NOTES 423 
QUILLAJA. 
Q. Saponaria, the quillai or soap bark tree, was given to Mr. 
Daniel Hanbury by M. Thuret, Antibes, in October, 1871. The 
two trees are now about 15:50 m. high, and have stems about 
1:74 m. in circumference. 
RaMona. 
R. grandiflora is a rather pretty perennial or subshrub, with 
large red flowers. FR. polystachya, which is far less attractive, 
shows interesting movements of the style, which is finally bent to 
one side of the flower. 
RAPHIOLEPIS. 
R. indica, one of our prettiest shrubs, rarely produces seeds, 
whilst &. japonica fruits abundantly. 
REEVESIA. 
R. thyrsoidea was grown from seeds received by way of Kew 
from Hong Kong Botanic Garden in January, 1883. Itis a shrub 
about 2°50 m. high. 
RESEDA. 
For a long time much doubt existed regarding the native 
country of the Mignonette (A. odorata), but it is now ascertained 
that it is the Cyrenaica, where the late Dr. Taubert collected the 
plant near Derna,* in 1887. Prof. Schweinfurth recalls the fact 
that it was introduced at the Jardin des Plantes, about two hun- 
dred years ago, by the French traveller Granger. 
RHIPSALIS. 
Most of the species of this genus can be grown here epiphyti- 
cally in the open, and do perfectly well. A. funalis (=f. grandi- 
flora Haw.) and R. pachyptera were first introduced by Mr. 
Daniel Hanbury in July, 1868. 
We owe most of our species to the Botanic Gardens of 
Dahlem, Kew, and Paris; to Dr. Weber, Mr. Weingart, &e. Two 
species were received from Mauritius through the kindness of 
Dr. Koenig, several from M. C. Wercklé, of San José de Costa 
Rica, and from Prof. C. F. Baker, of Cuba. 
RHODODENDRON. 
Except Ff. indicum we cannot grow any species of this 
genus, on account of the calcareous nature of soil and water. A. 
arborewm we had for some time, but it ultimately perished. 
Ruus. 
Several species of this genus are known to be extremely 
poisonous. f. venenata and f. vernicifera have proved so here.
