432 NATURAL HISTORY OF PLANTS. 



ferous; anthers subglobose-2-dymous, introrse 2-rimose. Germen 

 inferior ; cells 3, 4, complete or incomplete ; styles as many elongated- 

 filiform, surrounded at base by a disk, thickened by degrees above, 

 stigmatose at apex or within. Ovules go , anatropous, oc -seriate, 

 obliquely imbricate, inserted on thick fleshy placentas, Capsule sub- 

 globose, corticate, tardily septicidal between styles. Seeds oo , ascend- 

 ing oblong compressed; testa membranous reticulate produced at both 

 ends beyond nucleus ; embryo axile in fleshy albumen. — Pubescent 

 or scabrous shrubs ; hairs usually stellate ; leaves opposite (subde- 

 ciduous) ovate or lanceolate, serrate exstipulate ; flowers solitary 

 axillary, or in simple or cymiferous axillary or terminal racemes ; 

 pedicels opposite (Himalaya, China, Japan). See p. 343. 



29. Philadelphus L. — Flowers nearly of Deutzia, 4- or more rarely 

 5-merous ; calyx valvate ; petals imbricate or convolute. Stamens 

 go , disk and germen of Deutzia ; placentas 3-5 ; style partite more 

 or less deeply or to base. Capsule (3-5-celled) and seeds of Deutzia. — 

 Shrubs ; leaves opposite, entire or serrate ; inflorescence of Deutzia 

 (Central Europe, Himalaya, Japan, North America}. See p. 344. 



30. Decumaria L. — Flowers nearly of Philadelphus, G-10-merous ; 

 receptacle turbinate-campanulate. Germen inferior, 5-10-celled; 

 ovules co , descending pluriseriate. Capsule subturbinate ; apex 

 crowned by thick capitate style ; pericarp fragile thin, 2-lamellate, 

 bursting between ribs and veins ; septa membranous. Seeds go , 

 albuminous (of Deutzia or Philadelphus). — A sarmentose climbing 

 shrub ; leaves opposite transparent-lineolate, petiolate, exstipulate ; 

 flowers in branching corymbiform cymes (North America). See 

 p. 346. 



31. Fendlera Engelm & Gray. — Receptacle shortly turbinate, 8- 

 ribbed. Valvate sepals 4, and petals 4, alternating inserted on 

 margin of receptacle. Stamens S, 2-seriate, perigynously inserted 

 with perianth ; filaments flat, 2-partite at apex • lobes divaricated, 

 produced beyond cuspidate anther. Germen half-superior ; cells 4, 

 oppositipetalous ; branches of style 4, stigmatose at apex ; ovules go , 

 descending. Capsule partly superior conoidal, septicidally 4-valved. 

 Seeds go, descending imbricate; testa reticulate- winged below;
