hwa,” and (for their own use) the petals of a rose, “ Tsing moi- 
qui-hwa.” It has been frequently stated that the flowers of 
Chloranthus inconspicuus are used for scenting tea, but this has 
long been disproved by Fortune, a botanist who resided in China 
and studied the genus Chloranthus, one species of which, C. For- 
tunei, was specifically named after him. 
Some flowers, such as those of the Aglaia, after being sifted out 
from the tea, are dried and used in the manufacture of the frag- 
rant “ Jos-stick,” which is much used as an incense in the religious 
ceremonies of the country. 
The fruit of the Evodia fraxinifolia yields by distillation about 
4 per cent. of a thin fluid essential oil of a very pale yellow colour, 
and exceedingly agreeable and intense odour, similar to bergamot ; 
so intense is the perfume that it is able to overcome the smell of 
iodoform, even when used in the very small proportion of two 
drops to the ounce. The sp. gr. of the oil is very low, not 
exceeding 0°840 ; it is soluble in alcohol and ether *. A descrip- 
tion of Hvodia fraxinifolia was first published under the name of 
Rhus fraxinifolium in Don’s ¢ Prodromus Flore Nepalensis,’ 1825. 
The plant is described as a large tree, a native of Nepal. Sir 
William Hooker, however, subsequently poimted out that the 
floral characters did not agree with those of the genus Rhus. 
In the ‘Icones Plantarum’ 1848, plate 170, it is referred to 
Blume’s Philagonia, and a good figure accompanies the letterpress. 
The plant is placed under the natural order Terebinthacee, and 
a reference is given to Tetradium (?) fraxinifolium, of Wallich, in 
Herb. Hook. 1821. In the recent work, Hooker and Bentham’s 
‘Genera Plantarum,’ this species is included in the genus Evodia, 
under the natural order Rutacee, and it is identified with the 
Tetradium trichotomum described in Loureiro’s ‘ Flora Cochin- 
chinensis,’ p. 91, which is there mentioned as having trichotomous 
racemes of whitish flowers ; the tree is of medium size, and inhabits 
the hills of Cochinchina fF.
