1636 The Trees of Great Britain and Ireland 



specimens of the species, which were collected in Tasmania on the summit of Mount 

 Wellington by Gunn, and on the western mountains by Lawrence ; but have larger 

 leaves, and are usually more glaucous in all their parts.^ 



E. cocci/era is confined to Tasmania, where it is common on the summits of 

 the mountains at 3000 to 4000 ft. elevation. Rodway describes it as a small erect 

 tree, 8 to 12 ft. high; but it attains much larger dimensions in this country, and 

 doubtless owes its small size in Tasmania to the exposed situations in which it is 

 found. It is known as mountain peppermint, and has no economic value in its own 

 country. 



E. cocci/era was discovered in 1840 by Gunn, and was probably introduced in 

 the same year, as in 1851 there was a plant, said to be eleven years old, growing in 

 Veitch's nursery at Exeter, which was then 20 ft. high and producing flowers. In 

 the Chiswick Garden, according to Lindley, it lived for many years against a south 

 wall, without being injured by frost ; but plants growing in open borders dwindled 

 away and died. (A. H.) 



Remarkable Trees 



The finest Eucalyptus in Britain is the noble tree^ of this species, which 

 grows in the American garden at Powderham Castle, Devonshire (Plate 361). 

 When I last measured it in 1907, it was 75 to 80 ft. high and 13 ft. in girth at 5 feet; 

 but the gardener, Mr. Bolton, informs us that in January 191 1 it was exactly 16 ft. 

 in girth at 4 ft. from the ground ; the spread of the horizontal branches being about 

 90 ft. It is perfectly sound and healthy, and regularly bears ripe fruit, from which 

 seedlings have been raised. One of these, when planted out under a warm wall at 

 Colesborne was almost killed in the winter of 1908- 1909; and died in 19 12. 

 This tree probably dates from the original introduction of the species in 1840, 

 as it produced flowers and fruit in 1852, from which the plate in the Botanical 

 Magazine, t. 4637, was drawn. It grows in sandy loam on the Red Sandstone 

 formation on a fairly high river bank, about ten yards from the water, and 

 doubtless owes its vigour to this situation. It was not injured in 1878 or 1879, 

 when the temperature fell to 16° and 9° Fahr. respectively. Masters^ states that 

 this tree has changed its time of flowering, as it was reported to have produced 

 flowers in December and January, 1880; while in 1883, it was in full flower in the 

 month of June. (H. J. E.) 



and flower-buds like E. Risdoni and E. coccifera in all probability are hybrids. Rodway, Notes on E. Risdoni in Proc. 

 Roy. Soc. Tasm. 367-369, plates 10-12 (1910), should be consulted on the varieties of this species. 



B. Eucalyptus radiata, Sieber, var. 4, J. D. Hooker, Fl. Tasman. i. 137 (i860). 



This name was given by Hooker to specimens iioo and 11 10, collected by Gunn in 1840 at Hobart and Grass Tree 

 Hill. These two specimens arc not identical, and are different from E. Risdoni, var. elata, from Lake St. Clair, They are 

 close to E. Risdoni, and are probably hybrids of it with some other species. 



Note. — E. Risdoni, Hooker, the "drooping gum,'' a small tree abundant in the dry hills of the southern parts of 

 Tasmania, bears on the adult plant opposite sessile leaves ; and seems to be entirely distinct from E. Risdoni, var. elata. 

 E. Risdoni does not seem to have ever been tried in cultivation in England. 



1 Maiden, to whom I sent specimens of the Powderham and other trees, agrees with me that they are undoubtedly 

 E. coccifera, 



2 Figured in Card. Chron. xii. 113, fig. 18 {1879), and ii, 784, fig. 152 (1897), It was reported to be 58 ft. high and 

 7 ft. 4 in. in girth at 3^ ft. from the ground in 1879, Cf. also Card. Chron. xxxiv. 291 (1903) and xxxix. 411 (1906).
