scending ovules, whose micropyles look upwards and outwards. The 
fruit is a shortly-stipitate compressed indehiscent pod, containing 
one or two large seeds, whose embryo has a straight radicle and 
broad foliaceous cotyledons, cordate at the base. Sclerolobium consists 
of half a score species of trees from Brazil and Guiana.' They have 
alternate imparipinnate leaves, with stipules which vary greatly in 
size, and which may be simple or trifoliolate. The flowers are small 
and very numerous, in numerous racemes which are often much 
ramified. Hach flower is axillary to a caducous bract. 
Diptychandra’ has the flowers of the section Cosymbe of Sclero- 
lobium. The imbricate sepals are all nearly equal, and are inserted 
on the rim of a hollow obconical receptacle. The staminal filaments, 
too, are bent on themselves in the bud, and the stipitate pauciovulate 
ovary is surmounted by a style which is hollowed out at its truncate 
apex. The fruit is a flattened bivalve pod, containing one or more 
seeds which are flattened out transversely and attached to the peri- 
carp by one of their edges, just as in Mematoxrylon; and a mem- 
branous wing formed by the extension of their coats runs all round 
them. The broad flattened embryo, with more or less deeply 
auriculate cotyledons, is exalbuminous. Two or three species of 
Diptychandra are known, trees or shrubs from Brazil and Bolivia,’ 
with pinnate leaves and flowers in axillary or terminal racemes. 
Peppigia' has not only the vegetative characters of Diptychandra 
and Sclerolobium with the flowers in compound terminal racemes, but 
the same floral receptacle, the same centrally inserted gynzceum,’ 
the same corolla and disk. The calyx, however, divided above into 
five slightly imbricate lobes, is continuous and gamosepalous below. 
The staminal filaments are erect: and straight, not bent in the bud. 
The ovules are numerous; the style is truncate, not dilated, at 
its stigmatiferous apex. The fruit is equally characteristic: it has 
a slender foot, and is a flattened elongated membranous leaf-like 
many-seeded pod, probably indehiscent. Its placentary margin is

5 The foot bearing the ovary dilates gradually 
down towards its base; but we have seen it in- 
serted in the very bottom of the ovary, contrary 
to the description of authors.
