suspieatur À. Gray.  Habitu inflorescentia et staminibus hine Meérosidero hine Myríto accedit, ova-

tubo semper continua est nec lineatransversa (ealycis margine) separata, et, evidenter e calycis limbo 
ut in Calyptranthe nec e petalis formata est, petalis intra calyptram ab ea distinctis. Genus cseternm
