ing their hardiness in the op^en air, on the Hudson and at 

 Flushing, in New York, at Boston, etc., so that we shall 

 soon be made acquainted with their characters in this re- 

 spect. 



Var, anroa, Fortune, and rar. ar^entea, Fortune, 

 are two prettily variegated forms introduced from the 

 Japanese collections in the neighborhood of Yeddo, the 

 former marked with yello\v, and the latter with white. 



Var, pygfflaea, Gordon. Is known in some of the Eng- 

 lish collections as Thuja pygm&a, Yeitch. It is very 

 dense and small in all-its parts, dark green and glossy, and 

 altogether exceedingly desirable, according to foreign au- 

 thors. It grows from 1 to 2 feet in height, spreading hor- 

 izontally in every direction. Introduced into notice by 

 Fortune, in 1861. 



2. R, squarrosa, Siebold. This species has been classed 

 by Lawson with Cupressus, and by Endlicher with Cha- 

 mcecyparis. It is a small-sized tree, with graceful, droop- 

 ing branches, and glaucous-green foliage. This pretty lit- 

 tle species is from the Island of Kiusiu, and the moun- 

 tains of Sukejama. It scarcely ever exceeds 5 or 6 feet 

 in height, but is unfortunately too tender for our climate, 

 as it will not succeed- in England. 



Var. Yariegata, Siebold. " This variety," says Gordon, 

 " differs in having some of its branchlets and leaves of a 

 white color, intermixed with the ordinary green ones in a 

 variegated manner." 



3, R. pisifera, Siebold This is a small, slender tree 

 from the Island of Nippon. The branchlets and branches 

 are exceedingly nvfmerous, and the foliage very dense. The 

 cones are very small, and consist of numerous, small, im- 

 bricated scales. We regret to add that its hardiness with 

 us is somewhat doubtful.
