TILIA EUCHLORA

 (1869); Schneider, Laubholzkunde, ii. 374 (1909); V. Engler, Monog. Gatt. Tilia, 149 (1909). 



Tilia multiflora, Simonkai, in Math. Term. Kbzl. xxii. 328 (1888) (not Ledebour). 



Tilia rubra, var. euchlora, Dippel, Laubholzkunde, iii. 63 (1893). 



Tilia dasystyla. Jack, in Garden and Forest, i. 332 (1888); Nicholson, in Kew Hand-list Trees, 45 

 (1894) (not Steven).! 



A tree, attaining 50 ft. in height and 6 ft. in girth, but possibly larger in its 

 native country. Bark grey and scaly. Young branchlets green, glabrous, the short 

 shoots, however, being slightly pubescent. Leaves (Plate 407, Fig. 10) intermediate 

 in size between those of T. cordata and T. vulgaris, averaging 2\ in. in width 

 and length, orbicular-ovate, coriaceous, cuspidate at the apex, oblique and cordate at 

 the base ; upper surface dark shining green, glabrous ; lower surface paler, almost 

 glaucous, glabrous, except for brownish axil -tufts at the base and at the junctions 

 of the midrib, primary and secondary nerves ; margin regularly serrate, the teeth 

 ending in long slender points ; petiole glabrous, slender, more than half the length 

 of the blade. Buds, with three external green glabrous ciliate scales. 



Cymes glabrous, pendulous, exceeding the leaves in length, three- to seven- 

 flowered ; bract glabrous, tapering at both ends, shortly stalked ; flowers similar to 

 those of T. platyphyllos, but the ovary is tomentose with long hairs, which are 

 continued on the base of the style, the upper f of which is glabrous. Fruit ovoid, 

 indistinctly five-ribbed, covered with dense short brownish grey tomentum, the base 

 of the style persistent at the apex ; shell thick and woody. 



This species is remarkably distinct in appearance, owing to the dark green 

 and remarkably glossy upper surface of the leaves. It comes into flower about the 

 end of July at Kew, later in the season than most of the limes, and the flowers have 

 a peculiar colour, owing to the distinctly yellow tinge of the petals and filaments. 



It has been much confused with T. dasystyla,^ Steven, a native of the Crimea, 

 which has leaves quite different in colour and shape, and, as its name indicates, a 

 densely tomentose long style. 



Tilia euchlora is represented in the Kew herbarium by a wild specimen from 

 Karabagh in Russian Armenia ; but it is supposed by Schneider and V. Engler to 

 be a hybrid ; and, if this is the case, its parents are possibly T. caucasica,^ 

 Ruprecht, the common large-leaved lime in the Caucasus, and T. cordata. It is 

 always propagated in nurseries by budding on the common lime ; and seedlings of it 

 appear to be unknown. 



1 Loudon, Ark et Frut. BHt. i. 366 (1838), refers to Steven's species from the Crimea, and not to the tree called by us 

 T. euchlora, Koch. 



2 T. dasystyla is represented in the Kew herbarium by Steven's type specimen and two other specimens, all from the 

 Crimea. 



3 The Caucasian lime can scarcely be identified with T. rubra, De Candolle, in Cat. Plant. Hort. Monsp. 150 (18 13), 

 which is described as having leaves pubescent beneath as in T. flatyphytlos, and evidently refers to the southern form of the 

 latter species in Europe.
