Note on Symphytum. — There has, I think, been much con- 

 fusion between Symiiliytum perecjrinum of Ledebour and S. asper- 

 7'ivium of Bieberstein. I suppose this is partly from tbeir close 

 resemblance when they are not in flower. They both grow in my 

 neighbourhood (Tunbridge Wells), and I have not seen any men- 

 tion of a difference I find in the shape of the petioles of their 

 root -leaves. A cross-section of these will show this clearly. Li 

 S. peregrinwn the proportions of this are 4J (wide) by 4 (antero- 

 posteriorly) ; in S. asperrimum 3^ (wide) by 7^, the groove on its 

 upper surface being much deeper and narrower. This distinc- 

 tion is quite lost in the dried and pressed specimen, but in the 

 living plant always available. One of the plants has a much 

 wider limb, of a paler blue than the other. This I take to be the 

 true S. asperrimum. If in this I should chance to be wrong, the 

 distinction will still hold good, though in the reverse direction. 

 A corresponding section in the case of S. officinale purpureum has 

 its lower side (dorsum) much more widely curved than either of 

 the others. — Edward G. Gilbert. 



Plants of Scilly.— While sojourning among the Isles of 

 Scilly in September last, I landed on the Great Ganinick — a 

 conical pile of granitic rocks matted together by a dense growth 

 of bracken, brambles, sea-beet and grasses — and found on the top 

 Calamagrostis Epigeios in considerable quantity. This, I believe, 

 has not been previously noticed in Scilly, and is a rare plant on 

 the Cornish mainland. In a marsh near the coast on St. Mary's 

 a peculiar form of Juncus maritimus was abundant — so plentiful 

 that, a few weeks later, the crop was mown and carted away to 

 thatch a cottage roof. In its ordinary state /. maritimus is short 

 and stiff, with a panicle that is far exceeded by the sharp-pointed 

 lower bract. The Scillonian plant is weak and tall, 4 to 5 ft., and 

 the panicle is mostly larger and more diffuse, with a lower bract 

 that never exceeds it, and is often not more than a sixth or a 

 quarter its length. The only variety I find described — /. rigidus 

 Desf. — does not fit my plant. I suggest, therefore, that this 

 should be known as var. atlanticus. Of Eupliorhia Peplis, which 

 could not be found in Scilly some sixty years ago when Ealfs 

 searched for it, we saw fifteen plants. — Jas. W. White.

The importance of microchemical tests in the study of the 



anatomy and physiology of plants has long been recognized, 



though it has been greatly exaggerated by some writers and under-
