of showy flowers of Poinciana ; but the calyx is very peculiar ; 

 it is thick, coriaceous, and sac-shaped, divided above into four 

 valvate teeth of which the posterior one represents two sepals, 

 and is hence larger than the rest. The whole calyx comes off at 

 the base in a circular piece. The corolla resembles that of Cavil- 

 pinia, except that the vexillary petal, closely overlapped in the bud. 

 is much larger than the others. The androceum consists of ten free 

 perigynous stamens. The scarcely excentric gynseceum has a pluri- 

 ovulate ovary surmounted by a style which is at first bent on itself 

 and which ends in an obtuse undilated stigmatiferous surface. The 

 pod is turgid, elongated and bivalved. The only known species of 

 this genus is C. racemo-sa Bo J., an unarmed tree from Magadascar 

 whose bipinnate leaves have small and numerous leaflets, and little 

 caducous stipules. The carmine flowers are grouped in a large 

 ramified many-flowered raceme bearing coloured membranous caducous 

 bracts. 



Acrocarpus^ has the subregular flowers of certain species of Poin- 

 ciana, with narrow petals and a central gynseceum ; but the an- 

 droceum consists of but five long exserted alternipetalous stamens. 

 Till recently the only known species of the genus was A. fnivhiifolius; 

 an enormous tree from the mountains of India, with bipinnate leaves, 

 before the expansion of which the flowers come out in large axillary 

 reflexed racemes. A second species, A. grandis, 3 has lately been ob- 

 served in the Indian archipelago. 



Wagatea? was formerly confounded with the large genus Ca-sal- 

 pinia, possessing the same floral symmetry, while the sepals and 

 oblong petals are similarly imbricated ; but the receptacle lined with 

 glandular tissue is different, being deeper and campanulate, and a 

 little contracted towards its mouth, where it bears ten short stamens. 

 Moreover the flowers are sessile on long simple or ramified spikes, 

 the thick rachis being hollowed into pits to receive them. Wagatea 

 consists of one or two interesting species, climbing trees from India 

 and the surrounding regions, 5 which have bipinnate leaves and are 

 covered with prickles.
