well-known fungus Phytophthora infestans growing in the diseased 

 portions (usually just within the skin) . Soft rot bacteria were present 

 in some cases and Fusarium in many, but the initiation of the rotting 

 was undoubtedly due to Phytophthora. Phytophthora was by no means 

 abundant on the foliage of potatos during the past season, and in the 

 former case it was definitely stated that no disease had been present on 

 the tops of the plants during the growing season. The origin of the 

 attack upon the tubers is therefore somewhat mysterious but by no 

 means unprecedented, for the rotting of tubers stored while damp 

 is very frequently brought about by this fungus. Inquiry showed 

 that in the present cases the tubers had been exposed to damp weather 

 conditions immediately prior to storing. In some instances the rotting 

 had immediately followed upon the storing, having made noticeable 

 progress within three or four days, although when put into the " pies " 

 the tubers were apparently without damage. 



Phalaenopsis Lindenii. — A Philippine Phalaenopsis was exhibited 

 on December 2 by Messrs. Stuart Low, Jarvisbrook, which Mr. 

 R. A. Rolfe reports is Phalaenopsis Lindenii Loher, a plant described 

 in 1895 (Journ. des Orch. vi. p. 103). M. Loher, the original discoverer, 

 remarked that it was somewhat like P. Sckilleriana in the leaves and 

 P. rosea in the flowers, but no other Phalaenopsis was found growing 

 with it, so that it is uncertain whether it is a species or a natural 

 hybrid. The record suggests that it might possibly be a form of 

 P. Veitchii, but the flowers are not identical, the hp being simply 

 apiculate at the apex, and without the small anchor-shaped tendrils 

 of the latter- Messrs. Stuart Low believe that the plant came home 

 with Phalaenopsis Aphrodite. Its history was given in the Orchid 

 Review, xv. p. 296.
