LIST OF PERFUMES, ETC., AND PLANTS WHICH AFFORD THEM. 165 
Little Dominica exports £4,000 worth of bay leaves and oil ; 
Trinidad grows ten times the quantity, none being utilised 
for export. 
Pogostemon (see Patchouli). 
Polianthes tuberosa (Tuberose).—Largely grown in South France 
for perfume, native of India. The fading flowers, like those 
of Tropasolum, have been seen to emit flashes of light at 
night. 
Primrose (Primula acaulis).—This genus of many species found 
nearly all over the world contains many with delicate odours, 
but none more delicious than our Wild Primrose, Oxlip, and 
Cowslips of the meadows. 
Rockets (Hesperis matronalis).—Well-known fragrant garden 
plant^ 
Rondoletia (Rondoletia odorata). 
Rosaceous odours.—The Eastern Attar or Otto of Roses is one of 
the most delicious and valuable of perfumes in its pure state, 
but it is often largely adulterated by the addition of Indian 
“ Geranium ” oil (Andropogon). 
Rosemary (Rosmarinus officinalis).—A very similar oil is afforded 
by Cedrela Rosmarinus of North China. 
Roses.—An enormous genus, most of which produce deliciously 
perfumed flowers. Attar de Rose from Persia, Cashmir, 
Turkestan, &c., when pure is one of the choicest and rarest of 
perfumes. It is usually, however, adulterated with Lemon 
Grass oil (see M‘Donald’s book, pp. 104-122, for a full 
list of sweetest Roses, &c.). 
Salvia rutilans (Pineapple Sage).—This is a fragrant greenhouse 
plant. Salvia officinalis is common “ Garden Sage ” used for 
flavouring. 
Sambucus nigra (Common Elder).—The leaves have an odour 
that helps to keep away flies, especially if mixed with those of 
Tansy. Flowers sweet, used for Elder-flower water. 
Sanitas.—In 1875 Mr. C. T. Kingzett, after observing the excess 
of ozone and salubrity of the air near to Pine and Fir tree 
plantations, and conceiving that this was in part due to their 
volatile oils producing peroxide of hydrogen and camphoric 
acid, formed these reagents by a process involving the 
decomposition of turpentine, and it was made and sold in 1877 
under the above name.
