as many as sepals, inserted around the base of the torus, entire or cut, aestivation 

 contorted or variousl}" imbricate, induplicate or valvate, very rarely gamopetalous 

 (Antholoma). STAMENS usually indefinite, rarely double the number of the sepals 

 (Triumfetta, Corchorus), sometimes 10-seriate on the top of a stipitiform torus and 

 distinct from the petals, sometimes covering the whole surface of a discoid torus, 

 sometimes inserted around the edge of the torus next the petals or enveloped by 

 them ; filaments free, or connate into a ring or 510 bundles, filiform, all antheri- 

 ferous, or some not (Sparmannia, Luhea, Diplodiscus, &c.), sometimes irritable 

 (Sparmannia) ; anther-cells parallel, contiguous, dehiscing longitudinally, or at the 

 top by a pore or transverse slit (Elceoearpus, Sloanea, Vallea, Aristotelia, &c.), rarely 

 divergent and confluent at the top (Brownlowia, Diplodiscus). OVARY free, sessile, 

 2-10-celled ; style simple ; stigmas as many as cells, free or connate, sometimes 

 sessile (Carpodiptera, Muntingia) ; ovules, attached to the inner angle of the cells, 

 solitary or geminate, pendulous from the top of each cell, or ascending from the 

 base ; sometimes few, inserted at the middle of the cell, sometimes numerous, 

 2-many-seriate, anatropous or sub-anatropous, raphe ventral or lateral. FRUIT of 

 2-10 cells, or 1-celled by suppression, or many-celled by false septa, sometimes inde- 

 hiscent, nutlike (Tilia), or a drupe (Grewia, Elceoearpus}, rarely a berry (Aristotelia , 

 Muntingia} ; sometimes separating into cocci (Colombia] ; sometimes loculicidally 

 dehiscent, rarely septicidally (Dubouzetia) . SEEDS solitary or numerous in each cell, 

 ascending or pendulous or horizontal, exarillate, ovoid or angular ; testa usually 

 coriaceous or crustaceous, often velvety ; endopleura sometimes hardened at the 

 chalaza; albumen fleshy, copious or thin, rarely (Brownlowia); cotyledons folia- 

 ceous, flat, entire or lobed ; radicle inferior or superior or centripetal. 



SECTION I. TILIE^l. 



Petals entire, or very rarely emarginate, aestivation imbricate, or more often 



contorted.

Luhea. *Tilia. Apeiba. Vallea. 



SECTION II. EL^OGAEPE^. 



Petals often cut, sometimes entire (Dubouzetia} or 0, usually pubescent, aestiva- 

 tion valvate or induplicate, never contorted. Stamens some in groups opposite to 

 the petals, the others solitary and alternate.

[The following tribes of this extensive family have been proposed in the 'Genera 

 Plantarum ' : 



Series A. Holopetalese. Petals usually glabrous, membranous, contracted at the base 

 or clawed, rarely notched, usually contorted.
