322 THE JOURNAL OF BOTANY 



" Agrostls pumlla L., wliicli I gathered in company wltli my late 

 friends Linnaeus and Griino near the Linnean villa, Hamniarby, and 

 which both acknowledged [? considered] to be a distinct species, is 

 nothing, according to my own observations, but a diseased Ar/ros/is 

 stolonifera. I preserve specimens which are half Agrostis sfoloui- 

 fera^ half A. pumlla " (p. 272). Koenig adds a note confirming this. 



Of Ehrhart's earlier life, we find interesting particulars in his 

 autobiographv published by Usteri, and in the obituary notice 

 by D. H. Hoppe, both mentioned above. He was born at Hol- 

 derbank in the canton of Bern on November -i, 1742, where his 

 father, Johannes Ehrhart, was pastor. Johannes frequently jnade 

 botanical excm-sions with Haller ; the young Friedrich often accom- 

 panied them, and in this way aCvn[uired a taste for botany. He com- 

 piled a Yloriila Holderhcuikensis which attracted the notice of 

 Haller, who offered the lad the post of amanuensis and librarian, 

 which he declined on account of his father's failing health. Anxious 

 to continue his botanical studies and at the same time to obtain 

 remunerative occupation, Friedrich, after his father's death, obtained 

 employment in an apothecary's sho]) in Nuremberg, where he served 

 his tliree years' apprenticeship (17G5-(58). He then went to an 

 apothecary in Erlangen, where he remained until Easter 1770; 

 during this period he made botanical excursions on foot to the Fich- 

 telberge and in Switzerland; he was afterwards employed by Andrea, 

 with whom he remained until Easter 1773. Ehrhart's intense desii-e 

 for botanical knowledge continued to increase, and nothing would 

 satisfy him but the lectures of the great Linnaeus himself; so oif he 

 went to Upsala and attended Linn^eus's lectures ; his career at this 

 period has already been summarised. 



For further details of Ehrhart's life, reference must be made to 

 the sources already indicated, to which may be added an account by 

 H. Stein worth, not seen by me, cited by Lindau and Sydow {The- 

 saurus, iii. 205) from Hannoversche Gartenzeitung, xii. (1902) ; 

 and especially t© the autobiography, from which we gather a pathetic 

 impression of the great straits to Avhich he was reduced by poverty. 

 He tells us that he and his wife, whom he married in 1780, accus- 

 tomed themselves to the severest privations in order that a few jDence 

 might be set aside for buying books; and it was with the same 

 obiect in view that he began the publication of the Exsiccated. 

 These privations, in conjunction with a phthisical tendency, doubtless 

 shortened his life ; he died at Herrenhausen on July 3rd, 1795. 



To return to the JExslccatce, Smith acquired his series of these 

 with Davall's herbarium in 1802 ; a list of these will be found among 

 the "books quoted" prefixed to his English Flora (i. xxxvi ; 1824), 

 where the titles of five are given, with reference to the Beitrdr/e for 

 their contents. Those absent are the Planted Cryptogamce and tlie 

 Flantce Selectee ; I think the latter may be indicated by the entry: 

 "PZ. Exsicc. — Planted Exsiccated. — A collection of Dried Plants, 

 published subsequently to all the foregoing, but which was not, 

 I believe, continued to any extent." This supposition would explain 

 the omission of Fl. Selectee from Smith's enumeration — an omission 

 otherwise inexplicable, as the plants themselves, with Ehrhart's
