that without violating the connexion already established by 
the authority of the most distinguished Botanists, between 
Dichondree and Convolvulee, they will stand after Borraginee, 
and before Convolvulee through the intermedium of Dichon- 
dree. 
The new genera of Nolanacee, proposed as before alluded to 
by Doctor Lindley, although not so well distinguished by 
characters derived from the inflorescence, are nevertheless 
well marked by a distinct and peculiar habit, aided by diffe- 
rences of structure in the fruit. Most of the species com- 
prised under Nolana and Sorema, are succulent prostrate 
plants with broad fleshy leaves; in the latter genus, the 
leaves are geminate, the inner one petioled, the outer one 
sessile, with one of its margins decurrent on the stem. The 
species included by Alona, Dolia and Aplocarya, are mostly 
erect plants with a shrubby habit, and approximate or fas- 
ciculated linear leaves, many of them being densely covered 
with tomentum; the flowers of the two last mentioned. 
genera are proportionately very small, those of the others 
presenting large campanulate flowers, resembling those of - 
Convolvulus. It is worthy of remark, that all the plants —— 
of this order, grow either within reach of the humidity of 
the sea, or in inland tracts where the soil is impregnated with 
particles of salt or natron. The genus in which the plant 
about to be described is placed may be thus defined.
