The flattened second sterile flower, placed at a more acute angle with the rhachis than 

 the hermaphrodite one, gives this plant a I'emai-kable appearance, quite distinct from 

 M. Clausseni, to which species alone it approaches. I find in one of Sellow's specimens 

 in herb. Bentham the second perfect hermaphrodite flower, which I had first observed 

 in M. Clausseni.
