Gossweiler’s specimens are the only ones which are distinctly perennial. 
They are at the same time very robust with more elongated and loose panicles, 
the racemes being generally exserted by 1-1| in. from the tops of the spatheoles 
and of a slightly greyish colour. Their facies on that account is not quite that 
of ordinary A. pseudapricus^ Yet the structure of the spikelets as to shape 
and size is so like that of the common state that we may assume the difference 
to be due to conditions of habitat or to a slight racial deviation. 
A. apricus, Trin. (A. apricus, var. genuinus, Hack, l.c.) has scantier panicles 
with very slender racemes and slender joints and pedicels, but is in other 
respects very similar to meagre specimens of A. pseudapricus. It seems to be 
confined to tropical America. Hackel’s Indian variety of A. apricus is a 
distinct csespitosc perennial. It is A. ascinodis, C. B. Clarke.
