Pinetum Wobiimcnse. 



in our Arb. Brit. p. 2190., and in Ilort. Lig. p. 117. Whether it is distinct or 

 not, it is a very handsome species, well deserving of cultivation, and it appears 

 to be tolerably hardy. It was introduced in 1837, by Mr. Knight of the 

 Exotic Nursery, King's Road, Chelsea, and named by him "in compliment to 

 the Earl of Harrington, who is devotedly attached to this tribe of plants, and 

 who has formed extensive avenues, and various objects, with the yew, at 

 Elvaston Castle." The following specific character and descriptive particulars 

 are given by Mr. Forbes : — 



" Leaves distich-flat, from 1 in. to 1^ in. in length, dark green and shining on 

 the upper surface, of a white glaucous hue beneath, with the exception of the 

 midrib and revolute margins, which are of a bright green colour. The apex 

 mucronate, footstalks short, branches round and furrowed. 



" The T. Harringtoni« is readily distinguished from all the well authenticated 

 species by its longer revolute leaves, which are of a silvery glaucous colour on 

 the under side ; the edges are bright green, as well as the midrib, which is 

 very prominent on the upper surface. The branches are rounded, and 

 striated, forming a somewhat pendulous habit of growth." 



Tdxus nucifera, Pin. Wob. p. 218., Arb. Brit. p. 2100., Hort. Lig. p. 117. 

 There is a good plant of this very rare species in the ample collection of W. 

 Harrison, Esq., at Cheshunt, Herts. 



Tdxus Makoya, Pin. Wob. p. 218. Leaves linear, acute; edges slightly re- 

 volute; dark green, and shining above, pale beneath ; midrib prominent. This 

 appears to be a very distinct-growing plant from any of the species already 

 described, producing much narrower leaves, which vary in length from 1 in. to 

 li in., and are terminated by a sharp point. It was discovered in Japan by Dr. 

 Siebold. The species was sent to the Woburn collection by Mr. Low. 



Dacrydium cupressinum, Pin. Wob. pi. 67., Arb. Brit. p. 2100., Hort. Lig. 

 p. 117. 



The Duke of Bedford, in an addendum, states that, whilst the Pinetum 

 Woburnense was in the press, a severe storm occurred on the morning of Ja- 

 nuary 6. 1839, which destroyed several very fine trees in Woburn Park and 

 plantations ; amongst these were a cedar of Lebanon, 83 ft. high, and contain- 

 ing 220 ft. of timber ; a silver fir, 100 ft. high, and containing 120 ft. of timber ; 

 and a Scotch pine, 86 ft. high, and containing 72 ft. of timber. These trees 

 were planted in 1743. 



The chief circumstance in which the Pinetum Woburnense and the article 

 on .^bietinae and Taxaceas in the Arboretum Britannicum differ, is in the for- 

 mer making species in several cases where we make only varieties. The fol- 

 lowing comparative list will show the cases to which we refer, and may prove 

 useful to the young gardener : —
