SALIC ACE AE. — SALIX 139 



Salix, sect. Myrtosalix Kernerin Verh. Zool.-Bot. Ges. Wien. X. 203 (Niederoest. 

 Weid.) (1860). — Seemen in Ascherson & Graebner, Syn. Mitldeur. Fl. IV. 

 161 (1909). 



A sect. Diplodidyae praecipue recedit foliis utrinque viridibus et reticulatis, 

 Baepe serratis, floribus cf glandula tantiim ventrali instructis. 



In my III. Handb. Laubholzk. (I. 41 [1904]) I referred S. arctica Pallas (see p. 

 136), which is placed by Koehne (Deutsche Dendr. 95 [1903]) and by von Seemen 

 (1909) in the sect. Myrtosalix, to the section where S. glauca Linnaeus belongs (see 

 p. 147). In S. arctica Pallas I have found stomata in the upper surface of the 

 leaves, as did Camus (Classif. Said. d'Europe, II. 54 [1905]). Camus keeps S. 

 arctica Pallas with S. Myrsinites Linnaeus in the sect. Myrtosalix, but 1 cannot 

 accept his rather artificial classification based on anatomical characters. Only a 

 comparative study of all the existing Willows with regard to every character pre- 

 sented by the sexual and vegetative organs can lead us to a natural arrangement. 

 If there are only a few stomata in the upper surface of the leaves, this character 

 does not seem to be very useful. I add S. polaris Wahlenberg to this section because 

 this species agrees very well with S. Mijrsinites Linnaeus in the structure of the cf 

 and 9 flowers and in the color and reticulation of the leaves. The position of S. 

 microphyta Franchet is still doubtful.

NORTHEASTERN ASIA. Maritime Prov. and Kamtchatka (ex 

 Herder). 



I have not seen any specimen of this species from our area. It is a very variable 

 species, and a prostrate or somewhat erect much branched low shrub. The leaves 

 are shining green, and vary from orbicular-oval to narrow-lanceolate. The petioles 

 are only from 1 to 5 mm. long. The catkins resemble those of S. arctica Pallas and 

 are very silky when they first appear.

NORTHERN ASIA. Yakutsk: Arakam Island, 1853-6, C. Wright. 



The proper position of this species is uncertain. Most authors include it in the 

 sect. Herbaceae, and Andersson even says, 1. c. (1868): "S. herbaceae ita similis, ut 

 ab ea vix distinguatur." In my Laubholzkunde, 1. c, I stated, that I had never 

 seen a c? flower with a dorsal gland which seems to be always present in S. herbacea 

 Linnaeus. In habit S. polaris is diflercnt from S. Myrsinites Linnaeus, but other- 

 wise, I do not see any difficulty in placing it in the same section. In Wright's 

 specimen the 9 flowers sometimes have a small dorsal gland and the length of the 

 pedicel and style is very variable.
