CHINA. Chili: Hsiao Wu-tai-shan, alt. 2300 m., August 12, 1913, F. N. 

 Meyer (No. 1204; shrub; sterile). 



NORTHEASTERN ASIA. Maritime prov. : Plover Bay, Lat. 64" N., 

 1865-6, W. H. Ball (with fruits). Kamtchatka: Petropavlovski, 1853-6, C. 

 Wright (with fruits). 



Franchet, 1. c, mentions specimens from Chili collected by David which I have 

 not seen and which probably do not belong to our species, and may be the same as 

 S. mongolica Siuzev (see p. 178). Burkill cites a specimen of Bretschneider from 

 the Po-hua-shan, and the species is also found in Mandshuria and Korea accord- 

 ing to Komarov and Nakai. The specimens before me collected by Dall and 

 Wright differ somewhat from the type. The ovaries are rather short-stalked, and 

 the glands are longer than the pedicels. The peduncles of the fruiting aments of 

 Dall's plant are up to 2 cm. long. They may represent S. oblongifolia Trautvetter 

 & Meyer, see p. 126. 



All these eastern forms of this section need a very careful study. Meyer's sterile 

 specimen agrees rather well with some European forms of this variable species.

^ According to the Vienna rules this name cannot stand. The type of Linnaeus 

 S. arbuscula is founded on " Salix foliis subserratis glabris subdiaphanis subtus 

 glaucis, caule suffruticoso" in Fl. Suec. 291, No. 798 (1745), var. a, and the type of 

 var. a is "Salix foliis serratis glabris verticaliter ovatis" in Fl. Lappon. 284, No. 

 352, tab. 8, fig. e (1737). This No. 352 is the same as S. livida Wahlenberg (vide 

 Enander, Salic. Linn. Herb. 97 [1907]). Linnaeus' herbarium specimen may belong 

 to »S'. phylicifolia Linnaeus or to a hybrid of <S. nigricans Smith with aS. phylicifolia 

 (see Enander, 1. c). Linnaeus' S. arbuscula, var. fi, Spec. 1018 (1753) is founded 

 on " Salix foliis integris glabris ovatis confertis pellucidis " in Fl. Lapp. 287, No. 

 356 (1757). This No. 356 represents S. livida Wahlenberg (see Enander, 1. c). 



Only S. arbuscula, var. y represents the true S. arbuscula Auctorum plurim. (see 

 Enander, 1. c. 149). So far as I can see the oldest name for this form is S. formosa 

 Willdenow. Andersson and von Seemen cite a Salix coruscans Jacquin, Fl. 

 Austr. V. t. 408 (non Willdenow) (1778). But Jacquin describes, 1. c, under No. 

 408 Salix arbuscula. It was Willdenow, Spec. IV. 681 (1805), who founded a S. 

 coruscans on S. arbuscula Jacquin. S. formosa Willdenow was published 1796, and 

 this name is older than S. glaucescens Moench, who merely changed Willdenow's 

 name. S. alpina Scopoli, Fl. Cam. ed. 2, II. 255 (1772) is a mixture of S. arbuscula 

 and S. myrsinites, var. Jacquiniana Koch.
