LORD BUTE AND JOHN MILLER 87 



(1760), for which he engraved most of the plates (from 1755 to 

 1760), seventy-five of which he drew. The earher of these are 

 signed "J. S. Miller" hut on and after t. 133 (1757) "J. 

 Miller " is substituted. Miller also illustrated Hunter's edition of 

 Evelyn's Sylva (1776) in which, as the preface states, he showed 

 " great elegance and correctness as a draughtsman and engraver "; 

 he also drew and engraved some of the plates in Stillingfleet's 

 Observations on Grasses (1759). 



Little seems to be known of John Miller's life in London. He 

 w^as evidently on terms of intimacy with the botanists of his time: 

 an autograph letter in the Department of Botany (1778) acquaints 

 Dryander of the arrival of Dr. Eotherham from Upsal, with a 

 letter from Linnaeus ; another, of the same year, invites Dryander 

 and Thunberg to dinner " at tw'O of the clock." 



James Britten. 



SHOBT NOTES. 



Potamogeton Drucei (p. 37). — At the date given by Mr. 

 Marshall [i, e. in 1899) it is true that Mr. Fryer considered this 

 " a valid species," but after careful watching of its growth his 

 matured opinion w^as (June 9th, 1907) " P. lucens x 2:)olygonifolius " ; 

 Mr. Fryer first queried it as " P. fluitans " (1893). In his Flora of 

 Berks Mr. Druce suggested "P. 7iatans x alpimis " ; in the Exch. 

 Club Report for 1897, p. 568 (1898) he suggests " P. a/^zVms x 

 natans, or P. alpi7iusxpolygonifolms." Graebner {Das Pflan- 

 zenreich, IV, xi, 65 (1907) ) makes it a species, placing it between 

 P.indicus Eoxb., and P . 'polygonifolms Pourr. ; he remarks: " Eine 

 sehr ahnliche Pflanze sammelte Nolte in Trave und Eider in 

 Schleswig-Holstein " ; and in a note says, " Planta P. pulchro 

 americano valde similis sed folia submersa non crispata." To this 

 I do not agree ; my five series of Tuckerman's plant denies this 

 similarity. He also notes that Mr. Druce had distributed it in 

 Dorfler's Herb. Norm., n. 4593. On p. 133 he gives it as " P. 

 alpimis X 7iatans ?" This hybrid is also given by Neuman, 

 Sveriges Flora, p. 791 (1901), and by Kupffer, Korresp. Nat. Ver. Biga, 

 xhx, 169 (1906), as found in " Oberflusse bei Age, 1805, Bait. Prov., 

 Russia " ; also by Fischer in Ber. Bayer Bot. Ges. xi, 61 (1907). 

 Ascherson and Graebner in Syn. Mitteleurop. FL, ed. 2, i, 507 (1913) 

 still call it " P. natans x alpimis ?." My own opinion concurs with 

 Mr. Fryer's, as I could never get it to produce the colour of P. 

 alpimis after repeated attempts. Still, it does produce apparently 

 perfect fruit in cultivation occasionally, but neither Mr. Fryer or 

 myself succeeded in growing it from the fruit. — A. Bennett. 



Nos. 44 and 182 by Houstoun. Plate 272 {Helonias bullata) is signed "J. 

 Bartram " ; the drawing is stated in the text to have been " made in the 

 country where it naturally grows, by Mr. John Bartram junior"; probably 

 AVilliam Bartram, whose draughtsmanship is well known, was intended. The 

 principal engraver, apart from Miller, was T. Jeffereys or Jeffries, whose name 

 appears on most of the plates up to 115 ; five (3-5, 44, 57) are signed by Mynde, 

 The draughtsman of some of the earlier plates is not stated ; thus 248-9, 51, 

 though without name, are almost certainly by Miller.
