TILIA

3812. Tilia vulgaris. 



ties are the following: Var. pyrarnidalis, Kirchn. Of 

 narrow pyramidal habit. M.D.G. 1898:161. Var. 

 corallina, Dipp. (var. rubra, Hort.). Young branches 

 red. Var. aurea, Kirchn. Young branches golden yel- 

 low. Var. laciniata, Henry (var. asplenifolia, Kirchn. 

 var. iUicifolia, Hort. T. europsea var. laciniata, Loud.). 



Lvs. deeply and irreg- 

 ularly cut, G.W. 15, 

 p. 662. Var. vitifdlia, 

 Simonkai. Lvs. slightly 

 3-lobed or indistinctly 

 lobed. This species is 

 the strongest grower 

 and in this country 

 often sold as T. 

 europaea. It is more 

 impatient of drought 

 than most other species 

 and therefore not to 

 be recommended as a 

 street tree. 



2. vulgaris, Hayne 

 (T. intermedia, DC. T. 

 europaea, Linn., in 

 part). COMMON LIN- 

 DEN. Fig. 3812. Tree, 

 to 120 ft.: young 

 branchlets glabrous: 

 Ivs. broadly ovate, 

 abruptly acuminate, 

 obliquely cordate or 

 truncate at the base, serrate with short-pointed teeth, 

 dark green above, light green beneath, glabrous except 

 axillary tufts of hairs, 3-4 in. long; petiole about half as 

 long as the blade: fls. 5-10, similar to those of the pre- 

 ceding species : fr. ovoid or globose, apiculate, tomentose, 

 thick-shelled. June, July; a week or 10 days later than 

 the preceding species. G.F. 2:256 (adapted in Fig. 3812). 

 R.F.G. 6:313. M.D.G. 1904:188, 189. Supposed to be 

 a spontaneous hybrid of the preceding species and T. 

 cordata. This is one of the best species for general 

 planting and fine old trees of it are occasionally seen in 

 this country. 



3. euchldra, Koch (T. dasystyla, Kirchn., not Stev. 

 T. rubra var. euchldra, Dipp.). CRIMEAN LINDEN. 

 Tree, to 50 ft.: young branchlets glabrous, green: Ivs. 

 orbicular-ovate, abruptly acuminate, obliquely cor- 

 date at the base, regularly serrate, the teeth with slen- 

 der points, dark glossy green above, paler beneath and 

 glabrous except axillary tufts of brown hairs, 2-3 in. 

 long; petiole slender, more than half as long as the 

 blade: fls. 3-7, in pendulous cymes; style pubescent near 

 the base: fr. ovoid, slightly 5-ribbed, tomentose, thick- 

 shelled. July. M.D.G. 1901:381, 540. Supposed to 

 be a hybrid of T. caucasifa, Rupr., and T. cordata and 

 seems to occur spontaneously in the Caucasus and 

 Transcaucasia. It is one 

 of the most beautiful lin- 

 dens on account of its 

 dark green glossy foliage. 

 It is usually prop, by bud- 

 ding. 



4. cordata, Mill. (T. 

 ulmifblia, Scop. T. parvi- 

 folia, Ehrh. T. micro- 

 ph ylla, Vent . T. silvestris, 

 Desf. T. europsa, Linn., 

 in part). SMALI/-LEAVED 

 LINDEN. Fig. 3813. Tree, 

 to 100 ft.: young branch- 

 lets at first slightly pubes- 

 cent, soon glabrous: Ivs. 

 suborbicular, often 

 broader than long, cuspi- 

 date, cordate at the base, 



regularly serrate with short-pointed teeth, dark green 

 and somewhat lustrous above, glaucous and glabrous 

 beneath with brown axillary tufts, 1J^-2H in. long: 

 petioles about half as long as blade: fls. 5-7 in nearly 

 upright cymes; style glabrous: fr. globose, slightly 

 ribbed, apiculate, tomentose, with thin fragile shell. 

 July. Eu. G.F. 2:257 (adapted in Fig. 3813). H.W. 

 3:41, pp. 21, 22. R.F.G. 6:311, 312. M.D.G. 1904: 

 188. Var. pyramidalis, Wittm. Of narrow pyramidal 

 habit, 



5. japonica, Simonkai (T. cordata var. japonica, 

 Miq.). Tree, to 60 ft,: young branchlets slightly pubes- 

 cent at first: Ivs. suborbicular, almost like those of the 

 preceding species, 2-3 in. long; petioles usually longer 

 than half the blade: fls. 740, in pendulous cymes; 

 staminodes present: fr. ovoid, not ribbed, tomentose, 

 thin-shelled. July. Japan. S.I.F. 1:72. 



6. mongdlica, Maxim. Small tree, to 30 ft.: young 

 branchlets glabrous, reddish: Ivs. suborbicular, or 

 ovate, acuminate, subcordate or truncate at the base, 

 coarsely serrate and usually 3-lobed, dark green and 

 shining above, glaucescent beneath, glabrous except 

 axillary tufts, l%-2% in. long: fls. 6-12 in a cyme; the 

 bract stalked; staminodes present; style glabrous: fr. 

 ovoid, mucronulate, tomentose, thick-walled. July. 

 Mongolia, N. China. R.H. 1902, p. 476. S.T.S. 1:61. 





3814. Basswood, or 

 American linden. Tilia 

 americana. ( x Ji) 



Very distinct with its small coarsely serrate, birch- 

 like Ivs. reddish when unfolding; it flowers when only a 

 few feet high. 



7. americana, Linn. (T. gldbra, Vent.). Fig. 3814. 

 Tree, to 120 ft.: young branchlets glabrous, green: Ivs. 

 broadly ovate, abruptly acuminate, cordate or trun- 

 cate at the base, coarsely serrate, the teeth long-pointed, 

 dark green above, light green beneath with tufts of 

 hairs in the axils of the lateral veins, but wanting at 

 the base, 4-6 in. long, turning yellow in autumn: cymes 

 pendulous, many-fld.: bract stalked, tapering toward 

 the base: staminodes present: fr. ovoid or globose, 

 without ribs, tomentose, thick-shelled. July. Canada, 

 south to Va. and Ala., west to X. Dak., Kans., and 

 E. Texas. S.S. 1:24. Mn. 6:153. Var. macrophylla, 

 Hort. (var. mississippiensis, Hort.). A large-lvd. form. 

 This species is frequently planted as an avenue tree. 

 Its wood is much used in the manufacture of wooden-
