lodged inside the receptacle and covered with a glandular disk, is 

 divided into three or four cells, surmounted by as many styles 

 stigmatiferous at the apex. In the ventral angle of each is a thick 

 placenta covered with anatropous ovules. The fruit is a septicidal 

 capsule opening above into three or four valves. The seeds are 

 numerous and oblique ; the membranous outer coat is prolonged above 

 into a wing, below into a sort of tube. In the centre is an embryo 

 surrounded by fleshy albumen. Beutzia comprises six or seven 

 species' of shrubs from Temperate India, China, and Japan. Their 

 leaves are opposite, simple, serrate, exstipulate, often covered with 

 simple or stellate hairs. The flowers are grouped into simple or 

 compound spikes or racemes, axillary or terminal, with opposite 

 bracts ; more rarely they are solitary in the axils of the leaves. 



Philadelphus (the Syringa 2 of our gardeners ; figs. 397-403), may 

 be defined as Beutzia with flowers more frequently tetramerous than 

 pentamerous, a twisted corolla, and numerous stamens in four 

 bundles superposed to the sepals. The filaments have no lateral
