TILIA 591 



smooth, except for tufts of hairs in the axils of the veins; marginal teeth small, 

 regular and slender; stalk smooth, I to 2 ins. long. Flowers produced in 

 the latter half of July, three to seven together in cymes 2 to 4 ins. long, 

 yellowish white. Floral bract linear-oblong, or narrowly lance-shaped, 2 to 



3 ins. long, 5- to in. wide, smooth, shortly stalked. Fruit distinctly ovoid, 

 tapered to a point, shaggy, with pale brown wool, j to J in. long. 



Of doubtful origin ; introduced about 1860. In some respects this is the 

 most beautiful of the limes on account of its bright green large leaves and 

 pleasing form. It is remarkably free from insect pests. In the summer of 

 1909, when not only limes but nearly every other tree and shrub was infested 

 with aphides and other pests, I examined specimens of this lime at intervals 

 during the summer, and never found a single parasite on the leaves. Yet it 

 is quite uncommon in this country. On the Continent, however, its qualities 

 are better appreciated, and it is being much planted in streets. Its brilliantly 

 glossy, rounded, nearly glabrous leaves and pendulous branches very well 

 distinguish it. It has been suggested that it is a hybrid between T. cordata 

 and the scarcely known T. caucasica found in the Caucasus. 



T. HENRYANA, Szyszylowicz. 



A tree 30 to 50 ft. high, the branchlets at first stellately downy, ultimately 

 smooth. Leaves obliquely and broadly ovate, heart-shaped or cut off straight 

 at the base, shortly taper-pointed, 2 to 5 ins. long, \\ to 3 ins. wide ; the 

 margin set with bristle-like teeth ^ in. long> the midrib and veins downy 

 above, the whole under-surface covered with dull brownish stellate down; 

 there are tufts of down in the vein-axils; stalks I to i ins. long. Flowers 

 whitish, numerous (twenty or more), on cymes 4 to 6 ins. long; floral bracts of 

 similar length, \ to f in. wide, stellately downy, especially behind. 



Native of Central China; discovered by Henry in 1888; introduced for 

 Messrs Veitch by Wilson in 1901, and said by them to be quite hardy at 

 Coombe Wood. It is distinct from all the species here mentioned in the 

 almost hair-like teeth of the leaves. 



T. HETEROPHYLLA, Ventcnat. 



It is doubtful if there be any living trees of this lime in the British Isles; 

 what are cultivated under the name being usually T. Michauxi, which is 

 believed to be a natural hybrid between T. americana and T. heterophylla, 

 and in some of its forms closely approaches the latter. But, according to 

 Sargent, T. heterophylla can always be distinguished by having no tufts of 

 hairs in the vein-axils beneath the leaf. The leaves 'are always covered 

 beneath with a close layer of silvery down. It is a tree 50 to 80 ft. high in 

 a wild state, with a trunk 9 to 12 ft. in girth, and is a native of the eastern 

 United States from New York to Alabama, reaching its largest size in the 

 forests of the mountains of N. Carolina and Tennessee. Its leaves are 



4 to 8 ins. long, with slender stalks up to 3^ ins. long. It is hardy in the 

 Arnold Arboretum, Mass., but appears to have always been a neglected tree. 



T. MANDSHURICA, Ruprecht. MANCHURIAN LlME. 



Apparently the only specimen of this lime in cultivation in Britain is a 

 small tree at Kew, now about 22 ft. high. Like so many Manchurian trees 

 and shrubs, it starts early into growth (before any other species), and is 

 almost invariably cut back by spring frosts. It might prove a handsome 

 tree in the south-western counties, but near London is of no value. It is
