312 CATALPA 



with a heart-shaped base ; 4 to 10 ins. long, 3 to 8 ins. wide (in young trees 

 considerably larger) ; with short, slender points, sometimes slightly lobed at the 

 sides ; light green and ultimately nearly smooth above, more or less clothed 

 beneath, especially about the midrib and veins, with pale hairs ; odour when 

 crushed disagreeable ; stalk half to three-fourths as long as the blade. 

 Panicles broadly pyramidal, 8 to 10 ins. long and wide, many-flowered. 

 Corolla 1 1 ins. long and across, frilled at the margin, the tube bell-shaped ; 

 white with two ridges and two rows of yellow spots, and numerous purple spots 

 on the tube and lower lobe. Fruit slender, 6 to 15 ins. long, round, and about 

 as thick as a lead pencil. 



Native of the eastern United States ; introduced in 1726. It flowers at the 

 end of July and in August, and is at that season the most beautiful of flowering 

 trees. It is hardy, but is best adapted for the south of England. No garden 

 ought to be without one or more specimens, and young ones from seed ought 

 to be always coming on to succeed the older ones, for the species is not 

 particularly long-lived, and frequently declines when forty to fifty years of age. 

 It bears fruit in hot seasons, and a tree densely hung with the long, pendent 

 seed-pods has a curious aspect. 



Var. AUREA. Those who admire yellow-leaved trees will not find a more 

 striking one than this ; its leaves are wholly of a rich yellow, which does not 

 become dull or greenish as the season advances, but rather improves in colour. 



Var. KOEHNEI. Leaves yellowish green in the centre, with a wide margin 

 of yellow. 



Var. NANA. A dwarf form 3 to 6 ft. high, bushy, and with smaller leaves. 

 I have never known this to flower. Often wrongly called C. Bungei. 



Var. PULVERULENTA (G. Paul & Son). Leaves densely spotted with 

 white. 



Var. VARIEGATA (foliis argenteis). A worthless variety. Leaves blotched 

 with yellowish white. 



C. BUNGEI, C. A. Meyer. 



A tree 20 to 30 ft. high, of bushy habit. Leaves 2 to yj ins. long, \\ to 

 4^ ins. wide ; ovate or somewhat triangular, with a wedge-shaped or straightly 

 cut base ; sometimes entire, but often coarsely scalloped, so as to form one to 

 six large teeth on each side, mostly on the lower half; quite smooth at 

 maturity ; stalk half to two-thirds as long as the blade. Flowers not yet seen 

 in this country, but described as " white and purple" ; they are produced three 

 to twelve together in a flattish corymb. Corolla i\ ins. long and wide. 



Native of China, and evidently frequent in the neighbourhood of Pekin. 

 Although the true species was only introduced in 1905, through Prof. Sargent, 

 plants under the name have long been in cultivation ; these, however, are 

 nearly always C. bignonioides var. nana, but sometimes C. ovata. The true 

 C. Bungei is still very rare. Of its ornamental qualities little can yet be said, 

 but as represented by dried specimens at Kew, the inflorescence is small. Its 

 quite smooth leaves distinguish it from other cultivated species except the new 

 C. Duclouxii (q.v.). 



C. DUCLOUXII, Dode. 



(C. sutchuenensis, Dode.') 



This species has only very recently been introduced, and little can 

 yet be said of it. Its leaves are broadly ovate, 2 to 6 ins. long, i| to 4^ 

 ins. wide ; long and taper-pointed, the base broadly wedge-shaped, truncate, 

 or slightly heart-shaped ; quite smooth on both surfaces ; stalk i^ to 4 ins. 

 long. Flowers in perfectly smooth corymbs, with the lower divisions branched, 

 six to fifteen flowers in each corymb. Corolla about i^ ins. long and wide, 

 said to be pale pink with deeper spots. Seed-pods up to 2 ft. in length.
