POLYPETALA CALYCIFLORA. 
Calyx free or more or less adhering to the ovary. Sepals gene- 
rally more or less united. Petals in 1 or 2 whorls, unlike the 
sepals, or in 2 or more whorls, passing gradually into sepals, 
inserted on the calyx (perigynous) or on the torus (hypogynous), 
separate, rarely united, sometimes absent. Stamens definite or 
indefinite, inserted on the calyx (perigynous), or, when the ovary is 
inferior, appearing to spring from the superior margin of the latter 
(epigynous). Ovary superior, half inferior, or wholly inferior. 
ORDER XXV.—-LEGUMENIFER4. 
Herbs, shrubs, or trees, with alternate compound or decom- 
pound leaves, of which, however, the leaflets are sometimes reduced 
to 1. Stipules usually conspicuous, free, or more or less united at the 
base to the petiole or to each other. Flowers irregular or regular, 
variously coloured, sometimes solitary but more commonly in 
racemes, spikes, heads, or panicles, the inflorescence being some- 
times axillary and sometimes terminal. Sepals 5, united together 
into a 5-cleft or 5-toothed calyx, with the segments often unequal 
in size or degree of cohesion to each other, the odd one inferior or 
turned away from the axis of the inflorescence. Petals 5, some- 
times fewer or entirely absent by abortion, most commonly unequal, 
but sometimes equal, distinct or variously cohering together, the 
odd petal superior. Stamens definite (often 10, more rarely 5) or
