161. HIS'lOUY AND GEOGIJAPIIY OV TREES. TAUT I. 



M. Dunant possesses, on his grounds at Sccheron, a Qnercus 7 lex, wliicli is 

 very fine for the country. 



At the entrance of tlie botanic garden there is an oUl Aildntus ghuididosa, 

 much oKler tlian the garden. It measured, in June, 1833, at the level of the 

 soil, 7 ft. 3 in. in circumference, and was between \5 ft. and 50 ft high. The 

 unpleasant smell of its flowers is perceived at half a furlong's distance, and 

 its numerous and troublesome suckers rise all round, as far as 40 ft. or oOft. 

 from the tree. 



The trees contained in the botanic garden itself are not old, as the garden 

 has not been established more than 17 years. Among the rarest and best- 

 •n-own trees which have been planted from 1.5 to 17 years, we may mention 

 the following: — A Photinia serrulata, spreading into liranches from its base, 

 and about 121 ft. high; a ]Magnoli« acuminata, about the same height, with a 

 trunk 7 in. in "circumference; a kcilreuteria, loft, high, with a trunk 13 in. in 

 circumference; and a tulip tree, 40 ft. high, 3 ft. oi in. in circumference; yrccr 

 striiitum, 24 ft. high, and 1 ft. Ih in. in circumference ; yJtJ'sculus fiava and 

 rubicunda, 30ft. high, and lift, in circumference; Pavia hybrida, 20ft. 

 high, and 14tV in. in circumference ; C'erasns serotina, 35 ft. high, and 2 ft. 4 in. in 

 circumference ; il/espilus Sniith« Dec, 20 ft. high, and I'ft. 8 in. in circumference ; 

 Cratic^gus nigra, about the same height, and 1 ft. 2^ in. in circumference ; 

 i/ippophae rhamnoides, and Z-Tlaeagnus angustifolia, 12 ft. high, and 1 ft. in 

 circumference; Planera crenata, 35 ft. high, and 1 ft. 9 in. in circumference ; 

 Populus angulata, which sometimes retains its leaves till Christmas, GO ft. high, 

 and 4 ft. in girt ; J'lnus cordiita, 35 ft. high, U ft. in girt ; (juercus alba, 1 8 ft. 

 high, and 2ft. 1 in. in girt; ./uniperus thurifera, 15 ft. high, and 1 ft. in girt; 

 Pinus Larlcio, 25 ft. high, and 2 ft. 4 in. in girt ; Pinus Miighits, 20 ft. high, 

 and 2 ft. 5 in. in girt; and Larix curopas'a, the branches of which hang in a 

 very singular manner, is 30 ft. high, and 2 ft. 5 in. in circumference near to 

 the base of the trunk. All these measurements were taken at such a height 

 from the ground as seemed most likely to give the true dimensions of the 

 trunk, and to avoid the thickness often produced by the graft, or at the base ; 

 and these measures were all taken by M. Alplionse De CandoUe, in October, 

 1835. It is to be wished that a register of similar measurements were opened 

 in every botanic garden, in order to verify the date of the introduction, and 

 the rate of growth, of every species, according to the diverse physical cir- 

 cumstances of each locality. (./. Dc C. Nov., 1835.) 



Sect. VII. Of the Indigenous and Foreign Trees and Shriths of 

 Italy, Greece, Spain, Portugal, and the Mediterranean Islands. 



Italy, having been, diu-ing the Roman empire and the dark ages, the 

 centre of civilisation in Europe, would, doubtless, draw from all other coun- 

 tries whatever of their productions was suitable to its climate. IIenc(! the 

 ligneous flora of Italy includes almost all the trees and shrubs indigenous 

 to Greece, Spain, and the Mediterranean islands, which are in any way remark- 

 able for their use or iieauty. In the following enumeration, taken from 

 Tenore's Flora Xcnpolilnnn, Bcrtoloni's Flora Italicn, Savi's Botanicon F/rii.s- 

 cum, Smith's Prodronius of Sil)thor[)'s Flora Grccca, Brotero's Flora Lusi- 

 tamca, Gnssone's Flora- Sicuhc Prodromitit, and Hopg's Obscritalioiia on the 

 Classical riaulx of Sirih/, we have includeil all the ligneous plants which are 

 indigenous, or apparently so, in these countries, and which are not included 

 in the indigenous flora of 13ritain. Those which are believed to be pecidiar 

 to any one or two of the countries, have the name of such countries following 

 the name of the plant.
