Leaf tapering from the middle equally to base and apex—

About twice as long as broad = oval.

About thrice „ = lameolate.

Leaf with more or less parallel sides and blunt extremities—

About twice as long as broad = elliptic.

��Middlesex Plants.-Ou some waste ground near the new South West India Docks I noticed last month (October) a very large quant v ot Ader Inpoluan, both rayed and not rayed. On the same -round occurred as introductions Scnecio vi^cosus and XcuUhium spim,un° The latter is not given as a Middlesex plant in the published Flora of that county I may also mention that in ISGfi I collected XantJdum Struma- Ynrn^i Chelsea; the latest date in the Flora is 1746, and the plant is 'vi± I" 'P>-o'^^'Wy extinct."

��ISOTE ON THE Supposed Cerastium pumili^m from Jersey (sec arde, p. 199).-As Dr. Trimen has been kind enough to allow me to sec some more specimens of the Craslinm which he gathered on the sand- hills of Jersey, I think it may be as well to state here that, on a second examma ion 1 have found no reason to change my former opinion, and I believe the plant is lypieal C. Idramlrmn, not C. pnmilnm. So far as my
