in a few years, or be discovered in some similar locality ; for I can 

 scarcely doubt that it was truly wild, the place being so far from 

 houses, and the plant being an unlikely one to have been introduced 

 in so uncultivated and unfrequented a' part. It is worthy the atten- 

 tion of botanists residing in or visiting that neighbourhood. We were 

 too late in the season for most of the Orchideae, which grow there so 

 abundantly, and did not notice any plants of particular interest, ex- 

 cept Epipactis purpurata and Cynoglossum sylvaticum, which grew 

 abundantly on one part of the hill, opposite Burford Bridge. Scro- 

 phularia aquatica was growing on the driest sides of Box Hill, but 

 did not vary much in character. Dipsacus pilosus, Campanula Tra- 

 chelium, Nasturtium terrestre, Erigeron acre, Bromus secalinus and 

 Epilobium angustifolium, do not appear uncommon. 



My next expeditions were also unsuccessful, in search of Liparis 

 Lceselii, which plant is likely to be very soon exterminated in this 

 country, by the progress of drainage. The first of them was to Bot- 

 tisham Fen, where the plant was said to have been recently found, 

 but there is so little real fenny ground remaining, that it must be 

 nearly, if not quite extinct ; and though our party, consisting of four, 

 dispersed ourselves over the peaty moor, we were unable, after seve- 

 ral hours' careful search, to discover any trace of it. Here grow 

 Viola lactea, Apargia hirta, Alisma ranunculoides, Ranunculus Lin- 

 gua (very rare), Erysimum cheiranthoides, Myriophyllum verticilla- 

 tum, Schcenus nigricans, Juncus obtusifolius, Bromus erectus, Chara 

 hispida, &c. In returning by Cherry Hinton we gathered Bunium 

 Bulbocastanum, Orobanche elatior on Knautia arvensis, Linum pe- 

 renne, abundantly, &c. ; near Babraham Brachypodium pinnatum, 

 Astragalus glycyphyllos and hypoglottis, Orchis pyramidalis and Fi- 

 lago Jussiaei. Further on, near Hildersham, is a rich little spot, 

 scarcely a hundred yards in extent, on which grow Anemone Pulsa- 

 tilla, Potentilla argentea, Trifolium scabrum and striatum, Dianthus 

 deltoides, Thesium linophyllum, Hypochasris maculata, Phleum 

 Bcehmeri, &c. ; and in the corn-fields around, Silene noctiflora, Fu- 

 maria Vaillantii, Galium tricorne, Bupleurum rotundifolium, &c, are 

 often met with, also in a neighbouring copse, Aceras anthrophora. 



The second journey was to Burwell Fen, where Liparis formerly 

 grew plentifully. This fen, too, has been drained within a few years, 

 and to such purpose, that we were informed the land which was for- 

 merly worth only five pounds per acre, would now sell for thirty. 

 There is a fen beyond still undrained, where the plant may possibly 

 grow, but it was too full of Arundo Phragmites and Cladium Maris-
