Tilia 1655 



9. Tilia spedabilis, Dippel. See p. 1686. 



A hybrid similar to T. Moltkei, but with smaller leaves, which have long hairs 

 on the principal nerves, as well as on the midrib. Buds pubescent in their upper 

 half. Branchlets with traces of stellate pubescence. 



(b) Under surface of the leaves with axil-tufts. 



10. Tilia Michauxii, Nuttall. North America. See p. 1689. 



Leaves usually large, 1 5 to 7 in. in length and 4 to 6 in. wide ; ovate-cordate, 

 very oblique at the base, with long-pointed large triangular serrations. Buds 

 and branchlets glabrous. 



III. Leaves white or grey beneath, and covered with a dense stellate 



TOMENTUM. 



(a) Branchlets glabrous. 

 * Axil-tufts present. 

 ioa. Tilia Michauxii, Nuttall. In some forms of this species the leaves are 

 densely greyish tomentose beneath. See above, No. 10. 



* Axil-tufts absent. 



11. Tilia heterophylla, Ventenat. North America. Seep. 1688. 



Leaves ovate-cordate, very oblique at the base, 4 to 5 in. long, 3 to 4 in. 

 wide, covered beneath with a silvery white tomentum ; serrations coarse and 

 short-pointed. 



12. Tilia Oliveri, Szyszylowicz. China. See p. 1681. 



Leaves orbicular-ovate, 3 to 4 in. long, 2\ to 3 in. wide, silvery white beneath ; 

 serrations minute, crenate. 



(b) Branchlets pubescent. 

 * Axil-tufts present. 



13. Tilia Maximowicziana, Shirasawa. Japan. See p. 1683. 



Leaves orbicular-ovate, averaging 5 in. long and broad, covered beneath with 

 a greyish tomentum ; axil-tufts and tomentum on midrib and nerves brownish. 



** Axil-tufts absent. 



14. Tilia tomentosa, Moench. South-eastern Europe, Asia Minor. See p. 1675. 

 Leaves orbicular-ovate, 3 to 5 in. across, greyish or snowy white beneath, with 



stout or slender short petioles ; serrations fine, regular, ending in short points. 

 Buds, branchlets, and petioles grey tomentose. 



15. Tilia petiolaris, Hooker. See p. 1677. 



Possibly a sport of T tomentosa, from which it differs in the pendulous 

 habit of the tree, the long slender petioles, and the peculiar fruit. 



16. Tilia mandshurica, Ruprecht and Maximowicz. Manchuria, North China, 



Korea. See p. 1682. 

 Leaves orbicular-ovate, 4 to 5 in. across, white beneath ; margin often one- to 

 two-lobed, with coarse serrations, ending in long awn-like points. Branchlets, 

 buds, and stout petioles brown tomentose. 



1 In native specimens the leaves are smaller, averaging 4 to 5 in. long and 3 to 4 in. wide.
