GROUPING OF THE SPECIES. 
BENTHAM’S CLASSIFICATION AND TAUBERT’S REARRANGEMENT. 
Bentham is to this day our greatest authority on the taxonomy 
of the Leguminosae and we owe to him the first attempt at a general 
revision of Lonchocarpus and its division into natural groups. In 
his synopsis of the Dalbergieae ' he brought together 46 species under 
7 heads with characters which can be stated as follows: ? 
Floral peduncles geminate or bifurcate or sometimes several to- 
gether, but not fasciculate. 
Legume thickened at the seeds along the vexillar margin; 
standard mostly silky without. ............----...--. 1. NEUROSCAPHI. 
Legume not thickened on the vexillar margin. 
Leaflets not punctate. 
Leaves softly tomentose or villous throughout......- 3. ERIOPHYLLI. 
Leaves glabrous or more or less hairy, but not tomen- 
tose or villous on both sides. 
Standard appendiculate and more or less callous 
at the base............2 2222 ee eee eee 2. DENSIFLORI. 
Standard attenuate and not callous at the base.. 4. LAXxir.ori. 
Leaflets pellucid-punctate...........-.0-...2-22-0e eee 5. Puncratt. 
Floral peduncles neither distinctly geminate nor bifurcate. 
Inflorescence a ramified terminal panicle. ...............--- 6. PANICULATI. 
Inflorescence simple, the flowers fasciculate................ 7. FascicuLatt. 
In the Pflanzenfamilien * Taubert has the following arrangement, 
which has the advantage of giving the sections according to their 
numerical order but is founded partly on a misstatement. The Neu- 
roscaphi, Densiflori, and Laxiflori, namely, have the leaflets far from 
always glabrous on the upper surface. Besides this, the more or less 
marked pubescence or silkiness of the standard is hardly a safe char- 
acter, and the distinction between the Fasciculati and Paniculati can 
be made clearer.

2 In all the following descriptions I distinguish in the inflorescence the rachis, the 
peduncles, and the pedicels, which is not exactly in accord with the usual nomen- 
clature, but simplifies the expression. The rachis is the peduncle proper, while 
what I call peduncle would be a pedicel of the first order, and my pedicels are those 
of the second order.
