It is worth remark that Bates, 495, where the stamens are 4 and the genus 

 Filetia, is superficially extremely like this plant. 



The present plant does for Chlamydocardia, but wants the characteristic bracts. I 

 think there are 6 equatorial pores to the pollen, which, further, will not do for Isoglossa, 

 whether there are 6 pores or 3.
