60 APPENDIX. 



the berry is small, seated in the broadly campanular expanded 

 calyx, containing few seeds, which are proportionally large, 

 somewhat conchoid, the embryo of more than a circle, being 

 spirally helical : in Hypnoticum the berry is larger, generally of 

 a bright scarlet colour, 2-celled, filled with very numerous small 

 seeds, which are reniform and compressed, with a spiral and 

 nearly annular embryo ; the cotyledons, equal in length to the 

 terete radicle, are subdilated and accumbent. These differences 

 are sufficiently evident and numerous enough to constitute a 

 wide generic distinction — the affinity of Hypnoticum being much 

 closer to Physalis, from which it differs in its much smaller 

 corolla and the adnate placentation of its seeds, 



M. Dunal has formed another section of Withania out of the 

 Funeeria coagulans (Stocks), a plant extremely different from the 

 former genus ; in habit and structure it more nearly approaches 

 Hypnoticum, resembling it greatly in the form of its flowers : 

 the calyx, however, instead of becoming inflated to a larger dia- 

 meter than the berry, and reticulated and vesicular, in Puneeria 

 invests it closely, remaining opake and tomentous, destitute 

 of visible nervures, brittle, and of the texture of tender paper. 

 Its flowers are dioecious, a rare occurrence among the Sola- 

 nacece} the corolla is tubular, scarcely funnel-shaped, with a 

 narrow border of five short reflexed teeth : the whole plant is 

 covered with dense tomentum consisting of stellated brachiate 

 hairs, as in Physalis and Hypnoticum : in these features there is 

 little in common with Withania. 



Larnax differs from Withania in its herbaceous stems and fas- 

 ciculated axillary flowers, in its minute urceolate calyx with five 

 short blunt teeth, which increases in size with the growth of the 

 fruit ; it is of thin texture, becomes inflated and globular, closely 

 investing and concealing the berry, its mouth being much con- 

 tracted and tubular, as in Margaranthus. The corolla is some- 

 what bell-shaped, with a border equal in length to the tubular 

 portion, divided into five expanded oblong segments : its stamens 

 have capillary filaments. One species is made to form a section 



M 



Withania by M 

 to hold little resemblance to that genus. 



The remaining species before alluded to, included b 

 in Withania y may therefore be thus disposed of; viz. 



1. Withania somnifera^ Dun. is Hypnoticum somniferum, Rodr. 



2, Morrisoniy Dun. = Larnax Morrisoni, nob. Agreeing with 



this genus in its numerous fasciculated 

 flowers, its small urceolate calyx and 

 red berries enclosed in an inflated calyx, 

 and in the country of its origin : its 

 characters are quite at variance with 

 Withania,
