REPORTS. 427 



Report of the Bottinical Section. 



Members of the Society Avho are interested in the work 

 of this Section will remember that last March a paper was 

 read summarising the notes which have been collected upon 

 the flora of our area subsequent to the publication seven 

 years ago of the Flora of Guernsey and the Lesser Channel 

 Islands. As this paper, when printed in the current number 

 of the Transactions^ will be foimd to include the most recent 

 information upon our phanerogamic and cryptogamic plants, 

 thus forming a complete supplement down to the end of the 

 present year, but little need be said now, consequently the 

 present Report will be a very short one. 



Two new flowering plants have been added to the flora 

 of Sark this year by Mr. Derrick, Sinajns alba and 8. 

 nif/ra, both of them Casuals, and both occurring in Guernsey, 

 though rare. The occurrence of alien plants, or Casuals 

 as they are technically called (/.e., species introduced with 

 agricultural seeds or ballast brought from other places), 

 is now attracting more attention than ever from botanists, and 

 therefore we must watch for and note any such when they 

 make an appearance within our limits. It is surprising how 

 few Casuals of foreign origin we have in Guernsey, con- 

 sidering the immense quantity of seeds and roots continually 

 being brought into the island from outside. 



An unrecorded fungus has to be added to our list, 

 Exoascus ( Ascomyces) deformans. It was found in early 

 summer by Mr. W. A. LufF in the Candie Grounds near 

 the entrance to the lower garden, where it infested an 

 almond-tree, causing " leaf -curl," and at a distance giving 

 it the appearance of being covered with red flowers. Many 

 other microscopic fungi, attacking trees, shrubs and vegetable 

 produce of various kinds occur here but are unrecorded, 

 for want of having been adequately studied, and their 

 identiflcation can only be satisfactorily determined by 

 specialists. 



Several specimens of the Fly Agaric {Amanita muscaria) 

 were found this year growing under a tree in the grounds 

 of Miss Domaille, La Colombelle, Ruettes Brayes. This 

 very handsome species is one of the most striking as well 

 as one of the most poisonous of the mushroom-like Agarics, 

 and may always be known by its rich crimson colour spotted 

 with white. It has only once before been recorded for 

 Guernsey.
