Botanical Magazine for January.—The plants figured are eee 
(Knesebeckhia) dichroa, Sprague (t. 8412); Elliottia racemosa, 
(t. 8413); Berberis Wilsonae Hemsl. (t. 8414); poo (Herschelia) 
lugens, Bolus (t. 8415); Calcevlaria cana, Cav. (t. 8416). 
The Begonia is an aoe plant with peculiar siteig orange- 
scarlet flowers. ‘Though placed in the section Knesebechia it 
ge ai a somewhat isolated position and shows striking resemblance 
o B. maculata, Raddi, of the section Gaerdtia in which the two 
sees of the placenta bear ovules on their site surfaces only. 
B, dichroa may therefore be a hybrid between two species belonging 
to different sections, but there is no direct evidence in support of 
this view. The subject of the ee was obtained from Messrs. 
Haage & Schmidt, Erfurt, in 1907 
Elliottia racemosa is a shrub or sina! tree now confined to a very 
small area in northern Georgia and South Carolina, where it is a 
rare plant. The Kew plants were received from the late Mr. P. 
Berckmans, in 1902, a previous attempt to introduce it in 1894, 
having failed. One of the plants flowered well in July last, and its 
racemes of sweet-scented waxy white flowers were quite beauti 
The buds at first pendulous become erect shortly before expanding 
and the flowers when open are in a more or less horizontal position. 
Unfortunately all attempts to produce seed have failed. 
Among the many new forms of Berberts recently introduced from 
China B. Wilsonae is one of the most distinct and eS 
It was found by Mr. E. H. Wilson near Tatien-lu in 1903, 
was presented to Kew by Messrs. J. Veitch & Sons in ‘1907, 
It is a dwarf spreading plant suitable for rock garden culture, 
and at Kew the young plants tend to retain their foliage during 
the winter. 
Disa lugens is one of the “blue” Disas. Formerly it was con- 
fused with the nearly allied D. bar. bata, Sw., but 
distinguished by the metallic greenish-purple hue of its rcs In 
South Africa it is found on the Cape Flats in moist sandy s 
among Restiaceae at about 100 feet above sea level. The specimen 
which forms the subject of the plate was received from Mr. H. J. 
Elwes of Colesborne.
