rsicolor, is represented by a row of hairs; so that a single 
amplexicaul bract may be represented by an intimate division 
of its parts, the divisions springing from the ve oint of in- 
sertion, and it is possible to consider that a single bract should be 
represented by a whorl of ee vy such is probably the case with 
e bristles present at the base orets of several Grasses. Le 
us for a pe consider the ea mens in some of the genera last 
mentioned also as a modified whorled single bract ; yet the position of 
the germen would not be that of Carez, for the stamens are in that 
genus situate on the secondary axis, and cannot surround the ovary. 
PROBABILITY OF THE OCCURRENCE OF CHENOLEA 
HIRSUTA IN GREAT BRITAIN. 
By Baron Ferp. von Murtrer, C.M.G., M.D., F.RB.S. 
many months ago I expressed surprise to a great writer on 
British: plants thatas yet Juncus pygmeus of Richard had tion: found 
in any ofthe British Islands. It was thus with particular interest that

The remembrance of Prof. Nolte’ 8 researches on the coast both of 
the Baltic and North Seas brings me to another rare plant, for which 
a search should be instituted along the British coasts. I allude to

among the far more widely-distributed Suda, intermixed with

1765, a fair figure of the downy form, and Prof, Nolte has lucidly demon- 
strated it ts synonymy. The embryo, horseshoe-shaped in Chenolea and 
circinate in Sueda, affords an unerring mark of distinction in cases 
where the pubescence of Chenolea hirsuta has become lost, or ra 
reduced to a slight beard in the axils. Moreover the Chenolea vel
