Worcestershire Record No. 23 November 2007 pp. 72-76
Compiled by Bert Reid
2006 was a somewhat less active year for Worcestershire plant recording after general recording for the Flora Project closed in 2004, so there were fewer new county records and new hectad records of native plants than in recent times. Nevertheless, a good number of interesting records are worthy of note.
Alien plants have been a feature of out flora for many years, with plants from all around the world appearing with wool shoddy, as garden escapes and recently from birdseed. In 2006, Harry Green alerted Bert Reid to some unusual plants growing in his garden vegetable plot. These had clearly originated from birdseed and with the regularly recorded Panicum miliaceum, Echinochloa crusgalli and Fagopyron esculentum were a number of less usual species. Ambrosia artemisiifolia was our 9th record, Amaranthus hybridus our 8th Abutilon theophrasti our 6th, Helianthus petiolaris our 4th, Guizotia abyssinica our 2nd, while best of all was a first county record for the Yellow Dodder , Cuscuta campestris. With increasing feeding of wild birds, we may anticipate an increase in such records, but many will bloom unseen in private gardens.
Another plant in Harry’s garden was Datura stramonium. It is not clear where this came from, but in arable fields at Charlton it has long been known as a wool shoddy alien. In 2006 it was abundant, with thousands of plants. Almost all were the normal white flowered form but there was a single plant of the purple form var chalybaea, last recorded in this same site when Christina Dony was collecting wool shoddy aliens in 1953.
Alien plants often appear in quantity for a short time in small sites where
disturbance occurs. John Day found such an area at a development site on the
north side of Oddingley Road, West Heath, Northfield, where out of 192 species
recorded, no less than 15 were new records for the hectad. These included a fine
mix of hortal and birdseed plants such as Amaranthus retroflexus, Ambrosia
artemisiifolia, Anaphalis margaritacea (6th record), Nicandra physalodes,
Nicotinia x sanderae (9th record), Rudbeckia hirta (3rd record), Solanum
rostratum (4th record), and a first county record for Sisyrinchium
californicum. A couple more new records from here are awaiting confirmation.
In the nearby West Heath Recreation Ground, John found our first recent record
for Pyrus pyraster ssp achras. This subspecies has pubescent leaves and
obconical fruits, but is doubtfully distinct from the widespread subspecies pyraster.
New county records of hortal escapes were Galanthus plicatus ssp byzantinus, Euphorbia characias ssp veneta, Pulsatilla vulgaris, Allium roseum and Geranium nodosum. Galanthus plicatus had been recorded earlier from Broadway Church, but in 2006 Roger Maskew collected here for determination to subspecies. He also collected the same subspecies at Great Comberton church. The Euphorbia is again a subspecific redetermination plus a new record, this time by Bert Reid. Pasqueflower is native quite near to the county in Gloucestershire, but Keith Barnett’s record from Hastings Road, Barnards Green is undoubtably a garden escape. A single plant was growing between paving slabs of a short driveway leading up to a garden gate. It was not from the garden in question, but it is grown in two nearby gardens, including Keith’s! A more acceptable hortal record was also by Keith Barnett, this time a substantial clump of Allium roseum from a hedgerow near Newland. A surprise new post-1987 record was Bert Reid’s Geranium nodosum right on the edge of the county by Cadmore Brook, well away from houses.
But what about native plants? They too have produced a few choice finds in the year. One of the greatest joys in plant recording is re-finding a plant long believed lost from an area. Ann Fells was carrying out a standard survey of a moderately rich cattle pasture near Ashon Wood on Bredon Hill when she saw a small rather dull looking rushy flush. Closer investigation revealed a small patch of Blysmus compressus; Bert Reid managed to find the plant again a month later. This is rare in Worcestershire with only 7 recent tetrad records and 15 altogether – the latest previous record from the Bredon Hill area was 1929. Roger Maskew also visited Bredon Hill, investigating the current status of some of its rarest plants. He found 1000+ plants of Polygala calcarea, many more than had been recorded in recent years. Hippocrepis comosa and Astragalus danicus had not been recorded since 1989 and 1991 respectively, so it was especially pleasing that he found good populations of both.
It is more that 100 years since Callitriche brutia was found at Malvern Common by S H Bickham. The only other records were from Welland Common and Castlemorton Common in the 19th C. During a flora outing to Hollybed Common in 2006, a Water-starwort was collected from marginal mud from by a pool. John Day later determined it as the lost C. brutia, an excellent find. Callitriche is a difficult genus requiring ripe fruits and close examination for determination, and our plant has probably been present all along. The same site visit produced the 8th county site for Festuca filiformis, locally frequent in the grassland; another plant requiring close examination for identification.
