wort). Ballota nigra (Black Horhound) was once found but has 

 left no traces. 



Utricularia vulgaris (Common Bladderwort) supposed to be 

 extinct, was rediscovered by Mr. John Roy in Alford, 1887. 

 Primula veris (Cowslip) is rare. Trientalis europoza (European 

 Chickweed Winter Green) is very abundant. Flantago maritima 

 (Sea Plantain) occurs far inland. Polygonum viviparum (Vivi- 

 parous Bistort) is frequent. Juniperus communis (Common 

 Juniper), though frequent, is by no means abundant here. Listera 

 ovata (Common Twayblade) has been added to the flora of the 

 district by myself. L. cordata (Heart-leaved Twayblade) is very 

 abundant ; I found once a vafiegated-leaved plant. Orchis 

 latifolia (Marsh Orchis) is on the increase. Gy?nnadenia 

 conopsea (Fragrant Gymnadenia) is common on moors. Habenaria 

 viridis (Green Habenaria) has become very rare. H. albida 

 (White H.) and H. bifolia (Lesser H.) are both rare. Iris Pseuda- 

 corus (Yellow Water Iris) still grows in the district as formerly 

 recorded. C. limosa and C. prczcox are, as far as we can make out, 

 extinct. Living in an intermediate district and having made a 

 special study of grasses, I find that here one great feature is the 

 intermediate nature of many of the forms. I have to acknowledge 

 my indebtedness to the Botanical Department of the British Museum 

 for kindly examining them. With their method of giving old 

 names instead of constituting new forms where the plants examined 

 are not quite normal I quite agree ; but the occurrence of inter- 

 mediate forms in such species as Agrostis, in my judgment, tends 

 to support the belief iri evolution in plants, the forms appearing to 

 differ only as a result of difference of situation. 



I have added to our lists Alopecurus agrestis and A. fulvus and 

 a variety of A. pratensis with bulbous roots, Phleum pratense var. 

 nodosum, Agrostis alba, one plant with blue -flowers, Agrostis 

 stolonifera (Fiorin Grass), and Aira fiexuosa (Wavy Hair Grass) 

 in a monstrous form. Catabrosa aquatica (Whorl Grass), recorded 

 as found by Rev. John Minto, is extinct as far as I can make out. 

 A distinct form of Dactylis glomerata (Cocksfoot Grass), a white 

 form of Cynosurus cristatus (Crested Dog's-tail Grass), and Festuca 

 sciuroides (Barren Fescue) are still found as recorded ; also F. 

 gigantea (Tall-bearded F.). Bromus asper and B. secalinus are 

 new records for district. Avena pratensis and A. flavesceus both 

 grow in the district. A. fatua and A. strigosa in fields. Triticwn
