42 DWAEF AND SLOW-GROWING CONIFERS 



slightly incurved; under side convex; upper side nearly 

 flat. 



I recently received a photograph of a very fine specimen 

 of this form growing in Mr. Walter Hunnewell's Pinetum 

 at Wellesley, Mass. There it has made a dense pyramidal 

 bush about 4 feet high by as much through. This is by 

 far the best specimen that I have seen. It is extremely 

 slow-growing; is not particularly hardy in my garden; 

 and makes a small irregular bush, but its colour is so 

 distinct that no collection can afford to omit it. 



In summer its foliage and branchlets become a wonder- 

 ful glaucous sea-green or blue, and in winter they take on 

 the bloom and colour of a crimson plum. It seems to 

 suffer more from cold winds than actual frost, and should 

 be planted in a sheltered spot. It has been killed by frost 

 at Orleans, but has withstood cold down to 4° F. in my 

 garden with shelter. 



It was first imported from Yokohama by Bohmer in 

 1894, and found its way to England soon after finding its 

 way into commerce, and was described first under the 

 name of Juniperus Sanderi (1899 — Gard. Chron., p. 287). 

 About the same time Louis Bohmer and Co., of Erfurt, 

 catalogued it as C. ohtusa, var. ericoides, but it continued 

 to be distributed as Juniperus and then as Retinispora 

 Sanderi. 



C. obtusa, var. nana prostrata. 



A form I have only recently received. roliage,branches, 

 and branchlets similar to var. nana, but branchlet tips very 

 pendulous. It is said to cover the ground with wide- 

 spreading mat-like branches. 



C. obtusa, var. tetragona. 



Syn. : Retinispora tetragona, Barron ex Gordon 

 ("Pinetum," 29, 1875). 

 R. thuyoeformis, R. Smyth ex Gordon.
