Koelreuteria I 93 I 



2. Koelreuteria paniculata, Laxmann. See p. 1932. 



Leaflets, nine to thirteen, \\ to 3 in. long, toothed or lobed in margin ; 

 occasionally some of the leaflets are so deeply cut that the lobes are distinct, 

 making the leaf incompletely bipinnate. Capsule, with ovate acuminate valves, 

 1^ in. long, and f in. wide ; seed \ in. in diameter. 



1 1 . Leaves bipinnate, with an even number of pinna, which bear an even or odd number 

 of leaflets. 



3. Koelreuteria Henryi, Dummer, in Gard. Chron. Hi. 148 (1912). 



Leaflets alternate, five to eleven, 3 in. long, glabrous except for axil-tufts 

 beneath, serrate. Branchlets glabrous. Capsule with broadly oval or orbicular 

 valves, about i in. across ; seed \ in. in diameter. 



This is a tree, attaining about 50 ft. in height, which was discovered by me 

 in 1894, near Bankinsing in the mountains of central Formosa. . It has not yet 

 been introduced, but might possibly be hardy in the milder parts of England 

 and Ireland. 



4. Koelreuteria bipinnata, Franchet, in Bull. Soc. Bot. France, xxxiii. 463 (1886), 



in Rev. Hort. lx. 393, fig. 93 (1888), and PL Delav. 143, pi. 29, 30 (1889). 



Leaflets opposite, sub - opposite, or alternate, nine to thirteen, 3 in. long, 

 pubescent on the midrib and veins, serrate. Branchlets pubescent. Capsule 

 with oval or elliptic valves, rounded at the apex, about 2\ in. long and \\ to 

 2 in. broad ; seed \ in. in diameter. 



This is a tree, attaining 90 ft. in height in mountain woods in central and 

 south-western China. It was discovered in 1887 by Delavay near Tapintze, 

 north-east of Tali in Yunnan, at 6000 ft. elevation. It was subsequently 

 found by me near Mengtse in the same province, and in the hills north of 

 Ichang in Hupeh. Faber collected it in the mountains near Ningpo in 

 Chekiang. 



In 1887 Delavay sent home seed, which germinated freely in the Jardin des 

 Plantes at Paris. One of the seedlings, which has been in the Temperate 

 House at Kew since 1889, is now about 40 ft. high, but has not as yet borne 

 flowers. This species has not apparently been tried in the open air in this 

 country, but is likely to prove hardy in mild districts like Cornwall. It is 

 rare ' on the Continent, but is reported to be growing at Les Barres 2 and at 

 the Villa Thuret, Antibes. 3 (A. H.) 



1 Simon-Louis, Cat. 1908, p. 44, mentions it as very tender to frost at Metz.
