It. obtusifolius x pulcher [561]. Windmill Hill, Hitchin, 
Herts. Leaves 15/6/23, flowers 26/7/23, fruits 17/9/23. E. G. 
Baker assents. — J. E. Little. This shows good evidence of both 
parents. Well-formed nuts are present, slightly larger than those 
of pulcher , and paler in tint. — C. E. Salmon. 
It. obf/usifolius x viridis [564]. Wallington, W. Norfolk, Aug. 
9, 1923. Stems and undersides of lamina ± papillate. Flowering- 
branches ascending, rather long and lax, whorls not confluent. 
Flowers (all ?) sterile. Fruiting segments show some reticulation, 
narrow, oblong. Teeth occasional. Tubercle varying from oval 
to elongate acute. Pedicels jointed below the middle and unequal 
distances from the base. Both supposed parents were close at 
hand. — J. E. Little. Your plant is very interesting, and 1 should 
say that the identification is correct, but should have liked to 
have seen lower leaves. There is a very good paper on Rumex 
hybrids in Vol. Ill “ Mitteilungen cler Geographischen Gesell- 
schaft,” by Haussknecht, but he only gives obtusifolius into 
sanguineus , and not hybridising with viridis. — E. G. Baker. It 
looks quite right. The leaves and petals point to this hybrid. 
— C. E. Salmon. I think the hybrid suggested = x It. Duftii 
Haussk. The plant received, which resembles It. viridis , has 
nearly all the perianths quite undeveloped, but there are one or 
two which clearly show the toothed sepals, and large tubercle 
seen in It. obtusifolius. I have collected this hybrid in Surrey 
with a much larger proportion of fruiting perianths. — H. W. 
Pugsley. 
Ulmus : — Specimens of Ulmus would be much more valuable 
if notes were made on the labels as to the habit of the tree, the 
character of the bark, the date of flowering, and whether the 
lower branches are corky.— A. B. Jackson. 
Ulmus minor Mill. Teste A. Henry [534], Near Wymondley 
Springs, Herts, Feb. 16, and Aug. 30, 1923. No fruit produced. 
Leaves turn in September. — J. E. Little. Ulmus minor Miller. 
— A. Henry. Correct. I have found it a frequent roadside tree 
in Leicestershire and Nottinghamshire, and have also seen it in 
other Midland counties.- — A.B.J. 
U. hollandica Mill. (537). Below Brook End, St. Ippolyts, 
Herts., v.c. 20, Feb. 17, May 17, Aug. 23, 1923. Tree about 
70 feet, with wide spreading branches. Of 25 flowers examined, 
4 had 3 stamens, 15 had 4, 5 had 5, and 1 had 6 stamens — 
J. E. Little. Ulmus nitens, var. This has leaves and samarae 
much too small for Ulmus major Smith, which I consider to be
