308 MR. H. W. PUGSLEY : A REVISION OF THE 
F. abyssinica, and are generally obscure in F. indica and F. Schrammii, 
while in F. Vaillantii the dark colouring is fairly distinct in some forms 
and quite absent in others. 
In F. parviflora the normally white corolla usually shows a small external 
bloteh only of purple on the wings of the upper petal, recalling the coloration 
of F. occidentalis; and in F. asepala the purple tinting, if present at all, is 
confined to the tips of the inner petals. 
* Series Ambigua. 
Flores rosei, 5-7 mm. longi; sepala 1:5-2 mm. longa; petali superioris 
ale sursum reflexe vel obsolescentes deflexæ.

There is good material in Herb. Mus. Brit. of. the plant on which this 
species was founded. As pointed out by Haussknecht (/.c.), the fruit is 
scarcely obtuse, as stated in Hammar’s diagnosis, but rather mucronulate 
when young, and at maturity subacute and very shortly apiculate, much as 
in some forms of F. parviflora, though the keel is less marked than in that 
species. In the Eritrzan exsiccata a somewhat more rounded-obtuse, though 
still apiculate form prevails. The fruit is 2-2:25 mm. long and about 
equally broad, with very shallow apical pits. 
It may further be remarked that the leaf-segments in F. abyssinica are 
more generally linear-oblong than oblong-lanceolate ; and the racemes, which 
are usually sub-12-flowered in Schimper's examples but show as many as 20 
flowers in the Eritrean exsiccata, are much longer in fruit than the very 
short peduncles, except occasionally when shade-grown. The bracts seem 
to be relatively broad—linear-oblong rather than linear—and fully as long 
as the short (2 mm. long), suberect pedicels. The ovate, acuminate sepals 
are about 1°5 mm. long and 1 mm. broad ; the purple wings of the obtuse 
upper petal are reflexed upwards as in X. officinalis or in F. Sehleicheri, but 
are normally rather narrow and scarcely cover the keel ; and the lower petal 
appears less distinctly spathulate than in most of the other species of the 
subsection. 
In the Arabian specimen at Kew the wings of the outer petals are but 
little developed, and the obscurely apiculate fruit is more rounded-obtuse 
than in the Abyssinian type.
