This plant comes nearer to O. apiculatum (Tas. XLV.) than 
any other species of this curious family ; the principal differences 
consisting in its much smaller proportions ; its shorter, denser, 
and more erect branches; in the different shape of the leaves ; 
and above all, in its very pilose calyptra. The operculum I have 
never had the opportunity of examining.
