362 THK GENUS XYSMALOBITIM.
Trifolium arvense L. Sparingly at Clogber Head. T. hybridum
L. Cotmuon in fields.
Valerianella Auricula Dietr. In corn-fields by the sea.
Sihjbum Marianurn Gaertn. lioad-side.
Cuscuta Trifolii Bab. Clover-field.
CynoglusfiUm officinale L. Waste places by sea-sbore.
Mertensia maritima Don. Sparingly on shores of Dundalk Bay.
Hyoscyamus tiiger L. Sea-shore.
Orobanche HedercB Duby. Plentiful in Castle Woods. 0. minor
L. In same field "with Ctiscuta Trifolii. The farmer did not know
the name of either plant, but said they both appeared in his fields
about three years ago. They are plentiful there now.
Utricularia minor L. Ardee Bog and Flack.
Oldone portulacoides Moq. Salt-marsh.
Hydrocharis Morsxis-ravce L. Plentiful.

Kpipactis palus^.tris L. Marshy ground.
ALIiuiH. carinatum L. (Fries). A dozen or more plants growing
on a grassy bank near Maine House, 1^ mile from Castlebellingham.
There used to be a garden next the bank, but it was ploughed up in
1880, and the field has been arable land ever since ; so the Allium

Juncus ohtusifloriis Ehrh. Marshy ground near the sea.
Potamogeton obtiisi/olius Mert. & Koch. Flack.
Cladium Meniscus R. Br. Marshy ground.

Geuni rivale L. Damp woods at Rathaugan, Co. Kildare, 1887.
Atriplex arenaria Woods. Sea-shore near Newcastle, Co. Down,

By G. F. Scott Elliot, M.A., F.L.S.
This small genus is closely related to Gompilocarpus, and
may be regarded as an offshoot from the section Paclu/carpiis.
The eleven species represented in the Kew and British Museum
Herbaria show a very interesting distribution. None are (so
far as one can judge from the imperfect Libels of most collectors)

in the arid plains of the Karroo ; but the mountain-summits of
Cafi'raria, the table-land of the Transvaal, Basutoland, Griqualand
East, Natal, Zululand, aud the Shire Highlands are all inhabited
by one or more of the wide-ranging species. Two species are
