Discussion
An inflorescence-axis bract of Orectanthe sceptrum subsp. occidentedis shows a notable lack of mesophyll differentiation. The entire mesophyll consists of thin-walled parenchyma. Small fibrous bundle caps are present on the phloem poles of the veins. Inflorescence-axis bracts of 0. ptaritepuiana showed an identical structure.
