Order XXYII. TILIACEiE (by Dr. Maxwell T. Masters). 



Flowers reo;ular, hermaphrodite. Sepals 5 or fewer, distinct, rarely co- 

 herent, valvate. Petals 5, sometimes absent, alternate with the sepals, ini- 

 bricate, glandular or glandless at the base internally. Stamens indefinite, 

 rarely definite, inserted on a short contracted torus or on an elongated one. 

 Filaments free or more or less united below% sometimes 4-5-adelphous, all 

 fertile or some sterile. Anthers 2-celled, linear or globose, dehiscing longi- 

 tudinally or by pores. Ovary free, 2-10-celled. Style entire; stigmas 

 usually small, as many as the cells of the ovary, sometimes large ; ovules 

 anatropal, attached to the inner angles of the cells of the ovary, sometimes 

 solitary, pendulous, generally numerous, in 2 rows in each cell. Fruit 2- 

 10-celled or 1-celled by abortion, sometimes divided transversely by spurious 

 partitions, diy or fleshy, loculicidally dehiscent, indehiscent or separating 

 into cocci. Seeds solitary or few, ascending, pendulous or transverse, exaril- 

 late (rarely arillate) ; testa coriaceous, sometimes pilose. Albumen fleshy. 

 Embryo straight. Cotyledons roundish, leafy. Eadicle next to the liilum. 

 — Trees or shrubs or sometimes herbaceous plants. Leaves alternate, gene- 

 rally more or less oblique at the base, penninerved or palminerved, simple or 

 lobed, glabrous, pilose or stellate-tomentose. Stipules in pairs, deciduous. 

 Flowers cymose, lateral and terminal, rarely axillary, but often by the side of 

 the leaf. 



An extensive Order, especially abundant in the tropics. They approach Malvacece and 

 Sterculiace(B in their valvate calyx, but differ in their 2-celled anthers and generally free 

 or but slightly coherent stamens. 



The bark in many of these plants is very fibrous, even in the herbaceous species the fibre 

 is important, as in the case of "jute," the product of some species of Corchorus. The 

 same fibrous character is present to a notable extent in the fruit of some species. Many of 

 them abound in mucilaginous juice.
