he has given on the divisions of this order in the Botanical 
Register for Sept. 1844, tab. 46. Although much additional 
knowledge has thus been afforded, the real limits of Nola- 
nacee are not yet fully defined, and the true place of its 
arrangement in the Natural system not yet quite agreed on. 
Dr. Lindley, in the last edition of his “ Natural System,” 
p- 229, places it near Convolvulacee, with which it accords in 
its expanded funnel.shaped plicated corolla. Others have 
combined it with Borraginee, with which it agrees in having 
a plicated corolla, included stamens, and distinct nuts. Prof. 
Endlicher, in his Genera Plantarum, p. 655, following nearly 
the views of Dr. Lindley, places it as a sub-order, or rather 
as an aberrant group “ Convolvulaceis affinia.” After a careful 
examination of its relations, I venture to suggest for it a 
distinct place in the system, at the beginning of the class 
Tubulifiore of Endl., immediately following the Borraginee, in 
the Nuculifere of that eminent Botanist, so that intermediate 
with Convolvulacee, the Nolanacee will thus retain their close 
affinity towards Solanaceae, for it is especially with Petunia, 
&c., that they agree in their convoluted and deeply plicated 
corolla with unequal included stamens, and not less with 
many others among Solaneæ in their geminate or fasciculate 
leaves and general habit; and while they also accord in the 
annular filiform shape of their embryo, enveloped in albumen, 
and in the position of the radicle, they differ from the whole 
of that order in the origin and development of their distinct 
carpels, for the ovules of Solanaceæ are invariably attached 
to the dissepiment of a 2. celled or imperfectly 4-celled ova- 
rium. With Borraginee, on the other hand, they agree in 
the gynobasic insertion of their distinct ovaria upon à fleshy * 
lobed disc, and in their separate huts, with a single seedin — 
each cell, perforated at the base, but whether the " 
process, which I have shown to exist in all the Nolanaceé,
