ix. Stamens 2, distinct. Capsules sessile, ovate, very dowjiy or silky. 

 Catkins somewhat compact, lateral, appearing with the leaves; their 

 scales discoloured at the eiid. Leaves between roundish- ovate and 

 oblong -lanceolate, soft, hairy and silky, often white and cottony beneath. 

 Small erect shrubs. Glaucas Borr,

20. S. arendria L. (d.owny Mountain TF.); leaves cottony and 

 sometimes also silky beneath, catkins usually naked at the base 

 rarely on lateral leafy shoots, style at length elongated bifid at 

 the apex with bipartite stigmas. — a. leaves with gray or whitish 

 wool or down on the upper-side, which sometimes falls off 

 through age leaving the dull surface of the leaf, styles always 

 elonixated, catkins leafless. E, B, t. 1809. S. Stuartiana Sm.: 

 E. B. t. 2586. S. limosa WahL — /S'*'. leaves elliptic-lanceolate, 

 very soon quite glabrous and shining above, styles usually short 

 at first, lengthening as the fruit ripens, catkins leafless (or rarely 

 on lateral leafy shoots). S. glauca Sm, : E. B. t. 1810. 



a. Highland mountains, especially those of Breadalbane and Clova. 

 Tj. 6, 7. — It is almost impossible to refer the Linna^an synonyms 

 to these plants, without some objections being started. Our var. a. 

 is certainly the S, arenaria L.; but that name was given in consequence 

 of Linnaeus confusing with it ^S*. fusca var. (,, which alone merited it. 

 The S. arenaria Sm. appears to be the S, Lapponum L., as to the 

 synonym of tlie Flor, Lapponica (where he says folia snbtns crassis- 

 simo vellere alho tecta) and perhaps of the first edition of the Flor, 

 Suecica, but not that of the second, where S. sericea Vill. is described; 

 and this last, according to Smith, is the S, Lappo?ium o? the Linna?an 

 herbarium: again, S, Stuartiana Sm. seems to be the state of S, 

 arenaria, of which a leaf is figured in the Flor, Lapponica, The 

 variety a. varies much in the foliage : we have collected specimens 

 m the Clova mountains with some leaves roundish-obovate and slightly 

 cordate, and others elliptic-oblong: this we suspect to be the S, lanata 

 of G. Don, the leaves being more white and woolly than usual on both 

 sides. S. arenaria Sm. is said to have the leaves ovate, acute, and only 

 shghtly downy above, while in S, Stuartiaiia they are sometimesnarrow 

 oblong-lanceolate and very shaggy above ; but these are extremes ; 

 and there is a complete transition in the form of the leaves and pubes- 

 cence, the latter not always becoming denser as the leaves are 

 narrower : we do not therefore distinguish them. .For our var. p. we 

 gwe no stations, because we have no reason to believe it indigenous, 

 Mr. Don's specimens now before us from the Clova mountains being 

 the same as var. a., and belonging to S. arenaria E. Bot. ; it is com- 

 monly cultivated, being a handsome plant, and is common in Switzer- 

 land (where we believe our var. a. does not occur), but is not, so far 

 as we know, found either in Sweden or Lapland: it has more preten- 

 sions to be called a distinct species than most others of the genus. 

 A^rom this, S. sericea Vill. {S. Lapponum Linn., at least in part, and 



T- ^r f ^^^ ^^""^^^ ^"^^ German Botanists, and perhaps also of 



_inn 1^1. Lapp., but apparently not of his herbarium) differs by the 



partite styles, and total want of cottony down on the leaves, the
