On the Tree supplying the Sabicu Wood of Cuba; by 



George Bentham, Esq. 



In re-arranging, some years since, the numerous species of Mimose^e, 

 and in endeavouring to fix within more certain limits the various genera 

 wliich modern botanists have established, I was much embarrassed by 

 a small group of West Indian and tropical American species, which 

 partook of the characters of several of the larger genera, and yet would 

 not associate strictly with any one of them. At the same time, I had 

 but very incomplete specimens of most of these anomalous species, and 

 it was with considerable hesitation that I proposed to collect them into 

 a distinct genus, under the name of Lysiloma, What few specimens I 

 have since received, tend however to confirm its main characters. The 

 stamens are indefinite and monadelphous, as in the Ingem, but few in 

 number ; and the pollen appears generally, if not always, to consist of 

 an indefinite number of separate granules, as in Eumimosece. The pods 

 are flat and thin, as in Leucana, Aliizzia, and several Acacia, but it 

 does not, as in those genera, open in two valves. The border remains 

 entire, as in Mimosa and Enlada ; the valves within, closely adhering 

 together round the margins, appear to rot or break away in the centre 

 to allow the escape of the seeds, or in some instances have a tendency 

 to separate into transverse joints, almost as in Mimosa. 



To this group, if we may rely on the collections of Ramon de la 

 Sagra, belongs the Cuban tree which supplies the Sabicu wood now ex-
