The Cytology of the Cricket Bat Willow (Salix Alba Var. Caerulea). Wilkinson, J. abstract bibtex [From Introduction]: The difficulties which confront the grower of timber suitable for the manufacture of cricket bats have been clearly set forth by Burtt Davy (1932). It appears to be generally agreed that Salix alba var. caerulea Sm. (the close-bark or blue willow) furnishes the best quality of bat timber, though usable clefts can be obtained from the wood of S. alba L., S. fragilis L., and from various hybrids between them. S. fragilis yields timber of inferior quality except perhaps from the basal region of the trunk. Whilst S. alba and some of the alba-fragilis (viridis Fries.) hybrids are better in this respect, S. alba var. caerulea is far superior to any. Burtt Davy in a critical systematic study of S. alba var. caerulea has found that the tree displays a pyramidal habit consequent upon rapid and vigorous growth. The individuals recognized with certainty as being var. caerulea are all female, though Burtt Davy claims to have found males. In the female form the stems are straight, the branching is developed in an upright manner, and the bark is close. The peduncles and catkins are short, the bracteoles are also short and rounded, and the carpels possess no definite style. The question whether these features may be regarded as characters with a varietal value or merely as expressions of physiological differences is not beyond dispute, though the evidence supports the former view: That the development of an upright form is not due to overcrowding is abundantly demonstrated, as Burtt Davy points out, by an examination of typical specimens growing in open hedgerows in Essex and East Anglia, where such conditions prevail as would not discourage the tree from taking on a lax and spreading habit. Shoots from a specimen of S. caerulea planted in widely separate localities and on different types of soil also produce trees which remain pyramidal in habit at least up to the age of fifteen years. S. alba var. caerulea appears to differ from S. alba principally in the upright habit and rapidity of growth, though some maintain that glabrescence of the under surface of the caerulea leaf is also typical.
