494 MR. C, BUCKNALL: A REVISI ON 
There is in the S. tuberosum cover in Herb. Linn. a glabrous narrow-leaved 
plant belonging to the group of S. officinale, marked on the back of the 
sheet “S. vulgare, Gmelin,” but with no other indication of its origin. 
In Smith's herbarium there їѕ a similar specimen. This plant was described 
by Kerner in 1863, from Hungarian specimens, as S. uliginosum. It has 
been found, doubtless as an introduced plant, at Sefton Park, Liverpool. 
S. tuberosum, Ucria, Hort. Reg. Pan. (1789), non Linn., is quoted by 
Gussone as 8. Zeyheri, Schimp. This was recorded by Gussone in Prod. FI. 
Sic. (1827) as S. bulbosum ; it was, however, separated from that species 
by Schimper in 1829. 
S. tauricum was described by Willdenow in 1799, and hy Hornemann 
(as S. bullatum) in 1813. When introduced. into England it became known 
by both these names, and was figured in the Botanical Magazine in 1816. 
S. cordatum, Waldst. & Kit., was also described in 1799, and b 'autifully 
figured in the authors’ * Deseriptiones Plantarum rariorum Hungarie? in 
1802. It was again described by Persoon in 1805 as ©. pannonicum, 
and by Baumgarten in 1816 as S. eordifolium. 
The name S. cordatum was likewise used by Marschall von Bieberstein, 
in 1808, for a nearly allied but very distinct plant, S. grandiflorum, DC. 
This was discovered by Steven in Imeritia in 1805, and named by him 
S. ibericum, but it does not appear that he published the name until 1819, 
or the description until 1851. In the meantime De Candolle, in the 
‘ Prodromus? (1846), described it from specimens sent by Wilhelms from 
Iberia (Province of Tiflis), as S. grandiflorum, and this name therefore has 
priority. I have seen living plants of this species, unnamed, in the botanic 
gardens of Cambridge, Bristol, and Geneva. 
S. caucasicum was described by Marschall von Bieberstein in 1808, and 
as S. raeemosum by Roemer & Schultes in 1819. Tt was introduced into 
Britain in 1830, and is occasionally found seminaturalised or as an escape. 
S. ottomanum was described by Frivaldszky in 1836. 
S. palestinum was described by Boissier in the * Diagnoses’ in 1844, but 
specimens exist which were collected by Guillardot in the Antilibanon in 
1817, and by Aucher-Eloy in the neighbourhood of the Taurus in 1837. 
Some of these have since been named S. orientale B. angustior, DC., but they 
are quite distinct from any form of S. orientale. Others have been referred 
to S. esperrimum and S. anatolicum. 
S. peregrinum was described by Ledebour (Ind. Sem. Hort. Dorp., 1820), 
presumably from plants from the province of Talysch in the extreme south- 
east of the Caucasus. Specimens exist which were grown in the Geneva 
Botanic Gardens between 1820 and 1830, and this species was subsequently 
introduced into Britain and Seandinavia as a fodder-plant. It is now 
extensively naturalised in these and other countries, and has even been 
cultivated with more or less success in India and Australia (see Report on
