À HYBRID STACHYs. 359 
The form which approaches the germanica parent he called “ a. digeneus 
nob.", founded upon the S. digenea, Legué (in Bull. Soc. Bot. Fr. xl. p. 213, 
1893), and to this he assigned the synonyms S. germanica var. intermedia, 
Boiss., and S. curviflora, Tausch. 
The form which has more affinity with S. alpina, Rouy called “8. para- 
doaus nob.", which he considered synonymous with S. alpina var. intermedia, 
Benth., and, doubtfully, S. urticifolia, Tausch. 
If we follow Rouy, my plant must be placed under his a. digeneus, as 
it possesses a preponderance of the characters of germanica and agrees 
satisfactorily with M. Legué's original description (l. c.). 
As regards the synonyms mentioned by the authors quoted above, the 
following notes were made when endeavouring to work out my specimens at 
the British Museum. 
S. sibirica, Link.—This is described in Enum. Hort. Bot. Berol. pars 2, 
p. 109 (1822), and from the description it is possible it may refer to the 
hybrid under discussion, but if the figure in Sweet, Brit. Fl. Garden, i. t. 100 
(1825) correctly portrays Link's plant (and it is so labelled), then that is a 
form with remote whorls of flowers even at the summit of the stem, and the 
clothing of the plant less silky in nature than in my specimens. 
Reichenbach’s Ic. Crit. iv. t. 328 also figures the S. sibirica of Link, but 
that again differs from my plant in many respects, which tallies far better 
with t. 327 in the same work, labeled S. intermedia, Ait. 
S. rosea, Hohen.— Boissier (Fl. Orientalis, iv. 720, 1879) gives this as one 
of the synonyms of his S. germanica var. intermedia, and indicates that he 
has seen a type-specimen. It must not be confused with the S. rosea of the 
latter author (op. cit. 725). Hohenacker's description (Enum. Talysch, 300, 
1838) is meagre in the extreme, practically a “nomen nudum," and I have 
not been able to see any specimens. 
S. alpina, L., var. intermedia, Bentham in DC. Prodr. xii. p. 465 (1848). 
This has a short description—*' major, foliis rugosioribus subtus interdum 
sublanatis," and a large number of synonyms. We cannot, I think, 
conclude as Rouy has done, that because the * variety " is placed under 
alpina it indicates a form of the hybrid that approaches more to that parent. 
Indeed, Bentham adds—** An ad S. germanicam melius referenda ?? 
Of the synonyms he gives, two strike me as being remarkable— 
“ S. cretica, Linn. spec. p. 812, fide deseriptionis. S. orientalis, Linn. spec. 
p. 813, fide exempl. Tournef. in h. Banks.” 
As regards the former, Index Kewensis (ii. 972, 1895) indicates that 
S. cretica, L., Sp. pl. 581 (the Bentham synonym refers to ed. 2 of Sp. pl.) 
equals * germanica, alpina”: the Linnean description, however, will not do 
at all for the hybrid under discussion, but seems to correspond with the fine 
figure in Sibthorp, Fl. Grzeca, vi. t. 558 (1827) labelled S. cretica.
