is valuable as a low-grade perfume oil. Brooks * says that it 

 is commercially profitable to distill the oil. He reports his in- 

 vestigation as follows: 



The leaves yielded 0.08 per cent of oil by steam distillation. On freez- 

 ing, the oil deposited 18 per cent of a white crystalline, very volatile com- 

 pound, having an odor closely resembling that of camphor. After recrys- 

 tallizing the substance twice from petroleum ether, the melting point was 

 96.5° to 97°. The compound is very unstable. A pare specimen of it 

 changed in 24 hours to a pasty mixture of oil and unchanged crystals. 

 It was not further investigated. The oil had an odor suggesting a mixture 



30 

 of camphor and lemon gi'ass. Its constants were as follows: N t-v~ 



1.4620; specific gravity, |^o 0.9059. 



The oil is largely linalool, since the fraction boiling from 195° to 200° 

 yields citral on oxidation with chromic acid mixture. 



Toddalia asiatica is a spiny, woody vine. The leaves are al- 

 ternate and trifoliate. The leaflets are pointed at both ends 

 and 5 to 8 centimeters in length. The flowers are small, 

 greenish, and borne on rather large compound inflorescences. 

 The fruits are small and are borne in fairly large clusters. 

 They are considerably less than a centimeter in diameter and 

 when dry are distinctly three- to five-angled. 



This species is common in second-growth forests and is also 

 found in virgin forests.

Genus LANTANA 

 LANTANA CAMARA L. LanTANA. 



Local names: Albahaca de caballo (Spanish in Zamboanga) ; bahug- 

 bahug (Negros) ; boho-boho (Iloilo) ; coroydtas (Manila) ; lantdna (Tarlac, 

 Cavite, Batangas, Laguna) ; tinta-tintdlinn (Manila). 



LANTANA OIL 



This species has very aromatic leaves from which Bacon t 

 obtained an oil having an odor somewhat like that of sage. 

 Concerning his experiments he writes : 



Seventy kilos of the leaves distilled vdth steam gave 60 cubic centi- 

 meters of a light yellow oil; 100 kilos gave 245 cubic centimeters, and 

 110 kilos gave 78 cubic centimeters of oil. 



These results show that the yield of oil evidently varies considerably, 

 the differences depending upon the season, age of the leaves, etc. The oil

has a specific gravity of t^ =0.9132; Nyp =1.4913; AYr=+ll-5. Its
