This species was cultivated at Kew in 1881 under the name Pleuropetalum costa- 
ricense; but we have not been able to ascertain the origin of the plant, any more than 
who gave it the name. However, there is no doubt that it is a true Plewropetalum ; 
and there is no doubt that it is the same as Melanocarpum sprucei, Hook. f., and a 
true Amarantacea. In the specimens we examined the stamens varied from five 
to eight.
