1888:362) states that the fungus 

 attacks watermelon rinds as well as beans. Farlow and Seymour (1888) 

 and Saccardo (1898: 316) record it as occurring on Citrullus vulgaris Schrad. 

 Galloway (1889) ascribes the disease "melon rust" to Gloeosporium 

 lindemuthianum Sacc. & Magn. Halsted (1893 b: 327, 329) obtained 

 infection, from beans, on detached fruits of eggplant, pear, citron, pepper, 

 and persimmon, and he believes (page 333 of reference cited) that the three 

 solanaceous plants, tomato, eggplant, and pepper, are preyed upon by 

 the same Colletotrichum lindemuthianum which causes a pod spot of the 

 bean. Stoneman (1898:93) points out that inoculations made on detached 

 fruits placed under a bell jar cannot be depended on, as such fruits are 

 much less resistant to attack than are fruits under normal conditions, 

 and are more in the nature of culture media. Smith (1904:28) obtained 

 good infection from inoculations made on bean, but none on cucumber,
