Notes

  1. In a future paper, shortly to go to press, it will be shown that the name Oocephalus lythroides is incorrectly applied to the frequent plant which occurs in the Distrito Federal.

  2. Recent observations on flowers commencing anthesis, revealed that on first opening, the corollas have a pale tube, the upper lip pink on the inner surface and externally cream, the lateral lobes are yellow and the small anterior lobe, before reflexing is orange. From earlier observations, it would appear that the yellow coloration soon fades as the flower matures, leaving the colours listed in the description above. Such coloration is as yet unknown in any other species of Oocephalus.
