writers, and T. Menziesii by others. By Carriere and Hoclistetter the 

 Libocedrus decurrens of Torrey is described under the name of Thuya 

 gigantea. There is, therefore, a confusion in the nomenclature of the 

 two species, which it is very desirable should be got rid of. It 

 originated in this manner: "A few years previous to the intro- 

 duction of T. Lobhii to British gardens, Nuttall, an American 

 botanist, published his ' Plants of the Rocky Mountains.' At 

 page 52 of that work a Thuya is described under the name of 

 T. gigantea, which some refer to T. Lohhii, and others to the 

 Libocedrus decurrens of Torrey, discovered during the overland 

 expedition to California conducted by Colonel Fremont in 1843 or 

 1844. The Libocedrus was first received in Great Britain by the 

 Scotch Oregon Association, through their collector, John Jeffrey, 

 without a name, a few months earlier than the Thuya was received by 

 Veitch at the Exeter nursery from William Lobb. The Oregon Com- 

 mittee named Jefirey's tree T. Craigiana, in compliment to Sir 

 William Gibson Craig, one of their members, Torrey's designation 

 being at that time unknown to the Committee, and it was distributed 

 among the members of the Association under that name, but Carriere's 

 name, T. gigantea, became generally current in English gardens. 

 T. Lobbii was notd istributed till three or four years later ; and the 

 late Mr. James Yeitch, finding a T. gigantea already in cultivation, 

 and desirous of paying a well- merited tribute to the exertions of 

 Lobb, selected this beautiful Thuya to perpetuate his name " (Veitch, 

 A Manual of Conifers 



From Germany we learn that Thuya gigantea in some places does 

 not thrive well. In the Gartenjlora ((1892, v. 122) Dr. G. Dieck, of 

 Zoschen by Merseburg, says in reference to it : "I can report that in 

 this locality only a few well-sheltered single plants have survived the 

 last winter (i. e. 1890-91). In my park it was necessary to cut down 

 the two last strong specimens which under fear and pain had reached 

 a diameter of about 15 cm." 



To these remarks I may add that some plants of the Thuya 

 gigantea in Denmark also suffered from the long and hard winter 

 of 1890-91, but I do not think it was necessary anywhere to cut the 

 plants down, and to the best of my knowledge all have recovered. 

 On low ground young plants sometimes become red in spring-time, 

 and some of them die. But in better localities, on light warm ground 

 as well as in more loamy soil, we see fine old plants develop them- 

 selves into grander and grander beauty. Around Copenhagen fine eld 

 plants are to be seen. From a locality at Elsinore I am informed by 

 the nurseryman Zeiner-Lassen that at his place the species does not 

 succeed. In Jutland some trials were successful. 



Thuya gigantea has in several Danish gardens attained a height of 

 40 feet and more. A specimen planted in 1864, and recently 

 measured, was 36 feet in height, and 2 feet 6 inches in girth.
