" I am engaged in an investigation of a form of Chenopodium com- 

 mon in garden-ground &c. about Kelvedon, and which I refer to Che- 

 nopodium ficifolium. Have you a specimen of this latter plant, with 

 characteristic lower leaves and perfect seed ? — -do you know of any- 

 body who has such a specimen ? — and could you get me two or three 

 seeds ?" 



The President regretted his inability to assist Mr. Varenne, but 

 hoped that some members of the Club would be able to do so. 



Species of Woodsia. 



The President read the following extract from a letter addressed 

 to him by Mr. Wollaston, of Eltham : — 



" I send you notice of an important observation I have made in 

 distinguishing the difference between the two Woodsias. W. llven- 

 sis, in the commencement of its growth, or its vernation, is of a light 

 bright-green colour, very scaly, and has no appearance of thecae until 

 the fronds are nearly matured, and have attained their full growth. On 

 the other hand, W. alpina is a very dark green, has very few scales, and 

 the fronds are studded with thecae as soon as they are visible. It is about 

 three weeks later than Ilvensis is in its first appearance above ground. 

 Alpina, moreover, is procumbent in habit ; whereas Ilvensis is erect." 



Arahis stricta and Trinia vulgaris. 



The President read the following extract from a letter addressed to 

 him by Miss Attwood, of 12, Clifton Vale, Bristol :— 



" While searching for Notolepeum Ceterach on rocks near Cook's 

 Folly, on the Gloucestershire side of Clifton, where it grows more 

 luxuriantly than on the opposite, or Somersetshire, side of the river, 

 I found a fine specimen of Arabis stricta, which grows more plenti- 

 fully in that locality than anywhere else in this neighbourhood ; but 

 I did not see our other rarity, — Trinia vulgaris, — although it grows on 

 a reef of rocks at a short distance off. Should you have any friends 

 who may particularly desire for their herbariums either Arabis stricta, 

 Hutchinsia petraea, or Trinia vulgaris, I have a few duplicates which 

 I shall have pleasure in sending." 



Nees von E sen beck.
