40 DWABF AND SLOW-GBOWING CONIFERS 



C. obtusa, var. compacta, Beiss. (ii. 562). 



Similar to the type except in habit, making a dwarf 

 compact conical bush, with short branches, and very 

 crowded branchlets. 



C. obtusa, var. nana densa, Hort. 



Syn. : var. Nana gracilis, Beiss. (ii. 562). 



A much denser form than the above. Branches 

 and branchlets very crowded and overlapping; fan- 

 shaped and twisted, and in more or less irregular, cup- 

 like layers; foliage flat (occasionally four-sided) and 

 scale-like, very dark lustrous shining green above and 

 glaucous beneath. On old specimens occasionally still 

 more crowded cockscomb-like growths appear on the 

 branch tips somewhat similar in appearance to the foliage 

 of var. ccespitosa {q.v.). 



This form makes an erect crowded little shrub, often 

 rather wider at the head than at the base ; it is very slow- 

 growing; the branchlet sprays being only about 2 J inches 

 long by 2 inches wide. At Curragh Grange a plant 

 having the foliage of this form has made a low, dense, flat- 

 topped bush of many upright branches about 18 inches 

 high by 2 feet across. 



C. obtusa, var. nana, Carr. (" Conif.," ii. 131). 



A form very near to var. nana densa, but branchlets not 

 twisted and set rather farther apart, not so crowded and 

 barely overlapping; differing also in shape, making a 

 spreading pyramidal bush ; foliage similar to that of nana 

 densa, but not so dark in colour. At the Arnold Arbore- 

 tum a very old plant of this form is now a pyramidal bush 

 8 feet high. 



C. obtusa, var. nana aurea. 



From the general appearance of young plants, this 

 would seem to be but a coloured variation of the above —
