This is a brief consideration of the rare plants of Guernsey and 

 Alderney with a mention of their localities. Trees and shrubs in the 

 Island come into leaf about 3 weeks later than in the Midlands, but 

 the smaller Vegetation has the same average period of flowering, 

 although it extends longer. The rarities include Isoetes hystrix, Cicendia 

 pusUla, Silene qiänqiievnlnera, etc. F. E. Fritsch.

Referring to Astragalns mollissimus. The author states his con- 

 viction that the plant is not poisonous and that the peculiar Symptoms 

 which follow its Ingestion by stock in large quanlities for a long conti- 

 nued period are due to malnutrition or a disturbed condition of the 

 digestive tract brought about by the innumerable uniceilular hairs that 

 form the characteristic pubescence of the leaf and seem to constitute 

 about one-third of the weight and over one-half of the bulk of the pow- 

 der in dried material. Trelease.
