Thus it is seen that Grabowskyee stand in relation to 
Nolanee, in the same position that Dichondree do to Convol- 
vulee, and although the former, in respect to Solanee, are 
placed at the two extreme points of the class Tubulifiore 
Endl., it cannot be denied that these Orders offer many ana- 
logies common to each other, for Grabowskya has quite the 
habit and inflorescence of Lycium, and Nolana is not very 
dissimilar in habit from Physalis, and other Solanaceous 
plants ; still the carpological characters of the Nolanacee 
seems so very distinct, verging evidently towards Ehretiacee, 
that there appears to me ample reason for justifying the ar- 
rangement above proposed, which also. offers the advantage 
of conciliating the very opposite views of our most distin- 
guished Botanists in regard to these plants. 
METTERNICHIA. 
This genus was proposed by Dr. Mikan for a beautiful 
shrub, with large white flowers from the neighbourhood of 
Rio de Janeiro, and by him dedicated to Prince Metternich, 
the liberal patron of the many scientific expeditions that 
have so greatly extended our knowledge of the Natural 
History of Brazil. It comprises only a single species, of 
which a very good figure was published by Dr. Mikan in his 
Delect. Flor. et Faun. Braz. 3, tab. 1, but as that work 
is extremely scarce, and the details of the seeds not quite 
perfect, I offer the results of my own observations.
