156 DWABF AND SLOW-GROWING CONIFEBS 



included only one or two juvenile forms whose origin 

 was not then known ; but of late years the name has been 

 so loosely used that in some niu-series one may find under 

 it, not only most of the smaller forms of cypresses, such as 

 C. ohtusa, C. pisifera, C. thyoides, but also of thuyas — 

 Thuya occidentalis and T. orientaUs. The parentage of 

 these juvenile forms has now been traced, and they will be 

 found under their proper names, and the name Retini- 

 spora is no longer recognised. 



SCIADOPITYS. 



Sciadopitys verticillata, Sieb. and Zucc. 



The umbrella pine is one of the most distinct conifers. 

 Though in Japan it reaches 100 feet in height, in Great 

 Britain it is rarely met with except as a shrub. Its whorls 

 of so-caUed leaves are like the framework of an umbreUa, 

 and it is so slow-growing that it can be utiUsed in small 

 gardens. 



There are pendulous and variegated forms in Eiu'opean 

 cultivation which I have not seen, and Beissner (ii. 449) 

 mentions dwarf forms without description, as existing in 

 Japanese gardens. 



SEQUOIA. 



Sequoia sempervirens, Endlich. 



Syn. : Taxodium sempervirens, Lamb. 

 One does not expect a species like the giant redwood of 

 California (which in its native habitat grows over 300 feet) 

 to produce a dwarf form, but I have met with one in 

 cultivation which, so far, promises to retaia its dwarf 

 habit : 



S. sempervirens, var. nana pendula. 



Syn.: var. pendula, Rovelli (in "Mitt. d. d. Ges.," 

 1899, 112). 

 Branches and branchlets pendulous ; practically pros- 

 trate.
