in the State of Wyoming is profitable, and that an excellent quality 

 of vegetable ma}^ be produced. The partial failure of this crop in 

 1906 probably caused a loss of some hundreds of thousands of dol- 

 lars, and moreover has discouraged further increase in production. 

 The present bulletin seeks to show how the potato plant grows and 

 Stores its starch and how parasitic fungi attack it. Then the foUowing 

 disease producing fungi are treated: Alternaria solani, Phytophthora 

 infestaiis, Corticium vagimi, and Oospora Scabies. The bulletin closes 

 with a discussion of spraying and the formulae for spraying mixtures.

A record of the occurrence in Cej^lon for the l^t time of the 

 Bud Rot of the Cocoa nut Palm. The disease, which is of a bacterial 

 nature, causes serious damage in the West Indies; methods of 

 prevention are advocated , no remed}^ for infected trees being known.

There has been some discussion as to the cause of the Hevea 

 root disease. Both white ants and the mycelium of a fungus are 

 found on affected roots. The author believes that the damage is 

 originated by a fungus, Fomes semitostus , Berk. that the white ants 

 play a secondary part, which may indeed be beneficial, in that ants 

 are known in other cases to devour wood containing mycelium or 

 even eat fungi themselves. A. D. Cotton (Kew).

Chlamydites Prainii n. gen. et sp. unica resembles certain Allar- 

 dias in habit, but the true affinity is with Cremaiithodium Deasyi, 

 Hemsl., the most important difference l5'ing in the presence of 

 remarkable villous tufts on the Segments of the disc-florets. The 

 diagnosis of the new genus is as follows: "Herba demissa, lanata, 

 scapigera; folia plerumque radicalia, parva. Capitula heterogama, 

 radiata homochroma (?); flosculi ? omnes externi uniseriati ligulae-