Wyre Forest can always be relied upon for interesting plants. Two trips led by John Day produced many of the Wyre specialities including Carex montana, Melica nutans and the recently re-found Pyrola minor. 4 good native plants were added to the Wyre Forest List. Cuttings of the disused railway had 2 sites for Agrostis vinealis while the trackside edge had many plants of Carex divulsa ssp leersii over a 15 m. stretch with a single plant about 60 m. further along. Also along the track was Luzula x borreri (and its L. forsteri parent). The final new plant here was the hybrid fern Polysticum x bicknellii in a gully below Lodge Hill Farm Meadows.
Dianthus deltoides is declining nationally and is now considered near threatened. We had only 2 records since 1987, so it was pleasing that Terry Knight managed to spot a small cushion in a crack in the footpath by Main Street, Broadway. The habitat strongly suggests that this record is probably a garden escape.
Critical genera usually supply several interesting records and 2006 was no exception. Hieracium has given Bill Thompson many headaches following Sell’s revision of the genus. Many specimens have required redetermination and field records have needed revisiting where possible, but by 2006 most of this work was completed. Some of the changes are noted in the detailed records, but a few species are still under final consideration. Next year’s report should see a full list of accepted taxa in the county.
Rosa is particularly well recorded in the county thanks to the detailed work by Roger Maskew. In 2006, a visit to Penny Hill Quarry produced two new rose hybrids for the county, R. micranta x rubiginosa and R. tomentosa x rubiginosa. Roger also added a fifth county record for the nationally rare R. obtusifoia x micrantha on a visit to Hipton Hill.
Dave Earl led a BSBI Rubus meeting in 2006. This was aimed mainly in vc 39 and included modern Worcestershire in Seckley Wood. A number of interesting brambles were found, such as Rubus anglofuscus, R. angloserpens, R. armipotens, R. condensatus and R. ulmifolius x vestitis. R. obscuriflorus was described in 1978 with the holotype selected as a 1954 record from Seckley Wood, so it was particularly pleasing to refind the species in 2006.
Taraxacum provided many new hectad records, including two new county records. Bert Reid found Taraxacum melanthoides on the wide grassy edge of an arable field in Hinton On The Green. This becomes our second dandelion species in the county but not vc 37. It was however a new vice-county record for vc 33. John Day’s record of T. scotiniforme from a disturbed roadside bank on Hockley Brook Lane was a good new record for vc 37. This is only the 23rd British record for the species and had not been recorded since 1991. Other good dandelions included T. acroglossum, T. altissimum, T. haematicum, T. laciniosifrons, T. planum and T. spiculatum.
Some recent records suggest that global warming may be extending the ranges of some traditionally southern plants into Worcestershire. A good example is the Guernsey Fleabane, Conyza sumatrensis. This was first noted in Worcester in 1995: this was our only site until 2002 when a new hectad record was from near Pershore. In 2004, three new hectads were added, with another two in 2005. The spread continued in 2006 with records from SO74, SO84 and SP04. It is fascinating to see the spread of a new alien in such detail.
Another mainly southern plant put in a first appearance in 2006. This was Capsella rubella, a plant apparently originating from the Mediterranean area and most frequent in Britain on the south coast. Paul Stanley and Mark Jannink found it on a grassy road verge on the Pershore to Evesham road at Hampton. It is worth looking out for this plant in future.
Plant of the year was a difficult choice in 2006 with so many candidates of different types and interests. The final decision was for a new county record of a native plant that is spreading from the south, probably reacting to rising temperatures. This is Poa infirma, which was found by Paul Stanley and Mark Jannink at the same place as their record for Capsella rubella. The plant was common in a narrow band around a grassy area, mainly at the interface with the roadside pavement but with a few plants scattered within the grassland. Bert Reid found a second site in Pershore, where two patches were growing on the pavement edge of two adjacent front lawns in a cul-de-sac.

Centaurea nigra agg: this taxon has been split by Peter Sell into two species – initial investigations, mainly in the southeast of the county, suggest that most knapweeds here match his Centaurea debeauxii, with both rayed (ssp thuillieri) and unrayed (ssp nemoralis) represented. C. nigra sensu stricto appears rare with only one example of the rayed subspecies rivularis found. The picture may be different in the north and west of the county and some more or less intermediate plants may be the hybrid.

Hieracium: Peter Sell has made many taxonomic changes to the hawkweeds, a number of which alter our records. Bill Thompson is carrying out a full revision of our records, which will be completed in 2007 / 8. Among changes already dealt with are the split of H. acuminatum into H. acuminatum s.s., H. argillacium and H. consociatum. H. anglorum is reasonably widespread in the county (39 tetrads), H. eboracense is in 17 tetrads, and H. prominentidens in 8 tetrads. All our records for H. diaphanum are errors for other Vulgata species and all our H. rigens are now considered H. salticola. Our record of H. trichocaulon has been redetermined as H. calcaricola and our H. lepidulum record is now considered to be H. anglorum. H. sabaudum has been split into two forms and H. umbellatum to three. Ongoing work includes the H. exotericum agg and it is hoped to give a full summary of our Hawkweeds next year.
