Notice of the Discovery of Allium splnerocephalum, L., on St. Vin- 

 cent'' s Rocks, Biistol* By H. 0. Stephens, Esq. 



I HAVE pleasure on forwarding you for exhibition at the next meet- 

 ing of the Botanical Society, specimens of Allium sphserocephalum, 

 L., previously considered to be a native of Jersey and not of Eng- 

 land. The enclosed specimens, which appear to be identical with 

 the Jersey plant, I gathered on St. Vincent's Rocks. It is not a lit- 

 tle remarkable that A. sphaerocephalum, a sea-shore plant in the 

 Channel Islands, occurs here on the steep declivities of the cliffs, 

 whilst A. oleraceum appears plentifully in the salt soil of the banks 

 of the Avon, below the Rocks, where I have not found a single plant 

 of A. sphaerocephalum.

Note on the Present Appearance of the Potato Crops around Bristol. 

 By H. O. Stephens, Esq. 



I HAVE carefully and anxiously watched the potatoes this season 

 in order to notice, not only the precise day and hour of the attack of 

 disease (if it unfortunately again appears), but also the atmospheric 

 conditions which may accompany it. 



Up to this date, August 10th, the crop is certainly generally sound, 

 and of unusual promise, not only as to quantity, but in quality. 

 True it is, that abundant rumours of disease were afloat a few weeks 

 since, and several samples were sent me for examination. There 

 was something wrong in these samples : the foliage was curled, yel- 

 low, and flaccid, and like the haulm of nearly ripe plants. The tu-
