124 THE LIFE AND WORK OF GEORGE DON. 
had been previously gathered, and possibly A/chemilla argentea, 
so that eight of the doubted plants have been verified. 
2. The second group consists of nine plants of casual occurrence, 
which there is no valid reason to doubt Don having gathered, some 
of which have been found in other parts of Britain, but have no 
claims for insertion in the list of native, denizen, or colonist plants 
of Britain :— 
Rapistrum orientale, DC. | C. aromaticum, L. 
Neslia paniculata, Desv. Galium saccharatum, All. 
Hypericum  barbatum, G. spurium, L 
acq. G. cinereum, Sm 
Chzrophyllum aureum, L.| Triticum cristatum, Schreb. 
Three of these have been gathered by myself. 
3. Thirdly, there are a few species—three—which were certainly 
found by Don but which drainage or cultivation have extirpated :-— 
Crepis pulchra, L Deyeuxia neglecta, Kunth. 
Eriophorum alpinum, i (Calamagrotis stricta, Nutt.). 
The last of these I found in 1902 in Caithness. 
4. Fourthly, another group consists of those plants—thirteen in 
number—which either by Don or Smith were recorded under 
incorrect names or confused with continental species. These 
Arabis ciliata, R. Br., a form of A. hirsuta, R. Br., misnamed 
by Mackay and Smith. 
Stellaria scapigera, Willd., a monstrosity of Stellaria gram 
nea, 
Sanguisorba media, L., a form of S. officinals, L., mis-named 
by Smith. 
Galium aristatum, Sm., which is near G. erectum, Huds., and 
probably of casual occurrence, mistaken by Smith for the avistatum 
of Linnzeus. 
Centaurea intybacea, L., a form of C. Scabiosa, L. 
Erigeron uniflorus, Sm. (not L.), which is £. alpinus, L., mis- 
named by Smith. 
- Hieracium cerinthoides, L., which is H. cerinthiforme, Backh., 
misnamed by Smith. 
H. amplexicaule, L., which is almost certainly H. anghcum, Fr., 
var. amplexicaule, Bab.
