THUYA 169 



There are two indisputed juvenile forms of T. orientalis 

 in general cultivation — namely, vars. juniperoides and 

 Rosedalis compacta. In both of these the leaves are 

 borne in opposite pairs, and are perfectly regular in 

 arrangement and direction, being wide apart and point- 

 ing outwards at rather a wide angle, with their tips in- 

 clined to recurve, and not to incurve. In colour the juvenile 

 forms of T. orientalis are bluish in summer and inclined 

 to turn a glaucous plum colour in winter. They have no 

 very distinct or pungent odour. 



Of T. occidentalis there is no indisputed purely juvenile 

 form, but there is an indisputed intermediate form — 

 var. Elwangeriana aurea — which bears juvenile foliage 

 in a young state and adult foliage on its upper branches. 

 The adult foUage has a strong Arbor vitoe smell; most of the 

 juvenile foliage has no smell that would distinguish it from 

 juvenile forms of T. orientalis, but upon a few branchlets 

 which bear both juvenile and adult foliage some of the 

 former has a very faint Arbor vitce odour when crushed, 

 and, speaking generally of juvenile forms, very little is 

 to be learned from their smell. 



But when the foliage of this indisputed form of T. 

 occidentalis — var. Elwangeriana aurea — is compared with 

 that of the two indisputed forms of T. orientalis, and 

 with that of the disputed T. occidentalis ericoides, it at 

 once becomes apparent that the juvenile fohage of 

 T. occidentalis, instead of being regular, widespread, 

 and tending to recurve like that of T. orientalis, is 

 irregular, mostly ascending, and tending to incurve in a 

 manner exactly similar to that of the disputed T. occi- 

 dentalis ericoides, and also to that of " T. Water eri " of 

 gardens (q.v.). 



When, added to the similarity in the arrangement of 

 foUage, it is also observed that its colour changes in 

 winter to that dirty brown-green shade that T. occidentalis 

 (type) becomes, and not the attractive plum colour that 

 forms of T. orientalis become, I think that there can be
