THUYA 167 



T. occidentalis, var. Ohlendorffii, Beiss. (" Hand.," 1887, 28). 

 Syn. : var. SpdtJdi, P. Smith. 



A most distinct form, the foliage being partly juvenile 

 and partly adult. The awl-shaped juvenile foliage 

 predominates, and occasionally some of the adult foHage 

 must be cut out, otherwise the plant becomes unshapely. 

 The two kinds of fohage grow out of the same branch. 

 Many of the branches are unusually long, straight, and 

 stiff, and bare of side branches except at their tops. The 

 juvenile fohage of these erect branches is stout, broad, 

 awl-shaped, and about J inch long, the leaves being 

 arranged in opposite pairs, and are recurved except at 

 their tips (which are incurved). 



The scale-hke foliage is minute — under yV inch — the 

 leaves being closely appressed to the branchlet, which in 

 this case is four-sided. 



Beissner (ii. 503) states that Ohlendorff cultivated this 

 form in Hamburg before it was named after Spath, and 

 for this reason named this variety var. Ohlendorffii ; but 

 it has been known in cultivation for many years as var. 

 Spdtliii. 



It forms a slow-growing, but somewhat irregular, 

 narrow, globular bush. 



T. occidentalis, var. lutea nana, Beiss. (ii. 507). 



Beissner describes this as a dwarf form of var. luteay 

 which is a narrow pyramidal shrub with typical fohage; 

 green-yellow in summer and deep yellow in winter. I 

 have not seen this dwarf form. 



T. occidentalis, var. Douglasi pyramidalis, Spath (Beiss. 

 ii. 509). 



A compact form raised in the Arnold Arboretum, with 

 crowded fern-hke branchlets, the branchlet tips being 

 sometimes cockscomb -like; not unhke Cupressus ohtusa 

 filicoides. The fohage is dark green with hghter tips.
