LabiaUe. Mentha piperita and M. rotundifolia. Leonurus cardiaca, 

 a rare plant, is not unfrequent near Doncaster. The same may be 

 said of Ballota nigra, which, though generally diffused throughout the 

 vale of York, is rare in the higher parts of the county. It occurs with 

 white flowers near Doncaster. Nepeta Cataria and Origanum vul- 

 gare may occasionally be noticed on bushy hedge-banks. 



TJiymelecB. Daphne Laureola occurs in the wildest profusion in the 

 hedges near Brodsworth, far from any trace of garden cultivation. Its 

 early flowering and delightful fragrance render it a general favourite. 

 Exotic species of Daphne thrive well when grafted on our wild stocks. 



Euphorbiacea. Euphorbia platyphyllos 1 have met with on arable 

 land, wiiere it has no doubt been introduced with seed-corn. 



AroidetB. In the ditches at Askern, Sparganium simplex is as com- 

 mon as S. ramosum. 



AlismacecB. Alisma ranunculoides and Sagittaria sagittifolia. The 

 bulb which grows at the lower part of the root of the latter plant is 

 said to constitute a part of the food of the Chinese. 



Hydrocharidece. Stratiotes aloides, which occurs chiefly in the 

 east of England, is common in the fens near Doncaster. The struc- 

 ture and economy of this plant are exceedingly curious. 



Orchidete. The Roman Ridge is richly productive of our repre- 

 sentatives of this singular tribe of plants. Orchis ustulata, O. pyra- 

 midalis, Gymnadenia conopsea, Habenaria bifolia, Ophrys apifera, 

 O. muscifera, Spiranthes autumnalis, Neottia Nidus-avis all occur 

 within a very limited range. 



Amaryllidea. Narcissus biflorus, a doubtful native, grows and 

 flowers abundantly in a grass-field not far from the village of Adwick. 

 Its ally, N. pseudo-narcissus, known in Devonshire by the name of 

 the Lent lily, is exceedingly plentiful in Hampole Wood, covering 

 hundreds of yards with its simple yellow bells. 



Asparagece. The woods around Doncaster abound with Conval- 

 laria majalis, which flowers much more freely its wild state than when 

 in cultivation. Paris quadrifolia, not unfrequently belying its specific 

 name by presenting whorls of 2, 3, 5, 6, 7, and 8 leaves, is very com- 

 mon throughout the greatest part of the county. 



LiliacecB. Ornithogalum umbellatum grows in several patches in a 

 pasture between Adwick and Pigburn, and flowers well. The locality 

 in which it occurs does not exhibit the slightest trace of garden culti- 

 vation. 



Cyperaceas. Noble plants of the rare Cladium Mariscus grow in 

 the fens at Askern. Babington says of this interesting plant "rare
