a new Genus of Plants. I.">7 



of Triurfc, also, which I possess, as well as the figures given by Mr. Mien, 

 bear all the impress of the specimens having been broken from an under- 

 ground rhizoma. 



I shall no*v proceed to characterize this little plant more particularly, be- 

 fore making any remarks upon the affinities of it and Trhtris. I have named 

 it Peltopltyllum, from the nature of its leaves. 



Peltophyllum.

 I have greatly contrasted the female flowers of this plant with those of 

 7W„r,V. m y not having found male ones prevents me from doing the same 

 with them it would be interesting to know the natnre of the stamens , hot 

 from the great similarity of the two genera in other respects, - may c.n 

 clnde that they are not very different, so far * regards structure. What h „ 

 number <U be admits of greater doubts. In Tnuns the segments of the 

 perigo, i«„ are three; and we find the anthers to be three a so, p aced oppos.te 

 the ! g Wc ts, althongh at first sight they appear to he alternate w.th them,
