rounded teeth at each side. Flowers crowded in terminal and 
axillary corymbs, each 1 to 13 in. wide. Corolla } in. long, 
bright violet-blue, with four short lobes and one long, fringed 
one. The calyx has a campanulate base and five lanceolate lobes 
which are tipped with violet. 
The species is allied to C. Mastacanthus but may be distin- 
guished by the more deeply divided lip of its corolla and the 
more coarsely toothed leaves. Kew is indebted to Major F. (. 
Stern of Highdown, Goring-on-Sea, for some plants which 
flowered very prettily last September. 
Evodia velutina, Rehder and Wilson. [Rutaceae.| 
The Evodias are rather handsome small trees of the Rue 
family and are allied to Phellodendron, differing in having exposed 
axillary buds whereas in Phellodendron they are concealed by 
the base of the petiole. H. velutina is a tree 40 to 50 ft. high, 
its young shoots clothed with velvety down. ‘The pinnate leaves 
are up to 10 in. long and composed of seven to eleven leaflets, 
which: are oblong-lanceolate, acuminate, obliquely rounded at 
the base, dull green and downy above, paler and clothed with 
a thick velvety pubescence beneath. Flowers yellowish white, 
small and very numerous, produced in August in a cluster of 
compound umbels at and near the end of the current season’s 
growths, the entire inflorescence being 6 or 7 in. long and wide; 
flowerstalks velvety. The individual flower is 4 in. wide, with 
narrowly oblong petals; calyx, ovary and the short, thick pedicel 
downy. Fruit } in. wide, purplish brown, downy, globose with 
a small beak. Seeds black and shining. 
This species is very distinct from the other species in cultiva- 
tion because of the velvety down on its younger parts. It was 
discovered and introduced by Wilson in 1908 (No. 994). He 
found it in one locality only in Western Szechuen. It first 
flowered in this country in the garden of Mr. C. J. Lucas at 
Warnham Court, Sussex, in August, 1918. It is evidently 
perfectly hardy at Kew. . 
Holboellia coriacea, Diels. {Lardizabalaceae. | 
Until the introduction of this species, which was effected 
by Mr. E. H. Wilson in 1907, the genus was only represented in 
gardens by H. latifolia, an old garden plant from the Himalaya 
which has never been much of a success in the open air except 
1921. , ‘ 
It is a vigorous evergreen climber and although Wilson gives 
its height as three to five metres, it appears capable of growing 
very much higher. The leaves are trifoliolate, the leaflets oval 
or oblong-obovate, 24 to 6 in. long, 1 to 3 in. wide (the middle 
one somewhat larger and longer-stalked than the two lateral 
ones), acuminate, rounded at the base, dark lustrous green,
