APPENDIX B.—DISCOVERIES. 127 
Lepidium heterophyllum, Gevth., var. canescens, Gren. and 
Godr. (Thlaspi hirtum, Sm. not L.), L. Smithit, Hook. 
“ Thlaspi hirtum. In 1800 Mr. J. Mackay sent me the true 
plant from Perthshire found by Mr. J. Miller ; and the following 
year I received a variety with smooth fruit, gathered i in we 
shire and Angusshire by Mr. G. Don.” Smith in Eng. Bot., t. 
1803 (1807). In Herb. Sowerby, Don has written on a label 
attached to specimen, “ Thlaspi I call this zzcana, but as most 
of the genus are named from the places where they grow, | 
believe it would be better to call this pratense, as it is found 
only in meadows by the sides of rivers. It differs from the 
Seieises in the form of the silicula and the largeness of the 
corolla, and in the stalks inclining to the ground in manner of 
irtum—it is a biennial. I sent you a specimen of this before, 
supposing it the Azrtum, but since I have got the true hirtum of 
inn. Mr. Miller, gardener to the Earl of Kinnoul, was the 
first to take notice of this plant above 20 years ago; he found it 
in meadows in Strathearn, and I found it hala Bricken and 
Montrose in Angusshire growing by the river Esk’s side, but 
never found it in any part else by the rivers Esk and Earn. | 
believe this to be a nondescript.” 
The above note will aed how clear Don was in his recog- 
nition of new forms. It was Sir James E. Smith who confused 
two different plants in English aie under the above name.
