ATRIPLEX L.

Atriplex hortensis L. (Garden Orache) 1982 - General Very Rare Only recently recorded at Bath in 2020s by ? [BSBI record]. Otherwise recorded at ST76 in 1982 by ? [BSBI record] and at Avonmouth in 1998 by Wessex Water.
Atriplex rosea L. (Redscale) 1922 General Extinct A native of the Mediterranean and the Middle East; "A number of large bushy plants on a tip at Brislington, 1915" (White, 1918); Ashton Gate in 1922 by C.I. Sandwith [BMAG]; Eastville in 1919 by J.W. White and T.H. Green.
Atriplex tatarica L. var. tatarica (Tatarian Orache) 1917 General Extinct A native of the Mediterranean and West Asia; recorded at St Philip's Marsh in 1915 by C.I. Sandwith and T.H. Green; there again in 1916 by G.C. Druce; by the canal near Bath in 1915 by C.I. Sandwith; Brislington in 1915 by G.C. Druce; Ashton Gate in 1917 by C.I. Sandwith (as var. integrifolia - no longer recognised); Avonmouth Docks in 1928 by C.I. Sandwith.
Atriplex prostrata Boucher ex DC. (ssp. prostrata) (Spear-leaved Orache) / General Frequent Our most frequent Atriplex by far; found in all manner of disturbed places such as roadsides, arable fields, manure heaps, newly made ground, and along the coast; particularly in the upper reaches of saltmarsh and on the muddy banks of tidal rivers. It displays a huge range of variation depending on habitat; being more fleshy and succulent by the sea to thin and spindly inland.
Atriplex glabriuscula Edmondston (var. glabriuscula) (Babington's Orache) / Coasts Scarce Scattered and localised along the coast on sand, shingle, upper saltmarsh and along the muddy banks of the tidal Avon and Axe. The var. virescens "A luxuriant dark-green fleshy plant, with leaves up to three inches in length, and perianths more than half an inch across; growing on clay or alluvium" (White, 1912), was probably referable to the next species or their hybrid.

from the dunes at Sand Bay to the shingle at Severn Beach and along the muddy banks of the tidal Avon.

Atriplex glabriuscula x A. longipes = A. x *taschereaui Stace (Taschereau's Orache) Coasts Very Rare An overlooked hybrid; found at Pill Marsh during a BNS meeting in 2021 by C.M. Lovatt and also at Severn Beach in 2020s by ? [BSBI record]. It is said to be more frequent than A. longipes (probably due to it being hybridised out of existence) and to occur in absence of it. It is similar in appearance to A. glabriuscula but has larger bracteoles (up to 20 mm - up to 10 mm in A. glabriuscula) which are foliaceous at the tip and has stalks up to 10 mm (sessile in A. glabriuscula*).
Atriplex longipes Drejer (Long-stalked Orache) / Coasts Scarce Scattered along the banks of the tidal Avon where it was first noted in 1977 by I.F. Gravestock and determined by P.M. Taschereau. Also recorded from Severn Beach, Portishead and Sand Bay. It is still probably overlooked.

Atriplex littoralis L. (Grass-leaved Orache) /- Coasts Rare Very rare on the coast; predominantly in the south of the region but can be locally abundant in some places such as at Sand Bay. It is also occasionally found inland along salted roads. First recorded in our region from Weston-super-Mare (Brody, 1856).

Atriplex laciniata (Frosted Orache) / Coasts Very Rare Occurs in small but variable quantity along the strandline at Sand Bay and formerly grew from time to time on the sand hills at Uphill. Also found at Severn Beach in 2011 by ?.
Atriplex halimus L. (Shrubby Orache) / Coasts Very Rare One large plant grows at Anchor Head, Weston-super-Mare where it was first noted in 1992 by C. & M.A.R. Kitchen.
Atriplex barclayana (Benth.) D. Dietr. (Barclay's Orache?, Barclay's Saltbush, Sonoran Saltbush, Dwarf Saltbush) General Extinct A native of California and North West Mexico; recorded at Avonmouth in 1961 by ? - a first and only record for the British Isles.
Atriplex portulacoides L. (Sea-purslane) / Coasts Very Rare Found in saltmarsh, and on exposed rocky and muddy banks; predominantly along the River Avon but also in several spots along the coast. It appears to have increased its distribution since the turn of the Century.

