528 MR. С. BUCKNALL : А REVISION 
Mr. Hales tells me that there is no record of the origin of the present. Chelsea 
plant, but from the length of time that species of Symphytum are known to 
persist in this country, it seems probable that it is a descendant of the original 
plants. There is a specimen at Kew, gathered at Chelsea in 1849, which is 
probably of the same stock. 
On Don's figure of this plant, De Candolle founded a new species, 
which he described in the * Prodromus? as S. Donii. The ealyx-teeth in the 
figure are subulate, acuminate, almost equal to the tube, and in this it differs, 
as De Candolle says, from 5. caucasicum. But in the description accom- 
panying the figure the calyx is described as “ 5-angled tubular... . with 
9 ovate, blunt, connivent teeth," which accurately represents that of 
©, caucasicum. In the figure, moreover, the calyx is drawn so narrow that 
there would not be room for the enclosed organs, and this, together with the 
limb of the corolla suddenly bulging out beyond the calyx-teeth, makes the 
flower unlike that of any species of Symphytum. This excepted, there is 
nothing in the drawing which separates it from 5, caucasicum, and the 
description of the corolla-scales, * ligulate, blunt,” exactly fits those of that 
species. There is no known specimen of S. Donii, and no botanist appears to 
have even seen one, although the name has occasionally been suggested for 
other species. It is clear, therefore, that S. Donii, being founded on an 
erroneous drawing, does not exist as a species. 
The type specimen of var. glabriusculum in Herb. DC. has a much branched 
stem, with narrow decurrent leaves, and is thinly clothed with scattered 
hairs. Mr. G. C. Druce’s Oxfordshire plants and other narrow-leaved forms 
may perhaps belong to this variety.
