 usually arillate, alhuminous. Embkto dicotyledonous, minute, straight, axile. 



Stem arborescent or frutescentj sometimes climbing, rarely sub--woody or 

 herbaceous {Acrotrema, Hibbertia). Leaves alternate, very rarely opposite {Hibbertia), 

 entire or toothed, rarely pinnatifid or 3-fid ; stipules 0, or adnata to the petiole, 

 and caducons. Flowees 5 , or polygamous, rarely dicBcious, solitary, or racemose, 

 or panicled, usually yellow. Sepals 5, rarely fewer {Tetracera, &c.), or oo {Empe- 

 doclea), imbricate, persistent. Petals 5, or fewer {Davilla, &c.), alternate with the 

 sepals, hypogynous, imbricate, deciduous. ' Stamens oo, rarely definite {Hibbertia, 

 &c.), hypogynous, sometimes unilateral (Hibbertia), usually free, rarely mon-poly- 

 adelphous (Hibbertia, Candollea) ; anthers introrse or extrorse, cells linear or sub- 

 globose, adnate, often separate and overtopped by the connective, opening vertically 

 or by an apical pore. Ovaeies several, distinct or coherent, sometimes solitary (Em- 

 pedoclea, D&liocarpus, Delima, &c.) ; styles terminal or sub-dorsal, divergent ; itigmas 

 simple or sab-capitate; ovules 2 or several, 2- seriate, ascending, raphe ventral, rarely 

 solitary and erect (Schumacher ia), anatropous or half-anatropous. Carpels some- 

 times dehiscing by the ventral or dorsal suture or indehiscent, crustaceous or 

 berried. Seeds solitary or few, ovoid, arillate (except Dillenia), testa crustaceous,

PRINCIPAL GENERA. 



(.'andwllea. Dillenia. Acrotrema. Delima. 



Plibtiertia. Wormla. Tetracera. Davilla. 



Dilleniacca are more or less closelj allied to Magnoliaeea , Anonaee/s, and Manunculacece. (See these 

 families.) 



Di'toMBceffi are chiefly natives of the southern hemisphere. Tropical Amei'icaand Asia possess ahout an 

 equal numher of species; they are rare in Africa. Dillenia is confined to tropical Asia; Hibbertia and 

 Candollea are specially extra-tropical Australian. Hitherto none have heen- found in South Africa or tem- 

 perate South America. 



mileniacea; are astringent and some are so used medicinally. The fruits of a very few are acidulous ; 

 others are reputed tonic stimulants. The leaves of Davilla elliptica, a Brazilian shrub, are vulnerary ; 

 those of Curatella Cambaiba, applied to uloei-s, are detergent. Thtracera Tigarea, of Guiana and th« 

 Antilles, is a sudorific and divu-etic; a decoction of it is given for syphilis; and a vinous infusion of its 

 seeds is said to be eificacicus in intermittent fevers, chlorosis, and scurvy. The astringent bark of Dillenia 

 serrata is employed in Asia for ulcerated sores. The acid but uneatable fruit of D. speciosa serves to season 

 dishes; and a syrup of the juice of the unripe fruit allays coughs, assists expectoration, and cures angina 

 and aphthee; its bruised bark is applied as a cataplasm in arthritis, and, like that of other species, is used 

 for tanning.
