Syringa pinnatifolia, Hemsley [Oleaceae]. 
Although for many years there has been in cultivation a variet 
_of the Persian lilac with pinnatifid leaves, a species with genuinely 
pinnate leaves is a distinct novelty. S. pinnatifolia was discovered 
in Western China by Wilson in 1904, and was introduced by him 
for Messrs. Veitch. According to its discoverer it is a bush 6 to 
8 feet high, with slender branches and very elegant habit. The 
which are sessile, ovate-lanceolate, # to 14 inches long, } to 3 inch 
wide. The flowers are white with a slight tinge of lilac, produced 
in axillary panicles 14 to 3 inches long. The corolla is ot the 
ordinary narrowly tubular shape, 4 inch long, the spreading lobes 
+ inch long. The terminal portion of the leaf frequently shows a 
tendency to become pinnatifid instead of wholly pinnate. The 
species, which has recently been added to the Kew collection by the 
kindness of Messrs. Veitch, will no doubt be hardy, and_ will 
probably prove as ornamental in gardens as the white Persian lilac. 
Tripterygium Wilfordi, Hook. f. [Celastraceae]. 
In June, 1858, Charles Wilford, a young man then collecting for 
Kew in Formosa, first discovered this shrub on the banks o 
the river Sanar, on the north-west side of that Island. It 
was again collected in 1864 in Formosa by Wilford’s successor, 
the clever but ill-fated Richard Oldham, and since then it has 
been found in Corea, Japan and (by Mr. Henry) in Yunnan, But 
no attempt appears to have been made to introduce it alive until 
1905, when Mr. J. G. Jack, of the Arnold Arboretum, visiting 
Corea, collected it and introduced it to the United States. Since 
then it has been sent to Kew by Professor Sargent. 
It is a vigorous climbing shrub with angular, warty stems and 
deciduous alternate leaves, which are broadly ovate, long-pointed, 
cuneate or obliquely truncate at the base, crenately toothed, the 
largest 6 inches long and 4 inches wide; the smallest only one- 
quarter those dimensions. Flowers white, produced in panicles of 
varying size at the end of the shoot and in the axils of the terminal 
leaves, the whole making an inflorescence 6 to 12 inches long. 
Fruit three-angled and with three erect longitudinal wings ; the 
wings % inch long and } inch wide. The fruit has little ostensible 
resemblance to the other hardy Celastraceae, like Euonymus avi 
Celastrus, and suggests more strongly a Wych Elm fruit with an 
extra wing. but the species, which is monotypic, belongs to the 
Elaeodendron group, which has no other hardy representative in 
this country.
