A third form, from Falcon Clints, on the Durham side of the Tees, 
has the corolla and manner of growth of T. Serpyllum, with linear- 
lanceolate lower calyx-teeth, just equalling the upper ones; the leaves 
and lowest bracts obovate-spathulate, nearly twice as long as broad, 
including the haft, hairy not only all along the edges, but over the 
blade, and the stems densely hairy with rough hairs. 
Stachys palustri-sylvatica, Schiede. Mr. Briggs sends from the 
border of a garden at Stoneybridge, Devonshire, and Mr. Bromwich 
from Beausale Common, in Warwickshire, examples of a not uncom- 
mon plant which eomes about midway between typical S. palustris and 
the true S. ambigua of Smith. The leaves are narrower, less cordate, 
and less deeply-toothed than in this latter, and the stalks under 3 inch 
long. These agree very well with an example marked S. ambigua, 
from Professor Boreau. 
Rumex pratensis. Detected by the Rev. W. W. Newbould last 
summer in several stations ranging for altitude from 150 to upwards 
of 400 yards, in the dales-of Durham and Northumberland (Teesdale, 
Weardale, and Allendale). This extends the north limit a province 
beyond what is stated in the ‘Cybele,’ and some of the localities come 
decidedly within the Superagrarian zone. 
Surrey Chenopodia. Mr. Watson sends us this year, as he did last, 
a series of packets of Surrey Chenopodia, with which he writes: “ The 
Chenopodia from Surrey are sent. in continuation of a former series. 
The packets include various forms of C. rubrum and C. urbicum or 
intermedium. In the * Flora of Surrey’ a dwarf Chenopodium is given 
under the name of C. botryoides ; but the specimens formerly distributed 
. and supplemented by those now sent, suffice to show that the so-called 
AS botryoides of the Poney Flora is really a state or a of C.
