NOTES ON SOME PLANTS OF NOKTH-EAST CORNWALL. 237 



Ruinex pulcher, L. — Near Denhams Bridge, towards St. Kew, 

 and between the latter village and Amble ; between Washaway 

 and Egloshayle. Certainly indigenous. 



Parietaria diffusa, Koch. — Port Isaac. 



Ulmus suherosa, Ehrh., b. (jlahra. — In hedges, as a denizen at 

 least. 



Quercus Rohur, L., c. sessiliflora . — A considerable portion of the 

 oak in the hedges seems to be this. Trees in a wood between 

 Washaway and Egloshayle. 



Potamogeton crisjnis, L. — In the stream at Amble, which place 

 being in the parish of St. Kew, the station is probably identical 

 with that recorded as " St. Kew" in Keys's ' Flora of Devon and 

 Cornwall,' on the authority of Mr. Tellam. 



Orchis latifulia, L. — About St. Kew ; in a waste marshy piece 

 of ground between St. Mabyn Village and Tresarret Bridge. Only 

 the ordinary form of this found. I looked in vain for the peculiar 

 Orchis of the Lizard district, referred to in my 'Flora of Plymouth,' 

 p. 324, under " O. incarnata,'" as having been seen by me growing 

 there. I have no doubt this latter is the species of Mr. C. B. 

 Clarke's paper, recently published in ' Journal of the Linnean 

 Society,' vol. xix., 206-8, entitled, "On a Hampshire Orchis not 

 represented in ' English Botany,' " especially as Mr. Clarke states 

 it to occur in Cornwall. I am quite willing to adopt the conclusion 

 that the ordinary British so-called " Orchis incarnata,'' inclusive of 

 examples from a " bog on Crownhill Down" (' Flora of Plymouth,' 

 p. 324), is but a form of 0. latifolia, whilst that occurring in 

 Hampshire and at the Lizard is really a distinct species. I believe 

 the Cornish plant was first found by Mr. Ealfs, of Penzance, some 

 years ago. 



Hahenaria chlonuttha, Bab. — On the lawn atLavethan; between 

 Washaway and Slades Bridge. 



Lister a ovata, Brown. — Lavethan ; near Tresarret Bridge. 



Allium vineale, L. — Near Amble. 



Juncus glaucus, Sibth. — Denhams Bridge ; by the road to St. 

 Mabyn from Amble ; between Cakeval, St. Kew, and St. Endellion. 

 Local in Devon and Cornwall. 



Care.v vmricata, L. — By a roadside at Pencarrow ; near St. 

 Mabyn. 



(J. sylvatica, Huds. — By roadside at Pencarrow. 



C. distans, L. — In the marshy ground at Amble, with other 

 submaritime vegetation. 



Ayrostis setacea, Curt. — Washaway. 



Milium efusum, L. — In one spot, in proximity to a wood, 

 between Washaway and Slades Bridge. 



Arena Jiavescens, L. — Near Denhams Bridge, towards St. Kew ; 

 St. Endellion. 



Sclerochloa loUacea, Woods. — Port Isaac. 



Bromus erectus, Huds. — On and by a boundary wall or hedge of 

 a plantation by the turnpike road at Washaway ; in considerable 

 quantity, and extending for very many yards ; and, if not indi- 

 genous, evidently established at the spot for some considerable time.
