A figure, attributed to this species, is given by Dahlstedt, in which 
the fruit is ovoid, with a small conical style not unlike that oiP.pavvi- 
folia. The fruits of the specimens at Berlin are not quite ripe, but they 
are more or less globose with a fairly long cylindrical style, and appear to 
agree with those of P. claytonioides . It seems therefore probable that there 
is some mistake about Dahlstedt’s figure. 
P. pinulana, C. DC. (descr. emend.).
