242 ANNALS OF SCOTTISH NATURAL HISTORY 



Tilia ulmifolia, Scop. I use this name because Mr. 

 E. G. Baker (" Journ. Bot.," p. 319, 1898) says, that Miller's 

 type cordata is platyphyllos, and he considers the description 

 (" Gard. Diet," No. I, 1768) answers better for platyphyllos 

 than ulmifolius. I hesitated to use T. cordata for platyphyllos 

 on account of the confusion which must arise when a name 

 is transferred from one species to another ; for that reason 

 I have retained Melilotus officinalis for M. altissima, Thuill., 

 and not for M. arvensis (Petitpierreana), since in " Journ. 

 Bot." ( i 887, p. i 8 i), J7. officinalis, Lam., was made to replace 

 M. altissima, Thuill. The " Index Kewensis " evades the 

 difficulty by making the two species of Melilot synonymous. 

 Eventually, if it is proved beyond doubt that M. arvensis = 

 officinalis and Tilia cordata = T. platyphyllos, we may have to 

 use the names in this sense. 



Medicago lupulina, L., var. Willdenowiana, Koch, is the 

 correct name. Var. scabra, Gray ("Nat. Arr." ii. p. 605, 

 1821), has " legumen slightly compressed, rough with many 

 tubercles " ; there is no mention of glandular hairs. This 

 might be added as var. c, scabra, Gray, to my List.
