542 CXL. STYRACE^S. 



COROLLA monopetalous or sub-polypetalous, perigynous or epigynous. STAMENS 

 inserted at the base of the corolla, free, or filaments cohering, definite or indefinite, 

 1-many-seriate. OVARY inferior or semi-inferior, of 2-5 2-many-ovuled cells; OVULES 

 anatropous. FRUIT usually fieshy. EMBRYO albuminous, axile. 



SHRUBS or SMALL TREES. LEAVES alternate, simple, exstipulate. FLOWERS 

 racerned or solitary, axillary, bracteate. CALYX 5-4-lobed. COROLLA usually 5- 

 (rarely 4-6- 7-) lobed, i.e. composed of 5-4-6-7 petals usually scarcely cohering at the 

 base, sometimes increased by an inner whorl of petals, adhering to the outer and 

 alternating with them, [aestivation various], STAMENS inserted at the base of the 

 corolla, free, or filaments cohering, 1-many-seriate, sometimes 8-10 ; sometimes 

 numerous, pentad elphous or monadelphous the longest bundles or stamens alter- 

 nating with the corolla-lobes ; anthers 2-celled, dehiscence introrse or lateral. OVARY 

 inferior or semi-inferior, 5-2-celled, cells opposite to the calyx-lobes when they equal 

 them in number ; style simple ; stigma small, capitate, lobed ; ovules geminate, or 

 many in each cell, all pendulous, or the lower horizontal or ascending, and the upper 

 pendulous, anatropous. FRUIT usually fleshy, nearly always 1-celled by arrest. 

 SEEDS 5-1, usually solitary. EMBRYO straight, in the axis of a fleshy albumen; 

 cotyledons flat ; radicle usually superior. 



TRIBE I. SYMPLOCE^E. Corolla sub-polypetalous, aestivation quincunxial. 

 Stamens 1-many-seriate lo-oo , sometimes polyadelphous, sometimes 1 -seriate, 

 almost free, usually monadelphons. Anthers ovoid-globose. Ovules all pen- 

 dulous. 



ONLY GENUS. 



Symplocos. 



TRIBE II. STYRACE.E PROPER. Corolla 5-partite, aestivation convolute or sub- 

 valvate. Stamens 1-seriate, 7-12 ; anthers elongated, adnate. Ovules, the lower 

 horizontal or ascending, the upper pendulous. 



PRINCIPAL GENERA. 

 * Styrax. * Halesia. 



[To the above A. De Candolle adds a third tribe : 



TRIBE III. PAMPHILIE^;. Corolla 5-fid or -partite, valvate. Stamens 5 or 10, connate at 

 the base and adnate to the corolla ; anthers elongate, tubular above. Ovary free ; ovules erect, 

 unatropous. South American trees. Pamphilia, Foveolaria. ED.] 



Styracees are near Ebenacea (see that family). There is also an affinity between Symplocea and 

 Camelliaceee ; both have a woody stem, alternate leaves, sub-polypetalous or polypetnlous corolla, and 

 imbricate aestivation ; the stamens are numerous and many-seriate, and the filaments polyadelphous ; and 

 in some genera of Camelliacea the style is simple, the ovary semi-inferior, and the embryo albuminous. 

 Styraeece proper present some analogy with Philadefpheee, in the woody stem, axillary and terminal 

 flowers, free or nearly free petals, numerous stamens, inferior and many-celled ovary, and albuminous mid 

 axile embryo ; but in Philadelphea the leaves are opposite and the fruit capsular.
