lolobea, and they are divided by him into sections, viz. 1 . § Sophorese, 2 § Lo-- 
teae, 3. § Hedysareae ; the latter he designates as SarcolobetB, which compre- 
hend, 4. § Vicieae, 5. § Phaseoleae, 6. § Dalbergieae. 
Tribe 2. Swartzie^. DC. 
Calyx bladdery, with indistinct lobes. Stamens hypogynous. Corolla 
none, or petals only 1 or 2. 
RECTEMBRIJE. 
Radicle of the embryo straight. 
The tribes are known by the position of their stamens and the aestivation 
of their petals. 
Tribe 3. C^salpinie^. R. Br. 
Petals imbricated in aestivation, and stamens perigynous. 
Of the genera comprehended in this tribe, those which have petals, and 
their stamens variously combined, are called § Geoffrieae ; such as have petals, 
the stamens being distinct, are § Cassieae ; and a couple of genera, with dru- 
paceous fruit and no petals, constitute § Detarieae. 
Tribe 4. Mimose^. R. Br. 
Sepals and petals valvate in aestivation. Stamens hypogynous. 
The reader is referred to the 2d volume of De Candolle’s Prodromus for 
further information upon these divisions. 
Geography. The geographical distribution of this order has been con- 
sidered with great care by De CandoUe, from whom I take the substance of 
what follows. 
One of the first things that strikes the observer is, that if a number of ge- 
nera of Leguminosae have as extensive a range as those of other orders, there 
is a very considerable number of which the geographical limits are clearly de- 
fined. Thus the genera of New Holland are in most cases unknown beyond 
that vast island ; the same may be said of North and South America, and the 
Cape of Good Hope ; and there are between 14 and 15 genera unknown be- 
yond the limits of Europe and the neighbouring borders of Asia and Africa. 
About 92 genera out of 280 are what are called sporadic, or dispersed over 
difierent and widely separated regions, such as Tephrosia, Acacia, Glycine, 
and Sophora. The species are found more or less in every part of the known 
world, with the exception, perhaps, of the island of Tristan d’Acugna and St. 
Helena,* neither of which do they inhabit ; but they are distributed in extremely 
unequal proportions ; in general they diminish sensibly in approaching the 
pole, especially the Rectembriae, which are unknown in northern regions. This 
will be apparent from the following table : —
