LEGUMINOS#-CHISALPINIE Zi. 123 
The flowers of Ladichea' (figs. 106, 107) also come very near those 
of Cassia, and may be pentamerous or tetramerous. The calyx and 
corolla are imbricated in the bud, and the posterior petal, internal in 
the bud, differs from the rest in size and colour. The number of 
stamens is reduced to two, placed close against the posterior sepal ; 
each consists of a short free filament and an elongated basifixed two- 
celled anther, dehiscing by apical pores.* The gynzceum is formed 
of an ovary containing two or three descending ovules, and surmounted 
Labichea cassioides.

by a style with a tapering stigmatiferous apex. The fruit is elon- 
gated, flattened, and bivalve, containing one or two seeds, whose 
funicle is dilated around the hilum, and whose embryo is surrounded 
by hard albumen. adichea consists of unarmed shrubs or under- 
shrubs, with imparipinnate or subdigitate leaves, which may even 
only possess one leaflet. The flowers form short racemes in the axils 
of the leaves; each flower is axillary to a caducous bract, and is 
accompanied by two sterile bractlets. The five known species are 
Australian.’ 
Very near to the flower of Cassia is that of Dicorynia,‘ with its 
five thick much-imbricated sepals, and only three (superior) petals. 
The androceum consists of only two stamens, nearly hypogynous, 
whose thick, elongated, unequally bowed, warty or rugose, extrorse 
two-celled anthers dehisce by two short subapical clefts, and are 
supported by thick filaments, one of them being much the longer. The
