Kwebe Hills, 3,000-3,400 ft., flowering in September, Mrs, 
Lugard, 24. 
_ This species is very similar to A, erubescens, Welw., and should 
stand next to that species, from which it differs in having white 
flowers, with the corolla and stamens about twice as long as in that 
species. I have not seen the pod, but describe it from Mrs. 
Lugard’s excellent drawing. 
The fruit of this plant has not been described previously. Accord- 
ing to McCabe it is a tree of about 10 ft. in height, but according 
to Mrs. Lugard it grows to 20 ft. and is “the only thornless Acacia 
found in the country.” The flowers are creamy-white.

I refer this to Albizzia with some hesitation, as the specimen is.

genus, and in foliage somewhat resembles <A. anthelmintica,
