80 deeply cleft. In its enlarged vesicular calyx it offers much 

 analogy with the genera Nicandra, Cacahus, Thinogeton, Ani- 

 sodus, Withania and Hypnoticum, but the former has a longer 

 and larger campanular corolla, with an erect almost entire mar- 

 gin, and a calyx with five deeply carinated angles, and five spur- 

 like extensions at its base ; the second has a more decidedly in- 

 fundibuliform corolla, resembling that oisiNolana, and an almost 

 transparent calyx marked with dark green lines ; the third has 

 a still more tubular corolla with an enlarged thickened calys : 

 Anisodus has a large deeply bell-shaped flower with rounded 

 lobes, and a vesicular thickened calyx with five large prominent 

 nervures which become woody : in Withania the corolla is nar-

an extremely short tube, and a small erect five-cleft border. 



In Physalis, on the contrary, the corolla is broadly camj)anular, 

 with a spreading pentangular border more or less entire, and 

 generally with five large coloured spots at its base. All possess 

 a swelling calyx enveloping the fruit, and Hypnoticum agrees with 

 Physalis in having stellate or brachiate pubescence. The follow- 

 ing is its emended generic character : —
