CEDRELACE^. 



[Hypogynous Exogens. 



These are common to the tropics of America and India, but are very rare on the 

 continent of Afi'ica, and the adjoining islands. 



The wood of the Order is in general fragrant and aromatic. The bark of Cedrela is 

 fragrant and resmous ; that of C. Toona, and of Mahogany (Swieteuia Mahagoni) is 

 also accomited febrifugal. The former is a powerful astringent, and though not bitter, 

 a tolerably good substitute for Peruvian Bark in the cure of remitting and intermitting 

 fevers ; particularly when joined with a small portion of the powdered seed of Csesalpinia 

 Bonducella (Kutulegee of the Bengalese), which is a most powerfvd bitter. The bark 

 was used in Java by Dr. Blume, with much success in the worst epidemic fevers, 

 diarrhoea, and other complaints ; Horsfield also appUed it in various cases of dysentery, 

 but in tlie last stage, when the inflammatory sjinptoms had disappeared. The bark of 

 Soymida febrifuga, the Rohuna of Hindostan, called on the Coromandel coast the Red- 

 wood tree, is a useful tonic in India in intermittent fevers ; but Ainslie found that if 

 given beyond the extent of 4 or 5 drachms in 24 hom-s, it deranged the nervous 

 system, occasioning vertigo and subsequent stupor. It has also been employed 

 successfully in India in bad cases of gangi-ene, and in Great Britain in tj'phus fever, 

 and as an astringent. That of Khaya, the Kassou-Khaye of Senegal, is a common 

 febrifuge in the swampy districts on the banks of the Gambia. Cedrela febrifuga bark 

 is said by Blume to be employed successfully against the intermittent fevers of Java ; 

 he observes that it is tonic and useful in cases of diarrhoea, &c., but that it should never 

 be used where there is a tendency to inflammation. The bark of Chickrassia tabularis 

 has been found to be powerfully astringent without bitterness. — Roxh. Juriballi bark, 

 a Demerara product, is also supposed to belong to some plant of this Order ; it is 

 described as being a potent bitter and astringent, far superior to Peruvian bark in fevers 

 of a typhoid and mahgnant nature. It is cordial and pm'gative ; and is also a powerful 

 diaphoretic, especially if taken warm. — Hancock. An essential oil is found in Flindersia 

 and Chloroxylon, as is indicated by their dotted leaves. The young shoots of Cedi'ela 

 angustifolia have a powerful smell of Garlic, according to Ruiz and Pavou. Satin-wood 

 is the produce of Chloroxylon S%vietenia, which is one of the plants that yield the wood 

 oil of India. — Royle. Oxleya xanthoxyla, a large tree, is the Yellow-wood of New South 

 Wales. Mahogany is the timber of Swietenia Mahagoni.
