OBSERVATIONS.- 



The genera conflituting the DMunl cwdct of Galium, Jud Ccn. 141, ire by no mcani 

 clearly difiinguifhed by author* ; nor arc ihey eafy 10 craraflcriic. on account of the uncer- 

 tainly and variablencfsof (Itc caly* and corolla, at well as o( U* number of all the parts. It ibere- 

 fore fecms (carecly poffible to find mark of d.lWiiun. except in lite llrutturc of the (lamina and 

 pillilb. My intention ii not to treat of all thefc genera at prefcnt. bul I cannot help offering a 

 lew remark on the ciTcntial characlcj of Exacum. To ibis genus then properly belongs, if!, a 

 ralvcrflupcd corolla i ad, a fimplc flyle, with a capiute fligma. (lightly cloven : gd, flraight an- 

 ihctac, hurtling longitudinally on their inftde. Exacum differ* therefore from GcntUna, in not 

 having a cloven llylc i from Swcrtia, in the want of honey-bearing pores ; from Chiora. in not 

 having a four-cleft fligma, as well u in the number of iu parts being widely different. ; from 

 Lifianihus, in not having its Itigm* formed of two flat plates ; and finally, from Chironit, in its 

 ftraight, and not fpirally twilled, anthenc To this genus probably belong many plants referred 

 lo Chirooia by Linrucus.
