CLASSIFICATION. 9 
of these authors, since it includes the monadelphous Species that have wing-petals like 
those of the isodiadelphous ones. Within 518504 we find two sections—(1) Triplolemea, 
which is practically identical with the Triptolemea of Bentham, Baillon and Taubert, 
deviating only in the inclusion of a group of species with small flowers and short 
styles that are by these authors relegated to their Sissoa ; 
; and (2) Podiopelalum, of 
which D. armata from Africa may be taken as typical, but which also includes 
D. Sissoo itself. Under AMERIMNON again we find three sections— 3) Endespermum, 
of which 2, tamarindifolia may be considered typical, and which as a genus was well 
'haracterised by Blume; (4) Miscolobium, of which the American D. foliolosa and 
the Asiatic D. velutina may be considered gool representatives; lastly, (9) Daibergaria, 
which, save for the inclusion of a few Selonolobit, is exactly the section of this name 
as characterised by Bentham. 
The arrangement now adopted the writer believes to be more natural, and finds 
to be certainly more convenient than any system hitherto suggested. It has been 
arrived at, not by the method of adopting arbitrary characters and subdividing the 
genus according to these, but by the opposite method of first throwing the different 
species into small groups of closely allied forms, and subsequently bringing together 
the more closely allied of these apparently natural groups. The method 
an amplification, in the light of the evidence afforded by fuller and more complete 
suites of specimens, of the Benthamian method; the underlying motive is the same— 
to facilitate the identification of the species, An examination of the often complex 
Synonymy will show how necessary some such modification is; whether the system 
now proposed will stand the test of further discovery and investigation is a point 
that can only be tested by experience. In the accompanying sheet (Рглтв 1) is 
exhibited a schematic view of the disposition of these natural groups with reference 
to each other and to the subgenera and sections to which they severally belong. The 
unbroken lines mark the sectional limits; the dotted lines show the cleavage that 
artificially separates the Selenolobia and LEvastaphylia. Тһе relative position of the
