polishing, the surface is filled up with a saccharine solution 

 (Powellizing). 



B. ■'' X P. CANADENSIS C. E. Moss, $ = P. Canadensis Moench. 

 Herts. Planted, Avenue Lodge, The Avenue, Hitchin. The 



tree was growing into a very fine specimen, but has now (1916) 

 been severely lopped. (See Watson E.G. Report, 1914-15, p. 509.) 



C. A tree which appears to belong to the series P. deltoidea 

 X nigra, but is neither A nor B. (Herb. J. E. Little, Ref. No. 101.) 



West Suffolk. Planted along watercourses between Denston 

 and Wickham brook, and near Badmondisfield Hall, and abun- 

 dantly in the valley of the Stour between Clare and Haverhill. 

 Leaves smaller and of thinner texture than in P. serotma, more 

 of the average size of P. italica, but with two, one, or no glands 

 at base of midrib, and in spring of a pale green colour which 

 contrasts strongly with the coppery colour of P. serotma at the 

 same time. Faint pubescence, quickly vanishing, on petiole and 

 lamina. (See Watson E.G. Report, 1912-13, p. 408.) In May, 

 1912, travelhng by train from Glare to Haverhill, I could pick 

 this tree out from P. serotina by the foliage. Many of the trees 

 are treated in the French fashion, being lopped of side branches 

 sometimes for three-quarters of their height.

(1) Herts. Plantation at The Node, Godicote. Plantation 

 between Pottersheath and Sisserferns Farm, Godicote. Planted 

 and fenced in by Mr. M. R. Pryor in a field nearly opposite the 

 P. alba avenue at Weston Park, Stevenage. 



(2) West Suffolk. A large tree in the spinney along the stream 

 between Poslingford and Wentford. 



(3) West Sussex v.c. 13. A number of trees near Fishbourne 

 Ghurch. 



Summanj. Mr. Marlborough R. Pryor, of Weston Park, 

 considers P. tremula our only native poplar in North Herts. 

 Dr. B. D. Jackson, editing A. R. Pryor's Flora of Herts, ad- 

 mitted P. alba and P. canescens as native. Dr. G. E. Moss's 

 nvestigations have since excluded P. alba. 1 have suggested that 

 P. canescens is not native in North Herts. In the lower valley 

 of the Lea it is possible that P. nigra may be native, but more 

 and recent records are desirable.

LXV. — Heney Andrews and his "Botanists' Repository." 



In this Journal for 1886 (p. 297, footnote) I expressed an 

 intention of publishing later some notes on the authorship of 

 Andrews's Botanists' Beioository. I had hoped that in course of 

 time I should succeed in obtaining full light upon the subject, but
