LIST OF PERFUMES, ETC., AND PLANTS WHICH AFFORD THEM. 167 
Sweet Flag (Acorus Calamus).—Long used as a perfume plant. 
It was the common perfume of the Romans, but they prized 
more highly the Roses of Psestum, Spikenard, Telinium, Mede- 
bafchrum, Onegalum, Balm of Gilead, and Cinnamon. 
Sweet-scented Golden Rod (Solidago odora). 
Syringa persica, &c. (Lilac).—One of the sweetest of hardy 
garden shrubs. Forced Lilac is deliciously sweet. 
Tansy (Tanecetum vulgare).—Fern-like foliage aromatically 
scented, and it is now and then used in order to try and keep 
flies out of rooms. Used also in cookery, Tansy puddings, &c. 
Thyme (Thymus vulgaris).—A well-known garden herb and the 
source of “Thymol,” &c. T. citriodorusis “Lemon Thyme.’ 
There are many species grown as rock plants, all more or less 
scented. 
Toddalia (Toddalia aculeata). 
Tonquin Bean = Seeds of Dipteryx odorata, Willd., from Guiana 0 
Tuberose (Polianthes tuberosa). 
Tussilago fragrans (Sweet Tussilage ; Winter Heliotrope).—An 
Italian plant naturalised abundantly near Dublin and else¬ 
where, and flowering freely in January and February, when 
roads and lanes are redolent with its Heliotrope-like perfume. 
It is a dreadful weed in many Irish gardens. 
Valerian (Valeriana Wallichii).—Now and then used as an 
aromatic, and in medicine more rarely as a stimulant and 
antispasmodic. The dried root of Valeriana officinalis is very 
attractive to cats, and is said to be employed by rat-catchers 
to decoy their victims to their traps. V. celtica has fragrant 
rhizomes used in toilet mysteries like Sambul. 
Vanilla (Vanilla planifolia, V. aromatica, and other species).— 
The fruits or beans are long and dark brown, or chocolate- 
coloured, and possess a very strong aroma, flavour, and per¬ 
fume. The essential flavouring principle of Vanilla can now 
be made artificially from Pine-tree sawdust. Both the natural 
and the chemical products are used for flavouring chocolate 
and other sweetmeats. Vanilla is sometimes adulterated with 
Tonquin Bean extract. 
Vegetable Wax or Candleberry (Myrica cerifera).—The fruits 
are coated with a waxy resin from which aromatic candles 
are, or were, formerly made in America. 
Verbena officinalis (Vervain, Herb of Grace).
