1 662 The Trees of Great Britain and Ireland 



(var. multibracteata) in which two bracts are borne on one peduncle. The fruit is 

 remarkably variable, both in shape and in the prominence of the ribs. 



The southern more glabrous forms are rarely cultivated in England, the only 

 specimen which I have seen being a tree at Kew about 25 ft. high, which is named 

 var. obliqua. 1 The branchlets are nearly glabrous ; leaves very oblique and truncate at 

 the base, glabrous above, with scattered pubescence below. It bears flowers similar 

 to those of the type. 



A large number of sports have arisen both under cultivation and in the wild 

 state, the most noteworthy of which are : 



1. Var. pyramidalis, Simonkai, in Math. Term. Koezl. 334 (1888). Pyramidal 

 in habit ; leaves usually more or less cordate at the base. According to Schneider 

 this is occasionally wild in south-eastern Europe. 



2. Var. tortuosa, Bean, in Kew Hand-list Trees, 71 (1902). A peculiar sport, 

 with all the twigs and branches twisted and curved. This s originated in the Royal 

 Horticultural Society's garden at Chiswick in 1888 as a single specimen out of a bed 

 of 500 large red limes. Grafts were sent to Kew from Chiswick in 1 890, and three 

 trees about 18 ft. high survive, in the Lime collection. 



3. Var. aurea, Loudon (var. aurantia). Twigs golden yellow. 



4. Var. corallina, Solander, in Aiton, Hort. Kew. ii. 229 (1789). Twigs bright 

 red. Both these varieties are conspicuous in winter, and have been known for more 

 than a century. According to Koch they were probably introduced from England 

 to the Continent. The latter is the red-twigged lime of some English nurseries. 



5. Var. laciniata, Loudon (var. aspleniifolia, var. filicifolia). Leaves smaller 

 than in the type, deeply and irregularly cut and twisted. This never attains a large 

 size, 3 and is only suitable for planting as a curiosity in gardens. It commonly throws 

 out branches on which the foliage is normal. 



6. Var. vitifolia, Simonkai, op. cit. Leaves lobulate or weakly three-lobed. 



7. Forms with variegated leaves are known, as var. albo-marginata, Van Houtte. 



8. Var. cucullata, Schneider (T cucullata, Jacquin, 4 Frag. Bot. 19, t. II, f. 3 

 (1800)). A form with small leaves, of which the edges of the two sides are joined 

 together at the base, making the leaf pitcher-shaped. It is said to occur wild 

 in southern Bohemia, where, according to Willkomm, there are some old trees, 

 with all the leaves showing this peculiarity, at the monastery of Goldenkron, near 

 Krumau. 



Distribution 



This species is widely distributed throughout central and southern Europe, 

 extending as far eastward as the Ural Mountains. Its northern limit as a wild tree 

 is not known with certainty, and Willkomm considers it not to be indigenous in 



1 Probably identical with T. obliqua, Host, in Schmidt, Oestr. Baumz. iv. t. 224 (1822), and Host, Fl. Austr. ii. 62 

 (1 83 1). The Kew tree agrees with a dried specimen collected in Host's garden in 1832. 



2 Cf. Card. Chron. iv. 708 (1888). 3 A. B. Jackson saw a tree at Blenheim, 40 ft. by 3^ ft., in 1908. 



* Jacquin figures leaves from trees in a cemetery at Sedlitz, near Kuttenberg in Bohemia. Leneck, in Mitt. Nat. Ver. 

 Univ. WUn, 1893, pp. 19-29, figs. 1 - r 1 , gives an account of these abnormal leaves ; and records a large-leaved lime growing 

 at Leitmeritz in northern Bohemia, of which 20 to 30 per cent of the leaves were pitcher- or cowl-shaped. Cf. Just, Bot. 

 Jahresb. xxii. pt. 2, p. 219 (1894).
