LEGUMINOSZ-CHSALPINIEA. 147 
lished Erythrophleum of Arzriius in 1818. Labichea was described 
by Gaupicuaup (1817); Apuleia by Martius (1837); Pappigia by 
Presi (1832); Amherstia by Watiicne (1830). In 1827 Scuorr 
made known Melanozylon and Dimorphandra in the Cure posteriores 
of SpreNGEL’s great work. Vogt, in 1834, established the genera 
Schizolobium and Sclerolobium. Tn his special investigations into the 
Leguminose of Brazil, from 1843 downwards, L. R. Tunasne de- 
scribed Cercidium, Diptychandra, Phyllocarpus, Pterogyne, and Thyla- 
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 Wieut, Burkea by W. Hooxzr, 
Colvillea by Bosur, Elizabetha by ScuomBurek, Daniella by Bunnet, 
Wagatea by Datzet., Prioria by GriseBacn, and Storckiella by 
Sremann. In his endless researches on the Leguminose BrntHaM 
determined the six genera Campsiandra, Dicorynia, Martia, Baikiea, 
Cryptosepalum, and Distemonanthus, besides publishing Berlinia of 
Sonanprr and Batesia of Spruce. Muiquzn, in 1859, made known 
the genus Sindora from Tropical Africa, and we ourselves have since 
1865 determined the five genera Didelotia, Griffonia, Duparquetia, 
Baudouinia, and Brandzeia, besides demonstrating that AuBLET's 
Vouacapoua formed a genus, not identical with Andira as had been 
hitherto maintained, but belonging to the series Sclerolobiea, and 
very near to Batesia. 
Thus the number of uncontested genera which we retain in the 
suborder Cesalpiniee is raised to seventy-two. Their geographical 
distribution is mainly restricted to a zone of 40° on either side of 
the equator. Hence Cesalpiniee belong almost exclusively to the 
very warmest countries, the only exceptions being Cercis, Ceratonza, 
and Gymnocladus, besides some representatives of Gleditschia, Cassia, 
and Casalpinia. There is hardly a single warm country which has 
not species of Cassia, Bauhinia, Cesalpinia, Parkinsonia, Tamarindus, 
Hymenea, and even Dialium 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, Copaifera, 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
