Concerning S. orientalis, here again Ind. Kew. (op. cit. 973) refers the 
Linnean plant to “alpina” ; neither the description nor the plate in Sibthorp 
(op. eit. t. 560) of S. orientalis bears this out. Moreover, the Tournefortian 
example in Herb. Mus. Brit., quoted by Bentham, is clearly not of close 
relationship with germanica, alpina, or intermedia. 
S. germanica, L., var. intermedia, Boiss.—I think it is clear from the 
description given (loc. cit.) that Boissier would include under his name that 
form of the hybrid which shows more obviously the germanica parent. 
It might be possible to arrange the rather puzzling synonymy of the 
hybrid and the varying forms as follows :— 
The * aggregate " hybrid : 
S. sibirica, Link (1822). 
S. alpina, L., var. intermedia, Benth. (1848). : 
S. alpina x germanica, Briq. (1893). 
* Regregate " A h 
(nearer germanica). J S. intermedia, Sol. in Ait. (1789) *, 
S. curviflora, Tausch (1831) (fide Rouy). 
S. rosea, Hohen. (1838). non Boiss. 
S. germanica, L., var. intermedia, Boiss. (1879). 
S. digenea, Legué (1893). 
S. intermedius, Ait., var. digeneus, Rouy (1909). 
* Begregate ” B \ 
(nearer alpina). S. paradoxa, Rouy (1893). 
? S. urticifolia, Tausch (1831). 
S. intermedius, Ait., var. paradoxus, Rouy (1909). 
It may perhaps be of interest to record in tabular form the characteristics 
of my hybrid as eompared with the corresponding features of S. germanica 
and S. alpina, observed from growing and dried material :— 
S. germanica. 5S. digenea. S. alpina.
