SALICACEAE. — SALIX 139 
Salix, sect. Myrtosalix Kerner in Verh. Zool.-Bot. Ges. Wien. X.203 (Niederoest. 
Weid.) (1860). — Seemen in Ascherson & Graebner, Syn. Mitteleur. Fl. IV. 
161 (1909). 
A sect. Diplodictyae praecipue recedit foliis utrinque viridibus et reticulatis, 
saepe serratis, floribus c? glandula tantum ventrali instructis. 
In my Ill. 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. M: yrtosaliz, 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. Saul. d’ Europe, Il. 54 [1905]). Camus keeps S. 
arctica Pallas with S. Myrsinites Linnaeus in the sect. Myrtosaliz, 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. Myrsinites Linnaeus in the structure of the c? 
and 9 flowers and in the color and retieulation of the leaves. The position of S. 
microphyta Franchet is still doubtful.

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

The proper position of this species is uncertain. Most authors include it in the 
Sect. Herbaceae, and. Andersson even says, l. e. (1868): “S. herbaceae ita similis, ut 
ab ea vix distinguatur." In my Laubholzkunde, |. c., I stated, that I had never 
Seen a c? flower with a dorsal gland which seems to be always present in S. herbacea 
anaeus. In habit S. polaris is different from S. Myrsinites Linnaeus, but other- 
Vise, 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 
cel and style is very variable.
