  • Discussion

    Perhaps referable to C. swartzioides sens. lat. is C. rhonhofiana Harms (No- tizbl. Bot. Gart. Berlin 15(1): 46. 1940), described from a specimen (apparently not duplicated) from Amazonian Ecuador (Schultze-Rhonhof3008, †B). The pro- tologue agrees with C. swartzioides, from which it was supposed to differ only in longer (6, not 2-3 mm) bracts, in most respects, but no mention was made of any appendage to the claw of the vexillum, and the flowers were noted in the field as light pink fading pale yellow. New material from the Pastaza valley near Mera is required.
