apiculate. In C. agatiflora, Schweinf., and its allies the four upper lobes 
are connate in two pairs. Sometimes the calyx is more or less bilabiate, as in 
Sect. Chrysocalycins. C. Seemeniana, Harms, has curious broad upper lobes. 
In C. platyealyx, Steud., the upper lobes are foliaceous. The petals vary 
much in size, and, the carina especially, much in shape. In C. minutissima, 
Bak. fil., and C. bongensis, Bak. fil., the flowers are 35-5 mm. long, while 
in C. agatiflora, Schweinf., and its allies the flowers are 35-55 mm. long. 
A point of considerable interest is that the same type of flower is associated 
with the same type of pod: thus the type of flower of C. agatiflora with 
large flowers, with obliquely rostrate carina considerably longer than the 
ale, is always associated with a very longly stipitate pod, while in C. laehno- 
carpa, Hochst., with which I have associated C. elata, Welw., we have quite 
a different type of flower ; the carina is dorsally rounded, the rostrum much 
shorter, and flowers of this type are associated with sessile or subsessile, 
oblong or oblong-cylindrical pods, densely clothed with a thick tomentum. 
Then we have the type of flower of C. polysperma, Kotschy, with a long 
calyx with conspicuous bracteoles at the base, the teeth being much longer 
than the tube, the corolla about equalling the calyx ; this type of flower is 
always associated with a very hairy, or pilose, egg-shaped pod. A very 
common type of flower in this genus is one in which the petals are distinctly 
longer than the calyx, the conspicuous feature being that the carina is bent 
dorsally at an angle approaching a right angle, the rostrum is long and 
straight, the pod is sessile or shortly stipitate, and if the flower be small it 
is generally globose or subglobose, if larger the pod is generally egg-shaped. 
Again we have the type of flower found in C. glauca, Willd., where the petals 
are distinctly longer than the calyx, the carina is dorsally rounded, the standard 
is recurved; this type of flower is associated with a linear-oblong stipitate 
pod. In C. farcta, R. Br., the corolla is yellow, longer than the calyx, the 
carina dorsally rounded, the pods in this species and its allies are slightly 
curved, and the seeds inside are embedded in silky hairs or wool. In the 
group characterised by the type of flower found in C. intermedia, Kotschy, 
and its allies the pods are cylindrical or oblong-cylindrical. 
The bracts and bracteoles are usually small, and the bracteoles are either 
situated on the calyx or on the pedicel. In C. polysperma, Kotschy, and its 
allies the bracteoles are conspicuous. In C. platycalya, Steudel, there are 
two large ovate bracteoles below the calyx. Rarely, as in C. grandibracteata, 
Taubert, the bracts are large. In the Sect. Chrysocalycin: the bracteoles 
are narrow and conspicuous. 
The flowers are generally arranged in lateral or terminal racemes which 
are either dense or lax, sometimes short, sometimes long. In some species the 
flowers are in densely flowered capitula; more rarely the flowers are solitary 
or geminate at the end of a long peduncle. It does not seem advisable to 
retain the Sect. Oliganths», as the exact limits are most difficult to define
