The Flora of Wiltshire. 



capsule in each genus is syncarpous with ovuliferous dissepiments, 

 and is crowned with a many-rayed stigma, the number of rays cor- 

 responding to that of the dissepiments. The chief structural differ- 

 ence hitherto observed between these capsules, consists in that of 

 Nymphcea being composed of distinct carpels, surrounding the axis 

 and having the dissepiments formed by the juxta-position of the 

 ovuliferous sides of the perfect cells, with intermediate plates 

 of cellular tissue. Whilst, in Papaver, the inflected sides of the 

 conjoined carpels not being continued to the axis, the imperfect 

 ovuliferous dissepiments project only midway into the cavity of the 

 capsule, and thus leave it one-celled. The minute structure of Pa- 

 paveracece, and its relations to Nymphceacece and Ranunculacece will 

 probably form the substance of a future paper in these pages, un- 

 connected with the present series.

alluded to by this author, thus, in Nymphseaeeee " Styli .... con- 



nati stigmatibus supra urceolum peltatim (exacte ut in Papavere) radiatis basi 

 connatis apice liberis." p. 39. Again " Papaveracece accedunt hinc mediante 

 Papavere ad Nymphseaceas." p. 68. In Fl. Fran. Decandolle included Nym- 

 phcea and its immediately alliod genera in Papaveracece, in which this great 

 botanist followed the example of Linnieus, who had previously referred Nym- 

 phcea to his 27th order Phceadece, which very nearly corresponds with the 

 Papaveracece of modern authors.
