From the cultural standpoint A. trinerve is interesting 
among the many species cultivated at Kew as being one of a 
group the members of which are attractive on account of the 
bright colour of their fruits. Foremost among these stands 
A. Bakeri, Hook. f., figured at plate 6261 of this work, — 
which has bright crimson berries. ‘Two members of the 
group, A. violaceum, Schott, alluded to above, and A. 
margaritaceum, Baker, agree with the species now figured 
in haying lilac berries. The cultural requirements of the 
plant are those suitable for <A. Scherzerianum, Schott 
(B. M. t. 5319), and a number of other well-known species 
that are grown as ornamental stove-plants.
