Pear tree. On one tree a general and healthy bloom : — maximum,

Pyrus Japonica. On very many trees a scattered but healthy bloom 

 up to the present time.

Elder, [Scwibucus niger.) On one tree a general and most beautiful 

 bloom: — maximum, 17th September. 



Acacia. [Robmia pseiidacacia). On two trees a general and most 

 healthy bloom : — maximum, 11th September. 



I do not know whether these two trees had previously flowered 

 during the present year. 



In a great number of instances the lime stems have produced a 

 second and abundant covering of leaves ; but I have not observed 

 blossoms. In London and its immediate vicinity, the leaves remain 

 on the limes but a very few weeks ; in Wellclose Square, I have 

 known the trees entirely stripped before the end of July. In Bishops- 

 gate church-yard they usually remain ten days later.

On the occurrence of Juncus diffusus near Hoddesdon, and on its 

 specific distinctness from J. glaucus. By John Ansell, Esq.

On Saturday afternoon last, I paid a visit to Hoddesdon, in company 

 with Mr. Coleman of this place. We gathered Salvia verbenaca, 

 Stellaria glauca, Spergula nodosa, Polygonum minus, Mentha sylves- 

 tris, Silene noctiflora, &c., in the neighbourhood of Hoddesdon, and 

 were shown Iberis amara, growing with Delphinium consolida and 

 Calendula officinalis, in a corn-field there. In returning to Hertford 

 byway of Goose-green and Mangrove-lane, about sun-set, we diverged 

 into a barren pasture, (about three miles south of Hertford, and
