enumerated, besides being true within themselves, to a 
system where those things are placed the nearest which 
differ the least, are likewise so strictly connected with each 
other as that they cannot be transposed from the places 
already allotted to them, and formed into distinct approxi- 
mating orders, nor yet resolved into one unbroken by such 
partitions. The marks that denote the tribe throughout, 
are, a corolla (when that part is present) consisting of a de- 
finite number of equal petals inserted in a calyw of one 
piece, bearing the stamens below the points at which the 
petals are inserted ; germens bearing the style laterally, an 
albumenless seed, in which the rudiment of the future plant 
is extended in a straight line, and an alternate stipulated 
foliage. 
The various fruits of this order present perhaps the 
readiest and most instructive examples, that these climates 
can naturally furnish, of the different modifications by 
which, thro' intervening species, one form passes gradually 
into another of very distinct appearance and combination. 
By the practised observer changes on which these attend 
will have been noted in the flower, but being there less 
"Obviously expressed, the real influence and importance, 
which belong to them in the economy of the plant, will, 
in this tribe at least, be more palpably and conclusively 
demonstrated to the beginner by the conspicuous distince 
tions exhibited in fruits with which he is already familiar.
