NOTES ON BRITISH ELMS 69 
This Elm is said to ne been first brought into notice in 1836 
by a John Wood, a Huntingdon nurseryman, whose uncle, a 
market gardener, tales it from seed collected in the neighbour- 
hood eighty or ninety years before (Loudon). Plants said to be 
aint of the original trees are still shown at Huntingdon. 
t has been universally, so far as now, regarded up to the 
valine time as a hybrid. I have ventured, without eaenon a 
the question of its hybrid origin, we treat it in this paper 
independent species, looking to its samara characters, the fertility 
of its seeds, and the presence of suckers. I am, however, inform 
by Dr. Moss that experiments conducted at Cambridge in 1909 
point to hybridity (U. glabra Mill. x seabra Mill.). It can usually 
be recognized from U. scabra at a distance by habit alone.

“U, (gla hots folits ovatis ae globes ave serratis. The Smooth- 
leaved Witch Elm,” Mi ller ‘“‘Glabris”” is corrected by Miller on 
his last page to « glaber.’ 
Samara varying in size, broadly obovate or oblong; notch 
open or closed at the top, very conspicuous, its basal angle rather 
obtuse, reaching mec the seed cavity, which is short and 
one pointed ; seed maturing. 
oung twigs, buds, snd petioles more or less hairy; leaves 
slightl Ny scabrous or smooth above, often plainly glandular beneath, 
so the samara (var. Sep here Lindl.), epilose above and 
below except on the midribs ondary veins and at the axils; 
ovate or obovate-cuneate, say 6 or longly acuminate, very un- 
equal at base ; varying much in ig and pga but pre always

variety of this species. oe U. glabra is much better fitted for this