CHENOPODIUM L.

Chenopodium acuminatum Willd. (Acuminate Goosefoot, Mexican Tea) 1931 - General Extinct Native to North and Central Asia; recorded at Bristol harbour in 1931 by I.W. Evans - thought to be a first and only record for the British Isles.
Chenopodium vulvaria L. (Stinking Goosefoot) 1930 General Extinct Historically occurred as a casual on tips and around working yards, and persisted for many years by the Gas Works at Bath: "On Waste ground near the Feeder Canal, St. Philip's, Bristol, Aug. 1910, and again in 1911; very fine but in small quantity...One plant on a fowl run by Baptist Mills, 1911...Bath; on waste ground, not very frequent; Fl. Bathon. (1834). By the Gas Works at Bath; F. Inman in Fl. Bathon. Suppl. (1839). Bath; under the walls of the Gas Works and adjoining walls, not very plentiful, Sept. 1886; D. Fry...The plant was more abundant in 1894, and I saw it again in fair quantity in October, 1896. Casual near Twerton, 1897; S.T. Dunn. About a dozen fine plants on refuse in Portishead Station-yard, 1906; and again in four succeeding years." (White, 1912). Added is an amusing quote from D. Fry written in 1886 "It occurs almost exclusively close to the Gas Works, the stench from which harmonises well with the unutterably fetid odour of the plant. This Goose-foot certainly does not flourish beyond stink-shot from the purifiers of the Works!" Also found at Portishead South in 1914 by C.I. Sandwith; Eastville in 1917 by I.M. Roper; and Ashley Hill in 1932 by C.I. Sandwith. A reference made by Johnson (1632) "Atriplex olida...juxta semitas in suburbiis" [Atriplex olida...along paths in the suburbs] is queried by White to have possibly related to Bath, where Johnson was for some time residence.

[Where's the 1930 record?]

First recorded from our region on "Waste ground about Weston-super-Mare, 1843; G.S. Gibson" (White, 1912). White also gives Sowbane as an alternative name. The var. microphyllum (no longer recognised) was recorded at Brislington in 1916 by M. Cobbe; Wee Lane [now Glenfrome Road] in 1925; Bedminster Tip in 1926 [BMAG]; and Avonmouth Docks in 1928 by C.I.

Oxybasis ambigua (R.

Oxybasis rubra (L.) S. Fuentes, Uotila & Borsch (Chenopodium rubrum L.) (Red Goosefoot) /- General Uncommon Native along the coast in upper saltmarsh and also inland besides ponds, reservoirs, ditches and other marshy places. Also frequently encountered on manure heaps, arable fields and roadwork sites; sometimes occurring on mass. Red Goosefoot is very variable in growth habit depending on ground conditions; as described by White (1912) "Plants about byres and old dung-hills are usually very luxuriant; but on poor salt-marsh ground they sometimes run down in stature to a few inches, and have a branched, spreading habit. Three varieties are mentioned and recorded by Sandwith (1932) but are no longer recognised: var. blitoides was found at Portishead in 1914; var. kochiiforme occurred at Bedminster from 1926-30, and Avonmouth Docks in 1930; and var. spathulatum was found at Bedminster in 1930. A fourth, var. pseudobotryoides, with a short stature and branched spreading habit, was "only a dwarf state dependent on deficient nutriment." (White, 1912).

Oxybasis urbica (L.) S. Fuentes, Uotila & Borsch (Chenopodium urbicum L.) (Upright Goosefoot) 1925 General Extinct Formerly occurred as a rare alien. "Near Bristol; Worsley Cat. in New Bot. G. One large plant on cultivated land by the Avon under Sneyd Park, Sept. 1893. Several plants on house refuse brought from Bath and deposited by the Avon at Newton St. Loe, 1892; D. Fry. About half a dozen were observed on neglected garden ground at Bath in 1893 by Mr. A.E. Burr, who showed me his specimens. 'On waste and cultivated ground, frequent;' Fl. Bathon. But that was evidently one of Babington's looser statements. Weston-super-Mare...T.B. Flower in Herb. Boswell." (White, 1912); St Philip's Marsh in 1915 by C.I. Sandwith and T.H.
