C. (Ederi is cited by Smith (p. 107) as of Ehrh. Calam. 79 : this 

 is hardly a publication, and the name to be retained for the species 

 is doubtful. 



IV, Plant.e ciiYPTOGAM.E L. (32 fascicles) [17S5-1793]. An 

 index of fasc. 1-24 of these (dated Oct. 1791) — "quas in Locis earum 

 natalibus collegit et exsiccavit Eridericus Ehrhart " — is given in 

 13eitr. vii. 94-102, with an intimation that the conclusion would 

 follow ; but no f ui-ther part of the Beitrlif/e appeared. The lichens 

 of these decades and of the Pliytophi/laciiim and FJantce officinales 

 are enumerated but not identified by Bernt Lynge {Index " Lichenitm 

 J^xsiccatonan,'' i. 1(51-104 (1915). As has already been said (p. 323), 

 the contents of the decades are incor})orated in the cryptogamic 

 ])ortion of the National Herbarium. Eries in the paper already cited 

 states that decades 1 and 2 were issued in 1785; 3 and 4 in 1786; 

 5 and 6 in 1787 ; 7 to 10 in 1788; 11 to 10 in 1789; the dates of 

 the remainder were unknown to him. 



V. AE130RES, TKUTICES ET SUFFKUTICES L. [1787-1793] — " quos 



in Usum Dendrophilorum collegit et exsiccavit Eredericus Ehrhart." 

 An " index " of twelve fascicles — the first of which was issued in 

 1787 — dated " Herrenhausen, Nov. 1789 " is given in Eeitr. v. 158- 

 1()2 : the remaining four must have been issued between that year and 

 1793. This series is frequently cited in Beitr. vi. and vii. (see p. 324), 

 and the specimens are typical for such of the species as were described 

 by Ehrhart. 



Yl. Herb.e L. [1787-1793] — " quas in locis earum natalibus 

 collegit et exsiccavit Eridericus Ehrhart " : an " index " of twelve of 

 the decades is in Beitr. v. 175-179 : Names from this are cited in 

 Beitr. vi. 143-4, vii. 153, 156. 



VII. Plants selects hortuli proprii [1792-1793]. Of the 

 sixteen decades that were issued in this series, no enumeration was 

 ])ublished by Ehrhart, but some of the plants are cited as " Ehrh. 

 Sel.," though always without number, in his " Bestinnnungen einiger 

 Pfianzen meines Gartchens" (Beitr. vii. 139-168). The absence of 

 number is curious, as the series was numbered like the rest, and in 

 the case of all the other Exsiccatie the number is always cited 

 by Ehrhart. Of these fascicles, eight were ready by the end of 1792, 

 and the remainder were issued in the following year. 



This notice has extended to much greater length than I had 

 anticipated when it was begun ; I can excuse this only on account of
