596 ENUMERATION OF LEGUMINOSE. 
from that of Crotalaria, but this is not a material character ; 
in a few others, the keel is acute, or even rostrate in one or 
two, but in these, the very much compressed pod, and the 
very different habit, leave no doubt as to their affinity with the 
Lotononid es, and although the keel is rostrate, the style is in- 
curved, and not geniculate, as in Crotalaria. The character 
derived from the pod is less constant; a slight compression 
may be observed in Crotalaria ramosissima, and in a few of 
the Chrysocalycinie, whilst in many Lotononides, it is decidedly 
turgid when ripe, but in these cases, the form of the keel is 
very decided. 
From Argyrolobium, Lotononis may be constantly known by 
the calyx. 
The peculiarities which have induced the approximation 
of Lotononis to Lotus, are the tendency to an umbellate inflo- 
rescence, and the unilateral solitary stipules which may be 
observed in several of the species, and are not to be found in 
Crotalaria, but these characters are not of importance, nor 
are they constant in species otherwise closely allied to each 
other. 
The following divisions, which I should propose as sec- 
tions, have mostly been established as genera, though not 
always with the same limits as here given to them. 
Sect. 1. AuLAcinTHUs. Racemiterminales. Flores parvi. 
Legumen breve, turgidum, sutura carinali subintrusa. 
Sect. 2. Kressita. Flores in pedunculis brevibus solitarii 
v. pauci in racemis terminalibus. Vexillum amplum. Carina 
obtusa. Legumen compressum v. vix turgidum, 
Sect. 3. TELINA. Pedunculi elongati uniflori v. rarius sub- 
umbellatim 2-4-flori. Vexillum amplum. Carina obtusa. 
Sect. 4. PorvrLonruw. Pedunculi elongati umbellatim v. 
subracemoso-pluriflori. Vexillum mediocre. Carina obtusa. 
Sect. 5. Oxypium. Pedunculi umbellatim multiflori ra- 
rius 1-2-flori. Vexillum mediocre. Carina acuta. 
Sect. 6. Lipozyeis. Florum capitula subsessilia termi- 
nalia. Vexillum sepius oblongum. Carina obtusa v. rarius 
acutiuscula.
