RECORDS OF INTERESTING GRASSES IN SUFFOLK 1960-61 by P. J. O. TRIST
DIGITARIA SANG UIN ALIS (L.) Scop. Crab Grass or H Finger-Grass. Earliest record for Suffolk 1780, Hind. No recent records until found at Snape Priory in 1960. A native of the Mediterranean and occasionally occurring in this country on rubbish heaps and on cultivated areas. SETARIA VERTICILLATA (L.) Beauv. Rough Bris Grass. Not recorded for Suffolk by Hind. Found in a carrot bed in my garden at Bury St. Edmunds in 1960 : and another plant appeared in 1961, with seven panicles. The greatest culm of 96 cm. with a panicle of 11.5 cm. : the longest leaf 33.5 cm and 22 mm. wide. This grass is a rare alien of waste and cultivate ground ; a native of the Mediterranean region. CORYNEPHORUS CANESCENS (L.) Beauv. Gre Grass. A very local grass. Recorded by F. W. Simpson on Benacre denes where he says it was formerly abundant. I confirm the record in 1960 but it is likely that the original number of plants is much reduced, owing to the encroachment of the sea by the build-up of shingle at Benacre Ness. Also recorded at Minsmere, 1961, by Mrs. B. H. S. Russell (B.S.B.I.). POA BULBOSA (L.). Bulbous Meadow-Grass. Previously recorded by F. W. Simpson and I confirm the record in 1960 in a fairly safe position. E. A. Ellis of Norfolk had records for Lowestoft north denes but failed to find plants in 1957. My own survey in 1960 failed to find a plant. BROMUS DIANDRUS Roth. Great Brome. The earlie county record given by Hind is 1879. There is also a record for 1936 from F. W. Simpson at Felixstowe docks. In 1961 I found one plant on an arable boundary at Lower Farm, Troston and also many plants on either side of the main road by the caravan park o entering Brandon from the south-west. Another native of the Mediterranean region and found in this country on arable and waste ground. BROMUS COMMUTATUS Schrad. Meadow Brome. grass which would have been comparatively common in old pastures up to the outbreak of the last war and now becoming very uncommon owing to farming improvements. The var. pubens Wats., was found in the Fritillary meadow at Framsden 1960 and determined by C. E. Hubbard. A variant with hairy spikelets probably B. commutatus x B. mollis in origin. BROMUS INERMIS Leyss. Awnless Brome. Several plants on a reseeded playing field at Lakenheath, 1961. A native of central Europe and temperate Asia. HORDEUM JUBATUM (L.). In the same field as Bro inermis above, 1961. A native of North America. M ov, j Uc< ca,<U> \<>h/M
