198 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 



of Mr Massie, to whom the plant was sent from the south of 

 England for identification, I was able to obtain a satisfactory 

 photograph of a plant which seemed identical in its characters 

 with the Haystoun plants, and by the courtesy of the proprietors 

 of the Gardeners^ Chronicle I am able to give here a reproduc- 

 tion of the photograph, from which it will be seen that the plant 

 is quite distinct in habit from the ordinary green type of the 

 Douglas fir. In this plant the main side branches, instead of 

 spreading out horizontally, as in the ordinary green type of the 

 Douglas fir, take a more or less erect course which, coupled 

 with the short intervals between the whorls of branches, gives 

 it a bushy appearance, with a branch-habit not unlike that 

 of the Scots pine when of the same age. Regarding the 

 source from which either this or the Haystoun plants emanated 

 I can say nothing, but in both cases the leaf and bud characters 

 seem to agree closely with those of the species macroca?-pa 

 as described by Sargent in his Silva. 



By the favour of Mr Annand, who has kindly obtained the 

 particulars for incorporation in this note, I am able to give 

 here some information relating to the growth of these glaucous- 

 leaved Douglas firs at Haystoun, and of the spruce with which 

 they are associated ; and also of the plant sent to Mr Massie 

 for identification. The plants selected for measurement by 

 Mr Annand were average specimens, and they therefore give a 

 fair idea of the height-growth over the whole plantation. The 

 plantation, which is small, grows on a rather stiflf, clayey soil, 

 varying to sandy clay, and on a site which was formerly 

 occupied by a heavy crop of spruce, with a few larch and 

 silver fir intermixed. 



Both the Douglas fir and the spruce in the Haystoun planta- 

 tion are at least thirteen years old, while the English plant sent 

 to Mr Massie was at least eight years old; but owing to the 

 difficulty of accurately ascertaining the age at the lowermost 

 part of the stem, the ages given in the following Table must be 

 taken as approximate only.^ At 6 inches above the ground 



' In all three cases the age of the stem at 6 inches above the ground was 

 scertained by counting the number of annual rings, and a year was added 

 to this for the age of the plant. Possibly two years should have been added, 

 but as Mr Annand states that he has had two-year-old seedlings of the 

 Colorado variety 6 to 7 inches high, the age has been fixed on the assumption 

 that these plants were o\er 6 inches high when two years old.
