ISLE OF WIGHT PLANTS 233 



which in September, 1909, I found in vast profusion growing all 

 over the burnt portions. The nearest locahty to this in which 

 E. angustifolium grew is in the Blackwater valley a mile or so 

 distant, but in the direct course of our prevailing wind from the 

 south-west. 



Stachys germanica L. In September, 1909, Mr. E. W. Hunny- 

 bun sent me a specimen from near a chalk-pit above Steephill. 

 This plant has not hitherto been noted for the Island and appears 

 to be either very rare or extinct in Hampshire. 



HEETFORDSHIKE POPLARS. 

 By J. E. Little, M.A. 



The following notes refer chiefly to North Herts, but a few 

 records from other districts, also from my own observation, are 

 included. 



The nomenclature of the Cambridge British Flora is followed. 



"POPULUS ALBA L. ( $ Only). 



(1) Herts v.c. 20. (Larger trees only are mentioned.) Four 

 trees on the left bank of the Ivel, between Norton Mill and 

 Radwell Mill, averaging 80 ft. in height, 12-13 ft. in girth at 

 3-4 ft. from ground, with a spread of 70-80 ft. See Watson 

 Bot. Exch. Club Report, 1912-13, p. 409. These are probably 

 Coleman's record, "Riverside near Radwell" {Flora Hertfordiensis, 

 1849). — Two trees in a spinney south of Oughton Head Common, 

 Hitchin : height 65 and 60 ft. — Weston Park, Stevenage : an 

 avenue planted by Mr. M. Pryor about forty years ago. — 

 West side of Cadwell Common, on the lane: one tree, height 

 about 60 ft. — Garden at Hertford Heath, at the junction of the 

 Roman Road with the main road, one tree. There is also a 

 P. canescens Sm. S at the same place. This may be the tree 

 of which Coleman (o^;. cit.) remarks : " By Herman St., a quarter 

 of a mile S. of Hertford Heath, the only fertile tree we have 

 observed near Hertford." But I have not seen mature catkins 

 upon it. — Haileybury College, near the Swimming Bath. A row 

 of trees about thirty years old. 



(2) Beds v.c. 30. Cadwell Bridge, near Ickleford, on the right 

 bank of the Hiz, one tree : height 78 ft. 6 in., girth at 4 ft. from 

 ground 12 ft. 4 in., spread 73 ft. Det. C. E. Moss. 



(3) W. Suffolk v.c. 26, near Denardiston Hall, one tree. 



P. ALBA VAR. PYRAMiDALis Buuge. (See Elwes and Henry, 

 Trees of Great Britain and Ireland.) A fastigiate form with 

 the outline of a small Lombardy poplar. Herts. Garden at 

 Highbury cross roads, Hitchin, one tree. Garden of " Otterburn," 

 The Avenue, Hitchin, one tree. I have not yet seen catkins on 

 these trees, which are not more than twenty years old.
