SPECIFIC DISTINCTIONS. 463 



6. Art kjulate, jointed; when it is furnished with a joint, as 

 in OxALis,...SiDA,...and Hibiscus. 



7. Coming out in pairs, as in Capraria, and Oldenlandia 

 Biflora. 



8. Tern, or three, from the same axilla, as in Impatiens Tri- 

 flora. 



9. Flexuose, bending divers ways, or Undulate, ivaved, as 

 in Air a Flexuosa. 



10. Remaining on the plant after the fructification is fallen* 

 as in J am bo lifer a,. . .Ochn a, . . .and Justicia. 



1 1. Incrassate, thickened towards the flower, as in Cotula,.., 

 Tracopogon, and most cernuous flowers. 



The parts of Fructification often furnish most certain and 

 constant specific differences. Linnaeus tells us he was once of 

 a contrary opinion ; and held, that as the flower was of shcrt 

 duration, and its parts commonly very minute, recourse should 

 not be had to the fructification for specific differences, till all 

 other ways had been tried and found ineffectual ; but as the fruc- 

 tification contains more distinct parts than all the rest of the 

 plant taken together, and certitude is found throughout nature to 

 depend mostly on her minuter parts, he has since readily ad- 

 mitted this distinction. 



In Gentiana, the species cannot any way be distinguished, if 

 the flower is not admitted as a specific character; but they are 

 easily distinguished by their corolla:, which vary in being campa- 

 niform, . . .rotute, . . . infundibuliform, . ..quinquefid, . . . quadrifd, . ..octo- 

 fid, &c. 



In Hypericum, the species are distinguished by the flowers 

 being trigynous*, or pentagynousf. 



In Geranium, the African species are distinguishable from 

 their European congeners, by the corolla being irregular, and 

 also by the connexion of their stamina.
