HERTFORDSHIRE POPLARS 



235 



-■'P. ITALICA Moench (= P. nigra var. italica Du Eoi). 

 Herts. Lane between Grove Mill and Hyde Mill, Ickleford. 

 Cadwell. Much planted as a wind screen. 



P. NIGRA L. (b) VAR. BETULIFOLIA ToiTey. 



(1) Herts. Left " bank of River Beane, between Port Hill 

 and Bengeo [old] church," ? . This is probably Coleman's 

 record (under P. nigra). It is just possible that this tree, now 

 about 100 ft. high, estabhshed itself naturally.— Stansteadbury, 



? (several). — Five trees, near Turnfordj Wormley, by the road- 

 side in a clump, evidently planted, $ . — Coleman's remark on 

 P. nigra aggr., " Woods, etc., frequent " (quoted in Pryor's Flora 

 of Herts as from Coleman's catalogue) should be further investi- 

 gated. It certainly does not now apply to North Herts. If 

 P. serotina Hartig was not then distinguished, Coleman may have 

 had this latter in mind. I have not found var. betulifolia in the 

 Hitchin district. 



(2) W. Suffolk. Dalham, ? . (Det. C. E. Moss, see B.E.C. 

 Eeport, 1912, p. 286.) 



(c) VAR. viRiDis Lindley. 



(1) Herts. One tree, ? , evidently planted, by the roadside 

 about halfway between Great Wymondley and Willian. Felled 

 1916. This is the only tree of P. nigra that I have succeeded in 

 finding within a radius of ten miles of Hitchin." 



(2) West Suffolk. Windolf's Farm, Stansfield. Two trees, 

 probably planted (? S)- (Det. C. E. Moss.) 



"^'P. DELTOIDEA X NIGRA VAR. BETULIFOLIA C. E. MoSS ; 



P. LLOYDii Henry. 



(1) Herts. The ford at Ickleford, ^ , about six trees. (Det. 

 C. E. Moss. See Watson Bot. Exch. Club Report, 1912-13, 

 p. 409.) Also on Cadwell Green and in adjoining m_eadow. — One 

 tree, obviously planted, outside S.E. corner of Tingley Wood.''' 



(2) Beds. One or two trees above Cadwell Bridge, and one on 

 right bank of Hiz, opposite Cadwell (Ickleford) Common, all <$ . 

 (See B.E.C. Report, 1912, p. 287.) 



"P. DELTOIDEA X NIGRA VAR. GENUINA. 



A. X P. SEROTINA C. E. Moss, J = "^'-P- serotiua Hartig. 



Herts. Planted all over the county. Its quick growth and 

 straight stem make the timber of more value than that of P. nigra. 

 Locally the Black Italian Poplar is used at Luton for making 

 hat-blocks {fide Mr. J. H. Barker, Hitchin). Mr. A. Jacklin 

 (Royston) used a considerable quantity in repairs to machinery 

 in Mr. H. Smith's flour-mills at Royston. Mr. R. A. Saunders 

 (coachbuilder) considers the poplar a tree much undervalued. He 

 has in his yard Black Italian Poplar from Hexton Park which 

 be employs in parts of carriage bodies. Before staining and 



* Mr. A. Bruce Jackson inspected the Tingley Wood tree with me on 

 July 15th, 1916. He considers that it falls under true P. nifjra, and if so must 

 be var. viridis. On my herbarium specimen I had noted" very near F. nigra.'' 

 Mr. Jackson also pointed out to me one tree in a row of P. serotina at Grove 

 Mill, Hitchin, which he named as P. nigra var. viridis.
