150 NATURAL HISTORY OF PLANTS. 
Watt." is one of the most magnificent ornamental trees known, and 
the Browneas, with their numerous coloured bracts, are not far 
behind it in beauty. It is to be hoped that the genera Afzelia and 
Berlinia may be cultivated in our hothouses, for their splendid 
corollas are exquisitely scented.’ Schotia blooms pretty often under 
our cultivation.’ Saraca is grown in the gardens of India, owing 
to the beauty of its petaloid calyx. Many yellow-flowered perennial 
Cassias are bedded out in our summer parterres. The so-called 
Flamboyants or Flame-trees of India and the islands east of tropical 
Africa, are all prized for their conspicuous red flowers. Of these 
some are true species of Poinciana,° and the remaining two are 
Colvillea racemosa,’ of Madagascar, and Cesalpinia pulcherrima,’ now 
found in all hot countries. Indeed all the arborescent species of 
Cesalpiniea are ornamental; and C. Gilliesii® often flowers in our 
gardens. Cadia varia has pretty pinkish flowers, something like 
those of the Mallow.’ Species of Cercis (Judas Tree; Fr., Gainier, 
Bois de Judée), Gymnocladus, and Gleditschia are often planted in our 
parks and gardens, and are prized, the former for their precocious 
flowers, the latter for their foliage, and the peculiar look of their 
enormous branching spines. 
Linpizy showed that the chief property of Cesalpiniee is that of 
purging.” This is especially marked in the genus Cassia,” which in 
this respect may be distinguished into two groups, Cathartocarpus 
and Senna. The former supplies us with the drug Cassia (Casse), 
the latter with Senna (Séxé). The pulp of the fruit is mainly 
used with the Cassias, especially the commonest, C. Fistula,” the 
Purging Cassia, or Pudding-pipe Tree, known in France under the
