on Salix repens at Tiptree Heath, which is in all pro- 

 bability this species. The species of Melampsova have 

 for their ascidioform the species of CcBoma, and it has 

 been proved by culture experiments that the species 

 occurring on Salix repens is connected with Caoma 

 orchidis Alb. and Schw. (q.v,). 



It is described and records of the culture experiments 

 are given b}' Dr. Plowright in Card. CJiroii. 8, 1890, p. 

 41 ; Journ. Roy. Hort. Soc. 12, 1890, p. cix. ; and Zeitschs. 

 f. Pflanzenhvanhli i, 1891, p. 131. A full account of 

 the relationship of these two genera is given by Klebahn 

 in Die imrtsii>echselnden Rostpilze, 1904, pp. 396-426.
