be admitted into it. Xylopia goes with 

 the greatest propriety to its natural allies 

 in Polyandria Polygyria, Annona, &c., 

 its short stamens being inserted into thtf 

 receptacle below the germen. Grezcia, 

 as well as Schreber s Microcos if a good 

 genus, belong to Polyandria Monogynia, 

 the organs of impregnation being merely 

 -elevated on a common stalk, like those of 

 Passiflora -&n&Ayenia. Ambrosinia, Arum, 

 and Calla, are all justly removed by Schre- 

 ber to Monoecia, though I think, for rea- 

 sons hereafter given, they are more com- 

 modiously and naturally placed in the Or- 

 der Polyandria of that Class, than in the 

 Order Monandria. Dracontiwm and Po- 

 tJios, of the same natural family, having, 

 perfect or united flowers, the former with 

 7 stamens to each, the latter with 4, are 

 undoubtedly to be referred to their corre- 

 sponding Classes, IJeptandria and Teiran- 

 dria. Zostcra, the only remaining genus 

 of Gynandria Polyandria in Linnaeus, I 

 have long ago ventured to remove to Mo- 

 nandria Monogyuia; See Engl. But, 

 t. 467.
