This and the two following species are very remarkable, as 

 being the only ones in the whole genus with glandular peti- 

 oles. Their habit is not unlike that of some Pithecolobia. 

 The flowers appear to me to be those of a Mimosa. I have 

 seen but one pod apparently ripe in which the valves in each 

 article adhere closely together, as in Entada, instead of sepa- 

 rating spontaneously as in most 3Iimosce. If this character 

 should prove constant in the three species, they may perhaps 

 be considered as a distinct genus, and if so, possibly my 

 Entada? myriadinia above referred to may be associated with 

 them. Acacia Giiilandinae? DC. Prodr. ii. 463, of which 

 the number of stamina is not stated, appears from the short 

 character to be near M. micracantha. 



122. M. extensa (sp. n.), glabra, aculeis minimis, pinnis 

 2— 3-jugis distantibus, glandulis petiolorum depressis, foliolis 

 unijugis amplis ovato-falcatis dimidiatis acuminatis nitidis,
