LIQUIDAMBAR ORIENTALIS 



mr. knight's note (Vol. IV. p. 161, 1932) to the effect 

 that he had been successful in striking cuttings of this ex- 

 tremely rare tree interested me very much. I was de- 

 lighted to find recently that similar success had attended 

 the efforts of Mr. Wallis, the head-gardener at Woburn, 

 who, some considerable time before Mr. Knight's note ap- 

 peared in print, had obtained rooted cuttings and layers 

 from the old tree at Woburn, described by me [New Flora 

 and Silva, Vol. I. p. 173, 1929), to root after others had 

 failed. Apparently this is not a very difficult matter if good 

 half-ripened wood taken between July and September, 

 according to the season, is used. 



The method employed at Woburn is to take pieces 

 about four inches in length, the base of the cutting being 

 as near the old wood as possible; insert them in a pot which 

 is placed under a bell-glass. In a comparatively short time 

 the cuttings root freely. One cutting rooted in 1930 is now 

 a vigorous plant 2J feet high, which will be put out shortly. 



Another but much slower method of propagation is to 

 insert the ends of the cuttings in a bottle of water, the neck 

 of the bottle being packed with moss. After about three 

 months of this treatment the cuttings begin to show signs of 

 rooting. Layers were obtained by pegging down some of 

 the branches from near the base of the bole.
