Note

Markgraf (Notizbl. Bot. Gart. Berlin-Dahlem 15: 615-619. 1941) re- duced Zschokkea to Lacmellea after concluding that the characters formerly maintaining their separation, i.e., length of the style, level of the insertion of the anthers, and length of the corolla tube, were due simply to different stages of growth. Monachino (Lloydia 7: 275-302. 1944) also transferred Zschokkea to Lacmellea, apparently unaware of Markgraf's earlier reduction. Judging from his later annotation labels, Woodson also agreed with the congeneric status. Lacmellea panamensis (Woodson) Markgraf, Notizbl. Bot. Gart. Berlin-Dahlem 15: 622. 1941.-FIG. 1GB-C.
