NATURAL mSTOJiY OF PLANTS. 



India, C'luiui, and Norfcli America, glabrous or hairy trees or shrubs, 

 witli persistent alternate simple leaves, possessing two lateral stipules,' 

 and Howers in pseudo-corymbs," or terminal ramified racemes, com- 

 posed of usually biparous cymes. 



S/ranrcesif/' diiiers very little in flower and vegetative organs from 

 most species of Eriohotrj/a or Photinia. The perianth and audroceum, 

 too, arc the same, but the ovary, usually five-celled, is always free 

 for a pretty large extent, and finally forms with the surrounding 

 receptacle a drupe with a crustaceous endocarp, also five-celled. 

 AVhen this truit is quite ripe each cell opens down the middle line 

 and se})arates from the central axis. The seeds then become quite 

 free ; they have tough coats surrounding a large fleshy embryo, with 

 its radicle inferior and exserted. This genus consists of a single 

 species,' a tree from tlie temperate parts of India possessing simple 

 alternate leaves. Its liabit and inflorescence are those of many 

 species of Photinia, to which genus it might perhaps be referred 

 merely as a section. 



Paphiohpisf (figs. 467, 468) comes very near the preceding genera, 

 from which it only differs essentially in the structure of its fruit and 



the way the upper part of the

 The floral receptacle is like 

 an elongated cornet or funnel, 

 of which the bottom is filled 

 (2-^'Sm Jj mm up by the ovary. Above this, 



'■ it is lined by a coloured glan- 



dular disk, which does not 

 reach its mouth, where the 

 perianth and audroceum are 

 inserted. The calyx consists of five quincuncial sepals, and the 

 corolla of as many elongated unguiculate petals, usually twisted 

 in estivation. The audroceum has often twenty stamens, and
