just what we find in a normal ear of Maize, with its twelve rows 

 of grains in alternating pairs, an arrangement which has hitherto 

 always puzzled me. I have no access to any description of 

 Euchlcena, and it would be interesting to learn Whether in that 

 genus the arrangement of the grains upon the spike is such as I 

 have indicated. In this Journal for 1909, p. 180, it is stated that 

 Zea hybridizes with Euchlmna. — Henry Peirson. 



Lincolnshire Notes. — In the ruined collection of the late 

 Eev. Joseph Dodsworth, Vicar of Bourne, which reached me in 

 1893, was a Lincolnshire specimen of Suceda fruticosa Forsk., 

 dated 1836. The locality was not given, and its home has been 

 fruitlessly searched for ever since. Mr. H. A. H. Healey, of Dawes- 

 mere, Holbeach (53 S. Lines.), sent me a beautiful specimen in 

 July with the following note : "In fair quantity seaward side of 

 the seabank here." Mr. B. Eeynolds, writing from Skegness in 

 July last, reported a variety of Papaver Bhceas L. with the yellow 

 sap of P. Lecoqii Lam. Later he wrote : " The fruit is globular, 

 the hairs on the peduncle spreading ; everything is characteristic 

 but the juice." Personally I have never met with this form. My 

 experience as a worker leads me to believe that Bumex maritimus L. 

 and R. limosus Thuill. are but one species, with two forms accord- 

 ing to the season. After a series of wet summers B. maritimus may 

 be found round every sandy inland pond, and not a few clay-pits 

 too. After a few dry seasons it cannot practically be found any- 

 where inland, with one exception — the permanent peat-ponds or 

 "flashes " on thin sand overlying clay. The curious thing to note 

 is that after a series of wet summers the very same pond supplies 

 the tall limosus form, with its characteristic fruits ; after a series 

 of dry seasons, the maritimus form, four to six inches high, with 

 its typical fruit. Why this change, I ask, on the limited area of an 

 acre, if these so-called species are not climatic forms? — E. A. 

 Woodruffe-Peacock. 



Erigeron acre X canadense = E. HuLSENii Kerner, vol. ii. 

 p. 585.— On the Somerset side of Bristol, at Ashton Gate, Erigeron 

 acre and E. canadense both grow in some quantity on the site of 

 abandoned ironw^orks, and amongst them I have lately detected a 

 hybrid intermediate in characters and sterile. This plant, of 

 which a good number were seen, is from four to ten inches in 

 height, of graceful habit, with pale lilac or bluish purple flowers, 

 quite different from the dull red-purple tint of E. acre. The 

 hybrid must be extremely rare, as only one mention of its previous 

 occurrence in this country seems to be on record — a single speci- 

 men near Tilford, Surrey, by the Eev. E. S. Marshall, in 1881 

 (Journ. Bot. 1907, p. 164). Mr. J. W. White sent examples to the 

 Eev. E. S. Marshall, who writes that his Surrey plant was large 

 and spreading, with considerably larger heads than those of mine, 

 and was not so good an intermediate, but that all are practically 

 identical in leaves and phyllaries. The fruits are found to be of 

 medium size, but empty. There is no record for this hybrid in the 

 French Floras, but it is given by Focke from several places in 

 East Germany. — Ida M. Eoper.
