OF THE GENUS SYMPHYTUM. 545 
Voden, Macedonia, Adamovic, 1903. Herb. Kew.—S. tuberosum. Camal- 
doli, Naples. М. Guadano, 1904. Herb. Bicknell.—Vergers entre Locarno 
et Minusio, Tessin. Herb. Kew. 
The creeping root, simple stem, and exserted corolla-scales clearly separate 
this species from all others except S. Zeyheri, and from this it is distinguished 
by the smaller basal leaves, which are less abruptly contracted into the 
petiole, and by the rather smaller corolla. The root is very slender and far 
creeping—in Bischoff’s figure it is 4:5 dem. long—unbranched, with a few 
rootlets at the base of the stem and on the tubercles. The leaves are more 
often rounded at the base than in S. tuberosum, but are sometimes gradually 
attenuated into the petiole. 
De Candolle states that a Swiss specimen in his possession has small 
flowers with the corolla-scales and style scarcely exceeding the corolla, but 
that it must undoubtedly be referred to this species. The plant from 
Solduno, Locarno, has similar flowers. In the olive groves on the Italian 
Riviera S. bulbosum grows to a large size; in Mr. C. Bicknell’s herbarium 
there are plants with leaves measuring 17 em. long and 9 em. broad. 
Schimper’s description is taken from plants growing in the vineyards at 
Heidelberg. If S. bulbosum is native here, this must be the most northerly 
extension of its area.
