The Arum triphyllum is faid by Linn.eus, who confidered 

 the genus as gynandrous, to be monoecious, bearing male and 

 female flowers from the fame root on different (talks ; we ap- 

 prehend however that this is a miftake, and that it is really 

 dioecious, the male and female flowers rifing from different 

 roots ; as has certainly been the cafe in fuch as we have feen. 

 Our plant is female, bearing a number of germens, each fur- 

 mounted by a white ftigma, crowded together at the bafe of 

 the fpadix. Above theie are a few fcattered, irregular, anther- 

 like mafles, but which do not appear to contain pollen, and as 

 the fame are found above the ftamens in the male plant, they 

 may perhaps be confidered as nectaries. 



The footltalk of the leaf and fcape are involved in two or 

 three truncated (heaths of a pale colour fpotted with purple, 

 the former exceeding the latter in length, fo that the leaf ftands 

 over the flower, like an umbrella. In our plant the leaflets 

 were not quite entire ; the margins being fomewhat undulated 

 and repand, which gives them the appearance of being (lightly 

 toothed, but they are not really fo. Native of North-America 

 from Canada to Carolina. Probably the Brafilian plant may 

 not be the lame fpecies. The roots are apt to perifh from the 

 heat of the fun in dry weather unlefs planted in the lhade and 

 a moift foil, and in fuch fituations they are liable to be de- 

 stroyed in the winter ; it will be therefore fafeft to take them 

 up after the leaves decay, and keep them in fand till the fol- 

 lowing fpring. Flowers in May. Communicated by Meffrs.
