ßlDGOOD, John, Disease of the leaves oi Calanthes. 

 (Journal of the Royal Horticultural Society. Vol. XXIX. 

 Dec. 1904. p. 124—127.) 



The leaves of various species of Calanthes are frequently disfigured 

 by patches of black and dead tissue. There is no trace of fungus 

 present. 



The author has had the disease under Observation for three years. 

 He states that the general practice is to give Calanthes too much sun- 

 light, a shaded position should always be chosen as the Calanthes leaf 

 shows an extreme type of hygrophilous structure. Insoluble indigo is 

 found present in the diseased portions and the writer regards it as pro- 

 bable that faulty treatment (e. g. as to sunlight, manure etc.) causes the 

 lowering of the cell vitality and this may bring about the decomposition 

 of indican and the precipitation of indigo. He suggests that the pro- 

 duction of indigo may be the cause as well as an effect of the death of 

 the cell. A. D. Cotton (Kew).
