DARLINGTONIA CALIFORNICA. . 7 
the genus Moneses (Pyrola uniflora, Linn.) ; in addition to which, it may be , 
remarked that the seeds of Heliamphora are furnished with a loose winged testa 
and a minute embryo, as in Pyrolacee. Between Moneses and Darlingtonia the 
comparison may be drawn still more closely: in the floral envelopes and the 
almost definite stamens, in the structure of the ovary and in the radiating stigmas, 
as well as in habit, the likeness of our new genus to Moneses is quite remarkable. 
In many points, too, we may trace in Darlingtonia an approach to Monotropa, of 
the nearly related family Monotropacee. Heliamphora, in its several-flowered 
scapes, is more like Pyrola. The singular pitchers of Sarraceniacee might seem 
to show a wide difference between the families thus compared, but characters 
drawn from the abnormal condition of a single organ are not of high importance in 
determining affinities. In conclusion, I would remark that, while offering a few 
additional considerations that seem to strengthen the views of M. Planchon, I do 
not wish to be considered as yet adopting those views. When we obtain the fruit 
of the Darlingtonia, perhaps it may give us some better knowledge of the place 
that its family should occupy in the Natural system.
