remote from the hilum. This observation must, however, be understood to 

 refer only to some particular cases in Leguminosse, and also to the fructi- 

 fication ; the want of stipula? and regular flowers being usually sufficient 

 to point them out. From Anacardiaceaj and other Terebintaceous orders 

 they are at once known by the total want of resinous juice. 



Geography. All found in the tropics of Asia, Africa, and America. 



Properties. Unknown. ^. 



Examples. Connarus, Omphalobium.

Dec. Prodr. 2. 81. (1825.) 



Diagnosis. Polypetalous dicotyledons, with definite hypogynous sta- 

 mens, anthers bursting by longitudinal slits, distinct simple carpella, exsti- 

 pulate dotted leaves, and no albumen. 



Anomalies. 



Essential Character. — Calyx small, regular, persistent in 4 divisions. Petals 4, 

 hypogynous, with imbricated aestivation. Stamens doulde the number of the petals, hypo- 

 gynous. Ovarium superior, 1-celled, seated on a thickened disk; stiyma sessile, capitate; 

 ovules 2, pendulous. Fruit indehiscent, sub-drupaceous, 1-seeded, glandular. Seed with- 

 out albumen ; cotyledons fleshy ; radicle superior, very short. — Trees or shrubs, abounding 

 in resin. Leaves opposite, compound, with pellucid dots. Inflorescence axillary and 

 terminal, panicled. Pericarpium covered with granular glands, filled with an aroma- 

 tic oil. 



Affinities. The general structure of this order is that of Anacar- 

 diacesc, but in qualities it more nearly resembles Burseracece. M. Kunth 

 suggests its relation to Aurantiaceae, to which its dotted leaves, capitate 

 stigmas, and pericarpia filled with reservoirs of oil, appear to approximate it. 



Geography. Natives exclusively of the tropics of India and America, 

 with the exception of one species found in Florida, 



Properties. Fragrant resinous shrubs. The Gum Elemi Tree of 

 Nevis is, according to Dr. Hamilton, a plant related to the genus Amyris, 

 which he calls A. ? hexandra. Prodr. Fl. Ind. 35. The gum-resin, called 

 Bdellium, is probably produced by a species of Amyris, the Niouttout of 

 Adanson, according to Virey. Hist. Nat. des Med. 291. The layers of the 

 liber of a species of Amyris were found by M. Cailliaud to be used by the 

 Nubian Mahometans as paper, on which they write their legends. Delile 

 Cent. 13. Amyris toxifera is said to be poisonous. Dec. Resin of Coumia 

 is produced by A. ambrosiaca. Ibid.
