456 NATURAL HISTORY OF PLANTS. 



woody, loculicidally 2-valved at apex ; endocarp subcorneous parting 

 from exocarp, 2-valved. Seeds oblong ; testa crustaceous shining ; 

 albumen fleshy; radicle of axile straight embryo terete superior; 

 cotyledons oblong flat. — Small trees or shrubs ; leaves alternate 

 petiolate unequal at base, ovate or subrotundate, crenate-dentate, 

 penniveined ; secondary venules straight subparallel to margin ; 

 stipules 2, lateral; flowers axillary or lateral on wood, spuriously 

 glomerate, few pedunculate ; bractlets few involucrant {North 

 America, Japan). See p. 386. 



93. Corylopsis Sikb. & Zucc. — Receptacle concave ; sepals 5, in- 

 serted at edge, valvate. Petals 5, obovate-spathulate perigynously 

 inserted with alternate sepals. Stamens 5, alternipetalous, peri- 

 gynous with as many alternate truncate squamules (staminodes ?) ; 

 filaments subulate ; anthers basifixed, longitudinally rimose or 

 valvicidal. Germen {Hamamelis) half superior ; branches of style 

 2, filiform, capitate at stigmatose apex. Capsule woody, 2-cuspidate ; 

 valves 2, 2-fid, sometimes with receptacle subbaccate at base ; 

 endocarp horny separating. Seeds of Hamamelis. — Shrubs ; aspect 

 and leaves nearly of Hamamelis (or Corylus) ; stipules large caducous ; 

 flower (precocious) in axillary pendulous racemes; bracts membranous; 

 inferior large {Mountainous India, China, Jajjan). See p. 388. 



94. Bicoryphe Dup.-Th. — Receptacle cylindrical; calyx sub- 

 tubulose, 4-dentate (more rarely 5 -dentate), valvate. Petals 4 

 oblong-linguiform thick. Stamens 8 ; alternipetalous sterile ; fertile 

 4 erect ; filaments thick subulate ; anthers basifixed oblong, introrse 

 completely or incompletely valvicidal. Germen adnate to bottom 

 of receptacle, 2-celled ; styles 2, simple at stigmatose apex ; ovules 

 (of Hamamelis) 2 in each cell ; one finally abortive. Capsule 

 adnate to receptacle, 2-horned at exserted vertex, septicidally 2- 

 valved ; valves afterwards split behind ; endocarp horny dividing 

 into 2-valved cocci. Seeds descending ; testa crustaceous (blackish 

 shining) ; albumen fleshy or subcorneous ; cotyledons of inverted 

 embryo subfoliaceous, recurved at edges; radicle cylindrical. — Shrubs ; 

 branches virgate ; leaves alternate or opposite, entire coriaceous ; sti- 

 pules foliaceous unequal, sometimes large, subcordate at base; flowers
