 8. 407. 



Diagnosis.— Solanal Exogens, with 5 free stamens, axik placenta, aud leafy cotyledons, 



folded longitudinally. 



Trees. Leaves alternate, scabrous, without stipules, of a hard harsh texture. Flowers 

 panicled, never gyrate, with minute bracts. Calyx inferior, 4- 5-toothed, ribbed in 



most cases. Corolla monopetalous, 

 4- 5-cleft, regular, imbricated. Sta- 

 mens alternate with the segments of 

 the corolla, out of which they arise ; 

 anthers versatile. Ovary superior, 

 4- 8-celled, with 1 pendulous, anatro- 

 pal ovule in each cell ; style conti- 

 nuous ; stigma 4- 8-cleft, with recurved 

 segments. Fruit drupaceous, 4- 8- 

 celled ; part of the cells frequently 

 abortive. Seed pendulous from the 

 apex of the cells by a long funiculus, 

 upon which it is turned back ; em- 

 bryo inverted, with the cotyledons 

 plaited longitudinally ; albumen ; 

 radicle superior. 



The plaited cotyledons and dicho- 

 tomous style first led to the separation 

 of this Order from Borageworts, 

 with which it was formerly associated, 

 chiefly, it is to be supposed, on ac- 

 count of the roughness of the leaves. 

 Von Martins remarks, that it is in 

 fact much nearer Bindweeds, from 

 which it differs in its inverted embryo 

 ^ and drupaceous fruit. Nevertheless, 

 ML Alph. De Candolle has reverted 

 to the old opinion, and admitted it as 

 the first tribe of his Borragineae. I 

 confess, however, that it seems to me 

 impossible to admit Sebestens even 

 into the same category as Borage- 

 worts, the indispensable peculiarities 

 of which arc a gyrate inflorescence, 

 and nucamentaeeous fruit, neither of 

 which circumstances occur here. 



The species are, for the most part, 

 natives of the tropics of both hemi- 

 spheres. A few occur in the cooler 

 parts of South America. 

 The flesh of their fruit is succulent, mucilaginous, and emollient, as is seen in Cordia 

 Mvxa and latifolia. They are believed to have been the Persea of Dioscorides. The 

 sniell of their nuts when cut is heavy and disagreeable, the taste of the kernels like that 

 of fresh filberts. They are the true Sebestens of the European Materia Mediea, but ac- 

 cording to Roxburgh, are not used in the Northern Circars of India, for any medicinal 

 purpose. When ri~pe they are eaten by the natives, and also most greedily by several 

 sorts of birds, being of a sweetish taste. Cordia Rumphii has a brown wood, beautifully 

 veined with black, and smelling of musk. The timber of C. Gerascanthus, called Bois 

 de Chypre, and Spanish Elm, is of some importance in the West Indies.
