£00 MANUAL OF BOTANY 



Division of the Order and lUustiative Genera. — The order has 

 been divided into two tribes, as follows : — 



Tribe 1. Tiliece. — Corolla with entire petals, or wanting ; anthers 



dehiscing longitudinally. Illustrative Genera : — Corchorus, 



Linn. ; Tilia, Linn. 

 Tribe 2. Elceocarjjecs. — Petals divided, anthers opening by pores 



at the apex. Illustrative Genera : — Elaeocarpus, Linn. ; 



Vallea, Mut. 



Distrihution and Numbers. — A few are found in the northern 

 parts of the world, where they form large trees ; but the plants 

 of this order are chiefly tropical, and are there found as herbs, 

 shrubs, or trees. There are about 350 species. 



Frojyerties and Uses. — In their properties the Tiliaceae re- 

 semble the Malvaceae. They are altogether innocuous, and are 

 generally mucilaginous, emollient, and demulcent. Many of 

 them also yield fibres, which are much used for manufacturing 

 purposes. Some are valuable timber-trees, and some have 

 edible fruits.
