I. Whether the flowers are ^ Bisexual/ 

 II. Whether the flowers are *" Unisexual/ or 

 III. Whether the flowers are ' Mixed/ 

 By ' Bisexual' plants are imderfl:ood such, whose flowers have their Stamina and Pistilla (the 

 male and female parts of Plants) inclosed within the same corolla. 



By ' Unisexual/ such as produce flowers with the Stamina and Pistilla placed in diflerent 

 corollas 



Lastly, by ' Mixed/ is understood a mixture of the two kinds of flowers, ' Bisexual/ and 

 ' Unisexual/ 



Having made tho necessary examination, if the Sexes are ''mixed/ he is at once arrived 

 at his journey's end, his plant is of the Class XXIII. POLYGAMIA. 



If ' Unisexual/ he has one of two roads to take, 



I. The two Sexes are either ^ on the same plant,' or 

 II. The two Sexes are ' on different plants/ 



That is. Stamen-bearing flowers. (?;2^/e flowers) and Pistil-bearing flowers [female flowers) are 

 in the former instance to be found on the same plant, produced from the same root,... and in the 

 latter case, the correspondent male 2ind female flowers, are found on ^i^^rd'/z/ plants, produced 

 on different roots. 



His plant being as the directing post, he reads the botanical inscription, and discovers his 

 plant to come either under the Class XXII. ' DKECIA,' or Class XXI. ' MONGECIA/ 



But if the flower was Bisexual, he has another course to take, and he has to see, 



I. Whether the ' Anthers' are ' separate/ or 



II. Whether the *■ Anthers' are ^ united.' 



If he finds five ' Anthers united' round the Pistillum, he has reached the object of his 

 destination, namely Class XX. ' SYNGENESIA.' 



If the ' Anthers' were ' separate,' he has to advance a 'fourth stage," and to see, 

 I. Whether the ' Filaments' are ' separate/ or 

 II. Whether the ' Filaments ' are ' united with each other/ or, 

 III. Whether the ' Filaments ' are *" united with the pistillum.' 

 If the Filaments arise from any part of the Pistillum, or from a pedicle (column) elevating the 

 Pistillum, the plant is then of Class XIX. ' GYNANDRIA.' 



If the ' Filaments are united with each other/ (these being joined together with a mem- 

 brane), they are either, 



I. Afl of them united, ' forming one body/ or, 

 11. Divided into ' two parcels,' making two bodies, or, 

 III. Divided into ' three, or more parcels/ each parcel being united. 

 If united together, but forming ' three, or more parcels,' the flower falls under the Class 

 XVIII. ^ POLYADELPHIA,'...if forming ' two bodies/ under Class XVII. ^ DIADELPHIA,' 

 ...and only ' one body,' Class XVI. ' MONODELPHIA.' 



But if the ' Filaments' were ' separate/ he has to examine, 



I. Whether these are ' proportionably long,' or, 

 II. Whether these are of '' different lengths.'
