 ovary {inferior), it is tubular and somewhat inflated. The corolla is compound of united petals (gamo- 

 petalous), it is funnel-shaped, with a long tube enlarged above, the limb is spreading and has 5 lobes 

 which are folded in plaits in the bud {plicate), There are 5 stamens, attached to the corolla {epipetalous) 

 below the middle of the tube ; the filaments reach to about the end of the corolla-tube. The pistil is 

 composed of 2 coherent carpels {syn-carpous) ; the ovary is 2-celled ; the ovules are numerous ; the 

 ovule-bearing surfaces {placentas) are on the partition (or septum) between the cells, and are so large as 

 nearly to fill up the interior ; the style is filiform, and about as long as the stamens ; the stigma is 

 2-lobed. The fruit is dry and splits up {a capsule) through the septum (septi-cidal dehiscence) from the 

 top into 2 valves, which again split on the inside ; it is 2-celled and covered below by the dry per- 

 sistent calyx. The seeds are very numerous, and small ; the embryo is slightly curved in the axis of 

 the endosperm. The Tobacco plant is a herb, covered with glutinous hairs. The leaves are alternate
