Both Ferdinand Deppe, (1832) and Thomas Nuttall, 1836, 
had familiar knowledge of the species in their Californian travels — 
about a dozen years before Theodore Hartweg came this way. 
Nuttall named the species for Deppe, it would appear. Then, 
some twenty years later, Mr. Bentham in treating of Hartweg’s 
Californian collections, named the plant R. Caléfornicus, and this 
new synonym was forthwith adopted by the American authorities, 
who thus relegated to obscurity or oblivion the true and rightful 
name. 
Dicecism in Anemone acutiloba, Lawson. — 
In the Anemone acutiloba, Lawson, there is a manifest ten- 
dency to be dicecious. A year ago a plant was found, all the 
flowers of which were strikingly different from those of other 
plants near by. The dark-blue calyx was much smaller than the 
involucre, and the stamens were wanting. The pistils 
were from thirty-five to forty in each blossom, or about 
double the average number in perfect flowers. Only abortive 
stamens were found in two of the flowers. The stamens are 
numerous in normal flowers, and on account of their absence, if 
for no other reason, the blossoms under consideration appeared 
different from the ordinary sort. In addition to the absence of 
the stamens and the small size of the calyx, there was an unex- 
‘pected development of the involucre. Instead of the ordinary 
number, there was a fuurth bract which, although green, had the 
size and shape of the sepals. It, however, occupied a position 
close by the sides of the other bracts, and made up a part of the 
involucre which, in this Anemone, is situated a half inch or more © 
below the flower. 
Another deviation noticed in the involucre, was the much 
_ greater development of one of the bracts, and the dentate or 
notched tip which it possessed. The flower under consideration 
is shown (natural size) at ain the engraving. At 4 the same 
flower is seen with the calyx laid back so as to better indicate its 
size and the appearance of the centre of the flower with its pis- 
tils only. A rear view of the same blossom is givenatc. Inall _ 
of these the exaggerated size of one bract is easily seen, as also 
the manner in which its tip is developed into three quite sharp
