Retrospective Criticism. 469 



On Corollas being perforated by Bees [instanced in Vol. 

 IV. p. 93. 479., Vol. V. p. 74. 86. 753.]. — I can only ob- 

 serve, that I have repeatedly stood a considerable time, and 

 called others also, to witness the fact in my own garden, 

 more especially when the humble bee has been actively em- 

 ployed in piercing the bases of the blossoms of the common 

 honeysuckle (Lonicera Caprifolium L.); and although the 

 L. sempervirens Ait. grows along with them, its blossoms 

 generally remain untouched. — P. J. Brown* Thun, Canton 

 of Berne, Switzerland, April 5. 1833. 



Drosera rotundifblia does sometimes, although rarely, expand 

 its Blossoms, as represented in the Encyclopedia of Plants, 

 and in this Magazine in Vol. V. p. 110. 758., and Vol. VI. 

 p. 178. — Drosera rotundifolia and D. anglica are abundant 

 on two marshes, one about three, the other six, miles from my 

 residence. Although I am constantly exploring these spots, 

 I have never found the blossoms expanded at the former 

 station, which is on the same level as ourselves, viz. 1900 

 English feet above the sea ; but at the latter, which is, perhaps, 

 500 or 600 ft. higher, I have occasionally detected beautiful 

 specimens. C. P. (Vol. V. p. 110.) should sketch the plant 

 on the spot, as the flowers close as soon as placed in the vas- 

 culum, and I have never been able, by any treatment, to 

 coax them to a renewed display of their loveliness : the only 

 way to obtain specimens for the herbarium, is to be provided 

 with a small book of blotting paper, to receive them at the 

 moment of their being gathered. — Id. 



In relation to the Question of the Irritability of the Glan- 

 dular Hairs on the Leaves of the Droseras, as controverted in 

 Vol. IV. p. 135., Vol. V. p. 26. 491. 755., Vol. VI. p. 177, 

 1 78. — The near relationship between Drosera and Dionae^z 

 had, many years since, suggested to me the probability of the 

 glandular hairs of the former possessing irritability. Many 

 and varied have been my attempts to detect it, but hitherto 

 without success. — ■ Id. 



Swiss Habitat of Scheuchzeria, polustris and Carex heleo- 

 nastes. — If I could have the pleasure of conducting your 

 excellent correspondent Mr. Bree to these marshes, his prac- 

 tised eye might detect what mine have failed to notice; and 

 I should hope to point out to him some plants, among others 

 the rare Scheuchzerza palustris and (still rarer) Carex heleo- 

 nastes, which might afford him a momentary consolation 

 for the loss of his " charming boggy meadow," of which he, 

 in Vol. V. p. 200., speaks in terms which made my fingers 

 tingle with increased anxiety to shake him by the hand. — Id.
