lanceolate-acuminate, usually nearly as long as the fruiting pedicels, 
but occasionally much shorter. Pedicels much thickened at the tip

white; upper petal rather broad, keeled, subacute, with ‘broad wings 
reflexed upwards and reaching its apex, the wings externally dark 
purple below, with well- marked whitish margins before fertilization; : 
lower petal with green keel and broad, whitish, spreading or slightly 
deflexed wings, which extend to its apex; inner petals curved up- 
wards, obtuse, apiculate, tipped with dark purple. Sepals 4-54 mm. 
long and 2-3 mm. broad, ovate, acuminate, frequently irregularly 
incise-dentate towards the base, white, with greenish dorsal nerve, 
at least as broad as the corolla-tube. Fruits large, subrotund, 
smooth tse! pointed when fresh, with an inconspicuous ~~ slightly 
narrower than the tip of the pedicel ; when dry, coarsely but not 
deeply tubercular-rugose and distinctly keeled-compressed, with two 
shallow apical pits, and the keel drawn into a very short, blunt beak, 
which is notched at maturity. 
. occidentalis is most nearly allied to F’. agrarta Lag., and may 
be considered somewhat intermediate between that species and F’ 
flabellata Gasp. From F’. agraria it is distinguished chiefly by its 
mucli larger sepals, ata instead of being lanceolate, are ovate, 
and fully as broad as the corolla-tube. The upper petal of I’. agraria 
also differs in being more obtuse and rounded, and in the absence 
of the dark purple colour ~~ the outside of the wings which charac- 
terizes the other. The s of the two species are very similar, 
ose of I’. occidentalis cain ing, on the average, a little more com- 
pressed and a little less strongly beaked than om = of F. agraria, 
while in both the mane of rugosity seems ewhat variable. 
Moreover, while in rampant forms of F. pee et the perise 
pedicels become sexed and slightly deflexed, in F’. agraria, so far 
as I se aware, ee are invariably straight. 
m I’, flabellata Gasp., which has the aspect of a fine F. 
capreotalie with br mi winged pe petals and fruits rugose when 
dry, the present species may be separated by several well-marked 
— es. Its peduncles are sicatiy ats shorter, though a trifle longer 
than in F’. agr wth and the fruiting pedicels are always less pepe: 
lis ‘iodees are still larger, and appear lighter in colour, owi 
the upper as well as the inner petals of I’. flabellata —- aunt: 
tipped with dark purple, while in F’. occidentalis a purple spot only 
is seen on the upper petal. The sepals of the two = some 
degree of resemblance, but are thinner, more toothed, more 
acuminate in F’, occidentalis. In respect of fruit, the rei species 
are widely different, that of I’. flabellata being much smaller an 
more obtuse, its profile Se that of F. capreolata, and qui
