Sonder quite correctly followed Willdenow (1799) in uniting 
D. incurvus, Thunb. (1794) with D. albens, Ait. (1789), but in 
doing so’ he should not have restored Thunberg’s name, rightly 
treated as a synonym by Willdenow. Thunberg himself accepted 
Aiton’s name in preference to his own in his herbarium, where 
he has written “‘ D. albens, Wild.” in the lower right-hand corner 
_ where he usually labelled his specimens, while in the lower left- 
hand corner is written, also in his own handwriting, the synonym 
“'D. incurvus, Prod. cap.”’+ But as the name Dianthus incurvus, 
Thunb. has been familiar to students of South African botany 
for over sixty years, through the pages of the Flora Capensis, 
no good purpose would be served by restoring Aiton’s name. 
There is but one specimen ‘labelled D. incurvus, in the 
Thunberg herbarium, and it does not agree with Thunberg’s 
description of that species, for the petals are lacerate, not 
‘“integris ’t, and the cauline leaves are linear, up to 4°5 mm. 
road, not at all ‘“ lineari-setacea’’. At the back of the sheet 
is written in the upper left-hand corner (the place where he 
usually noted the localities of his specimens) “‘e Cap. b. Spei. 
Thunberg ’’; but the specimen does not match any South African 
material at Kew or the British Museum; it appears to be some- 
what abnormal, suggesting a cultivated plant, and may be a 
garden specimen of some extra-South African species. It is 
clear that the sheet was labelled later than the publication of 
Thunberg’s Prodromus, for he cites Willdenow for the name 
albens, and the second volume of Willdenow’s edition of the 
Species Plantarum, in which Aiton’s name D. albens is used, was 
not published until 1799. 
We must conclude therefore, that the specimen labelled 
D. incurvus in the Thunberg herbarium, is not the original type 
from which Thunberg drew his description. 
Prof. Juel’s suggestion that the description of D. incurvus may 
have been made while Thunberg was in South Africa, and there- 
fore from living material, seems a probable explanation, especially

ginate to crenate or dentate, but are not lacerate.
