SCHOMBURGK’S GUIANA PLANTS. Ti 
approach to Cesalpinice ; and, with very few exceptions, straight 
in the Cesalpiniez. The stamens in Papilionacee are almost 
universally ez, either united or more or less approximated in 
the form of a tube round the ovary. In Cesalpiniee, an in- 
crease or reduction in number, and anomalies in the form and 
arrangement of these organs, are very frequent. The bipin- 
nate leaves of some Cesalpiniee never occur in Papilionacee, 
Under these limitations the Sophoree form the last group 
of Papilionacee, with which the sstivation of the corolla 
unites them; although they approach the Cesalpiniee by their 
embryo, usually straight or nearly so, by their free stamens 
and by their corolla, which though Papilionaceous in æstiva- 
tion, is often scarcely so in the form and proportion of the 
petals. The tribe is distinguished from Podalyriee, by the 
foliage ; from Hedysaree, by the pod ; from the other Papili- 
onaceous tribes, by the stamens. From among the genera 
included in the tribe in my above quoted memoir, Cercis 
must be again rejected to the neighbourhood of Bauhinia, 
where De Candolle had placed it; and Cadia, Layia, and 
Gourliga, must probably be admitted among Sophoree. |

P. 89. var. fruticosa.—A low shrub growing in rocky situa-

character but stature to separate this plant from B. major, a 
tree having a very extensive geographical range and which
