358 MR. C. E. SALMON ON 
Since the above was written, Mr. Britten kindly examined this specimen 
and reported that after the words “S. intermedia” on the sheet, some 
writing I could not decipher was certainly * MSS.", and that this refers to 
the Solander MSS. in which the description is found and upon which 
* Hortus Kewensis," ed. 1, was based. Mr. Britten added this interesting 
note :—* The name on the sheet and the description in the MSS. (vol. xiii. 
p. 67) are entirely in Solander’s hand, so that if you like, you can cite the 
plant as of [Solander in] Aiton, Hort. Kew. ii. 301. 
“ Solander, in his MSS., added, later than the description, * 1764 in Carolina. 
Catesby. Consequently I hunted up Catesby’s plants and in Herb. Sloane 
212, f. 29, I found his specimen, also named by Solander .... Whatever 
this may prove to be, the Kew Gardens plant is the type of S. intermedia as 
the reference to Catesby was added later.” 
I have looked at this American plant and believe that it is a broad-leaved 
form of Stachys palustris, a frequent species in the Southern States, whereas 
S. germanica and alpina are unknown there. 
I presume that the plant that occurred in my garden used to be in cultiva- 
tion at Kew, as it is included in the Kew Handlist of Herbaceous Plants, 
ed. 1, p. 445, 1895 (as S. alpina, L., var. intermedia), but it has apparently 
died out and is not mentioned in the 1902 (2nd) edition. I cannot find the 
plant included in any of our nurserymen's catalogues that I have come 
across, nor have I seen it in any gardens with which I am acquainted. 
Nothing is known of it at the Cambridge Botanie Garden. 
On the Continent, however, where the two parents are more widely and 
abundantly distributed under natural conditions, the hybrid is apparently 
of quite frequent occurrence in gardens. M. Rouy states that it is often 
cultivated in gardens (Fl. Fr. xi. p. 308, 1909), and M. Correvon, the well- 
known hortieulturist of Chéne-Bourg, Geneva, writes :—* They all cross 
very often even in nature. We have in Switzerland alpino-lanata and 
alpino-germanica." 
Briquet has an interesting note, under S. alpina in his * Labices des Alpes 
Marit.” par. 2. 240, 1893, where he mentions that it crosses particularly 
readily with S. germanica, giving rise to a series of intermediate plants, 
usually sterile, of which many are cultivated in gardens on account of their 
beautiful spikes of flowers and velvety foliage. 
He mentions the various names that have been given to these hybrids, and 
remarks that although no specimens have yet been found in his distriet in 
a wild state, it is quite likely to occur, as the parents are both found. 
He explains Bentham’s remark in DC. Prodr. xii. 465 : “J see no definite 
limit between S. germanica, S. lanata, and . . . . S. alpina," owing to the 
fact that that author recognized no hybrids in the genus Stachys. 
Rouy (I. c.) has attempted to segregate the hybrid accordingly as it varies 
towards one parent or the other, using the name /ntermedius, Ait., for the 
aggregate plant, with synonyms S. sibirica, Link, and S. rosea, Hohen,
