XCVII. LYTHRARIE^E. 433 



glandular, always exstipulate. FLOWERS , regular, or rarely irregular (Cuphea) , 

 solitary in the axil of the leaves, or fascicled or cymose, sometimes spiked or 

 racemed, and accompanied by floral bracteiform leaves, rarely panicled, peduncle 

 and pedicels 2-bracteolate at the base, middle or top. CALYX free, persistent, 

 tubular or campanulate, rarely urceolate, 3-many-toothed ; tube usually ribbed 

 with nerves, straight or rarely oblique, or gibbous or sub-spurred at the base 

 (Cuphea) ; limb more or less deeply toothed, teeth sometimes 1 -seriate, equal, 

 valvate in bud, sometimes 2-seriate ; the outer alternate, narrower, incumbent on 

 the commissure of the valvate inner ones. PETALS (rarely 0, Peplis, Abatia, &c.) 

 inserted on the top of the calyx-throat, equal in number and alternate with its inner 

 teeth, sessile or clawed, obovate or ovate or oblong, equal, or the dorsal very rarely 

 larger, imbricate in bud, often folded, waved on the edges (Lagerstroemia)^ spreading 

 after flowering, deciduous or fugacious (Sujfrenia, Peplis). STAMENS inserted on 

 the calyx-tube above its base, continuous with its nerves, equal in number and 

 alternate with the petals, very rarely less numerous (Swffrenia), very often double or 

 triple (Dodecas, Antherylium-, Lagerstroemia), 1-several-seriate, included or exserted, 

 equal or unequal, all fertile, or rarely some sterile ; filaments filiform, free ; anthers 

 introrse, 2-celled, orbicular or ovoid or oblong, erect or incumbent, dorsifixed, dehis- 

 cence longitudinal. OVARY free, sessile or shortly stipitate, rarely girt at the base 

 with a fleshy ring, or accompanied by a unilateral gland (Cuphea}, 2 6-celled, some- 

 times sub-1-celled by failure of the septa (Diplusodori) , or completely 1-celled 

 with parietal placentation (Cryptotheca) ; placentas attached to the middle of the 

 septum, or the inner angle of the cells, or uniting the base of the semi-septa ; style 

 terminal, simple, more or less long ; stigma simple, obtuse or capitate, rarely 

 emargiiiate or bilobed ; ovules usually numerous, ascending or horizontal, anatropous. 

 CAPSULE membranous, or rarely coriaceous, woody, crowned by the persistent or 

 accrescent calyx, 2-several- (rarely 1-) celled, bursting irregularly or by circumsciss, 

 or by regular semi-septiferous valves, the placentas remaining united in a free 

 column. SEEDS usually numerous, ovoid-angular, cuneiform, piano-compressed, 

 or edged with a membrane (Lagerstroemia) ; testa coriaceous ; hilum marginal or 

 basilar. EMBRYO exalbuminous, straight; cotyled&lis sub-orbicular, plano-convex, 

 2-auricled at the base, rarely semi-cylindric or convolute ; radicle short, near 

 the hilum.
