lislied Erythrophlceum of Afzelius in 181S. Labichea was described 

 by Gaudictiaud (1817); Apuleia by Marti us (1837); Pceppigia by 

 Pkesl (1832); Amherstia by Wallich (1830). In 1827 Sciiott 

 made known Melanoxylon and Dimorphandra in the Cures posteriores 

 of Sprengel's great work. Vogel, in 1834, established the genera 

 Schizolobium and Sclerolobiiim. In his special investigations into the 

 Leguminosce of Brazil, from 1S43 downwards, L. R. Tulasne de- 

 scribed Cercidium, Biptychandra, Pit pilocarpus, Pteroggne, and Tliyla- 

 canthus. But it is in England and her colonies that the greatest 

 number of new types have been determined and studied during the 

 last forty years — viz., Acrocarpus by Wight, Burkea by W. Hooker, 

 Colvittea by Bojer, Mizabetha by Schomburgk, Daniella by Bennett, 

 Wagatea by Dalzell, Prioria by Gtrisebach, and StorcJciella by 

 Seemann. In his endless researches on the Leguminosa Bentham 

 determined the six genera Campsiandra, Bicorynia, Martia, Baikiaa, 

 Cryptosepalum, and Dislemonanthus, besides publishing Berlinia of 

 Soeander and Batesia of Spruce. Miquee, in 1859, made known 

 the genus Sindora from Tropical Africa, and we ourselves have since 

 18G5 determined the five genera Bidelotia, Griffonia, Bwparquetia, 

 Baudouinia, and Brandzeia, besides demonstrating that Au beet's 

 Vouacapoua formed a genus, not identical with Andira as had been 

 hitherto maintained, but belonging to the series Sclerotobiea, and 

 very near to Batesia. 



Thus the number of uncontested genera which we retain in the 

 suborder CtesaJpiniea? is raised to seventy-two. Their geographical 

 distribution is mainly restricted to a zone of 40° on either side of 

 the equator. Hence Ccesalpinica belong almost exclusively to the 

 very warmest countries, the only exceptions being Cercis, Ceratonia, 

 and Gymnocladus, besides some representatives of Gleditschia, Cassia, 

 and Casalpinia. There is hardly a single warm country which has 

 not species of Cassia, Bauhinia, Cmsalpinia, Parkinsonia, Tatnarindus, 

 Hymencea, and even Bialium and Vouapa. One genus, Apalatoa, is 

 common to tropical America, Asia, and Africa, though by no means 

 equally distributed, being very common in the New World and very 

 rare in the Old. Another genus, Copaifcra, unknown in Asia and 

 Australia, is common to tropical America and Africa. There are 

 twenty-four genera which have as yet been found spontaneous in
