1826 The Trees of Great Britain and Ireland 



Whether either of the " Eucalyptus " poplars will equal in vigour the black 

 Italian poplar, if planted in this country, remains to be proved ; but the trial is worth 

 making, as they are evidently most profitable to grow in France. 



Other reputed forms of P. regenerata or of P. serotina, which are classed 

 under the term Peupliers rdgdnirds^ are mentioned by M. Breton- Bonnard ; but none 

 of these have as great a reputation as those which are propagated at Pontvallain. 



Specimens sent by the late Dr. Blasius from trees growing in the garden of 

 Cramer von Klausbruch at Brunswick, which he considered to be the pistillate 

 form of P. serotina, are similar in foliage to P. regenerata. 



This hybrid has lately come into cultivation in England, the only large tree which 

 I have seen being one in the Queen's Cottage grounds, Kew, which displays no 

 vigour of growth. A tree at Kew, obtained under the name P. deltoidea erecta from 

 Dieck in 1889, and now about 35 ft. high, produced female flowers in 191 1, which 

 showed it to be identical with P. regenerata, of which it has the foliage and habit. 

 A female tree at Glasnevin, cultivated under the name P. rdgdndrd, and about 60 ft. 

 in height and 4 ft. 11 in. in girth in 191 2, resembles P. Eugenei in habit, and is 

 very thriving. It was obtained from Simon- Louis in 1892. 



Mention may be made here of a peculiar poplar ^ at Beauport, Sussex, 60 ft. by 

 3 ft. in 1909, which was blown down in August 191 2, the day before I last visited 

 this remarkable collection of trees of all kinds. It differed from P. regenerata in 

 having smaller leaves, 2 to 2\ in. long and broad, similar to those of P. monilifera, 

 var. occidentalis, in shape, size, and few coarse serrations ; but like the hybrids in the 

 sparse ciliation of the margin and the irregular number (o, i, or 2) of glands at the 

 base. It bore female catkins in April 191 2 ; and the flowers with only two stigmas 

 showed also its hybrid origin. A similar tree, judging from a specimen in the Kew 

 Herbarium, grew at Carlsruhe in 1845. (A. H.) 



POPULUS EUGENEI 



Populus Eugenei, Simon-Louis, ex Koch, Dendrologie, ii. pt. i. p. 493 (1872); Schneider, Laubhoh- 

 kunde, i. 9 (1904); Dode, in Mim. Soc. Hist. Nat. Autun, xviii. 46 (1905); Ascherson and 

 Graebner, Syn. Mittekurop. Fl. iv. 45 (1908). 



Peuplier Euglne, Carrifere, in Rev. Hort. 1865, p. 58. 



Populus pyramidalis meetensis, Mathieu, in Gartenflora, xxxvi. 674 (1887), translated in Gard. 

 Chron. ii. 818 (1887). 



A narrow pyramidal tree of hybrid origin, with a straight undivided stem and 

 numerous short branches, mostly ascending at an angle of 30° to 45° with the stem. 

 Young branchlets glabrous, slightly angled. Buds small, reddish-brown, viscid. 

 Leaves (Plate 409, Fig. 17) unfolding early in the season, with a reddish tint, smaller 

 than those of P. serotina, averaging 2^ in. in width, usually broadly cuneate, rarely 



1 This peculiar hybrid appears to be identical with P. incrassata, Dode, op. cit. 41 (1905), described as a pistillate tree, 

 having flowers with two stigmas ; leaves thick in texture, moderate in size, deeply cordate at the base, acuminate at the apex. 

 The leaves of the Beauport tree, often cordate, occasionally truncate at the base, ^ree with those of a specimen kindly given me 

 by Dr. Dode as the type of his P. incrassata.
